Emergency Assist
How it works
Emergency Assist can detect whether
there is inactivity by the driver and can au-
tomatically keep the car within the lane
and stop it altogether if necessary. This
way the system can actively help avoid an
accident or reduce its consequences.
Emergency Assist uses the same sensors as
Adaptive Cruise Control (ACC) and Lane As-
sist. Therefore, carefully read the information
about the ACC
›››
and the Lane
Assist
and take into account the
limitations of the systems and the indications
given in the information.
If the Emergency Assist detects that the driver
does not perform any activity, it requests that
the driver take control of the vehicle. To do
this, it emits optical and acoustic warnings
and causes braking jolts. The seat belt is
tightened (depending on the equipment). The
system slows down the vehicle and keeps it in
its lane.
You can cancel the adjustment at any time
by moving the steering wheel, over-acceler-
ating or braking.
While the emergency assistant is in operation,
other road users are warned as follows:
●
The hazard warning lights are switched on
soon after.
The following happens as soon as the vehicle
stops:
●
The electronic parking brake is activated.
252
Driver assistance systems
The Emergency Assist is only activated if the
following requirements are met:
●
The adaptive cruise control (ACC) must be
switched on .
●
The Travel Assist or the Lane Assist are
switched on.
●
The system has detected a road lane mark-
ing on both sides of the vehicle.
Troubleshooting
Emergency Assist not available
The control lamp switches on yellow. A rele-
vant warning is also displayed on the instru-
ment panel screen.
●
The field of vision of the camera is dirty.
Clean the windscreen.
●
The visibility of the camera is diminished
due to weather factors, e.g. snow, or deter-
gent residue or some coating. Clean the
windscreen.
●
The visibility of the camera is diminished
due to accessories or adhesives. Leave the
area around the camera’s field of vision free.
●
The camera has been altered or damaged,
e.g. because of damage caused to the wind-
screen. Check for visible damage.
●
There is a fault or a defect. Turn the drive
system off and on again.
●
If the fault continues, disconnect the Emer-
gency Assist and consult a specialised work-
shop.
WARNING
The smart technology fitted into the Emer-
gency Assist cannot overcome the limits
imposed by the laws of physics; it only
works within the limits of the system. The
driver is responsible for driving the vehicle.
●
Adapt your speed and safety distance to
the vehicle in front of you at all times to suit
the visibility, weather, road and traffic con-
ditions.
●
The Emergency Assist cannot always
avoid accidents or serious injuries by itself.
●
If possible, do not wear gloves while driv-
ing. The system could interpret this as no
driving activity.
●
If the radar sensor or the camera are cov-
ered or have been altered or damaged, the
system may intervene on the brakes or on
the direction in an inappropriate manner.
●
The Emergency Assist does not react to
people or animal or vehicles crossing your
path or which approach you head-on in the
same lane.
WARNING
If the Emergency Assist Intervenes inoppor-
tunely, serious accidents and injuries may
occur.
●
If the vehicle behaves differently than ex-
pected, interrupt the intervention of the
Emergency Assist by over-accelerating,
braking or moving the steering wheel.
●
Do not use Travel Assist or Lane Assist.
Have the system checked by a specialised
workshop.
Note
●
Automatic interventions by the Emergen-
cy Assist on the brakes may be interrupted
by pressing the accelerator or brake or by
moving the wheel.
●
Hazard warning lights that come on auto-
matically can be switched off by pressing
the accelerator or the break, moving the
steering wheel or pressing the hazard
warning light switch.
●
If this occurs, the Emergency Assist may
decelerate the vehicle until it comes to a
complete stop.
●
When the Emergency Assist is activated,
it is only available again after the ignition
has been switched off and back on again.

