WARNING
Notes for vehicle lifting
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.
Never start the engine when the vehicle is raised – risk of injury.

WARNING
Information on the wheel bolts
The wheel bolts must be clean and must turn easily. Never treat them
■
with grease or oil.
The prescribed tightening torque of the wheel bolts for steel and light al-
■
loy wheels is 120 Nm.
If the wheel bolts are tightened to a too low tightening torque, the rims
■
could come loose when the car is moving – risk of accident! A tightening
torque which is too high can damage the bolts and threads and this can re-
sult in permanent deformation of the contact surfaces on the rims.
In case of incorrect treatment of the wheel bolts, the wheel can loosen
■
when the car is moving – risk of accident!
Note
The national legal requirements must be observed when changing a wheel.

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 spare wheel and slightly screw on the wheel bolts.
›
Lower the vehicle.
›
Alternately tighten wheel bolts opposite (diagonally) with the wheel wrench.
Tighten the anti-theft wheel bolt last
›
Replace the wheel trim or the caps.
Note
All bolts must be clean and must turn easily.
■
Under no circumstances grease or oil the wheel bolts!
