and ensure that the jack is located in a vertical position at the jacking point

.›
Position the lifting jack below the jacking point with the crank and move it up
until its claw encloses the web » Fig. 176 -
.
›
Continue turning up the jack until the wheel is just about lifted off the
ground.
WARNING■ Choose a flat and firm surface for jacking the vehicle.■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 .
WARNING■
Undo 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.■
All bolts must be clean and must turn easily.
■
If it is established when changing a wheel that the wheel bolts are corro-
ded and difficult to move, then these must be replaced.
■
Under no circumstances grease or oil the wheel bolts!
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 spare 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 125.
Change the damaged wheel or consult a specialist garage about repair possi-
bilities.
WARNINGInformation on the wheel bolts■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 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.
