Jack up the vehicle» page 276 until the wheel that needs changing is clear of
the ground.
›
Unscrew the wheel bolts and place them on a clean surface (cloth, paper,
etc.).
›
Remove the wheel carefully.
›
Attach the spare wheel and slightly screw on the wheel bolts.
›
Lower the vehicle.
›
Tighten the wheel bolts opposite each other using the wheel wrench (“alter-
nating crosswise”)» page 276.
›
Replace the wheel trim » page 275and the caps » page 275.
When fitting a wheel with unidirectional tyres, ensure that the direction of ro-
tation is correct » page 268.
All bolts must be clean and must turn easily. If the screws are corroded and
difficult to move, then these must be replaced.
WARNING
■
Undo the wheel bolts just a little (about one turn) while the vehicle is not
jacked up. Otherwise, the wheel could come off and fall down – there is a
risk of injury.
■
Under no circumstances grease or oil the wheel bolts - risk of accident!
Subsequent steps
After changing the wheel, the following work must be carried out.
›
Place the replaced wheel in the trough under the flooring of the luggage
compartment and secure with a locking screw (insert the support base for
the luggage floor back into the screw).
›
Stow the vehicle tool kit in the space provided.
›
Check and, if necessary, adjust the tyre pressure on the assembled wheel,
and, for vehicle with tyre pressure monitoring, save the tyre pressure values
in the system » page 245.
›
Have the tightening torque of the wheel bolts checked with a torque wrench
as soon as possible. The prescribed tightening torque is 140 Nm.
Replace the damaged tyre. It is not recommended to repair the tyre.
WARNING
A tightening torque which is too high can damage the bolts and threads
and this can result in permanent deformation of the contact surfaces on
the rim. Too low tightening torque, the wheels may fall off while driving -
risk of an accident. Therefore, drive cautiously and only at a moderate
speed until the tightening torque has been checked.
