228Wheel bolts
Wheel bolts must be tightened to the correct torque.The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped bolt
heads must be used. This ensures that wheels are fitted securely and that the
brake system functions correctly.
In certain circumstances, you may not use wheel bolts from a different car -
even if it is the same model ⇒page 199.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.•
The wheel bolts must be clean and turn easily. Never apply grease or oil
to them.
•
Use only wheel bolts which belong to the wheel.
•
If the prescribed 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.Caution
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm.
Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyres (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle’s regis-
tration documents. Use only radial winter tyres. All tyre sizes listed in the
vehicle documentation also apply to winter tyres.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒page 226, “New tyres and wheels” determines the
following speed limits : ⇒
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
H max. 210 km/h
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver’s field of view. These
stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 226, “New tyres and wheels”.
