General notes
Only vehicles with automatic climate control
have the residual heat function.
Once the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.

another area of the vehicle interior.
The center and side air vents are adjustable.
The air vents can also be adjusted on vehicles
with rear-compartment air conditioning.
In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
Rkeep the air inlet between the windshield and

RWhen driving withatrailer, check at regular
intervals that the load is secured and that the
brakes and lights are working.
RBear in mind that the handling will be less
stable when towing atrailer than when driving
without one. Avoid sudden steerin gmove-
ments.
RThe vehicle/trailer combination is heavier,
accelerates more slowly and has adecreased
gradient climbing capability and alonger
braking distance.
It is more susceptible to crosswinds and
requires cautious steering.
RIf possible, do not brake suddenly, but rather
moderately at first so that the trailer can acti-
vate its brakes. Then increase the forceont he
brake pedal.
RIf the automatic transmission repeatedly
shifts between gears when driving on inclines,
restrict the shift range. Select shift range 4,3,
2 or 1.
Drivin ginal ow gear and at alow speed
reduces the risk of damaging the engine.
RWhen driving on adownhill 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 instal-
led, the trailer brakes.
RIf the coolant temperature increases dramat-
ically while the air-conditionin gsystem is
switched on, switch off the air-conditioning
system.
Coolant heat can also be dissipated by
switchin gthe airflow and the temperature of
the air conditioning to the maximum level.
Open the windows if necessary.
RWhen overtaking, pay particular attention to
the extended length of your vehicle/trailer
combination.
Due to the length of your vehicle/trailer com- bination you need an additional distance
before you can return to your original lane.
Uncoupling atrailer
GWARNING
If you uncouple atrailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is arisk of injury.
Do not uncouple atrailer if the overrun brake
is engaged.
!Do not disconnect atrailer with an engaged
overrun brake. Otherwise, your vehicle could
be damaged by the rebounding of the overrun
brake.
XMake sure that the selector lever of the auto-
matic transmission is in position P.
XEngage the vehicle's parking brake.
XClose all doors.
XApply the parking brake of the trailer.
XIn addition, secure the trailer against rolling
away withawheel chock or similar object.
XRemove the trailer cable and safety chains
and decouple the trailer.
Permissible trailer loads and trailer
drawbar noseweights
Weight information
!For vehicles with apermissible gross vehicle
weight of 6724 lbs (3050 kg), the permissible gross combination weight is less than the sum
of the permissible gross vehicle weight plus
the permissible trailer load. Exceeding the
permitted gross combination weight could
damage the powertrain ,transmission or
trailer tow hitch.
If either the vehicle or the trailer is fully laden,
the permitted gross vehicle weight or the per- mitted trailer load values are reduced accord-
ingly. In this case, you may only partially load
the trailer or the vehicle.
The gross trailer weight (GTW) is calculated by
adding the weight of the trailer to the weight of
the load and equipment. The permissible gross
trailer weight is 5000 lbs (2268 kg).
The maximum noseweight of the trailer drawbar
on the ball coupling is 500 lbs (227 kg). The
actual noseweight may not exceed the value
given on the identification plates of the trailer
tow hitch or the trailer. If the values vary, the
lowest value alwaysa pplies.
The gross combination weight rating (GCWR) is
calculated by adding the gross weight of the
trailer to the gross vehicle weight including a
166Towing atrailer
