WARNING■If the wheel has to be changed on a slope, first of all block the opposite
wheel with a stone or similar object to prevent the vehicle from unexpect-
edly rolling away.■
Secure the base plate of the lifting jack with suitable means to prevent
possible moving. A soft and slippery ground under the base plate may move
the lifting jack, causing the vehicle to fall down. It is therefore always nec-
essary to place the lifting jack on a solid surface or use a wide and stable
base. If the surface is smooth, such as on cobbled stones, tiled floor, etc.,
use a non-slip base (e.g. a rubber foot mat).
■
Only attach the lifting jack to the attachment points provided for this pur-
pose.
■
Always raise the vehicle with the doors closed.
■
Never position any body parts, such as arms or legs under the vehicle,
while the vehicle is raised with a lifting jack.
■
When the vehicle is raised, never start the engine.
CAUTION
It is important to ensure that the jack is correctly attached to the web of the
lower fork leg - risk of damage to the vehicle.
Remove the wheel / fix
When changing a wheel, the following instructions must be followed.
›
Remove the full wheel trim or the caps of the wheel bolts.
›
First of all slacken the anti-theft wheel bolt and then the other wheel bolts.
›
Jack up the vehicle until the wheel that needs changing is clear of the
ground.
›
Unscrew the wheel bolts and place them on a clean surface (cloth, paper,
etc.).
›
Remove the wheel carefully.
›
Attach the wheel and slightly screw on the wheel bolts.
›
Lower the vehicle.
›
Tighten the wheel bolts opposite each other using the wheel wrench (alter-
nating crosswise). Tighten the anti-theft wheel bolt last.
›
Replace the wheel trim or the caps.
When fitting unidirectional tyres, ensure that the direction of rotation is cor-
rect » page 178 .
All bolts must be clean and must turn easily.
If it is established when changing a wheel that the wheel bolts are corroded and difficult to move, then these must be replaced.
Under no circumstances grease or oil the wheel bolts.WARNINGUndo the wheel bolts only a little (about one turn) as long as the vehicle
has not yet been jacked up. Otherwise the wheel could become loose and
fall off.
Follow-up tasks
After changing the wheel, the following work must be carried out.
›
Stow the replaced wheel in the wheel well and secure it with a special nut.
›
Stow the tool kit in the space provided and secure using the band.
›
Check the tyre pressure on the fitted 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, save tyre pressure values » page 141.
Replace the damaged wheel or consult a specialist garage about repair op-
tions.
The prescribed tightening torque of the wheel bolts is 120 Nm.
WARNING■
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.■
Drive cautiously and only at a moderate speed until the tightening torque
has been checked.
