WARNINGObserve the following instructions for handling the airbag system.■It is prohibited to manipulate individual parts of the airbag system, as this
might result in the airbag being deployed.■
Never install any airbag parts into the vehicle that have been removed from
old cars or have been recycled.
■
Never install damaged airbag parts in the vehicle. The airbags may then not
be deployed properly or even at all in the event of an accident.
■
No modifications of any kind must be made to parts of the airbag system.
WARNING■ A change to the vehicle's wheel suspension, including the use of non-ap-
proved wheels and tire combinations, can alter the functioning of the airbag system - risk of accident and fatal injury!■
Never make any changes to the front bumper or the bodywork.
Washing your car

The best way to protect your vehicle against harmful environmental influences is frequent washing.
How often the vehicle should be washed depends on factors such as: › Frequency of use.
› Parking situation (garage, under trees etc.).
› Season.
› Weather conditions.
› Environmental influences.
The longer insect residues, bird droppings, tree sap, road and industrial dust, tar,
soot particles, road salt and other aggressive deposits remain adhering to the
paintwork of your vehicle, the more detrimental their destructive effect can be.
High temperatures, such as those caused by intensive sun's rays, accentuate this
caustic effect.
It is essential to also thoroughly clean the underside of the vehicle at the end of
the winter.WARNING■ When washing your vehicle in the winter: Water and ice in the braking sys-
tem can affect the braking efficiency – risk of accident!■
Only wash the vehicle when the ignition is switched off – risk of accident!
CAUTION
Do not wash your vehicle in bright sunlight – risk of paint damage.
For the sake of the environment
Only wash the vehicle at washing bays intended for this purpose.
Washing by hand
First read and observe the introductory information and safety warn-
ings
on page 152.
Soak the dirt with plenty of water and rinse as well as possible.
Clean the vehicle with a soft sponge, a washing glove or a washing brush . Work
from the top to the bottom – starting with the roof.
Only use a car shampoo for stubborn dirt.
Wash out the sponge or washing glove thoroughly at short intervals.
Clean wheels, door sills and similar parts last. Use a second sponge for such
areas.
Give the vehicle a good rinse after washing it and dry it off using a chamois leath- er.
152General Maintenance
Full wheel trimFirst read and observe the introductory information and safety warn-
ings
on page 175.
Extracting
›
Hook the clamp found in the vehicle tool kit into the reinforced edge of the wheel trim.
›
Push the wheel wrench through the clamp, support on the tyre and pull off the
wheel trim.
Installing
›
Press the wheel trim onto the wheel rim at the designated valve opening.
›
Then press the trim into the wheel rim until its entire circumference locks cor- rectly in place.
CAUTION
■ Use the pressure of your hand only, do not strike the full wheel trim. Avoid
heavy impacts when the trim has not yet been inserted into the wheel rim. This
could cause damage to the guide and centring elements of the trim.■
When using the anti-theft wheel bolt, ensure that it is in the hole in the valve
area » page 186 , Securing wheels against theft .
■
If wheel trims are retrofitted it must be ensured that an adequate flow of air is
assured to cool the brake system.
Wheel bolts
Fig. 145
Remove the capFirst read and observe the introductory information and safety warn-
ings on page 175.
Extracting
›
Push the extraction pliers » page 183 sufficiently far onto the cap until the in-
ner catches of the pliers are positioned at the collar of the cap » Fig. 145.
›
Remove the cap.
Installing
›
Push the caps onto the wheel bolts up to the stop.
The wheel bolt caps are housed in a plastic box in the spare wheel or in the stor-
age space for the spare wheel.
Wheel bolts
First read and observe the introductory information and safety warn-ings
on page 175.
Wheels and wheel bolts are matched to each other in terms of design. Each time
you fit other wheels rims, e.g. light alloy wheel rims or wheels with winter tyres,
you must also use the matching wheel bolts with the correct length and dome
shape. This is a prerequisite for ensuring that wheels are attached correctly.

180General Maintenance
›Grasp the end of the wrench and turn the bolt against the direction of the ar-
row » Fig. 150 until it is tight.WARNINGUndo the wheel bolts only a little (about one turn) provided that the vehicle
has not yet been jacked up. Otherwise the wheel could come off and fall down – risk of injury!
Note
If it proves difficult to undo the bolts, carefully apply pressure to the end of the
wrench with your foodt. Keep hold of the vehicle when doing so, and make sure
you keep your footing.
Raising the vehicle

Jacking points for positioning
lifting jack
Fig. 152
Attach lifting jack
First read and observe the introductory information and safety warn-
ings on page 184.
Position the lifting jack below the jacking point closest to the faulty
wheel » Fig. 151 . The jacking point is located directly below the engraving in the
lower sill.
›
Position the lifting jack below the jacking point with the crank and move it up until its claw is positioned below the vertical web of the lower sill.
›
Align the lifting jack so that its claw grasps the web » Fig. 152 - .
›
Support the base plate of the lifting jack with its entire surface resting on level
ground and ensure that the lever is positioned vertically to the point at which the claw grasps the web » Fig. 152 - .
›
Continue turning up the jack until the wheel is just about lifted off the ground.
WARNING■
Only raise the vehicle at the attachment points.■Choose a flat and firm surface for jacking the vehicle.
