This enables you to gain experience and get

Driving and parking
Z
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
Driving and parking
driver'sweight of approximately 150 lbs (68 kg).
The permissible Gross Combination Weight Rat-
ing is vehicle-specific and depends on the equip-
ment level.
When driving with atrailer, you should not
exceed the permitted Gross Combination
Weight Rating (GCWR).
The permissible values, which must not be
exceeded, can be found in your vehicle docu-
ment sand on the trailer tow hitc htype plates for
the trailer and the vehicle (
Ypage 294). The
basic values approved by the manufacturer can
also be found in the "Technical data" section
(
Ypage 305). If the values vary, the lowest
value always applies.
Loading atrailer
!Utiliz ethe maximum permissible nose-
weight as fully as possible. Do not allow the
weight to fall below the minimum permissible
noseweight ,otherwise the trailer may come
loose.
RThe load must be distributed over the vehicle
and the trailer so as not to exceed either the
maximum permissible values for the gross
vehicle weight ratin g(GVWR) and gross trailer
weight (GTW), the gross combination weight
ratin g(GCWR), nor the maximum permissible
gross axle weight ratin g(GAWR) and trailer
drawbar noseweight ratin gofyour vehicle.
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the rear axle load. This will pre-
vent you from exceeding the permissible
gross axle weight (GAWR).
RAdd the drawbar noseweight on the ball cou-
pling (TWR) to the vehicle payload. This will
ensure that you do not exceed the permissi-
ble gross vehicle weight ratin g(GVWR).
Checking the vehicle and trailer weight
RMake sure the weights of the towing vehicle
and the trailer comply with the maximum per-
missible values. Have the vehicle/trailer com-
bination weighed on acalibrated weigh-
bridge. The vehicle/trailer combination con-
sists of the towing vehicle includin gthe driver,
passenger sand load, as well as the loaded
trailer.
RCheck the maximum permissible gross axle
weight ratin gofthe fronta nd rear axles
(GAWR), the gross trailer weight (GTW), the gross combination weight ratin
g(GCWR) and
the noseweight of the trailer drawbar (TWR).
Trailer power supply
!
Incorrectw iring of the connector plug could,
under certain circumstances, cause malfunc-
tion sint he vehicle's other electronic sys-
tems .Wet herefore recommend having the
connector plug wired at aqualified specialist
workshop.
!You can connec taccessories with amaxi-
mum power consumption of 240 Wtothe
permanen tpower supply.
You must not charge atrailer battery using the
power supply.
Your vehicle may be equipped with various elec-
trical installations for trailer towing .Depending
on your trailer, you may need an adapter to con-
nec tthe electrical system of the trailer with that
of the vehicle.
The trailer socket of your vehicle is equipped at
the factory with apermanen tpower supply.
The permanen tpower supply is on the trailer
socket pin assignmen t4.
Note that the permanen tpower supply of the
trailer is not switched off when the on-board
voltage is low. This can completely discharge
the starter battery of your vehicle.
Further information on the electrical equipment currently installed on your vehicle and on instal-
ling trailer electrics can be obtained at any quali-
fied specialist workshop.

Changing wheels
Rotating the wheels
GWARNING
Interchanging the front and rear wheels may
severelyi mpair the driving characteristics if
the wheels or tires have different dimensions. The whee lbrakes or suspension components
may als obedamaged. There is arisk of acci-
dent.
Rotate front and rear wheels only if the wheels and tires are of the same dimensions.
!On vehicles equippedw ithatire pressure
monitor, electronic components are located
in the wheel.
Tire-mounting tools should not be used near
the valve .This could damage the electronic
components.
Only have tires changed at aqualified spe-
cialist workshop.
Always observe the instructions and safety
notes under "Mounting awheel" (
Ypage 287).
The wea rpatterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before aclear wea rpattern
has formed on the tires. Front tires typically
wea rmore on the shoulders and the rear tires in
the center.
If you rvehicle's tire configuration allows, you
can rotate the wheels according to the intervals
in the tire manufacturer's warranty book in your
vehicled ocuments. If no warranty book is avail-
able, the tires should be rotated every 3,000 to
6,000 mile s(5,000 to 10,000 km) or earlier if
tire wea rrequires. Do not change the direction
of rotation.
Clean the contact surfaces of the whee land the

ted. Avoid oily or greas ycleaning agents.
Check the tire pressure and reactivate the tire
pressure monitor if necessary.
Directio nofrotation
Tires with aspecified directio nofrotation have
additional benefits, e.g. if there is arisk of hydro-
planing. You wil lonly gai nthese benefits if the
correct directio nofrotation is observed.
An arrow on the sidewal lofthe tire indicates its
correct directio nofrotation.
You may mount aspare whee lagainst the direc-
tion of rotation. Observe the time restriction on
use as wel lasthe speed limitation specified on
the spare wheel.
Storing wheels
Store wheels that are not being used in acool,
dry and preferably dark place. Protect the tires
from contact with oil, greas eand fuel.
