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
ESP
®
(Y page 65) and the Electronic Traction
System (4-ETS) (Y page 65). G
Warning!
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 251) or
snow chains as required. Parktronic system
The Parktronic system is an electronic
parking aid with ultrasonic sensors designed
to assist the driver during parking maneuvers.

or will not function to its full capability if
R the tailgate is open
R it is raining very hard, snowing or foggy
R it is night or you are parking/maneuvering
your vehicle in an area where it is very dark
R the camera is exposed to a very bright white
light R
the immediate surroundings are
illuminated with fluorescent light (the
display may flicker)
R there is a sudden change in temperature,
e.g. if you drive into a heated garage from
the cold (lens condensation)
R the camera lens is dirty or covered
R the rear of your vehicle is damaged
In this case, have the position and setting
of the camera checked by a qualified
specialist workshop. Mercedes-Benz
recommends that you contact a Mercedes-
Benz Center for this purpose.
Do not use the rear view camera in these
situations. Otherwise you could injure
yourself or others and/or damage property
including your vehicle while parking/
maneuvering. G

Warning!
Please note that objects which do not touch
the ground may appear to be further away
than they actually are, for example:
R the bumper of a vehicle parked behind you
R a trailer hitch
R the back of a truck
In such cases, you should not use the
guidelines to judge the distance. You may
misjudge the distance which increases the
risk of impacting the objects.
Even when the object you approach is directly
on the ground do not approach the object any
closer than the red guideline. Red guideline
= indicates an approximate
distance of 10 in (0.25 m) from the rear of the
vehicle. Yellow guidelines ; indicate an
approximate distance of 3 ft (1 m) from the
rear of the vehicle. Blue guidelines :
indicate the approximate width required for
the vehicle.
