WARNING (Continued)
If the wheel bolts are tightened to a too low tightening torque, the rim
■
can come loose when the car is moving. 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.
In case of incorrect treatment of the wheel bolts, the wheel can loosen
■
when the car is moving.
Note
The national legal requirements must be observed when changing a wheel.

Tighten the opposite wheel bolts alternately (cross-wise) with the wheel
wrench. Tighten the anti-theft wheel bolt last.
›
Replace the wheel trim or the caps.
WARNING
If it is established when changing a wheel that the wheel bolts are corro-
■
ded and difficult to move, then these must be replaced.
When fitting unidirectional tyres, ensure that the direction of rotation is
■
correct » page 156.
Follow-up work

Read and observe on page 166 first.
After changing the wheel, the following work must be carried out.
›
Stow and attach the replaced wheel in the spare wheel well using a special
screw » page 159, Spare and temporary spare wheel.
›
Stow the tool kit in the space provided and secure using the strap.
›
Check the tyre pressure on the installed spare wheel as soon as possible.
›
Have the tightening torque of the wheel bolts checked with a torque
wrench as soon as possible.
After changing the wheel, the tyre pressure should be adjusted. In vehicles
with tyre pressure monitoring, tyre pressure values are to be stor-
ed » page 125.
Replace the damaged wheel or consult a specialist garage about repair op-
tions.
WARNING
Drive cautiously and only at a moderate speed until the tightening torque
has been checked.
