Installing The Ball Coupling - Mercedes-Benz 2016 GL Operator's Manual

Driving tips
If the trailer swings from side to side:
Do not accelerate.
X
Do not counter-steer.
X
Brake if necessary.
X
Maintain a greater distance from the vehi-
R
cle in front than when driving without a
trailer.
Avoid braking abruptly. If possible, brake
R
gently at first to allow the trailer to run on.
Then, increase the braking force rapidly.
The values given for gradient-climbing
R
capabilities from a standstill refer to sea
level. When driving in mountainous areas,
note that the power output of the engine
and, consequently, the vehicle's gradient-
climbing capability, decreases with
increasing altitude.