Driving
Side Assist with Rear Cross
Traffic Alert (RCTA)
Introduction
The lane departure warning (LCA) helps
detect traffic that is at the rear of the vehi-
cle.
The rear cross traffic alert (RCTA) helps
the driver when backing out of a parallel
parking spot and when manoeuvring.
WARNING
The smart technology incorporated into
the blind spot detector (BSD) with parking
assistance (RCTA) included cannot over-
come the limits imposed by the laws of
physics; it only works within the limits of the
system. Accidents and severe injury may
occur if the blind spot detection system or
the rear cross traffic alert are used negli-
gently or involuntarily. The system is not a
replacement for driver awareness.
●
Adapt your speed and safe distance to
the vehicle in front of you at all times to suit
visibility, weather, road and traffic condi-
tions.
●
Keep your hands on the wheel at all times
to be ready to intervene in the steering at
any time.
●
Pay attention to the indicator lamps that
may come on in the external rear view mir-
rors and on the instrument cluster, and fol-
low any instructions they may give.
●
The lane departure warning could react
to any special constructions that might be
present to the sides of the vehicle, e.g. high
or irregular dividers. This may cause erro-
neous warnings.
●
Never use the lane departure warning on
unpaved roads. The lane departure warn-
ing has been designed for use on paved
roads.
●
Always pay attention to the vehicle's sur-
roundings.
●
The control lamps of the lane departure
warning may have limited functionality due
to solar radiation.
Note
If the blind spot detector with parking as-
sistant does not work as described in this
chapter, stop using it and contact a speci-
alised workshop.

Driver assistance systems
It lights up
It turns on once briefly: the lane departure warning is
activated and ready to operate, i.e. when activating
the system.
It lights up continuously: the lane departure warning
has detected a vehicle in the blind spot.
Flashes
A vehicle has been detected in the adjacent lane and
the turn signal has been engaged in the direction of
the detected vehicle
For vehicles that are also equipped with Lane Assist
, a warning to switch lanes will also ap-
pear even though the turn signal has not been en-
gaged (Lane Assist “Plus”
).
The control lamps light up when the ignition is
switched on and should turn off after approxi-
mately 2 seconds. This is the time taken for
the function check.
If there are no indications from the control
lamp of the lane departure warning, this
means that the lane departure warning has
not detected any other vehicles at the rear
area
When the exterior lighting is low, the intensity
with which the control lamps come on is dim-
med. The user can modify the intensity of the
control lamps with up to 5 levels in the info-
tainment system menu.
WARNING
If the warning lamps and the corresponding
messages are ignored when they light up,
the vehicle may stall in traffic and cause
accidents and severe injuries.
●
Never ignore the warning lamps or mes-
sages.
●
Carry out the necessary operations.
CAUTION
Failure to heed the control lamps and cor-
responding text messages when they light
up may result in damage to the vehicle.
Lane departure warning (Side As-
sist)
The lane departure warning uses radar sen-
sors to monitor the areas behind the vehicle
›››
. The system does this by measur-
ing the vehicle's distance from other vehicles
and its speed differential. The lane departure
warning will not work at speeds of less than
approx. 15 km/h (9 mph). The system uses
optical signals in the external rear view mir-
rors to notify the driver.
The lane width is not detected individually,
but is rather pre-configured in the system.
Thus if you are driving in wide lanes or in be-
tween two lanes, the indications may be in-
correct. Furthermore, the system can detect
vehicles driving in the lane next to you (if
there are any), and can also detect station-
ary objects such as dividers, and thus give an
incorrect indication.
Indication on the exterior mirror
The control lamp provides an indication on
the corresponding side regarding the traffic
situation behind the vehicle, if it is deemed to
be critical. The control lamp of the left-hand
side
indicates the traffic situation
to the rear left of the vehicle, and the control
lamp of the right-hand side
, indi-
cates the traffic situation to the rear right of
the vehicle.
In the case of retrofitted tinted windows or
windows with tinted film, the indications of the
external mirrors may not be seen clearly or
correctly.
Keep the external mirrors clean and free of
snow and ice, and do not cover them with ad-
hesives or other similar materials.
Lane assist Plus.
The Lane Assist Plus function can be used by
activating the
Lane Assist
and
Side Assist
functions. In this case its functions
are expanded as described below.

●
When being overtaken by another vehicle
›››
.
●
When passing another vehicle
with a speed differential of approx. 10 km/h (6
mph). If the vehicle is passing at a considera-
bly higher speed, no indication will be dis-
played.
The faster a vehicle approaches, the sooner
an indication will be displayed in the exterior
mirror, because Side Assist takes into account
the different in speed compared to other ve-
hicles. Thus even though the distance from
the other vehicle is identical, the indication
will appear sooner in some cases and later in
others.
Physical limitations inherent to the system
In some situations the lane departure warning
may not interpret the traffic situation correct-
ly. I.e. in the following situations:
●
on tight bends;
●
in the case of lanes with different widths;
●
in areas with significant gradient changes;
●
in adverse weather conditions;
●
in the case of special constructions to the
side of the vehicle, e.g., high or irregular divid-
ers.

