4MATIC
!
Never tow the vehicle with one axle raised.
This may damage the differential. Damage of
this sort is not covered by the Mercedes-Benz
implied warranty. All wheels must remain
either on the ground or be fully raised.
Observe the instructions for towing the vehi-

ground.

spins due to insufficient grip.
If you fail to adapt your driving style, 4MATIC can
neither reduce the risk of an accident nor over-
ride 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
lane.
If a drive wheel spins due to insufficient grip:

In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you
use winter tyres (M+S tyres), with snow
chains if necessary.
DSR
General notes
i
DSR (Downhill Speed Regulation) is only
available for vehicles with the ON&OFFROAD
package.
DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The steeper
the downhill gradient, the greater the DSR brak-
ing effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or non-existent.
DSR controls the vehicle's speed when it is acti-
vated and the transmission is in position h, k
or i. By accelerating or braking, you can

always drive at a higher or a lower speed than
that set on the on-board computer.
Important safety notes
G
WARNING
If the speed driven and the set speed deviate
and you activate DSR on a slippery road sur-
face, the wheels may lose traction. This
increases the risk of skidding and having an
accident.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override
the laws of physics. DSR cannot take account of
road, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not
always be able to keep to the set speed, depend-
ing on road surface and tyre conditions. Select a
set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.

Y
Activating/deactivating DSR
If you activate DSR and no speed has been set,
the vehicle decelerates to 6 km/h.
You can only activate DSR when driving at
speeds below 30 km/h.
