Description of specifications
Drawbar load
The maximum permitted drawbar load 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 approach-
ing 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 or tandem axle trailers with a
wheelbase of less than 1 metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar load.
WARNING
● For safety reasons, do not exceed the 80 km/h limit. This is also valid
in countries where higher speeds are permitted.
● Never exceed the maximum trailer weights or the drawbar load. 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.
Wheels
Tyre pressure, snow chains, wheel bolts
Tyre 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 should be checked as soon as possible with a torque wrench ⇒
.
The tightening torque for steel and alloy wheels is 120 Nm.
WARNING
● Check the tyre pressure at least once per month. Checking the tyre
pressure 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 Technical Service for information about
appropriate wheel, tyre and snow chain size.