Driver assistance systems
Rear cross traffic alert (RCTA)
Fig. 182
Schematic representation of the rear
cross traffic alert assistant: zone monitored
around the vehicle while leaving a parking
space.
Park Assist uses the radar sensors on the rear
bumper
›››
to monitor the traffic
crossing behind the vehicle as it backs out of
a parallel parking space or as it is being man-
oeuvred, for example in very low visibility con-
ditions.
When the system detects a relevant vehicle
on the road that is approaching the rear of
the vehicle
, an acoustic alarm
may sound if the relevance so requires it.
In addition to the acoustic alarm, the driver is
also informed by means of a visual signal on
infotainment system display. This signal is dis-
played in the form of a red or yellow strip at
the back of the image of the vehicle on the in-
fotainment system screen. This strip displays
the side of the vehicle towards which traffic is
approaching in transverse direction
.
Automatic braking to reduce damages
If the rear cross traffic alert detects that
someone else on the road is approaching the
rear of the vehicle and the driver does not
step on the brake, the system will engage the
brakes automatically.
The parking system helps the driver by auto-
matically engaging the brakes to reduce any
damage. The automatic intervention on the
brakes takes place when driving in reverse at
approx. 1-12 km/h (1-7 mph). After detecting
that the vehicle is stationary, the system
keeps it that way for around 2 seconds.
After automatically braking to reduce dam-
age, the system will not be able to automati-
cally brake again for approximately 10 sec-
onds.
You can interrupt the automatic braking by
stepping hard on the accelerator pedal or
the brake pedal in order to regain control of
the vehicle.
WARNING
The smart technology incorporated into
the rear cross traffic alert cannot over-
come the limits imposed by the laws of
physics; it only works within the limits of the
system. The parking assistant function
should not tempt you into taking any risks.
The system is not a replacement for driver
awareness.
●
The system should never be used in limi-
ted visibility conditions or complicated
traffic, e.g., in high-traffic areas or when
crossing multiple lanes.
●
Be sure to always be aware of the vehi-
cle's surroundings, since the system often
fails to detect things such as bicycles or
pedestrians.
●
The rear cross traffic alert itself will not
brake the vehicle to a complete stop.

●
Side Assist
●
Rear cross traffic alert
If the verification box on the instrument panel
or the infotainment system is checked
, the
functionality will be automatically activated
when switching on the ignition.
When the Side Assist is ready to operate, the
indicator turns on briefly on the exterior rear
view mirrors as confirmation.
When the vehicle is restarted, the last adjust-
ment in the system will remain active.
Trailer mode
Side Assist and the rear cross traffic alert are
automatically deactivated and cannot be
switched on if the factory-fitted tow-bar is
electrically connected to a trailer or similar
device.
As soon as the driver starts to drive with a
trailer connected electrically to the vehicle, a
message is displayed on the instrument pan-
el display indicating that the Side Assist and
the rear cross traffic alert are switched off.
Once the trailer has been unhooked from the
vehicle, if you want to use the Side Assist and
the rear cross traffic alert, you will have to re-
activate them in the corresponding menu.
If the tow-bar is not factory fitted, Side Assist
and the rear cross traffic alert should be
switched off manually when driving with a
trailer.

