All-wheel drive
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 77) and
the Electronic Traction System (4-ETS)
(
Y
page 78).
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 277) or
snow chains as required.
