is greate rtha n1 00 km/h.
When towing atrailer, your vehicle's handling
characteristics will be differen ttowhen driving
without atrailer and th evehicle will consume
mor efuel.
Driving tips R
Maintain agreater distance to the vehicle in
front than when driving without atrailer.
R Avoid braking abruptly. If possible, brake gen-
tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
R The values given for gradient-climbing capa-
bilities from astandstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine, and conse-
quently the vehicle's gradient-climbing capa-
bility from astandstill, decrease with increas-
ing altitude.
If the trailer swings from side to side:
X Do not accelerate under any circumstances.
X Do not countersteer.
X Brake, if necessary. Coupling up
atrailer
! Do no
tconnect th etrailer brak esystem (if
th et railer is fitte dwitho ne)d irectly to the
towing vehicle's hydraulic brak esystem,
since this is equipped wit hananti-lock brak-
ing system. Otherwise, neither th ebrakes on
th et ow ing vehicle no rthe brakes on the
trailer will work.
Observ ethe maximum permissible trailer

X Apply th evehicle's parking brake.
X Mak esure that th eautomatic transmission is
in transmission position P.
X Positio nthe trailer on aleve lsurface behind

X Push th ecombinatio nswitch upward sand
downwards and check whether th ecorre- sponding tur
nsignal indicator on the trailer is
flashing.
Ac onnected trailer is only detected when the
electrical connection is established correctly
and when the lighting system is working prop-
erly. The function of other systems, such as
ESP ®
also depends on this. Uncoupling

run brake, you coul dtrap yourh and between
the vehicl eand the trailer drawbar. This poses
ar isk of injury.
Do not uncouple atrailer with an engaged