WARNING
●
When the ignition is switched on, the sta-

sist functions is automatically checked.
The control lights on the instrument cluster
light up briefly and then turn off again. If a
warning light stays on permanently, there
258
Braking and parking
is a fault. Seek qualified technical assis-
tance immediately.
●
If the brake warning lamp
does not go
out or if it lights up when driving, the brake
fluid level in the reservoir is too lo so there
is a risk of an accident
›››
. Stop the vehicle and do not drive on.
Obtain technical assistance.
●
If the brake warning lamp lights up
to-
gether with the ABS lamp
this could be
due to an ABS fault. When this function
fails, the rear wheels can lock up. Under
certain circumstances, the rear of the vehi-
cle may skid, with the danger of losing con-
trol. Stop and seek technical assistance.
●
If the
lamp lights up, alone or accom-
panied by a warning message on the in-
strument panel display, please go immedi-
ately to a specialised workshop to check
the brake pads and to replace them if they
are worn.
Information about the brakes
New brake pads
For the first 200 to 300 km (100 to 200
miles), new brake pads have not yet reached
their maximum braking capacity, and need to
be “run in” first. However, you can compen-
sate for the slightly reduced braking effect by
applying more pressure on the brake pedal.
Avoid overloading the brakes while running
them in.
Wear
The rate of wear on the
brake pads
depends
a great deal on how you drive and the condi-
tions in which the vehicle is operated. This is a
particular problem in urban traffic and short
stretches, or with very sporty driving.
Depending on the speed, the braking force
and the environmental conditions (e.g. tem-
perature, air humidity, etc.) noises may be
produced when braking.
Wet roads or road salt
In certain situations (for example, on driving
through flooded areas, in severe downpours
or after washing the vehicle) the braking ac-
tion could be delayed if the discs and pads
are damp, or frozen in winter. In this case the
brakes should be “dried” by pressing the
brake pedal several times.
At high speed and with the windscreen wipers
activated, the brake pads will briefly touch
the brake discs. This takes place, although
unnoticeable to the driver, at regular intervals
to improve the response time of the brakes
when they are wet.
The effectiveness of the brakes can also be
temporarily reduced if the vehicle is driven for
some distance without using the brakes when
there is a lot of salt on the road in winter. The
layer of salt that accumulates on the discs
and pads can be removed by gently apply-
ing the brakes a few times.
Corrosion
There may be a tendency for corrosion to
form on the discs and dirt to build up on the
brake pads if the vehicle is used infrequently
or the brakes are not used very often.
If the brakes are not used frequently, or if rust
has formed on the disks, it is advisable to
clean off the pads and disks by braking firmly
a few times at a moderately high speed
.
Fault in the brake system
If the brake pedal travel should ever increase
suddenly
, this may mean that one of the two
brake circuits has failed. Drive immediately to
the nearest specialised workshop and have
the fault repaired. Drive there slowly and re-
member that you will have to apply more
pressure on the brake pedal and allow for
longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if
the brake fluid level is too low. The brake fluid
level is monitored electronically.
»
259
Driving
Brake servo
The brake servo increases the pressure you
apply to the brake pedal. It works only when
the engine is running.
WARNING
Any anomaly in the brake system can in-
crease the braking distance, with the re-
sulting risk of an accident.
●
New brake pads and discs must be run in
and do not have the correct friction during
the first 200 km (124 miles). This reduced
braking capacity may be offset by pressing
on the brake pedal a little harder.
●
If you are driving on roads which have
been salted, braking effectiveness may be
decreased.
●
Brakes can overheat if used excessively
on slopes. Before driving down a long steep
slope, it is advisable to reduce speed and
change down into a lower gear or range.
Therefore, using the engine brake relieves
the brakes.
●
Gentle continuous braking causes the
brakes to overheat and the braking dis-
tance will increase. Apply and then release
the brakes alternately.
●
Apply the brakes heavily to clean the
brake system only in a suitable traffic situa-
tion. Do not put other road users in danger:
there is risk of causing an accident.
●
Ensure the vehicle does not move while in
neutral, when the engine is stopped. The
braking distance is increased considerably
when the brake servo is not active.
●
If the brake is subjected to high stresses,
vapour bubbles may form in the brake sys-
tem's pipes. This reduces the efficiency of
the brakes.
●
Non-standard or damaged front spoilers
could restrict the airflow to the brakes and
cause them to overheat. Before purchasing
accessories please read the relevant in-
structions.
CAUTION
●
Never let the brakes “drag” by leaving
your foot on the pedal when it is not neces-
sary to brake. This overheats the brakes, re-
sulting in longer stopping distances and
greater wear.
●
Before driving down a long, steep gradi-
ent, it is advisable to reduce speed and se-
lect a lower gear. This makes use of engine
braking and relieves the brakes. If you still
have to use the brakes, it is better to brake
firmly at intervals than to apply the brakes
continuously.
Note
●
If the brake servo is out of action, for ex-
ample when the car is being towed, you will
have to press the brake pedal considerably
harder than normal to make up for the lack
of servo assistance.
●
If you wish to equip the vehicle with ac-
cessories such as a front spoiler or wheel
covers, it is important that the flow of air to
the front wheels is not obstructed, other-
wise the brakes can overheat.

