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 192
.
Subsequent steps After changing the wheel, you must perform the following steps.
–
Stow and attach the replaced wheel in the spare wheel well using a special
screw ⇒ fig. 163 .
– 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 tight-
ening torque of 120 Nm.
– Change the damaged wheel or consult a specialist garage about possibilities
for getting repairs done. WARNING
It is necessary to observe the guidelines given on ⇒
page 194 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. –
Push the wheel key through the clamp, support the wheel key at the tyre and
pull off the wheel trim.
Install
– 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 cir-
cumference 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 centring 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 203, Securing wheels against being stolen.
Wheel bolts with caps Fig. 164 Removing the cap.
Pulling off
– Push the plastic clip sufficiently far onto the cap until the inner catches of the
clip are positioned at the collar of the cap and detach the cap ⇒ fig. 164 .
Install
– Push the caps fully onto the wheel bolts.
The caps are located in the well of the luggage compartment. 201
