– Tighten the wheel bolts firmly, alternately and diagonally using the wrench* (cross-
wise) page 171.
– 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, ensu re that the tyres rotate in the correct
direction page 160.
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. Steel and light alloy wh eels must be tightened to a tightening
torque of 120 Nm .
– Have the defective tyre repaired as soon as possible.
WARNING
It is necessary to observe the guidelines given on page 162, “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 diffi-
cult 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 tightening
torque can be checked.
Full wheel trim*Pulling off– Hook the clamp found in the vehicle tool ki t into the reinforced edge of the full
wheel trim.
– Push the wheel wrench* through the clamp, support the wheel wrench at the tyre and pull off the wheel trim fig. 160 .Installing– First press the full wheel trim onto the wheel at the valve opening provided. Then
press the full wheel trim into the wheel in such a way that its entire circumference
locks correctly in place.
Caution
Use the pressure of your hand, do not knock on the full wheel trim! Heavy knocks
mainly on the points where the full wheel trim has not been inserted into the wheel,
can result in damage to the guide and centering elements of the full wheel trim.
Check for yourself that the safety wheel bolt * is located in the hole in the area of
the valve before fitting the full wheel trim onto a steel wheel which is attached with a
safety wheel bolt* page 172, “Securing wheels against being stolen*”.