Automatic release of the electronic park-
ing brake upon moving off
The electronic parking brake is automatically
switched off when starting if, after the driver's
door is closed and the driver's seat belt fas-
tened,
any
of the following situations take
place:
●
In vehicles with automatic gearboxes:
a
gear is engaged or changed to another and
the accelerator is pressed gently.
●
In vehicles with manual gearboxes:
the
clutch pedal is pressed fully before starting
off and the accelerator is pressed gently.
●
To facilitate certain manoeuvres there are
exceptions that allow the automatic parking
brake to be released without the driver's seat
belt being fastened.
The parking brake can be prevented from be-
ing automatically released by continuously
pulling up the
switch when
starting off.
The electronic parking brake is not discon-
nected until the
button is released. This
can facilitate starting off when a heavy load
is towed
.
Automatic activation of the electronic
parking brake when exiting the vehicle in-
correctly
In vehicles with automatic transmission, the
electronic parking brake is activated auto-
matically when exiting the vehicle incorrectly
if:
●
The selector lever is in the
D/S
or
R
position
or in the Tiptronic selector gate.
●
AND:
the vehicle is stationary.
●
AND:
the driver door is open.

the same time, an acoustic warning can be
heard.
●
To stop the braking process, release the
button or press the accelerator.
WARNING
The improper use of the electronic parking
brake can cause accidents and serious in-
jury.
●
Never use the electronic parking brake to
stop the vehicle, unless it is an emergency.
Braking distances can be considerably lon-
ger, since, under certain circumstances,
only the rear wheels brake. Always use the
foot brake.
●
Never accelerate from the engine when a
gear range or a gear is engaged and the
engine is running. The vehicle could move,
even if the electronic parking brake is acti-
vated.
●
When the electronic parking brake is
switched on or off, there is a slight move-
ment of the brake pedal. Be careful not to
position your foot under the pedal.
CAUTION
To prevent the vehicle from unintentionally
moving when parking it, first apply the
electronic parking brake and then remove
your foot from the brake pedal.

Once connected, the Auto Hold function as-
sists the driver in keeping the vehicle station-
ary at repeated intervals or for a certain peri-
od of time with the engine running, for exam-
ple, when going up a slope, when stopped at
traffic lights or in heavy traffic with intermit-
tent stops.
When connected, the Auto Hold function au-
tomatically prevents the vehicle from rolling
when stationary without pressing the brake
pedal.
After detecting that the vehicle is stationary
and the brake pedal has been released, the
Auto Hold function holds the vehicle. The driv-
er can lift their foot off the brake pedal.
When the driver touches the accelerator
pedal or accelerates slightly to continue driv-
ing, the Auto Hold function releases the brake.
The vehicle moves according to the slope of
the road.
If the vehicle is stationary and one of the con-
ditions required by the Auto Hold function is
impaired, it disconnects itself and the button's
control light goes out

ground, e.g. in the case of axle articula-
tion.
WARNING
The smart technology incorporated into
the Auto Hold function cannot defy the
laws of physics; it only works within the lim-
its of the system. The greater convenience
provided by the Auto Hold function should
never tempt you to take any risk that may
compromise safety.
●
Never leave the vehicle running and with
the Auto Hold function switched on.
●
The Auto Hold function cannot always
keep the vehicle stationary uphill or down-
hill or stop it sufficiently, for example, on
slippery or frozen surfaces.
Note
Before entering a car wash, always switch
off the Auto Hold function, because if the
electronic parking brake is automatically
connected, it may cause damage.

