Wheel boltsFirst read and observe the introductory information and safety warn-ings
on page 172.
Wheels and wheel bolts are matched to each other in terms of design. Each time
you fit other wheels rims, e.g. light alloy wheel rims or wheels with winter tyres,
you must also use the matching wheel bolts with the correct length and dome
shape. Correct fastening of the wheels depends on this.

Winter tyres
First read and observe the introductory information given on page 178.
Fitting winter tyres will significantly improve the handling of your vehicle when
driving in wintry road conditions. Summer tyres have less grip on ice, snow and at
temperatures below 7 °C. This is especially true of wide tyres or high-speed tyres .
In order to achieve the best possible handling properties, winter tyres must be fit-
ted 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.
The speed limit for winter tyres can be set in the MAXI DOT display in the Winter
tyres menu item » page 18.
For the sake of the environmentRe-fit the summer tyres at an appropriate time as they provide better handling
properties, 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.
Snow chains
First read and observe the introductory information given on page 178.
When driving in wintry road conditions, snow chains improve not only traction,
but also the braking performance.
Snow chains must only be mounted on the front wheels.
For technical reasons, it is only permissible to fit snow chains with the following wheel/tyre combinations.
Wheel sizeDepth (D)Tyre size5J x 1435 mm175/706J x 1437 mm185/656J x 1543 mm185/55
Only fit snow chains with links and locks not larger than 12 mm.
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 rap-
idly destroyed.■
Remove the full wheel trims before installing the snow chains.
