Pilot Assist steering assistance can be tem-
porarily deactivated and reactivated without
prior warning.
When the turn signals are used, Pilot Assist's
steering assistance will be temporarily deacti-
vated. When the direction indicator is turned
off, steering assistance is reactivated automat-
ically if the lane's edge markings can still be
detected.
If Pilot Assist cannot clearly interpret the
lane's side marker lines or if the camera/radar
sensor is unable for some other reason to
clearly interpret the lane, Pilot Assist will tem-
porarily deactivate steering assistance. How-
ever, the speed and distance warnings will
remain active. Steering assistance will resume
when the side marker lines can once again be
interpreted. In these situations, the driver may

limitations
Pilot Assist functionality may be reduced in
certain situations.
Pilot Assist is a driver support function
designed to simplify driving and assist the
driver in many situations. However, the driver
is always responsible for maintaining a suita-
ble distance to vehicles or objects around it
and ensuring that the vehicle is correctly posi-
tioned in the traffic lane.
WARNING
In some situations, Pilot Assist may have
trouble helping the driver properly or may
be deactivated automatically – we advise
against using Pilot Assist in such cases.
Examples of such situations include:
•
the lane markings are unclear, worn,
missing, cross each other, or there are
multiple sets of road markings.
•
the lane division changes, e.g. when
lanes split or merge, and at off-ramps.
•
when there is road construction and
sudden changes to the road surface,
e.g. when the lines may no longer mark
the correct route.
•
edges or other lines than lane markings
are present on or near the road, e.g.
curbs, joints or repairs to the road sur-
face, edges of barriers, roadside edges
or strong shadows.
•
the lane is narrow or winding.
•
the lane contains ridges or holes.
•
weather conditions are poor, e.g. rain,
snow or fog or slush or reduced visibil-
ity with poor light conditions, back-
lighting, wet road surface, etc.
The driver should also note that Pilot Assist
has the following limitations:
•
High curbs, roadside barriers, tempo-
rary obstacles (traffic cones, safety bar-
riers, etc.) are not detected. Alterna-
tively, they may be detected incorrectly
as lane markings, with a subsequent
risk of contact between the vehicle and
such obstacles. The driver is responsi-
ble for ensuring that the vehicle main-
tains a suitable distance from such
obstacles.
•
The camera and radar sensors do not
have the capacity to detect all oncom-
ing objects and obstacles in traffic
environments, e.g. potholes, stationary
obstacles or objects that completely or
partially block the route.
•
Pilot Assist does not "see" pedestrians,
animals, etc.
•
The steering assistance is limited in
force, which means that Pilot Assist
cannot always help the driver to steer
and keep the vehicle within the lane.
•
In vehicles equipped with Sensus
Navigation
*
, the function is able to use

information from map data, which
could cause variations in performance.
•
Pilot Assist will be switched off if the
speed-dependent power steering
wheel resistance is working at reduced
power, e.g. during cooling due to over-
heating.
WARNING
Pilot Assist should only be used if there are
clear lane lines painted on each side of the
lane. All other use will increase the risk of
contact with nearby obstacles that cannot
be detected by the functions.
WARNING
•
This is not a collision avoidance sys-
tem. The driver is always responsible
and must intervene if the system fails
to detect a vehicle ahead.
•
The function does not brake for people
or animals and does not brake for small
vehicles, such as bikes and motorcy-
cles. Similarly, it does not brake for low
trailers, oncoming, slow-moving or sta-
tionary vehicles and objects.
•
Do not use the function in demanding
situations, such as in city traffic, at
intersections, on slippery surfaces,
with a lot of water or slush on the road,
in heavy rain/snow, in poor visibility, on
winding roads, or on on/off ramps.
The driver can always correct or adjust steer-
ing assistance provided by Pilot Assist by turn-
ing the steering wheel to the desired position.
Steep roads and/or heavy loads
Pilot Assist is primarily intended to be driven
on flat roads. The function may not be able to
maintain the correct time interval to the vehi-
cle ahead when driving down steep hills. The
driver should be extra attentive and prepared
to apply the brakes.
Do not use Pilot Assist if the vehicle is carrying
a heavy load or towing a trailer.
Pilot Assist cannot be activated if a trailer,
bike carrier or similar is connected to the
vehicle electrical system.
Drive mode unavailable
The
Off Road
drive mode cannot be selected
when Pilot Assist is activated.
The function uses the vehicle's camera and
radar sensor, which has certain general
limitations.

Passing assistance
*
Passing assistance can assist the driver when
passing other vehicles. The function can be
used with Adaptive Cruise Control
*
or Pilot
Assist
*
.
When Adaptive Cruise Control or Pilot Assist
is following another vehicle and you indicate
that you intend to pass that vehicle by using
the turn signal
68
, the system will begin accel-
erating toward the vehicle ahead
before
your
vehicle has moved into the passing lane.
The function will then delay a speed reduction
to avoid early braking as your vehicle
approaches a slower-moving vehicle.
The function remains active until your vehicle
has passed the other vehicle.
WARNING
Please note that this function can be acti-
vated in more situations than just passing
another vehicle, such as when a direction
indicator is used to indicate a lane change
or before exiting to another road – the vehi-
cle will then briefly accelerate.
WARNING
•
The function is supplementary driver
support intended to facilitate driving
and help make it safer – it cannot han-
dle all situations in all traffic, weather
and road conditions.

