General notes on the technical data
288Towing a trailerTrailer weightsTrailer weights
The trailer weights and drawbar loads approved are selected in intensive
trials according to precisely defined criteria. The approved trailer weights are
valid for vehicles in the EU for maximum speeds of 80 km/h (in certain
circumstances up to 100 km/h). The figures may be different in other coun-
tries. All data in the official vehicle documents take precedence over these
data ⇒ .
Drawbar load
The maximum permitted weight exerted by the trailer drawbar on the ball joint
of the towing bracket must not exceed 75 kg.
In the interest of road safety, we recommend that you always tow
approaching the maximum drawbar load. The response of the trailer on the
road will be poor if the drawbar load is too small.
If the maximum permissible drawbar load cannot be met (e.g. with small,
empty and light-weight single axle trailers o r ta n d e m a x l e t r a i l e r s wi t h a n a x le
base of less than 1 metre), at least 4% of the actual trailer weight is a legal
stipulation for a drawbar load.
WARNING
•For safet y reas ons , d o not excee d the 8 0 k m/h limit . Th is is als o valid in
countries where higher speeds are permitted.•Never exceed the maximum trailer weights or the draw bar loading. If
the permissible axle load or the permissible total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.
WheelsTyre pressure, snow chains, wheel boltsTyre pressures
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given there are for cold tyres. The slightly
raised pressures of warm tyres must not be reduced. ⇒
Snow chains
Snow chains may be fitted only to the front wheels.
Consult the chapter “wheels” of this manual.
Wheel bolts
After the wheels have been changed, the tightening torque of the wheel bolts
s ho uld b e che cke d as s o on as p ossible wit h a to rqu e w re nch ⇒ . The tight-
ening torque for steel and alloy wheels is 120 Nm.
WARNING
•Check the tyre pressure at least once per month. Checking tyre pressure
value is very important. If the tyre pressure is too high or too low, there is
an increased danger of accidents, particularly at high speeds.•If the torque of the wheel bolts is too low, they could loosen while the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads can be damaged.Note
We recommend that you ask your Authorised Service Centre for information
about appropriate wheel, tyre and snow chain size.

Te c h n i c a l D a t aChecking fluid levelsFrom time to time, the levels of the different fluids in the
vehicle must be checked. Never fill with incorrect fluids,
otherwise serious damage to the engine may be caused.Fig. 233 Diagram for the location of the various elements
