Trailer Tow Hitch - Mercedes-Benz GLS Operator's Manual

Accelerate carefully and make sure that the
wheels do not spin when driving on steep ter-
rain.
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 recog-
nizes this and brakes the wheels accordingly.
The rear wheel torque is increased, making it
easier to drive off.

dient climbing ability, see (
