exceeded:
R the permissible trailer drawba rnoseweight
R the permissible trailer load
R the permissible rea raxle load of the towing
vehicle
R the maximum permissible gros svehicle
weight of both the towing vehicle and the
trailer
The applicable permissible values, which
must not be exceeded, can be found:
R in the vehicle documents
R on the identification plates of the trailer tow
hitch, the trailer and the vehicle
If the values differ, the lowest value applies.
You will fin dthe values approved by the man-

and those for the towing vehicle under "Tech-
nical data "(Ypage 433).
When towing atrailer, your vehicle's handling
characteristics wil lbedifferent in comparison
to when drivin gwithout atrailer.
Th ev ehicle/ trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbin gcapability
R has an increased braking distance
R is affected more by stron gcrosswinds
R demand smore sensitive steering
R has alarger turnin gcircle
This could impair the handling charac teris-
tics. Adapt your styl eofdriving accordingly.
Maintain asafe distance. Drive carefully.
When towing atrailer, alw aysa djust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis-
sible speed for your vehicle/trailer combina-
tion.
General notes !
Use adrawbar noseweigh tasc lose as
possible to the maximum permissible nose-
weight. Do not use anoseweight of less than 50kg, otherwise the trailer ma

Not ethat the payload and the rea raxle load
are reduce dbythe actual payload.
i Chec kthe tyr epressures when towin ga
trailer. You will find the values in the tyre
pressure table in the fuel filler flap of the
vehicle (Y page 399).
You will find installation dimensions and loads
in the "Technical data" section
(Y page 432).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 140 kg.
However, the actual noseweight must not
exceed the value given on the trailer tow hitch
or trailer identification plates .The lowest
weight applies.
Please not ethat when towing atrailer, PARK-

Driving tips i
Observ ethe information on ESP ®
trailer
stabilisation (Y page 67)and on pulling
away with atrailer. (Y page 162).
Vehicle swith the ON&OFFROAD pack-
age: select the trailer program (Y page 250)
with the off- road program selector wheel in
the centre console.
The maximum permissible spee dfor vehicle/
trailer combina tions depends on the type of
trailer .Befor ebeginning the journey, check
the trailer's document stosee what the max-
imu mpermitted speed is. Observ ethe legally
prescribed maximum speed in the relevant
country.
For cer tain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing atrailer. See "Technica ldata" to
find out whethe rthis applies to your vehicle
(Y page 433). If you utilise any of the added
maximum rea raxle load whe ntowing atrailer,
th ev ehicle/ trailer combination may not
