In order to accumulate driving experience and
accustom yourself to the new handling charac-
teristics, practice the following atalocation
where there is no traffic:
RCornering
RStopping
RBacking up
Before driving, check the following:
RTrailer tow hitch
RSafety switch for braked trailers
RSafety chains
RElectrical connections
RLighting system
RWheelsa nd tires
RLoad-securing measures
Adjust the exterior mirrors to provide an unob-
structed view of the rear section of the trailer.
Trailers with electronically controlled
brakes: pullawaycarefully in the vehicle/trailer
combination, brake manually using the brake
controller and check whether the brakes func-
tion correctly.
Check the load securing measures on aregular
basis.
When towing atrailer, you rvehicle's handling
characteristics willbed ifferent in comparison
with when driving withoutat railer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas alargert urning radius
Avoid sudden steering movements.
Avoid braking abruptly. If possible, brake gently
at first to allow the trailer to run on. Then,
increase the braking force rapidly.
When overtaking, pay particular attention to the
extended length of you rvehicle/trailer combi-
nation.
Due to the length of the vehicle/trailer combi-
nation, you require additional road space when
overtaking before you can change back to the
originall ane.
If the automatic transmission repeatedly shifts
betweeng ears on uphill or downhill gradients,
shift to alowerg ear. Driving in
alowerg ear and at areduced speed
decreases the risk of engine damage.
Avoid constant braking. Otherwise,t he vehicle
brakes and possibly also the trailerb rakes may
overheat.
When driving downhill, shift to alowerg ear to
utilize the engine's braking effect.
If the coolant temperature increases dramati-
cally whilet he air-conditioning system is
switched on, switch off the air-conditioning sys- tem.
Coolant heat can also be dissipated by opening
the windowsa
nd sw
itching the ventilation
blower and the interior temperature to the high-
est level.
Decoupling atrailer
GWARNING
If you uncoupl eatrailerwith the overrun
brake engaged,y ou could trap you rhand
betweent he vehicle and the trailerd rawbar.
There is arisk of injury.
Do not uncoupl eatrailerift he overrun brake
is engaged.
!Do not disconnect atraile rwith an engaged
overrun brake. Otherwise,y ourv ehicle could
be damaged by the rebounding of the overrun
brake.
XApply the parking brake.
XMake sure that the automatic transmission is
set to position P.
XSecure the vehicle and trailera gainst rolling
away.
XClose all doors, including the rear door.
XRemove the trailerc able.
XRemove the safety chains, if there are any.
XUncouple the trailer.
