Notes
iIf you drive in countries with left-hand
driving, you must have the headlamps
modified for symmetrical low beams.
Relevant information can be obtained at
any authorized Mercedes-Benz Center.
iVehicles equipped with active Bi-Xenon
headlamps:
The active Bi-Xenon headlamps increase
usable illumination over conventional
headlamps because they follow the
curvature of the road ahead. The beams of
the active Bi-Xenon headlamps shift to
either side according to the vehicle’s
steering angle and speed.

Blind Spot Assist
The Blind Spot Assist uses radar sensors to
monitor the area on both sides of your
vehicle. It will assist you when you change
lanes driving at speeds of above 20 mph
(30 km/h). A red warning lamp will come on
in the exterior rear view mirror as soon as
another vehicle is detected. If you then
activate the corresponding turn signals to
change lanes, the red warning lamp flashes
and warning sounds (collision warning). The
Blind Spot Assist operates using sensors in
the rear bumper.
GWarning!
The Blind Spot Assist is only a driving aid and
may not detect all vehicles.
The Blind Spot Assist may not be able to
detect narrow vehicles such as motorcycles
or bicycles, or it may not detect them until it
is too late.
The monitoring function may be impaired if
your sensors are dirty, subject to heavy spray,
or if visibility is poor due to e.g. snow, rain, or
fog. This can result in vehicles not being
detected or being detected too late.
The Blind Spot Assist cannot detect road,
traffic and weather conditions.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic
conditions and to provide the steering,
braking and other driving inputs necessary to
retain control of the vehicle. Failure to do so
could result in recognizing dangers too late,
possibly resulting in an accident and serious
injury to yourself and others.
In order for the Blind Spot Assist to function,
the radar sensors must be switched on and
operational.
When traveling in Canada in a vehicle not
registered in Canada, you must switch off the
radar sensor system ( Y page 144). Canadian
law does not permit the use of the radar
sensor system for vehicles from outside of
Canada. When you switch off the radar sensor
system, the following functions are
deactivated:
R Blind Spot Assist
R BAS PLUS ( Y page 63)
R PRE-SAFE ®
Brake ( Y page 69)
R DISTRONIC PLUS ( Y page 149)

GWarning!
The Blind Spot Assist monitors certain areas
in the immediate vicinity of your vehicle.
Vehicles approaching and passing at speeds
that exceed the speed of your vehicle
significantly will not be detected. There will be
no warning display and no audible warning.
When driving in a very wide lane, the sensors
may not be able to cover the entire width of
the neighboring lane. Vehicles driving on the
outside of the neighboring lane may not be
detected.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic
conditions and to provide the steering,
braking and other driving inputs necessary to
retain control of the vehicle. Failure to do so
could result in recognizing dangers too late,
possibly resulting in an accident and serious
injury to yourself and others.
When driving in a very narrow lane, the
sensors may detect and display vehicles in the
second lane over. This will be the case if there
are vehicles driving on the inside edge of their
lane.
The system may issue causeless warnings in
the area of guardrails or similar structural
boundaries.
The two Blind Spot Assist sensors are built
into the rear bumper. Make sure that the area
of the bumper around the sensors is free of
dirt, ice and snow. The radar sensors must not
be obstructed, for example, by bicycle
carriers or overhanging luggage.
! In the event of a significant impact or
damage affecting the bumpers, have the
radar sensors checked by a qualified
specialist workshop such as a Mercedes-
Benz Center. Failure to do this can result in
Blind Spot Assist not functioning correctly.

Assist is active. If the Blind Spot Assist
detects a vehicle in its range, red warning
lamp : on the corresponding side of the
vehicle comes on. The warning is issued each
time a vehicle enters the area monitored by
the Blind Spot Assist from behind or from the
side. When you pass another vehicle, the
warning is issued only when the speed
differential is less than 7 mph (12 km/h).

When you shift the automatic transmission in
reverse gear R, yellow indicator lamps : in
the exterior rear view mirrors goes out after
approximately 3 seconds. The Blind Spot
Assist is then not active.
The brightness of indicator lamps/warning
lamps : is controlled automatically
depending on the brightness of the ambient
light.
GWarning!
The Blind Spot Assist is not active at speeds
below approximately 20 mph (30 km/h). The
yellow indicator lamps in the exterior rear
view mirrors are illuminated. You will not be
alerted to the presence of vehicles in the
monitored area at these speeds.
It is the driver’s responsibility at all times to
be attentive to road, weather and traffic
conditions and to provide the steering,
braking and other driving inputs necessary to
retain control of the vehicle. Failure to do so
could result in recognizing dangers too late,
possibly resulting in an accident and serious
injury to yourself and others.
Collision warning
If a vehicle is detected in the Blind Spot Assist
range and you activate the turn signal, a two-
tone warning will sound once. Red warning
lamp : on the corresponding side of the
vehicle will flash.
GWarning!
Do not change lanes or make turns, while red
warning lamp : is flashing. Doing so could
result in an accident and serious injury to
yourself and others.
XRemain on the lane that you are currently
on until traffic conditions permit to change.
If the turn signal remains on, red warning
lamp : will flash to indicate that vehicles
have been detected. No further audible
warnings will sound.
Lane Keeping Assist
The Lane Keeping Assist supports you at a
vehicle speed of above 40 mph when you
have set the display unit to miles in the
Display Unit Speed-/Odometer: menu in
the control system (Y page 141). When you
have set the display unit to km, the system
supports you at a vehicle speed of above
60 km/h. When the Lane Keeping Assist
detects lane markings, the system is
designed to alert you in case you leave your
lane unintentionally. A warning is usually
issued when a front wheel is on the lane
marking. An interval vibration in the steering
wheel that lasts for up to 1.5 seconds will
then alert you.
The Lane Keeping Assist monitors the area in
front of your vehicle via camera :.
The system can distinguish various
conditions in order to alert you early enough
and to avoid unnecessary warnings when
crossing lane markings.
The warning is issued sooner when
Rcutting a curve on the outside of the turn
Rdriving on very wide lanes such as highway
lanes
Rthe system recognizes dividing lines
because crossing them is often crucial due
to soft shoulders or guardrails behind for
example
The warning is issued later however when
Rdriving on narrow lanes
