inclines, restrict the shift range. Select shift
range 4,3, 2or 1.
Driving in a low gear and at a low speed
reduces the risk of damaging the engine.
R When driving on a downhill 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
installed, the trailer brakes.
R If the coolant temperature increases dra-
matically while the air-conditioning system
is switched on, switch off the air-condition-
ing system.
Coolant heat can also be dissipated by
switching the airflow and the temperature
of the heater/air conditioning to the maxi-
mum level. Open the windows if necessary.
R When overtaking, pay particular attention
to the extended length of your vehicle/
trailer combination.
Due to the length of your vehicle/trailer
combination you need an additional dis-
tance before you can return to your original
lane. Uncoupling a trailer
G
WARNING
If you uncouple a trailer with the overrun
brake engaged, you could trap your hand
between the vehicle and the trailer drawbar.
There is a risk of injury.
Do not uncouple a trailer if the overrun brake is engaged.
! Do not disconnect a trailer with an
engaged overrun brake. Otherwise, your
vehicle could be damaged by the rebound- ing of the overrun brake.
X Make sure the selector lever of the auto-
matic transmission is in position P.
X Apply the parking brake of the vehicle.
X Close all doors. X
Apply the parking brake of the trailer.
X In addition, secure the trailer against rolling
away with a wheel chock or similar object.
X Remove the trailer cable and safety chains
and decouple the trailer. Permissible trailer loads and trailer
drawbar noseweights
Weight information !
On vehicles with a permissible gross vehi-
cle weight of 11030 lbs (5003 kg), the per- missible gross combination weight is less
than the total of the permissible gross vehi-
cle weight and the permissible trailer load.
Exceeding the permissible gross combina-
tion weight can lead to damage to the driv-
etrain, to the transmission or to the trailer
tow hitch.
If the vehicle or the trailer is fully laden, the relevant value for the permissible gross
vehicle weight or the permissible trailer
load is therefore lower. In this case, the
trailer or the vehicle may only be partially
loaded.
The gross trailer weight (GTW) is calculated by adding the weight of the trailer to the weight
of the load and equipment.
The maximum gross vehicle weight is vehicle-specific and equipment-dependent: 5,000 lbs
(2,268 kg) or 7,500 lbs (3,402 kg).
The maximum perm issible trailer drawbar
noseweight on the ball coupling is 500 lbs
(227 kg) or 750 lbs (340 kg). Theactual nose-
weight 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 always applies.
The gross combination weight rating (GCWR)is calculated by adding the gross weight of the
trailer to the gross vehicle weight including a
driver's weight of approximately 150 lbs
(68 kg). The permissible Gross Combination
Weight Rating is vehicle-specific and depends
on the equipment level. Towing a trailer
177Driving and parking Z

When driving with a trailer, 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-
ments and on the trailer tow hitch type plates
for the trailer and the vehicle (Y page 316).
The basic values approved by the manufac-
turer can also be found in the "Technical data" section (Y page 328). If the values vary, the
lowest value always applies.
Loading a trailer !
Utilize the maximum permissible nose-
weight as fully as possible. Do not allow the
weight to fall below the minimum permis-
sible noseweight, otherwise the trailer may
come loose.
R You must distribute the load on the vehicle
and trailer so that the permitted maximum
values for the gross vehicle weight (GVWR), gross trailer weight (GTW) and gross com-
bined weight (GCWR) as well as permitted
gross axle loads (GAWR) and noseweight
(TWR) of your vehicle are not exceeded.
R Add the drawbar noseweight on the ball
coupling (TWR) to the rear axle load. This
will prevent you from exceeding the per-
missible gross axle weight (GAWR).
R Add the drawbar noseweight on the ball
coupling (TWR) to the vehicle payload. This
will prevent you from exceeding the per-
missible gross vehicle weight (GVWR).
Checking the vehicle and trailer weight R
Make sure the weights of the towing vehicle
and the trailer comply with the maximum
permissible values. Have the vehicle/
trailer combination weighed on a calibrated weighbridge. The vehicle/trailer combina-
tion consists of the towing vehicle including
the driver, passengers and load, as well as
the loaded trailer.
R Check the maximum permissible gross axle
weight rating of the front and rear axles (GAWR), the gross trailer weight (GTW), the
gross combination weight rating (GCWR)
and the noseweight of the trailer drawbar
(TWR). Trailer power supply
! Incorrect wiring of the connector plug
could, under certain circumstances, cause
malfunctions in the vehicle's other elec-
tronic systems. We therefore recommend
having the connector plug wired at a quali-
fied specialist workshop.
! You can connect accessories with a max-
imum power consumption of 240 W to the
permanent power supply.
You must not charge a trailer battery using
the power supply.
Your vehicle may be equipped with various
electrical installations for trailer towing.
Depending on your trailer, you may need an
adapter to connect the electrical system of
the trailer with that of the vehicle.
The trailer socket of your vehicle is equipped at the factory with a permanent power supply.
The permanent power supply is on the trailer
socket pin assignment 4.
Note that the permanent power 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.
The turn signals on the trailer are only guar-
anteed to function when incandescent bulbs
are used.
Further information on the electrical equip-
ment currently installed on your vehicle and
on installing trailer electrics can be obtained
at any qualified specialist workshop. 178

cle (Y page 312).
Information about installing a wheel can be
found in the "Wheel change" section
(Y page 306).
When you replace a tire, we recommend that
you also replace the tire valve. Please observe
the safety-relevant information on tire valve
(Y page 290). Changing wheels
Rotating the wheels
G
WARNING
Interchanging the front and rear wheels may
severely impair the driving characteristics if
the wheels or tires have different dimensions. The wheel brakes or suspension components
may also be damaged. There is a risk of acci-
dent. Rotate front and rear wheels only if the wheels
and tires are of the same dimensions.
! On vehicles equipped with a tire pressure
monitor, electronic components are loca-
ted in the wheel.
Tire-mounting tools should not be used
near the valve. This could damage the elec- tronic components.
Only have tires changed at a qualified spe-cialist workshop.
Always observe the instructions and safety
notes in the "Mounting a wheel" section
(Y page 306).
The wear patterns on the front and rear tires
differ, depending on the operating conditions. Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires in the center.
If your vehicle's tire configuration allows, you can rotate the wheels according to the inter-
vals in the tire manufacturer's warranty book
in your vehicle documents. If no warranty
book is available, the tires should be rotated
every 3,000 to 6,000 miles (5,000 to
10,000 km), or earlier if tire wear requires. Do
not change the direction of rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated.
Check the tire pressure and reactivate the tire pressure monitor if necessary. Diagram showing tire rotation for single and dual
