Warning
Unsuitable wheel studs such as single-sec-
tion wheel studs may loosen or come off. The

is a risk of accident. Use only two-section
wheel studs that are recommended by the
manufacturer of the vehicle for the respective
wheel type.
Mount one emergency wheel only, as required.
1. Unscrew the lug bolts.
2. Remove the wheel.
3. Put the new wheel or emergency wheel on

crosswise pattern until hand-tight.
When non-original light-alloy wheels of the
vehicle manufacturer are mounted, the ac-
companying lug bolts may have to be used
as well.