WARNING
The driver should be aware that if condi-
tions suddenly change when using Passing
Assistance, the function may implement an
undesired acceleration in certain condi-
tions.
Some situations should be avoided, e.g. if:
•
the vehicle is approaching an exit in the
same direction as passing would nor-
mally occur
•
the vehicle ahead slows before your
vehicle has had time to switch to the
passing lane
•
traffic in the passing lane slows down
Situations of this type can be avoided by
temporarily putting Adaptive Cruise Control
or Pilot Assist in standby mode.

Collision risk warning from driver
support
The driver support systems Adaptive Cruise
Control
*
and Pilot Assist
*
can help alert the
driver if the distance to the vehicle ahead
suddenly decreases to an unsafe distance.
Collision warning audible signal and symbol
Audible signal at risk of collision
Collision warning symbol
Camera/radar sensor distance monitoring
Adaptive Cruise Control and Pilot Assist use
approx. 40% of the braking capacity. If a sit-
uation requires more braking force than driver
support can provide, and if the driver does not
apply the brakes, a warning light and audible
warning signal will be activated to alert the
driver that immediate action is required.
WARNING
The driver support system only issues a
warning for vehicles detected by its radar
unit – thus, a warning may come after a
delay or not at all. Never wait for a warning.
Apply the brakes when necessary.
Collision warning symbol on the windshield
In vehicles equipped with a head-up display
*
,
a flashing warning symbol will be displayed on
the windshield.
Visual warnings on the windshield may be
difficult to notice in cases of strong sun-
light, reflections, extreme light contrasts,
or if the driver is wearing sunglasses or is
not looking straight ahead.

Switching target vehicles with
driver support
At certain speeds, vehicles with automatic
transmissions and the driver support func-
tions Adaptive Cruise Control
*
and Pilot
Assist
*
can switch target vehicles.
Switching target vehicles
If the target vehicle ahead turns suddenly, there may
be stationary traffic ahead.
When driver support is actively following
another vehicle at speeds
under
30 km/h
(20 mph) and switches targets from a moving
vehicle to a stationary vehicle, driver support
will brake for the stationary vehicle.
WARNING
When driver support follows another vehi-
cle at speeds
over
approx. 30 km/h
(20 mph) and changes target vehicle –
from a moving vehicle to a stationary one –
driver support will
ignore
the stationary
vehicle and instead accelerate to the stored
speed.
•
The driver must then intervene and
apply the brakes.
Automatic standby mode when switching
targets
Driver support disengages and goes into
standby mode if:
•
your vehicle's speed goes under 5 km/h
(3 mph) and driver support cannot deter-
mine if the target vehicle is stationary or if
it is another object, e.g. a speed bump.
•
your vehicle's speed goes under 5 km/h
(3 mph) and the vehicle ahead turns so
that driver support no longer has a vehicle
to follow.

For vehicles without Adaptive Cruise Con-
trol
*
, speed instead increases by +/- 1km/h
(+/- 1 mph) each time the button is
pressed.
Pressing the accelerator pedal
If speed is increased by depressing the accel-
erator pedal while pressing the
(1) button
on the steering wheel, the vehicle's speed
when the button is pressed will be stored as
the set speed.
Temporarily increasing speed using the accel-
erator pedal, e.g. when passing another vehi-
cle, will not affect the setting. The vehicle will
return to the set speed when the accelerator
pedal is released.
Possible speed
Automatic transmission
The driver support functions can follow
another vehicle at speeds from a standstill up
to 200 km/h (125 mph).
Pilot Assist can provide steering assistance
from near-stationary speeds up to 140 km/h
(87 mph).
The lowest speed that can be set is 30 km/h
(20 mph). When following another vehicle,
ACC can monitor that vehicle's speed and
slow your own vehicle down to a standstill,
but it is not possible to set speeds lower than
30 km/h (20 mph).

Setting time interval to the vehicle
ahead
The time interval to the vehicle ahead can be
set for the functions Adaptive Cruise Control
*
,
Pilot Assist
*
and Distance Alert
*
.
Different time intervals to the
vehicle ahead can be selected
and are shown in the instru-
ment panel as 1–5 horizontal
bars. The more bars, the
longer the time interval. One
bar represents an interval of
approx. 1 second to the vehicle ahead. 5 bars
represents approx. 3 seconds.
When the symbol in the instrument panel
shows a vehicle and a steering wheel, Pilot
Assist follows a vehicle ahead at a preset
time interval.
When only a steering wheel is shown,
there is no vehicle ahead within a reasona-
ble distance.
When the symbol in the instrument panel
shows two vehicles, Adaptive Cruise Con-
trol is following the vehicle ahead at a pre-
set time interval.
When only one vehicle is shown, there is
no vehicle ahead within a reasonable dis-
tance.
Controls for setting a time interval.
Reduce the time interval
Increase the time interval
Distance indicator
–
Press the (1) or (2) button to decrease or
increase the time interval.
> The distance indicator (3) shows the
current time interval.
In order to help your vehicle follow the vehicle
ahead as smoothly and comfortably as possi-
ble, Adaptive Cruise Control allows the time
interval to vary noticeably in certain situations.
At low speeds, when the distance to the vehi-
cle ahead is short, Adaptive Cruise Control
increases the time interval slightly.
•
The greater the vehicles' speed, the
greater the distance between them for
a set time interval.
•
Only use the time intervals permitted
by local traffic regulations.
•
If driver support does not seem to
respond with a speed increase when
activated, it may be because the time
interval to the vehicle ahead is shorter
than the set time interval.
WARNING
•
Only use a time interval suitable for the
current traffic conditions.
•
The driver should be aware that short
time intervals give them limited time to
react and act to any unforeseen traffic
situation.
