254Changing a wheelPreparation work
What you must do before changing a wheel.– If you have a flat tyre or puncture, park the car as far away from
the flow of traffic as possible. Choose a location that is as level
as possible.
– All passengers should leave the vehicle. They should wait in a
safe place (e.g. behind the roadside crash barrier).
–Apply the handbrake firmly.
–Engage 1st gear.
– When towing a trailer: Unhitch the trailer from your vehicle.
–Take the tools and the spare wheel ⇒ page 251 out of the
luggage compartment.
WARNING
If you have a puncture in heavy traffic, switch on the hazard warning lights
and place the warning triangle in a visible location. This is for your own
safety and also warns other road users.
Caution
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so.Changing a wheel
Change the wheel as described below.– Remove the wheel cover.
–Loosen the wheel bolts ⇒ page 255.
– Raise the car with the jack ⇒page 256.
– Ta k e o f f the wheel with the flat tyre and then put on the spare
wheel ⇒page 257.
– Lower the vehicle.
– Tighten the wheel bolts firmly in diagonal sequence with the box
spanner ⇒page 255.
–Replace the cover .After changing a wheel
After changing the wheel, there are still tasks to complete.– Place the wheel with the defective tyre in the spare wheel well
and secure it.
– Put the tools and jack back in the luggage compartment.

– Stick the “max. 80 km/h” adhesive, which is included with the
tyre sealant can, onto the instrument panel where the driver will
see it.
Filling the tyre
– Shake the tyre sealant can well.
– Screw the enclosed filling hose onto the sealant can as far as it will go. This will automatically pierce the foil sealing the can.
– Take the valve cap off the tyre valve and use the enclosed valve insert tool to unscrew the valve insert ⇒page 260, fig. 201 .
– Place the valve insert onto a clean surface.
– Remove the sealing plug from the filling hose and insert the hose into the tyre valve.
– Hold the tyre sealant can upside down and fill the complete contents of the can into the tyre.
– Then disconnect the hose and screw the valve insert firmly back into the tyre valve.
Inflating the tyre
– Screw the compressor filling hose onto the tyre valve and plug the connector into the cigarette lighter.
– Pump the tyre up to 2.0 to 2.5 bar and monitor the pressure shown on the pressure gauge. – If the tyre pressure remains lower than the value specified above
drive the vehicle approx. 10 metres forwards or backwards, so
that the sealant can spread evenly in the tyre. If the pressure is
still lower than the specification the tyre is too badly damaged
and cannot be repaired using the tyre sealant.
Final check
– After about 10 minutes, stop to check the tyre pressure.
– If tyre pressure is less than 1.3 bar, the tyre is too badly damaged. Do not drive on! You should obtain professional
assistance.
WARNING
•If you have a puncture in heavy traffic, switch on the hazard warning
lights and place the warning triangle in a visible location. This is for your
own safety and also warns other road users.•Make sure your pass engers wait in a safe place ( for instance behind t he
roadside crash barrier).•Please observe the manufacturers' safety notes on the compressor and
the instructions supplied with the tyre sealant can.•If it was not possible to build up a tyre pressure of 2.0 bar within 6
minutes this means that the tyre is too badly damaged. Do not drive on!•Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.•If tyre pressure is less than 1.3 bar after driving about 10 minutes, the
tyre is too badly damaged. Do not drive on! Obtain technical assistance.Caution
Take special care if you have to repair a tyre on a slope.

Caution
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could result in fire. It could also cause
damage to other parts of the electrical system.
Note
If a newly replaced fuse blows again after a short time, the electrical system
must be checked by a qualified workshop as soon as possible.Fuse assignment

models or are optional extras.
The electric windows and electric seat adjusters are protected by circuit
breakers . These reset automatically after a few seconds when the overload
(caused for example by frozen windows) has been corrected.

Please note that the above list contains all data at the time of going to press,
so it is subject to modifications. If discrepancies should occur, please refer to
the sticker on the inside of the fuse cover for the correct information for your

BulbsGeneral notesYou can change the following bulbs for exterior lights yourself:•Main headlights: all (except for xenon headlights)•Rear lights: All bulbs•Side indicator bulb
The following bulbs can only be changed by a qualified workshop:•Main headlights: Xenon* bulb ⇒page 271•Front fog lights: Bulb
As a rule, you require a certain degree of practical skill to change defective
bulbs. This applies in particular to those bulbs which are only accessible from
the engine compartment.
If in doubt, we recommend that you have defective bulbs changed by a qual-
ified workshop or qualified mechanic.
If you do decide to change bulbs in the engine compartment yourself, be
aware of the safety risks involved ⇒page 227 ⇒ in “Types of bulbs”.Changing bulbs Halogen headlightsTypes of bulbsYou must only replace a bulb with a bulb of the same type. The name can be

WARNING
•Take particular care when working on components in the engine
compartment if the engine is warm - risk of burns!•Bulbs are highly sensitive to pressure. The glass can break when you
touch the bulb, causing injury.•The high voltage element of gas discharge lamps* (xenon light) must
be handled correctly. Otherwise, there is a risk of death.•When changing bulbs, please take care not to injure yourself on sharp
parts in the headlight housing.Caution
•Remove the ignition key before working on the electric system. If not, a
short circuit could occur.•Switch off the lights or parking lights before you change a bulb.For the sake of the environment
Please ask your specialist retailer how to dispose of used bulbs in the proper
manner.
Note
•Depending on weather conditions (cold or wet), the front lights, the fog
lights, the rear lights and the indicators may be temporarily misted. This does not affect the useful life of the lighting system. By switching on the lights, the
area through which the beam of light is projected will quickly be demisted.
However, the edges may continue to be misted.
•Please check at regular intervals that all lighting (especially the exterior
lighting) on your vehicle is functioning pr operly. This is not only in the interest
of your own safety, but also in that of all other road users.•Before changing a bulb, make sure you have the correct new bulb.•Do not touch the glass part of the bulb with your bare hands, use a cloth
or paper towel instead. Otherwise, the fingerprints left on the glass will
vaporise as a result of the heat generated by the bulb, be deposited on the
reflector and impair its surface.Removing the air duct
The air duct has to be removed to gain access to the bulbs for
the right-side headlight.
