local regulations. This not only applies to your
place of residence, but also to your destination.
In fo rm ation on this can be obtained from the
police and local authorities.

th
e permissible gross vehicle weight plus the per‐
missible trailer load. If either theve hicle or the
trailer is fully laden, the permitted gross vehicle
we ight or the permitted trailer load values are
re duced accordingly. In this case, you may on ly
partially load the trailer or theve hicle.
The gross trailer weight (G TW) is calculated by
adding thewe ight of the trailer tothewe ight of
th e load and equipment. If the trailer is equipped
with a separate braking sy stem, then the maxi‐
mum gross trailer weight is 5000 lbs (2268 kg) or
75 00 lbs (3402 kg).
The maximum permissible trailer dr awbar nose‐
we ight on the ball head is 500 lbs (227 kg) or
75 0 lbs (340 kg). Ho wever,th e actual trailer
dr aw bar nose weight must not exceed theva lue
given on the trailer tow hit chor trailer identifica‐
tion plates. Where theva lues dif fer, th e lo west
va lue alw ays applies.
The permissible gross weight forve hicle-trailer
combinations (GCWR) is calculated byadding the
gross weight of the trailer tothe gross vehicle
we ight including a driver's weight of appr ox‐
imately 150 lbs (68 kg). The maximum permissi‐
ble gross combination weight is vehicle-specific
and equipment-dependent. When driving with a
trailer, you should not exceed the maximum per‐
mitted permissible gross weight forve hicle-trailer
combinations (GCWR).
The permissible values, which must not be excee‐
ded, can be found in your vehicle documents and
on the identification plates of the trailer tow
hitch, the trailer and theve hicle. The values
appr ovedby the manufacturer can also be found
in the "Technical data" section. Where theva lues
dif fer, th e lo west value alw ays applies.
Loading the trailer
Use a dr awbar nose weight that is as close as
possible tothe maximum permissible nose‐
we ight. Do not undershoot the minimum permis‐
sible nose weight. Otherwise, the trailer may
become de tach ed.
R Distribute the load over theve hicle and the
trailer so as not toexceed either the maxi‐
mum permissible values forth e gross vehicle
we ight rating (GVWR) and gross trailer weight
(G TW ),th e permissible gross weight forve hi‐
cle-trailer combinations (GCWR), nor the max‐
imum permissible gross axle weight rating
(GAWR) and trailer dr awbar nose weight (TWR)
of your vehicle.
R Addth ere ar axle load tothe trailer dr awbar
nose weight of the trailer dr awbar on the ball head (TWR). This will ensure
that you do not
ex ceed the permissible gross axle weight rat‐
ing (G AWR).
R Addth eve hicle load tothe trailer dr awbar
nose weight of the trailer dr awbar on the ball
head (TWR). This will ensure that you do not
ex ceed the permissible gross vehicle weight
ra ting (GVWR).
Che cking theve hicle and trailer weight
R Make sure that thewe ights of theto wing
ve hicle and the trailer comply with the maxi‐
mum permissible values. Ha vethe car/t railer
combination weighed on a calibrated weigh‐
ing machine. The car/trailer combination
comprises theto wing vehicle including driver,
passengers and load as well as the laden
trailer.
R Check the maximum permissible gross axle
we ight rating of the front and rear axles
(GAWR), the gross trailer weight (G TW),the
permissible gross weight forve hicle-trailer
combinations (GCWR) and the trailer dr awbar
nose weight rating (TWR). Tr
