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 permissible trailer drawbar
noseweight on the ball coupling is 500 lbs
(227 kg) or 750 lbs (340 kg). The actual 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.
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 319).
The basic values approved by the manufac-
turer can also be found in the "Technical data"
section (Y page 332). 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- 178
