Vehicle tool kit
The vehicle tool kit is housed in a box in the spare wheel or in the compart-
ment for the spare wheel underneath the floor covering in the luggage com-
partment. The box is attached with a strap on the spare wheel.
Depending on the equipment, not all the components listed in the on-board
tool kit have to be contained in it.
Screwdriver
Adapter for anti-theft wheel bolts
Towing eye
Clamps for removing the wheel trims
Depending upon vehicle equipment: Jack with sign / puncture repair kit
Wheel wrench
Extraction pliers for wheel bolt caps
Replacement bulb set
WARNINGThe factory-supplied lifting jack is only intended for your model of vehicle.
Under no circumstances attempt to lift heavier vehicles or other loads.12345678CAUTION■ Screw the jack back into the starting position before storing in the box with
the tool kit.■
Ensure that the vehicle tool kit is safely secured in the boot.
■
Ensure that the box is always secured with the strap.
Note
The declaration of conformity is included with the jack or the log folder.

Anti-theft wheel bolts
169WARNING■ 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 160,
Explanation of the tyre labelling .
WARNINGInformation 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.
166Do-it-yourself
WARNING (Continued)■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 166 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.
›
Engage 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 166 and the spare wheel » page 159 ,
Spare and temporary spare wheel from the boot.
Changing a wheel
Read and observe
on page 166 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.
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.■
When fitting unidirectional tyres, ensure that the direction of rotation is
correct » page 156 .
Follow-up work
Read and observe
on page 166 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
screw » page 159 , Spare and temporary spare wheel .
›
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, tyre pressure values are to be stor-
ed » page 125 .
Replace the damaged wheel or consult a specialist garage about repair op-
tions.
WARNINGDrive cautiously and only at a moderate speed until the tightening torque
has been checked.167Emergency equipment and self-help
