Furthermore, this could cause damage to your vehicle and
possibly also result in an accident.
Note
•
If you cannot continue driving even with run flat tyres please
obtain professional assistance.
•
You should obtain professional assistance if you are in any doubt
regarding the rims and tyres for your vehicle.
Applies to vehicles: with run flat tyresDriving with run flat tyres
Please remember that the vehicle's handling will be
impaired.Driving a vehicle with a deflat ed tyre, or with insufficient
tyre pressure, is an abnormal situation. However, since the
handling of a vehicle equipped with run flat tyres is only
slightly impaired, it is important to remember that you are
driving with a deflated tyre. If you have to make use of the
run flat system please remember the following points:
– The Electronic Stabilisation Program (ESP) must be switched on.
–Do not exceed 80km/h ⇒.
– Anticipate the traffic situation well in advance.
– Be careful when accelerating.
– Avoid unnecessary braking and steering manoeuvres.
– Reduce speed in good time before corners and potential hazards.
Please refer to ⇒page 274, “ When is it no longer possible to
continue driving with the help of the run flat tyres?”
Effects on handling when dr iving with defective tyres
If one of the front tyres is defective , your vehicle will tend to pull
slightly towards that side and braking performance will be
impaired.
A defective rear tyre will also make the vehicle pull slightly to one
side, and the braking response will again be slightly impaired.
These effects will be most noticeable when driving in a corner.
WARNING
•
When using the run flat system the changes in vehicle handling
will be noticeable when braking, in corners and during fast accel-
eration.
•
The maximum permitted speed of 80 km/h is subject to road
and weather conditions. Always observe the relevant rules and
regulations. Run flat tyres allow you to continue your journey in
the event of a loss of tyre pressu re. However, the driver remains
responsible for the safety of the vehicle and for restoring the
correct tyre pressure and having defective parts replaced
⇒ page 276 . For these reasons you should always adjust your
driving to suit the circumstances.Caution
We recommend that you drive with great care when making use of
the run flat system. Avoid abrupt manoeuvres.

Technical data
– Check whether a repair is possible using the Tyre
Mobility System ⇒page 285.
– Ensure that all passengers leave the vehicle and move
away from the danger area ⇒.
– Take the tyre sealant can and the electric compressor out
of the luggage compartment ⇒page 283.
– Fix the sticker “max. 80 km/h”, which is included with the tyre sealant can, onto the instrument cluster 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 286,
fig. 270.
– 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 filling hose of th
e electric compressor 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 pres- sure shown on the pressure gauge.
– If the tyre pressure remains lower than the value speci- fied 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 specifica-
tion the tyre is too badly damaged and cannot be
repaired using the tyre sealant.
Final checks
– 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 profes-
sional assistance.
WARNING
•
If you have a puncture in moving 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 passengers wait in a safe place (for instance
behind 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.

288•
Seek professional assistance if th e 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. You
should obtain professional assistance.Caution
Take special care if you have to repair a tyre on a gradient.
Note
•
Do not use the compressor for longer than 6 minutes at a time,
as it could 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 operative again.
•
Please observe the relevant regulations.
Changing a wheelPreparations
Some preparations are necessary before changing a
wheel.– If you have a flat tyre, stop the car well away from moving traffic. Choose a location that is as level as possible.– All passengers should
leave the car. They should wait in
a safe place (for instance behind the roadside crash
barrier).
– Apply the parking brake to stop the vehicle moving acci-
dentally.
–Engage first gear (manual gearbox) or move selector
lever to position P (automatic gearbox).
– When towing a trailer: unhitch the trailer from your vehicle.
– Take the tools ⇒ page 283 and the spare wheel*
⇒ page 284 out of the luggage compartment.
WARNING
If you have a puncture in moving 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 oppo-
site the wheel being changed by placing a stone or similar object
under it to prevent the vehicle from rolling away.
Note
Please observe the relevant regulations.How to change a wheel
Change the wheel as described below.–Pull off the hub cap . Also refer to ⇒page 289, “Hub
caps”.

Loosening
–Fit the box spanner as far as it will go over the wheel bolt
5).
– Grip the box spanner as close to the end as possible and
turn the wheel bolts about one turn anti-clockwise
⇒ page 289, fig. 272 -arrow-.
Tightening
– Fit the box spanner as far as it will go over the wheel bolt5).
– Grip the box spanner as close to the end as possible and
tighten the bolt firmly by turning clockwise.
WARNING
To avoid accidents, the wheel bolts should only be loosened
slightly (about one turn) before ra ising the vehicle with the jack*.
Note
•
Do not use the hexagonal socket in the screwdriver handle to
loosen or tighten the wheel bolts.
•
If the wheel bolt is very tight, it may be possible to loosen it by
pushing down the end of the spanner carefully with your foot. Hold
on to the car for support and take care not to slip.
Raising the vehicle
The vehicle must be raised with the jack* to remove the
wheel.Each jacking point is marked by a recess underneath the
vehicle ⇒fig. 273.
– Place the jack ⇒page 283 underneath the jacking point
closest to the wheel being changed. Make sure the base
plate is flat on the ground.
– Wind up the jack by the knob until the claw of the jack completely surrounds the seam on your vehicle
⇒ fig. 274.

