Driving Assistance PLUS package
General notes
The Driving Assistance PLUS package consists
of DISTRONIC PLUS (
Y
page 199), Active Blind
Spot Assist (
Y
page 234) and Active Lane Keep-
ing Assist (
Y
page 237).
Active Blind Spot Assist
General notes
Active Blind Spot Assist uses a radar sensor
system, pointed toward the rear of the vehicle,
to monitor the area to the sides of the vehicle
which the driver is unable to see. A warning dis-
play in the exterior mirrors draws your attention
to vehicles detected in the monitored area. If
you then switch on the corresponding turn sig-
nal to change lane, you will also receive an opti-
cal and audible warning. If a risk of lateral colli-
sion is detected, corrective braking may help
you avoid a collision. Before a course-correcting
brake application, Active Blind Spot Assist eval-
uates the space in the direction of travel and at
the sides of the vehicle. For this, Active Blind
Spot Assist uses the forward-facing radar sen-
sors.
Active Blind Spot Assist supports you from a
speed of approximately 20 mph (30 km/h).
Important safety notes
Active Blind Spot Assist is only an aid and is not
a substitute for attentive driving.
G
WARNING
Active Blind Spot Assist does not react to:
R
vehicles overtaken too closely on the side,
placing them in the blind spot area
R
vehicles which approach with a large speed
differential and overtake your vehicle
As a result, Active Blind Spot Assist may nei-
ther give warnings nor intervene in such sit-
uations. There is a risk of an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.

grill are free of dirt, ice or slush. The rear sensors
must not be covered, for example by cycle racks
or overhanging cargo. Following a severe impact
or in the event of damage to the bumpers, have
the function of the radar sensors checked at a
qualified specialist workshop. Active Blind Spot
Assist may otherwise no longer work properly.
Monitoring area
G
WARNING
Active Blind Spot Assist does not detect all
traffic situations and road users. There is a
risk of an accident.
Always make sure that there is sufficient dis-
tance on the side for other traffic or obstacles.
Active Blind Spot Assist monitors the area up to
10 ft (3.0 m) behind your vehicle and directly
next to your vehicle, as shown in the diagram.
The detection of obstacles can be impaired in
the case of:
R
there is dirt on the sensors or anything else
covering the sensors
R
poor visibility, e.g. due to rain, snow or spray
Vehicles in the monitoring range are then not
indicated.
Active Blind Spot Assist may not detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles at the inner edge of
your lane.
Due to the nature of the system:
R
warnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
R
warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for a prolonged time.

Warning display
:
Warning display
Active Blind Spot Assist is not operational at
speeds below approximately 20 mph (30 km/h).
Vehicles in the monitoring range are then not
indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp : on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
If you select the reverse gear, Active Blind Spot
Assist is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
When Active Blind Spot Assist is activated, gray
radar waves propagating backwards appear
next to the vehicle in the assistance display in
the multifunction display. Above a speed of
20 mph (30 km/h), the color of the radar waves
in the assistance display changes to green ;.
Active Blind Spot Assist is then ready for use.
Visual and acoustic collision warning
If you switch on the turn signals to change lanes
and a vehicle is detected in the side monitoring
range, you receive a visual and acoustic collision
warning. You will then hear a double warning
tone and red warning lamp : flashes. If the turn
signal remains on, detected vehicles are indica-
ted by the flashing of red warning lamp :.
There are no further warning tones.
Course-correcting brake application
If Active Blind Spot Assist detects a risk of a lat-
eral collision in the monitoring range, a course-
correcting brake application is carried out. This
is meant to assist you in avoiding a collision.
G
WARNING
A course-correcting brake application cannot
always prevent a collision. There is a risk of an
accident.
Always steer, brake or accelerate yourself,
especially if Active Blind Spot Assist warns
you or makes a course-correcting brake appli-
cation. Always maintain a safe distance at the
sides.
If a course-correcting brake application occurs,
red warning lamp : flashes in the exterior mir-
ror and a dual warning tone sounds. In addition,
display ; underlining the danger of a side col-
lision appears in the multifunction display.
In very rare cases, the system may make an
inappropriate brake application. A course-cor-
recting brake application may be interrupted at
any time by countersteering slightly or acceler-
ating.
The course-correcting brake application is avail-
able in the speed range between 20 mph
(30 km/h) and 120 mph (200 km/h).

