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. Use a non-slip base (e.g. a rubber foot mat) if the surface is smooth,
such as cobbled stones, tiled floor, etc.
■
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
Make sure that the jack is attached correctly to the web on the lower sil, oth-
erwise there is a 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 opposite wheel bolts alternately (cross-wise) with the wheel
wrench. 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 163 .
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 should you grease or oil the wheel bolts!WARNINGUndo the wheel bolts only a little (about one turn) until the vehicle has
been jacked up. Otherwise the wheel could become loose and fall off.
Subsequent steps
After changing the wheel, the following work should be carried out.
›
Stow the replaced wheel in the wheel well and secure it with a special screw.
›
Stow the tool kit in the space provided and secure using the strap.
›
Check the tyre pressure on the installed 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 126.
Change the damaged wheel or consult a specialist garage about repair possi-
bilities.
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.
