Technical specifications
are for cold tyres. The slightly raised pres-
sures of warm tyres must not be reduced.

The pressure for winter tyres is 0.2 bar
(2.9 psi / 20 kPa) higher than that of summer
tyres.
Wheel bolts
WARNING
For safety reasons, you should not drive
at speeds above 80 km/h (50 mph) when
towing a trailer. This also applies in coun-
tries where higher speeds are permitted.
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.
●
Never exceed the maximum trailer
weights or the drawbar load. If the permis-
sible axle load or the permissible total
weight is exceeded, the driving character-
istics of the vehicle may change, leading to
accidents, injuries and damage to the vehi-
cle.
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 ac-
cidents - particularly at high speeds.
Snow chains
●
Snow chains may be fitted only to the front
wheels, and only for the following tyres:
195/65 R15
205/55 R16 Chains with links of maximum 15 mm
205/50 R17
●
If the tightening torque of the wheel bolts
is too low, they could loosen while the vehi-
cle is in motion. Risk of accident! If the
tightening torque is too high, the wheel
bolts and threads can be damaged.
