All-wheel drive (4MATIC)
Your vehicle is equipped with all-wheel drive
(4MATIC). Both, the front and rear axles, are
powered at all times when the vehicle is being
operated. The 4MATIC improves traction in
conjunction with the ESP
®
(Y page 73) and
the Electronic Traction System (ETS/4-ETS)
(Y page 74).

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 473) 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.
It indicates the relative distance between the
vehicle and an obstacle visually and audibly.
The Parktronic system is activated
automatically when you
R
switch on the ignition
and
R
release the electronic parking brake
or
R
start the engine
and
R
shift the automatic transmission into drive
position D, reverse gear R, or neutral
position N
The Parktronic system deactivates at speeds
above approximately 11 mph (18 km/h). At
lower speeds, the Parktronic system switches
on again.
The Parktronic system also deactivates when
you shift the automatic transmission into
park position P or engage the electronic
parking brake and turn off the engine.
The Parktronic system monitors the
surroundings of your vehicle with six sensors
in the front bumper and four sensors in the
rear bumper.