– Screw in the mounting pin (provided in the vehicle's tool
kit) by hand in place of the wheel bolt ⇒page 291,
fig. 276.
– Then unscrew the other wheel bolts as described above.
– Take off the wheel. The mounting pin stays where it is.
Putting on the spare wheel
– Put on the spare wheel, using the mounting pin to guide it into place.
– Screw in the wheel bolts and tighten them lightly using
the hexagonal opening in the screwdriver handle.
– Then unscrew the mounting pin and tighten the remaining wheel bolt lightly.
– Carry out the steps required after you have changed the wheel ⇒page 289, “After changing a wheel”.The wheel bolts should be clean and turn easily. Before putting on
the spare wheel, inspect the condition of the wheel and hub
mounting surfaces. These surfaces must be clean before mounting
the wheel.
The wheel bolts are easier to remove from the wheel rim if you use
the hexagonal socket in the screwdriver handle. The reversible
screwdriver blade should be removed as a precautionary measure
when the tool is used for this purpose.
Note the direction of rotation when putting on a tyre with direc-
tional tread pattern ⇒page 292 .
Note
Do not use the hexagonal socket in the screwdriver handle to loosen
or tighten the wheel bolts.
Tyres with directional tread pattern
Tyres with directional tread pattern must be mounted so
that they rotate in the correct direction.A directional tread pattern is identified by arrows on the sidewall
pointing in the forward running direction. Always note the direction
of rotation indicated when mounting the wheel. This is important so
that these tyres can give maximum grip and avoid excessive noise,
tread wear and aquaplaning.
Drive carefully should you ever have a puncture and have to mount
the spare wheel so it rotates in the wrong direction. This is because
the tyre will not give optimum performance. Bear this in mind
particularly when driving on wet roads.
To benefit from the advantages of tyres with this type of tread
pattern, the defective tyre should be replaced and refitted as soon
as possible so that all tyres agai n rotate in the correct direction.Applies to vehicles: with anti-theft wheel boltsAnti-theft wheel bolts
A special adapter is required to turn the anti-theft wheel
bolts.

terminal must not touch metal parts of the vehicle: this can cause
short circuiting.
•
Do not bend over the batteries – risk of acid burns.
•
The screw plugs on the battery ce
lls must be screwed in firmly.
•
Keep sparks, flame and lighted cigarettes away from batteries:
the gases given off can cause an explosion.
•
If jump-starting another vehicle, position the jump leads in
such a way that they cannot come into contact with any moving
parts in the engine compart ment of the other vehicle.Caution
Please note that the above method of connecting the leads is meant
for jump-starting your vehicle. If jump-starting another vehicle, you
should not connect the negative lead (–) to the negative terminal of
the discharged battery, but directly to the engine block or a solid
metal part bolted to the engine bl ock. If the battery of the other
vehicle does not have a gas vent, there is a risk that a mixture of
oxygen and hydrogen gas can accumulate and cause an
explosion.Tow-starting and towing awayGeneral notes
Points to observe when tow-starting or towing awayIf you use a towrope:
Notes for the driver of the towing vehicle
– The towrope must be taut before driving off. – Engage the clutch very gently when starting to move; on
vehicles with automatic gearbox press the accelerator
slowly.
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the turn signals, horn, windscreen wipers and washers can be
used. Please ensure that the steering wheel is unlocked
when you switch on the ignition, and that it moves freely.
–Put gear lever in neutral (manual gearbox) or move
selector lever to position N (automatic gearbox).
– The brake servo and power steering only work when the engine is running. Considerably more effort is required
on the brake pedal and steering wheel when the engine
is switched off.
– Ensure that the towrope remains taut at all times when towing.
Towrope or towbar
It is easier and safer to tow a vehicle with a tow bar. You should only
use a tow rope if you do not have a towbar.
A towrope should be slightly elasti c to reduce the loading on both
vehicles. It is advisable to use a towrope made of synthetic fibre or
similar material.
Attach the tow-rope or tow-bar only to the towing anchorages
intended for this purpose ⇒page 296 or ⇒page 297 .
Driving technique
Towing requires some experience – especially when using a
tow rope . Both drivers should be familiar with the technique required
for towing. Inexperienced drivers sh ould not attempt to tow-start or
tow away another vehicle.

Self-help
296Do not pull too hard with the towi ng vehicle and take care to avoid
jerking the towrope. When towing on a loose surface there is always
a risk of overloading and damaging the anchorage points.
Caution
If there is no oil in the gearbox or no lubricant in the automatic
transmission the car may only be towed with the driven wheels
lifted clear of the road, or transported on a special car transporter
or trailer.
Note
•
Note the regulations concerning towing.
•
The hazard warning lights of bo th vehicles must normally be
switched on. However, observe an y regulations to the contrary.
•
Make sure that the towrope is not twisted, as otherwise the front
towline anchorage on your vehicle could work itself loose.
Front towline anchorage
The front towline anchorage is only mounted if the vehicle
has to be towed.
The screw connection for the towline anchorage is located
behind a cover cap on the right side of the front bumper.
– Take the towline anchorage ou t of the vehicle's tool kit
⇒ page 283 .
– To detach the cover cap from the bumper, firmly press the lower part of the cap inwards to release it ⇒fig. 280.
– Screw the towline anchorage firmly all the way into the screw connection ⇒fig. 281.After use, unscrew the towline anchorage and put it back in the
toolbox. Replace the cap in th e bumper. The towline anchorage
should always be kept in the vehicle.
WARNING
If the towline anchorage is not scre wed in as far as the stop, there
is a risk of the screw connection shearing off during towing (acci-
dent risk).
