WARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.

WARNING
Under no circumstances try to straighten the
vehicle/trailer combination by increasing the
speed.

The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the
maximum permitted speed is. Observe the
legally prescribed maximum speed in the
relevant country.
For certain Mercedes-Benz vehicles, the
maximum permissible rear axle load is
increased when towing a trailer. Refer to the
"Technical data" section to find out whether
this applies to your vehicle. If you utilize any
of the added maximum rear axle load when
towing a trailer, the vehicle/trailer
combination may not exceed a maximum
speed of 60 mph(100 km/h) for reasons
concerning the operating permit. This also
applies in countries in which the permissible
