available from the police and local
authorities.
Observe the following when towing a trailer:
R
Practice driving around bends, stopping
and backing up at a place where there is no
traffic. This enables you to gain experience
and get used to the new handling
characteristics.
R Before driving, check:
-that the trailer tow hitch and ball
coupling are secure
- that the safety switch for a braked trailer
is functioning properly
- that the safety chains are secure and not
damaged
- that the electrical connections are
secure
- that the lights are working
- that the wheels are in good order and the
tire pressure is correct
R Adjust the exterior mirrors to provide an
unobstructed view of the rear sectio nofthe
trailer.
R If the trailer has electronically controlled
brakes, pull the vehicle/trailer
combination away carefully. Brake
manually using the brake controller and
check that the brakes are working.
R Secure the load on the trailer according to
the applicable specifications and current
standards on securing loads
(Y page 234).
R When driving with a trailer, check at regular
intervals that the load is secured and that
the brakes and lights are working.
R Bear in mind that the handling will be less
stable when towing a trailer than when
driving without one. Avoid sudden steering
movements.
R The vehicle/trailer combination is heavier,
accelerates more slowly and has a
decreased gradient climbing capability and
a longer braking distance.
It is more susceptible to crosswinds and
requires cautious steering. R
If possible, do not brake suddenly, but
rather moderately at first so that the trailer
can activate its brakes. Then increase the
force on the brake pedal.
R If the automatic transmission repeatedly
shifts between gears when driving on
inclines, restrict the shift range. Select shift
range 4,3,2or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
R When driving on a downhill gradient, shift
to a low gear and take advantage of the
engine's braking effect.
Avoid continuous brake application as this
may overheat the vehicle brakes and, if
installed, the trailer brakes.
R If the coolant temperature increases
dramatically while the air-conditioning
system is switched on, switch off the air-
conditioning system.
Coolant heat can also be dissipated by
switching the airflow and the temperature
of the heater/air conditioning to the
maximum level. Open the windows if
necessary.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of your vehicle/trailer
combination you need an additional
distance before you can return to your
original lane. Uncoupling

WARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
