Towing a trailer
Notes on trailer towing
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
GWARNING
If you use a ball coupling that is not approved
for your vehicle, it may cause excessive strain
on the trailer tow hitch. This can cause dam-
age to the vehicle and the trailer may come
loose during the journey. The handling may be
impaired and the rear axle may be overloaded.
This may lead to an accident involving serious
or even fatal injury.
Therefore note the following:
ROnly install a ball coupling that is approved
for your vehicle.
RBefore the journey, make sure that the ball
coupling is correctly installed and secured.
To do this, observe the operating instruc-
tions of the ball coupling manufacturer.
RDo not make any modifications to the ball
coupling or the trailer tow hitch.
You must observe the operating instructions
of the trailer tow hitch or ball coupling manu-
facturer.
GWARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving and endanger other road users. There is a risk
of an accident and injury.
Install and secure the ball coupling as descri-
bed in the ball coupling manufacturer's instal-
lation instructions. Make sure that the ball
coupling is correctly installed and secured
before every journey.
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
You can attach carrier systems such as bicycle
racks or load-bearing implements on the ball
coupling. The maximum load-bearing capacity
of 165 lb (75 kg) applies when using carrier sys-
tems on the ball coupling.
Always observe the operating instructions pro-
vided by the manufacturers of the trailer cou-
pling and the ball coupling.
Couple and decouple the trailer carefully. When
backing up the towing vehicle, make sure
nobody is standing between the vehicle and the trailer.

Uncoupling a trailer
GWARNING
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 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 with a wheel 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 a permissible 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. If the trailer is installed
with a separate functional braking system, then
the maximum gross trailer weight is 5000 lbs
(2268 kg).
GWARNING
If you tow a trailer without a separate func-
tional braking system and a gross trailer
weight (GTW) of more than 1635 lbs (750 kg),
then the vehicle brake system may overheat.
This increases the braking distance and the
brake system may even fail. There is an
increased risk of accident and injury, possibly
even fatal.
Always use a trailer with a separate functional
braking system when towing a trailer with a
gross trailer weight (GTW) of more than
1635 lbs (750 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 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 Rat-
ing is vehicle-specific and depends on the equip-
ment level.
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 (
Ypage 303). The
basic values approved by the manufacturer can
also be found in the "Technical data" section
(
Ypage 313). 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 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 rating (GVWR) and gross trailer
weight (GTW), the gross combination weight

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the vehi-
cle while driving, you will be distracted from
traffic conditions. You could also lose control
of the vehicle. There is a risk of an accident.
Only operate the equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
GWARNING
If you are driving and reach through the steer- ing wheel to operate the adjustment knob,
you could lose control of the vehicle. There is
a risk of an accident and injury.
Only operate the adjustment knobs when thevehicle is stationary. Do not reach through the
steering wheel when driving.
You must observe the legal requirements for the
country in which you are currently driving when
operating the on-board computer.
GWARNING
If the instrument cluster has failed or mal-
functioned, you may not recognize function
restrictions in systems relevant to safety. The
operating safety of your vehicle may be
impaired. There is a risk of an accident.
Drive on carefully. Have the vehicle checked
at a qualified specialist workshop immedi-
ately.
The on-board computer display only shows mes-
sages and warnings from certain systems. You
should therefore make sure your vehicle is oper-
ating safely at all times. If the operating safety of
your vehicle is impaired, stop the vehicle as
soon as possible, paying attention to road and
traffic conditions. Then consult a qualified spe-
cialist workshop.
The accuracy of the speedometer and odometer
displays is legally prescribed. Determining the
speed is dependent on the wheel size or the
rolling circumference of the wheels. If you
change the wheel size on your vehicle, make
sure it is assigned to the correct wheel size cat-
egory (
Ypage 277). If you change wheel size
category without recoding the control unit, the
speedometer indication will be inaccurate. Driv-
ing safety and driving systems may be impaired
or detect a malfunction and shut down.

the display shows a message when the vehi-
cle reaches the maximum legally permissible speed limit, e.g. at 75 mph (120 km/h).
Tachometer
!
Do not drive in the overrevving range, as this
could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consumption
of your vehicle and harms the environment as
a result of increased emissions.
The red band in the tachometer indicates the
engine's overrevving range.
To protect the engine, the fuel supply is inter-
rupted when the red band is reached.
Outside temperature display
You should pay special attention to road condi-
tions when temperatures are around freezing
point.
Please bear in mind that the outside tempera-
ture display shows the air temperature meas-
ured and not the road temperature.
The display shows the outside temperature in
the header:
