Operation Manual

WARNING
■
If you are in flowing traffic, switch on the hazard warning light system
and set up the warning triangle at the prescribed distance! The national le-
gal requirements must be observed.
■
Park the vehicle as far away as possible from the flow of traffic. Park on
as flat and firm a surface as possible.
■
The following instructions must be followed if the vehicle is subsequently
fitted with tyres or rims that differ from the factory fitted ones » page 201,
Explanation of the tyre labelling.
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 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.
■
In case of incorrect treatment of the wheel bolts, the wheel can loosen
when the car is moving.
Note
The national legal requirements must be observed when changing a wheel.
Preliminary work
Read and observe on page 206 first.
Before changing the wheel, the following work must be carried out.
›
Have all the occupants get out. The passengers should not stand on the
road (instead they should remain behind a crash barrier, for instance) while
the wheel is being changed.
›
Switch off the engine.
›
Select the 1st gear or place the selector lever of the automatic transmission
in the P-position.
›
Apply the handbrake firmly.
›
Uncouple a trailer.

›
Remove the vehicle tool kit » page 205and the spare wheel » page 200from
the boot.
Changing a wheel
Read and observe on page 206 first.
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 spare 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 indication is cor-
rect » page 197.
WARNING
If it is established when changing a wheel that the wheel bolts are corro-
ded and difficult to move, then these must be replaced.
Follow-up work
Read and observe on page 206 first.
After changing the wheel, the following work must be carried out.
›
Stow and attach the replaced wheel in the spare wheel well using a special
bolt » page 200.
›
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.
