For further information about approach/
departure angles, see (
Ypage 200). Maximum gradient-climbing
capability
Note that the vehicle's gradient-climbing
capability depends on the off-road conditions
and the road surface conditions.
Vehicles with the ON&OFFROAD
package: the maximum gradient climbing
ability is 100% when the LOW RANGE off-road
gear is selected.
Vehicles without the ON&OFFROAD
package: the maximum gradient climbing
ability is 80%.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep
terrain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS recognizes this and brakes the
wheels accordingly. The rear wheel torque
is increased, making it easier to drive off.
For further information about the maximum
gradient climbing ability, see (Y page 200). Vehicle data for off-road driving

Mounting dimensions
! If you have a trailer tow hitch retrofitted,
changes to the cooling system and drive

The actual noseweight may not be higher than the value which is given. The value can be found
on the trailer tow hitch or trailer identification plates. The lowest weight applies.
The maximum permissible trailer drawbar noseweight is the maximum weight with which the
trailer drawbar can be loaded. Limit for Mercedes-Benz-approved trailer couplings.

dimensions stated in the illustration must not
be exceeded. Trailer tow hitch
