– Tighten the wheel bolts firmly, alternately and diagonally using the
wheel wrench ⇒page 209.
– Mount the full wheel trim/wheel trim cap or the caps.
Note•
All bolts must be clean and must turn easily.
•
You must never grease or oil the wheel bolts!
•
When fitting on unidirectional tyres, ensure that the tyres rotate in the correct
direction ⇒page 198.
Subsequent stepsAfter changing the wheel, you must perform the following steps.
– Stow and attach the replaced wheel in the spare wheel well.
– Stow the vehicle tool kit in the space provided.
–Check the tyre pressure on the spare wheel just mounted as soon as
possible.
– Have the tightening torque of the wheel bolts checked with a torque
wrench as soon as possible. The tightening torque for steel and light
alloy wheels must be 120 Nm.
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on ⇒page 200, “New tyres
and wheels” if the vehicle is subsequently fitted with tyres which are
different to those it was fitted with at the works.
Note
•
If you find, when changing the wheel, that the wheel bolts are corroded and
difficult to turn, the bolts must be replaced before checking the tightening torque.
•
Drive cautiously and only at a moderate speed to a workshop where the tight-
ening torque can be checked.
Full wheel trim*Pulling off
– Hook the clamp found in the vehicle tool kit into the reinforced edge
of the full wheel trim.