Brake assist systems
Electronic Stability Control (ESC)
The ESC helps to improve safety. It reduces
the tendency to skid and improves the stabili-
ty and roadholding of the vehicle. The ESC
detects critical handling situations, such as
vehicle understeer or oversteer, or wheelspin
on the driving wheels. It stabilises the vehicle
by braking individual wheels or by reducing
the engine torque. The warning lamp will
flash on the instrument panel when the ESC is
intervening
.
The ESC includes the anti-lock brake system
(ABS), the hydraulic brake assist (HBA), the
traction control system (ASR), electronic dif-
ferential lock (EDS), electronic torque control
(XDS) and tractor-trailer sway mitigation.
ESC also helps stabilise the vehicle by
changing the torque.
The ASR can be deactivated when wheel spin
is desirable
›››
.
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up un-
der braking until the vehicle has reached a
virtual standstill. You can continue to steer the
vehicle even when the brakes are on full.
Keep your foot on the brake pedal and do not
pump the brakes. You will feel the brake pedal
pulsate while the ABS is working.
If the running gear or brake system is modi-
fied, the effectiveness of the ABS could be se-
verely limited.
Hydraulic Brake Assist (HBA)
The brake assist system can reduce the re-
quired braking distance. The braking force is
automatically boosted if you press the brake
pedal quickly in an emergency. You must
keep pressing the brake pedal until the dan-
ger has passed.
Traction control system (ASR)
In the event of the wheels spinning, the ASR
reduces the engine torque to adapt to the
road condition. This helps the car to start
moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes
the spinning wheel and directs the power to
the other driven wheel. This function is active
up to approximately 100 km/h (62 mph).
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automati-
cally if subjected to excessive loads. The ve-
hicle can still be driven. The EDL will switch on
again automatically when the brake has
cooled down.
Tractor-trailer sway mitigation
If the vehicle is pulling a trailer, it will control
the following: tractor-trailers tend to sway.
When the swaying of the trailer is felt by the
vehicle and detected by the ESC, it will auto-
matically brake the towing vehicle within the
limits of the system and mitigate the sway.
Tractor-trailer sway mitigation is not available
in all countries
›››
.
Electronic engine torque management
(XDS)
When taking a curve, the driveshaft differen-
tial allows the outer wheel to turn at a higher
speed than the inner wheel. In this way, the
wheel that is turning faster (outer wheel) re-
ceives less drive torque than the inner wheel.
This may mean that in certain situations the
torque delivered to the inner wheel is too
high, causing the wheels to spin. On the other
hand, the outer wheel is receiving a lower
drive torque than it could transmit. This can
cause a loss of grip on the drive axle, in this
case the front axle, which results in under-
steer or “lengthening” of the trajectory.
The XDS can detect and correct this effect
via the sensors and signals of the ESC.
Via the ESC, the XDS will brake the inside
wheel and counter the excess driving torque
264
Braking and parking
of that wheel. This means that the requested
trajectory is much more precise.
XDS works in combination with the ESC and is
always active, even when ASR is switched off,
or when the ESC is in Sport mode or discon-
nected.
Multi-collision brake
The multi-collision brake consists of automat-
ic braking activated by the Airbag control
unit. It is activated when, in the event of an
accident, the Airbag control unit detects de-
celerations above the activation level, and
braking is managed by the ESC system.
In the event of an accident, the multi-collision
brake can help the driver by braking to avoid
the risk of skidding during the accident and
causing other collisions.
The following actions control automatic brak-
ing during the accident:
●
When the driver presses the accelerator,
the automatic braking does not take place.
●
When the braking pressure through press-
ing the brake pedal is greater than the sys-
tem’s braking pressure the vehicle will brake
automatically.
●
Multi-collision braking will not be available
if there is an anomaly in the ESC system.
WARNING
Driving at high speed on icy, slippery wet
ground can result in loss of vehicle control
and serious injury to the driver and passen-
gers.
●
The ESC, ABS, ASR, EDS or electronic tor-
que management are not in a position to
overcome the limits imposed by physics.
Always bear this in mind, especially on wet
or slippery roads. If you notice the systems
cutting in, you should reduce your speed
immediately to suit the road and traffic
conditions. Do not be encouraged to take
risks by the presence of more safety sys-
tems. If you do, an accident may occur.
●
Please remember that the accident risk
always increases if you drive fast, espe-
cially in corners or on a slippery road, or if
you follow too close behind the vehicle in
front of you. The ESC, ABS, brake assist,
EDS and the electronic torque control sys-
tem cannot prevent accidents: risk of acci-
dents!
●
Accelerate with caution on slippery sur-
faces (for example, icy or snow-covered).
Despite the control systems, the driven
wheels could spin, affecting the stability of
the vehicle: risk of accident!
Note
●
The ABS and ASR will only operate cor-
rectly if the four wheels have identical
tyres. Any differences in the rolling radius
of the tyres can cause the system to re-
duce engine power when this is not desired.
●
The regulating processes of the systems
can make noises due to their operation.
●
If the warning lamp
or
lights up,
there could be a fault
.
●
Any modifications made to the vehicle
(for example, to the engine, brake system,
running gear or to the combination of
wheels and tyres) may affect the operation
of the ABS, ASR and EDS.
Connecting and disconnecting the
ESC and ASR
The ESC is switched on automatically when
the engine is started, and only works when
the engine is running and includes the ABS,
EDS and ASR systems.
The ASR function should only be switched off
in situations where traction is insufficient.
Depending on the finishes and versions, it is
possible to only switch off the ASR, or to
switch on the ESC in “Sport” mode.
Switching the ASR off and on
●
The ASR can be switched off and on using
the infotainment system
. In vehi-
cles with a driver information system the cor-
responding indication will be displayed.

