Tightening torques
Caution
If the vehicle is equipped with alloy
wheels, tighten the wheel bolts
manually at least for the first five
turns.
There are two different types of
wheels with two different bolts and tightening torques.
Tightening torque for alloy wheels is
100 Nm.
Tightening torque for steel wheels is
115 Nm.
Use the correct wheel bolts for the respective wheels.
Jacking positions The jacking positions shown refer to
the use of lifting arms and accessory
jacks used for changing winter /
summer tyres.

9Warning
Ensure to use always the correct
wheel bolts if changing the
wheels. When installing the spare
wheel, the bolts for alloy wheels can also be used.
● Note that the spare wheel is secured by the conical contact ofeach bolt if the wheel bolts for the
alloy wheels are used. In this
case, the washers do not come
into contact with the spare wheel.
1. Disengage wheel bolt caps with the wheel bolt cover remover.

Steel wheels with cover: Pull off
the wheel cover.
Alloy wheels: Disengage wheel
bolt caps with the wheel bolt cover remover.
2. Fold out the wheel wrench and install ensuring that it locates
securely and loosen each wheel
nut by half a turn.
The wheels might be protected by
locking wheel nuts. To loosen
these specific nuts first attach the
adapter onto the head of the nut
before installing the wheel
wrench. The adapter is located in
the tool box. 3 228

bolts can also be used for the steel spare wheel. In this case, the
spare wheel is secured by the
conical contact of each bolt.
10. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
11. Stow the replaced wheel 3 238,
the vehicle tools 3 228 and the
adapter for the locking wheel nuts.
