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 are only permitted on the front wheels and only for tyres 155/80 R13; 165/70 R14 and 185/80 R14. Snow chains must have fine-pitch links which do not protrude more than 15 mm, including tension device. Remaining tyres can be fitted with chains no thicker than 9 mm.
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. Correct 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 whilst the vehicle is in motion. Risk of accident! If the tightening torque is too high, the wheel bolts and threads could be damaged.

Note
We recommend that you ask your Authorised Service Centre for information about appropriate wheel, tyre and snow chain size.