Driving
When the ASR is switched off, the indicator
lamp
lights up on the instrument cluster.
Disconnecting and connecting the ESC in
“Sport” mode
●
In “Sport” mode, the ESC can be discon-
nected and connected using the infotainment
system
. In vehicles with a driver
information system the corresponding indica-
tion will be displayed.
When “Sport” mode is connected, the inter-
ventions of the ESC to stabilise the vehicle,
and the anti-slip regulation (ASR
) interven-
tions are limited. In addition, the
control
lamp lights up on the instrument panel.
ESC in “Offroad” mode
Turn the Driving Experience button to select
the Offroad mode and connect it
›››
. The interventions of the ESC, as
well as of the ASR, EDS and the ABS, adapt to
irregular terrain.
In the following exceptional situations it may
make sense to activate the Offroad mode to
allow the wheels to spin:
●
When “swinging” the vehicle to get it un-
stuck.
●
Driving in deep snow or on loose surfaces.
●
When driving on rough terrain with much of
the car's weight is lifted off the wheels (axle
articulation).
●
Steep descents with braking on unpaved
terrain.
For your safety we recommend that you turn
off the Offroad mode when it is not absolute-
ly necessary.
To
disconnect
the “Offroad” mode, select a
different driving mode.
ESC in “Snow” mode
Turn the Driving Experience button to select
the “Snow” mode and connect it
›››
. Traction control system (ASR)
interventions adjust to the adhesion of snowy
roads.
To
disconnect
the “Snow” mode, select a dif-
ferent driving mode.
WARNING
The ESC Sport mode should be activated
only when traffic conditions and the ability
of the driver allow it. Danger of skidding!
●
With ESC in Sport mode, the stabilising
function will be limited to allow for a sporti-
er drive. The driving wheels could spin and
the vehicle could skid.
WARNING
You should only activate the Offroad Mode
or disable the ASR if the driver is experi-
enced and if permitted by the traffic condi-
tions. Danger of skidding!
●
The stabilisation function is limited when
the Offroad profile is switched on. In partic-
ular, if the road is too smooth and slippery,
the driving wheels could spin and the vehi-
cle could skid.
Note
If the ASR is switched off or the Sport mode
is selected, the cruise control is switched
off.
1)
In vehicles with 4-wheel drive, the ASR is dis-
connected completely
2)
Only for 4Drive models.

●
With a manual gearbox, engage first gear
on flat ground and slopes, or even reverse
gear on hills, and release the clutch pedal.
●
When leaving the vehicle, take all keys with
you.
Additionally, on steep slopes and inclines
Before switching off the engine, rotate the
steering wheel so that if the vehicle should
move, it will be held by the kerb.
●
On slopes, turn the front wheels so that
they are against the edge of the kerb.
●
Uphill, turn the wheels towards the centre of
the road.
WARNING
●
Avoid parking the vehicle where the hot
exhaust system could ignite inflammable
materials, such as dry grass, low bushes,
spilt fuel or flammable materials.
●
Do not leave passengers inside a closed
vehicle, they may not be able to open
doors or windows. Locked doors hinder the
possibility of a rescue.
●
Children should not be left alone in the
vehicle. They could tamper with the hand-
brake or the gears, which could cause the
vehicle to move without control.
●
Depending on weather conditions, it may
become extremely hot or cold inside the
vehicle. This can be fatal.

Assisted parking system
(Park Assist)
Introduction
The parking assist system is an additional
function of the ParkPilot
and
helps the driver find a suitable parking space
from among the following types:
●
park driving in reverse in suitable perpen-
dicular and parallel spaces,
●
park driving forwards in suitable perpendic-
ular spaces,
●
exit a parking space driving forwards from a
parallel space.
In vehicles with a Park Assist system and fac-
tory infotainment system, the front, rear and
side areas are represented, and the position
of obstacles is shown relative to the vehicle.
The Park Assist system is subject to certain
limitations inherent to the system and its use
requires special attention by the driver
