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.
