Raising the vehicle
In order to remove the wheel, the vehicle must be raised with
a jack.
– Position the vehicle jack under the door sill at the jacking point
closest to the wheel being changed ⇒fig. 184 -arrows- .
–Wind up the jack under the jacking point until the claw of the jack
is directly below the vertical rib under the door sill.
– Align the jack so that the arm of the jack fits on the rib under the door sill ⇒fig. 185 and the movable base plate of the jack
is flat on the ground.
– Raise the vehicle until the defective wheel is just clear of the ground.Recesses at the front and rear of the door sills mark the jacking points
⇒fig. 184 -arrows- . There is only one jacking point for each wheel. Do not fit
the jack anywhere else.
The distance from the jacking points to the wheel arches is approximately 15
cm at the front and 25 cm at the rear.
An unstable surface under the jack may cause the vehicle to slip off the jack.
Therefore, the jack must be fitted on solid ground offering good support. Use
a large, stable base if necessary. On a hard, slippery surface (such as tiles)
use a rubber mat or similar to prevent the jack from slipping.
WARNING
•Take all precautions so that the base of the jack does not slip. Failure to
do so could result in an accident.•The vehicle can be damaged if the jack is not applied at the correct
jacking points. There is also a risk of injury since the jack can slip off
suddenly if it is not properly engaged.

250Removing and fitting the wheel
For removal and fitting the wheel, the following tasks must be
completed.After loosening the wheel bolts and raising the vehicle with the jack,
change the wheel as described below:
Removing a wheel
– Unscrew the bolts using the hexagonal tool in the handle of the
screwdriver (vehicle tool) and place them on a clean surface
⇒ fig. 186 .
Fitting a wheel
– Screw in the wheel bolts and tighten them lightly using the hexagonal socket in the screwdriver handle.
The wheel bolts should be clean and easily screwed. Before fitting the spare
wheel, inspect the wheel condition and hub mounting surfaces. These
surfaces must be clean before fitting the wheel.
The hexagonal socket in the screwdriver handle makes it easier to turn the
wheel bolts. The reversible screwdriver blade should be removed when the
tool is used for this purpose.
If tyres with a specific direction of rotation are fitted, note the direction of
rotation.
Note
Do not use the hexagonal socket in the screwdriver handle to loosen or
tighten the wheel bolts.Anti-theft wheel bolts
A special adapter is required to turn the anti-theft wheel
bolts.

– Insert the adapter onto the wheel bolt and push it on as far as it
will go ⇒ page 250, fig. 187 .
– Fit the box spanner as far as it will go over the adapter.
– Loosen or tighten the wheel bolt as appropriate.Error code
The code number of the anti-theft wheel bolt is stamped onto the front part of
the adaptor.
The code number should be noted and kept in a safe place, as it is only by
using the code number that a duplicate adaptor can be obtained from an
Authorised Service Centre.Tyres with directional tread pattern
Tyres with directional tread pattern must be fitted so that they
rotate in the correct direction.A directional tread pattern can be identified by arrows on the sidewall that
point in the direction of rotation. Always note the direction of rotation indi-
cated when fitting the wheel. This is important so that these tyres can give
maximum grip and avoid excessive noise, tread wear and aquaplaning.
If, in an emergency, you have to fit the spare wheel so it rotates in the wrong
direction, you must drive extremely carefully. The tyre will not give optimum
performance. This is particularly important when driving on wet roads.
To benefit from the advantages of tyres with this type of tread pattern, the
defective tyre should be replaced as soon as possible so that all tyres again
rotate in the correct direction.
Tyre repair* (Tyre-Mobility-System)General information and safety notes
Repaired tyres are only suitable for temporary use over a
short period.Your vehicle is equipped with a tyre repair kit: the Ty re Mo bil it y Syste m.
In the event of a puncture you will find the TMS, which consists of a sealing
compound and a compressor, located under the floor panel in the luggage
compartment.
The Ty re Mo bil i t y Syste m will reliably seal tyres damaged by foreign bodies,
provided that the cuts or punctures are no larger than approx. 4 mm in diam-
eter.
It is not necessary to remove the foreign body from the tyre.
Fig. 188 The Tyre
Mobility System is not
suitable for repairing this
type of damage to tyres.

If and when
252The sealing compound must not be used in the following cases:•On cuts and punctures larger than 4 mm ⇒page 251, fig. 188 •if the wheel rim has been damaged •if you have been driving with ver y low pressure or a completely flat tyre
How to use the TMS (tyre mobility system) is described in the section
Repairing a tyre ⇒ page 253 and in the instructions supplied with the tyre
sealant can.
The TMS (tyre mobility system) can be used at outside temperatures down to
-20°C.WARNING
After repairing a tyre please note the following points:•Do not drive faster than 80 km/h.•Avoid heavy acceleration, hard braking and fast cornering.•Vehicle handling could be impaired.•Tyres which have been sealed using the Tyre Mobility System are only
suitable for temporary use over a short period.•After using the tyre sealant the tyre pressure monitoring system* may
malfunction. Therefore, please drive carefully to the next available quali-
fied workshop.•The Tyre Mobility System must NOT be used,
− on cuts and punctures larger than 4 mm
− if the wheel rim has been damaged
− if you have been driving with very low pressure or a completely flat
tyre•Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.•Do not allow the sealant to come into contact with your eyes, skin or
clothing.
•If you do come into contact with the sealant immediately rinse the eyes
or skin affected with clean water.•Change clothing immediately if it becomes soiled with the tyre sealant.•Make sure you do not breathe in the fumes!•If any of the tyre sealant is accidentally ingested, immediately rinse the
mouth thoroughly and drink lots of water.
−Do not induce vomiting. Seek medical assistance if needed.•If any allergic reactions should occur get medical help immediately.•Keep the sealant away from children.For the sake of the environment
Used bottles of sealing compound can be returned to the Technical Service
for disposal.
Note
•If sealant should leak out, leave it to dry. When it has dried, you can pull
it off like a piece of foil.•Observe the expiry date stated on the sealing compound can. Have the
sealing compound exchanged by a qualified workshop.

Repairing a tyrePreparations
– If you have a flat tyre or punctu re, park the car as far away from
the flow of traffic as possible.
–Apply the handbrake firmly to prevent the vehicle from moving
accidentally on slopes.
– Engage 1st gear .
– Check whether a repair is possibl e using the Tyre Mobility System
⇒ page 251.
– Ensure that all passengers leave the vehicle and move away from
the danger area ⇒ .
–Take the tyre sealant can and the compressor out of 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 ⇒fig. 189 .
– 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 lowe r 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 su re your pass engers wait in a safe place ( for instance beh ind the
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.
Note
•Do not use the compressor for longer than 6 minutes. Otherwise, it might
overheat. When the compressor has cooled down, you can use it again.•If tyre sealant should leak out, leave it to dry and then pull it off like foil.•After carrying out a tyre repair remember to buy a new tyre sealant can at
a qualified workshop. This will ensure that the Tyre Mobility System is opera-
tive again.•Please observe legal requirements when doing so.
