Changing a wheelAlways change a wheel on a level surface as far as possible.
– Take off the full wheel trim* page 218 or the caps page 219.
– In the case of light alloy wheels remove the wheel trim cap page 219.
– First of all slacken the safety wheel bolt * and afterwards the other wheel bolts page 219.
– Jack up the vehicle until the wheel to be changed is clear of the ground page 220.
– Unscrew the wheel bolts and place them on a clean surface (cloth, paper etc.).
– Take off the wheel.
– Fit on the spare wheel and ti ghten the wheel bolts slightly.
–Lower the car.
– Tighten the wheel bolts firmly, alternately and diagonally using the wheel wrench (crosswise) and last the safety wheel bolt* page 219.
– 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 208.
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 wheels must be tightened to a tightening
torque of 120 Nm.
– Change the damaged wheel or consult a sp ecialist garage about possibilities for
getting repairs done.
WARNING
It is necessary to observe the guidelines given on page 210 if the vehicle is
subsequently fitted with tyres which are di fferent 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.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.