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera : at the top of the windshield. Various
different areas to the front, rear and side of your
vehicle are also monitored with the aid of the
radar sensor system. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available in a speed range
between 40 mph and 120 mph (60 km/h and
200 km/h).
Important safety notes
If you fail to adapt your driving style, Active Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics. Active
Lane Keeping Assist cannot take account of
road and weather conditions. It may not recog-
nize traffic situations. Active Lane Keeping
Assist is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
your lane.
Active Lane Keeping Assist cannot continuously
keep your vehicle in its lane.
G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R
give an unnecessary warning and then
make a course-correcting brake application
to the vehicle
R
not give a warning or intervene
There is a risk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you. Ter-
minate the intervention in a non-critical driv-
ing situation.
The system may be impaired or may not function
if:
R
there is poor visibility, e.g. due to insufficient
illumination of the road, or due to snow, rain,
fog or spray
R
there is glare, e.g. from oncoming traffic, the
sun or reflections (e.g. when the road surface
is wet)
R
the windshield is dirty, fogged up, damaged or
covered, for instance by a sticker, in the vicin-
ity of the camera

R
the radar sensors in the front or rear bumpers
or the radiator trim are dirty, e.g. obscured by
snow
R
there are no, several or unclear lane markings
for a lane, e.g. in areas with road construction
work
R
the lane markings are worn away, dark or cov-
ered up, e.g. by dirt or snow
R
the distance to the vehicle in front is too small
and the lane markings thus cannot be detec-
ted
R
the lane markings change quickly, e.g. lanes
branch off, cross one another or merge
R
the road is narrow and winding
R
there are strong shadows cast on the road
If no vehicle is detected in the adjacent lane and
broken lane markings are detected, no lane-cor-
recting brake application is made.
Warning vibration in the steering wheel
A warning may be given if a front wheel passes
over a lane marking. It will warn you by means of
intermittent vibration in the steering wheel for
up to 1.5 seconds.
In order that you are warned only when neces-
sary and in good time if you cross the lane mark-
ing, the system recognizes certain conditions
and warns you accordingly.
The warning vibration occurs earlier if:
R
you approach the outer lane marking on a
bend.
R
the road has very wide lanes, e.g. a highway.
R
the system recognizes solid lane markings.
The warning vibration occurs later if:
R
the road has narrow lanes
R
you cut the corner on a bend
Lane-correcting brake application
If you leave your lane, under certain circumstan-
ces the vehicle will brake briefly on one side.
This is meant to assist you in bringing the vehicle
back to the original lane.
G
WARNING
A lane-correcting brake application cannot
always bring the vehicle back into the original
lane. There is a risk of an accident.
Always steer, brake or accelerate yourself,
especially if Active Lane Keeping Assist warns
you or makes a lane-correcting brake appli-
cation.
G
WARNING
Active Lane Keeping Assist does not detect
traffic conditions or road users. In very rare
cases, the system may make an inappropriate
brake application, e.g. after intentionally driv-
ing over a solid lane marking. There is a risk of
an accident.
An inappropriate brake application may be
interrupted at any time if you steer slightly in
the opposite direction. Always make sure that
there is sufficient distance on the side for
other traffic or obstacles.
If a lane-correcting brake application occurs,
display : appears in the multifunction display.
The brake application also slightly reduces vehi-
cle speed.
A lane-correcting brake application can be made
after driving over a lane marking recognized as
being solid or broken. Before this, a warning
must be given by means of intermittent vibration
in the steering wheel. In addition, a lane with
lane markings on both sides must be recog-
nized.
In the case of a broken lane marking being
detected, a lane-correcting brake application
can only be made if a vehicle has been detected
in the adjacent lane. The following vehicles can
have an influence on brake application: oncom-
ing traffic, vehicles that are overtaking and vehi-
cles that are driving parallel to your vehicle.
i
A further lane-correcting brake application
can only occur after your vehicle has returned
to the original lane.

