Checking and refilling levels
Wheel 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 should not use wheel bolts from a different
vehicle, even if it is the same model ⇒ page 189.
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 loos-
en whilst the vehicle is in motion. Risk of accident! If the tightening tor-
que is too high, the wheel bolts and threads can 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 vehicle's han-
dling. 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 pres-
sures 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 reg-
istration 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 217, New tyres and wheels determines the
following speed limits for winter tyres: ⇒
Qmax. 160 km/hSmax. 180 km/hTmax. 190 km/hHmax. 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.

Checking fluid levels
From time to time, the levels of the different fluids in the ve-
hicle must be checked. Never fill with incorrect fluids, other-
wise serious damage to the engine may be caused.
