Wheel bolts
First read and observe the introductory information and safety warn-
ings on page 170.
Wheels and
wheel bolts are matched to each other in terms of design. Each time
you fit other wheels, e.g. light alloy wheels or wheels with winter tyres, you must
therefore also use the matching wheel bolts of the correct length and shape of
spherical cap. This is essential to ensure that the wheels are tightly fitted and
that the brake system operates properly. ÐWinter tyres
First read and observe the introductory information and safety warn-
ings on page 170.
The handling of your vehicle will be significantly improved when driving on wintry
roads if you fit winter tyres. Summer tyres do not offer the same grip on ice, snow
and at temperatures below 7 °C because of their construction (width, rubber
blend, tread pattern). This particularly applies to vehicles which are equipped with
low-profile tyres
or high-speed tyres (code index H or V on wall of tyre).
To achieve the best possible handling properties, winter tyres must be fitted on
all 4 wheels, the minimum tread depth must be 4
mm and tyres must be no older
than 4 years.
Winter tyres of a lower speed category can be used provided that the permissible
maximum speed of these tyres is not exceeded even if the possible maximum
speed of the vehicle is higher. For the sake of the environment
Fit the summer tyres on again in good time as they provide better handling prop-
erties, a shorter braking distance, less tyre noise, and reduced tyre wear on roads
which are free of snow and ice as well as at temperatures above 7
°C. The fuel
consumption is also lower. ÐSnow chains
First read and observe the introductory information and safety warn-
ings on page 170.ä
ä
ä Snow chains must only be mounted on the front wheels.
When driving on wintry roads, snow chains improve not only traction, but also the
braking performance.
For technical reasons, it is only permissible to fit snow chains with the following
wheel/tyre combinations.
Wheel size Depth (D)Tyre size
6J x 15 a)
47 mm 195/65
6.5J x 15 a)
50 mm 195/65
6J x 16 a)
50 mm 205/55
6J x 17 b)
45 mm 205/50 a)
Only fit snow chains with links and locks not larger than 15 mm.
b) Only fit snow chains with links and locks not larger than 9 mm.
Remove the full wheel trims before installing the snow chains.
Observe the national legal regulations relating to the use of snow chains and the
maximum vehicle speed with snow chains. CAUTION
The chains must be removed when driving on roads which are free of snow. They
adversely affect the handling of your vehicle, damage the tyres and are rapidly
destroyed. Ð176