PLUG‑IN HYBRID operation
Points to remember
General notes
Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor. In HYBRID mode, the hybrid
drive system automatically selects the most effi-
cient operating mode for every driving situation.
Drive the vehicle in the usual manner.
To save fuel in HYBRID mode, the hybrid drive
system switches off the combustion engine as
often as possible during the journey when power
output requirements are low. When power out-
put requirements are low, the electric motor
powers the vehicle. The combustion engine is
automatically activated when power output
requirements are high. The engine is usually
switched off when the vehicle is stationary. Con-
sequently, there is usually no engine idling as
with combustion engine vehicles.
For pulling away and accelerating, the electric
motor supports the internal combustion engine
using the power stored in the high-voltage bat-
tery. In addition, the power is used for partially
electric driving, operation of the electric coolant
compressor and to support the 12 V on-board
electrical system. In this way the hybrid drive
system helps to reduce your vehicle's fuel con-
sumption.
Observe the driving tips on PLUG-IN HYBRID
operation (
Y
page 251).
Recuperative Brake System
If you release the accelerator pedal when the
vehicle is in motion, overrun recuperation is ini-
tiated. The electric motor is operated as a gen-
erator when in overrun mode and when you
brake. Hybrid technology converts the kinetic
energy of the vehicle into electricity and stores
it in the high-voltage battery.
Observe the important safety notes for the
Recuperative Brake System (
Y
page 44).
Important safety notes
If the engine is switched off by the ECO start/
stop function and you open the driver's door:
R
a message appears in the multifunction dis-
play and
R
a warning tone sounds
Further information (
Y
page 297).
All of the vehicle's systems remain active, if:
R
the vehicle is stationary
R
the combustion engine is switched off and
R
the READY indicator in the instrument cluster
lights up
If you remove your foot from the brake pedal
while in transmission position D or R, the vehicle
may pull away automatically.
Observe the notes on the READY display of the
ECO start/stop function (
Y
page 252).
Vehicles with an electric motor generate much
less driving noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations.
Depending on the vehicle's equipment and
country-specific regulations, the vehicle can be
equipped with Acoustic Vehicle Indication.
Acoustic Vehicle Indication generates a certain
sound at a speed between 0 and 19 mph
(30 km/h). This helps other road users, partic-
ularly pedestrians and cyclists, to hear your
vehicle better. The sound can also be heard
inside the vehicle.
The volume depends on the engine speed. The
faster you accelerate, the louder the sound is. At
a speed of over 19 mph (30 km/h) the sound is
switched off. Above this speed, the natural
sounds from the vehicle are sufficient that it can
be heard in good time by other road users.

In automatic drive program S (
Y
page 250) and
in manual drive program M (
Y
page 250), only
HYBRID operating mode is available.
If you switch from automatic drive program S to
automatic drive program E or E+, HYBRID oper-
ating mode continues to be selected.
If manual drive program M is deactivated, the
automatic transmission shifts:
R
into the automatic drive program that was last
selected
R
into the driving mode that was last selected
Each time the engine is started, HYBRID mode
is automatically selected.
Power meter
The power meter supports you in electric mode
and displays the output obtained.
If you select the E-MODE operating mode, the
instrument cluster will display the power meter
instead of the tachometer.
i
The tachometer appears again if:
R
you select HYBRID, E-SAVE or CHARGE
R
the current state of charge of the high-volt-
age battery is too low to drive the vehicle in
the E-MODE electrical operating mode
The power meter is divided into the following
areas:
R
Limit : (OFF):
If the needle reaches limit :, the electric
motor and the combustion engine are
switched off.
R
Area ; to ? (CHARGE):
This shows the recuperated energy which is
stored in the high-voltage battery as electrical
energy.
The more recuperated energy the high-volt-
age battery has, the further needle ? travels
in direction =. When the needle reaches limit
=, the maximum amount of recuperative
braking power has been reached.
In addition to the recuperative braking power,
the mechanical brakes are activated in the
area between ; and =.
R
Output range of electric motor: ? to A:
The electric output of the electric motor is
displayed here. When the power meter needle
reaches position ?, the electric motor is
operational. With increasing pressure on the
accelerator pedal, the needle moves towards
A.
The output limit of the electric motor A can
be felt via the additional pressure point in the
haptic accelerator pedal.
If you do not press the haptic accelerator
pedal beyond the pressure point, you can
control electric operation, at low speeds, to
only drive in electric mode.
R
Output range of combustion engine: A to B:
The output of the combustion engine and the
electric motor is displayed here. When the
power meter needle reaches position A and
you press the haptic accelerator pedal
beyond the pressure point, then the combus-
tion engine is switched on.
