All-wheel drive

Notes on all-wheel drive
All-wheel drive ensures permanent drive for all
four wheels, and together with ESP
the traction of the vehicle.
The traction control of the all-wheel drive also
takes place via the brake system. Therefore, the
brake system can overheat during extreme off-
road use. In this case, ease off the accelerator
pedal or stop to allow the brake system to cool
down.
If a driven wheel spins due to insufficient trac‐
tion:

slowly, while the vehicle is in motion.
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow chains
( page 217). Only in this way can the maximum

effect of all-wheel drive be achieved.
Use DSR (Downhill Speed Regulation) when driv‐
ing downhill off-road (

If you fail to adapt your driving style or if you are
inattentive, the all-wheel drive system can neither
reduce the risk of an accident nor override the
laws of physics. The all-wheel drive system can‐
not take road, weather and traffic conditions into
account. The all-wheel drive system is only an
aid. You are responsible for maintaining a safe
distance from the vehicle in front, for vehicle

lane.
* NOTE Risk of damage to the drivetrain
and the brake system
If you operate vehicles with all-wheel drive on
a one-axle test stand, you may damage the
drivetrain or the brake system.
A function or performance test should
#
only be carried out on a two-axle test
stand.
If you wish to operate the vehicle on
#
such a test stand, please consult a
qualified specialist workshop in
advance.
* NOTE Risk of damage to the transfer
case
If you tow the vehicle with a raised axle, the
transfer case can get damaged. Such damage
is not covered by Mercedes-Benz implied war‐
ranty.
Never tow the vehicle with a raised axle.
#
Only tow the vehicle with all wheels on
#
the ground or fully raised.
Note the instructions on towing the
#
vehicle with full contact with the ground
for all wheels.
