Load compensation
The vehicle can compensatedifferences in
thevehicle level by raisingorlowering the
rear axle. This is the case, for example, if
people get out or if luggage is being loaded.
Load compensation takes place if:
Radoor or the trunk lid/tailgate is opened
Rthe parked vehicle is unlocked
For larger level changes, the engine must be
running.
4MATIC (permanent four-wheel drive)
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front,for vehicle speed, for braking in good
time and for staying in your lane.
Ifadrive wheel spins due to insufficientgrip:
ROnly depress the accelerator pedalasfar
as necessary when pulling away.
RAccelerate less when driving.
!Never tow the vehiclewith one axle
raised. This may damage the transfer case.
Damageofthis sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remaineitheronthe ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
iIn wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires(M+S tires), with snow
chains if necessary.
4MATIC ensures that allfour wheels are
permanently driven. Together with ESP®,it
improves the traction of yourvehicle
wheneveradrive wheel spins due to
insufficient grip.
