Driving tips
If th e trailer sw ays, remember thefo llowing
points:
R Do not accelerate under any circums tances.
R Do not counter steer.
R If necessar y,apply the brakes.

When you are driving with a trailer, comply with
th efo llowing points:
R Maintain a greater dis tance than when driving
without a trailer.
R Avoid braking abruptl y.If possible, brake gen‐

R Before driving, check thefo llowing:
- that the trailer tow hit chand ball coupling
are secure
- that the saf ety swit chfor braked trailers is
functioning cor rectly
- that the saf etych ains are secure and
undamaged
- that the electrical connections are secure
- that the lights are functioning cor rectly
- the wheels for dama geand cor rect tire
pressure (/ page 308)
R Adjust the outside mir rors so that you ha ve a
clear view of there ar section of the trailer.
R Ifth e trailer is equipped with an individual
braking sy stem, check before each journey
whe ther the brakes are functioning cor rectl y.
R Ifth e trailer has electronically cont rolled
brakes, pull away carefully wi th theve hicle/
trailer combination. Brake manually using the
brake controller and check whe ther the
brakes are functioning cor rectl y.
R Secu rethe load on the trailer in line with the
re qu irements and rules for load-securing
me thods.
R When driving with a trailer, check at regular
inter vals that the load is secure and that the
lights and brakes are functioning cor rectl y.
R Bear in mind that the handling characteristics
are more uns table when towing a trailer than
when driving without a trailer. Avoid sudden
st eering mo vements.
R The vehicle/trailer combination is heavier,
accelerates more slowl y,has a reduced
climbing ability and an increased braking dis‐
ta nce. It is more susceptible toside winds
and requ ires careful steering.
R If possible, do not brake suddenl y,but rath er
moderately at firs t so that the trailer can acti‐
va te its brakes. Then inc rease the pressure on
th e brake pedal.
R Ifth e automatic transmission shifts between
ge ars on uphill or downhill gradients, restrict
th e shift range. Select shi ftrange 4, 3, 2 or 1.
A lo werge ar and reduced speed decrease the
ri sk of engine damage.
R When driving on a downhill gradient, shift to a
lo we rge ar to use the engine's braking ef fect. Av
oid cons tant braking, as this could cause
th eve hicle brakes and possibly also the
trailer brakes toove rheat.
R Ifth e coolant temp erature increases signifi‐

switched on, switch the air-conditioning sys‐
te m off.
Coolant heat can also be dissipated by
switching the air flow and thete mp erature of

R When overtak ing, pay particular attention to
