Recommendations for using a trailer
Adjust the tyre pressure on the vehicle for full load.
▶
Do not exceed the maximum permissible total
weight of the vehicle and the combination weight
specified in the technical vehicle documentation
(e.g. in the vehicle registration documentation, in
the COC document) and on the type plate.
For trailer operation, consider the current load con-
dition of the vehicle as well as the distribution of
the load in the trailer. The coupled trailer increases
the rear axle load and can therefore reduce the
payload.
Adjust the headlight range of the headlights ac-
cording to the load status of the vehicle. The front
of the vehicle may lift up when a trailer is being
towed and the headlights may dazzle other road
users.

Tips for economical driving
Avoid unnecessary acceleration and braking.
▶
A speed of 100 km/h should not be exceeded.
▶
▶
Follow the gear recommendation in the display of
the instrument cluster.
▶
Reduce the speed by releasing the accelerator
pedal as soon as a pendulum movement of the
trailer is noticeable. Never attempt to stop the
trailer from swaying by accelerating.
If the traffic area behind the trailer can not be
viewed, install additional exterior mirrors.
Apply the brakes in good time. If the trailer is fitted
with a trailer brake, apply the brakes gently at first,
then brake firmly. This will avoid brake jolts result-
ing from the trailer wheels locking.
Select a lower gear before descending to also use
the braking force of the engine.
Avoid full acceleration and too high speeds.
Avoid engine idling during longer periods of sta-
tionary time.
