GWarning!
Please do not forget that your primary
responsibility is to drive the vehicle. A driver’s
attention to the road must always be his/her
primary focus when driving. For your safety
and the safety of others, stop before trying to
remove window fogging or cleaning the
windshield in front of the Night View Assist
Plus camera.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
XRemoving condensation: Check settings
of the climate control and change them, if
necessary ( Y page 363).XSwing the camera cover downward

non-scratching cloth ( Y page 444).
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 236). 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:

Sensor monitoring range
The Blind Spot Assist is able to monitor a
range up to 10 ft (3 m) to the rear and both
sides of the vehicle.
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.

Red warning lamps \000F in the exterior rear
view mirrors come on.
XStart the engine.
Yellow indicator lamps \000F in the exterior
rear view mirrors come on up to a speed of
20 mph (30 km/h).
Above a speed of 20 mph (30 km/h), yellow
indicator lamps \000F go out and the Blind Spot
Assist is active. If the Blind Spot Assist
detects a vehicle in its range, red warning
lamp \000F 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 \000F 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 \000F 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 \000F on the corresponding side of the
vehicle will flash.
GWarning!
Do not change lanes or make turns, while red
warning lamp \000F 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 \000F 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 235). 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 \000F.
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
Rcutting a curve on the inside of the turn
The system does not issue a warning when
Rsteering, braking, or accelerating in a
clearly active manner, e.g. when changing
lanes, passing, exiting a highway
Rcutting a narrow curve
Rmaking a very sharp turn
Ra driving safety system such as the ABS,
the BAS, or the ESC has been activated
When setting the turn signal in either
direction, the warning will be suppressed. The
system will issue a warning if a turn signal has
been on for an extended period of time.
GWarning!
The Lane Keeping Assist does not keep the
vehicle in the lane. The Lane Keeping Assist
is only an aid to the driver and may not always
recognize lane markings properly or fail to
recognize them at all.
The system may be impaired or unavailable
when
Rvisibility is poor, e.g. due to snow, rain, fog,
or heavy spray
Roncoming traffic, sun glare or reflection
from other vehicles
Rthe camera area of the windshield is dirty,
foggy, or otherwise obstructed
Rlane markings are not present
Rlane markings are worn, dark, or covered
e.g. by snow or dirt
Rthe distance to the preceding vehicle is too
short
Rwhen lane markings are ambiguous, for
example in road work sections
Rlane markings change rapidly, e.g. on
highway exits or turn-off lanes
Rlanes are narrow and winding
The Lane Keeping Assist cannot take road and
traffic conditions into account. It is the
driver’s responsibility at all times to be
attentive to road, weather and traffic

R Temperature: 72‡ (22†) ( Y page 367)
R Footwell temperature: 0 ( Y page 214)
R Air flow: focused ( Y page 215)
The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows, the tilt/sliding
sunroof or tilt/sliding panel closed.
Nearly all dust particles, pollutants and odors
are filtered out before outside air enters the
passenger compartment through the air
distribution system.GWarning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.
GWarning!
Follow the recommended settings for heating
and cooling given on the following pages and
in the “COMAND automatic climate control”
section. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.
XKeep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing objects on
the air flow-through exhaust slots below the
rear window.
i If the vehicle interior is hot, ventilate the
interior before driving off, see “Summer
opening feature” (Y page 309). The climate
control will then adjust the interior
temperature to the set value much faster.

Air conditioning
The air conditioning is operational while the
engine is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging.
GWarning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.
The cooling function can be activated or
deactivated via COMAND ( Y page 213).
