All-wheel drive (4MATIC)
In vehicles with all-wheel drive (4MATIC),
both axles are powered at all times when the
vehicle is being operated. The 4MATIC
improves traction in conjunction with the ESC
( Y page 66) and the Electronic Traction
System (ETS/4-ETS) ( Y page 67).
GWarning!
If a drive wheel is spinning due to insufficient
traction:
R While driving off, apply as little throttle as
possible.
R While driving, ease up on the accelerator
pedal.
R Adapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The 4MATIC cannot prevent accidents
resulting from excessive speed.
! Do not tow with one axle raised. Doing so
could damage the transfer case, which is
not covered by the Mercedes-Benz Limited
Warranty. All wheels must be on or off the
ground. Observe instructions for towing the
vehicle with all wheels on the ground.
! Only conduct operational or performance
tests on a two-axle dynamometer. If such
tests are necessary, contact an authorized
Mercedes-Benz Center. You could
otherwise seriously damage the brake
system and/or the transfer case which is
not covered by the Mercedes-Benz Limited
Warranty.
i In winter operation, the maximum
effectiveness of the 4MATIC is only
achieved with winter tires ( Y page 432) or
snow chains as required.

GWarning!
The ATTENTION ASSIST is only an aid to the
driver. It might not recognize fatigue or
increasing inattentiveness in time or fail to
recognize them at all. The system cannot
substitute a rested and attentive driver.
Fatigue can cause you to recognize dangers
too late, to misjudge potential dangers, or to
react slower. Therefore, make sure to be
rested before and during your trip. Take rests
early enough and regularly, especially during
long trips. Failure to do so could cause you to
recognize dangers too late which could result
in an accident and serious injury to you and/
or others.
The ATTENTION ASSIST interprets your
fatigue or increasing inattentiveness
considering the following criteria:
Rthe individual driving style, for example the
way you steer
Rthe driving conditions such as time of day
and duration of the ride
The ATTENTION ASSIST function is restricted
and warnings will be delayed or not issued at
all when
Rroad conditions are bad, e.g. heavy bumps
or potholes
Rcrosswinds are strong
Rdriving in a sporty manner with high speed
in curves or rapid acceleration
Rdriving slower than 50 mph (80 km/h) or
faster than 112 mph (180 km/h) most of

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.

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.

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
