Technical data How to use the compact temporary spare wheel
Should you ever have a punctured tyre, the compact temporary
spare wheel is only intended for temporary use until you can reach
a workshop. The standard-size road wheel should be refitted as
soon as possible.
Please note the following restrictions when using the compact
temporary spare wheel. The compact temporary spare wheel is
designed specifically for this model. For this reason, do not use a
temporary spare from a different type of vehicle.
Snow chains
For technical reasons, snow chains must not be used on the
compact temporary spare wheel.
If you should have a puncture on one of the front wheels when using
snow chains, fit the compact temporary spare in place of one of the
rear wheels. You can then attach the snow chains to the wheel taken
from the rear and use this wheel to replace the punctured front
wheel.
WARNING
•
The tyre pressures must be checked and corrected as soon as
possible. The tyre pressure of the compact temporary spare wheel
must be 4.2 bar – an incorrectly inflated tyre can cause an acci-
dent.
•
Do not drive faster than 80 km/h - higher speeds can cause an
accident.
•
Avoid heavy acceleration, hard braking and fast cornering – risk
of accident.
•
Never use two or more compact spare tyres at the same time –
risk of accident.
•
No other type of tyre (normal summer or winter tyres) may be
fitted on the compact temporary spare wheel.
Ty r e r e p a i r sGeneral information and safety notes
Repaired tyres are only suitable for temporary use.Your vehicle is equipped with a tyre repair kit: the Tyre Mobility
System (TMS).
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 TMS will reliably seal tyres damaged by foreign bodies,
provided that the cuts or punctures are no larger than approx. 4 mm
in diameter.
It is not necessary to remove the foreign body from the tyre.
The sealing compound must not be used:•
on cuts and punctures larger than 4 mm ⇒fig. 227
•
if the wheel rim has been damaged
•
if you have been driving with very low pressure or a completely
flat tyre .
How to use the TMS is described in the section Repairing a tyre
⇒page 248 and in the instructions supplied with the tyre sealant
can.

Mobility System is NOT
suitable for repairing
this type of damage to
tyres.

Technical data
– 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 245.
– 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 248,
fig. 228.
– 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 the 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.
•
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. You
should obtain professional assistance.

soon as possible with a torque wrench. The correct tight-
ening torque is 120 Nm.
– Have the flat tyre replaced as quickly as possible.
Note•
If you notice that the wheel bolts are corroded and difficult to
turn when changing a wheel, they must be replaced before having
the tightening torque checked.
•
In the interest of safety, drive at moderate speeds until the tight-
ening torque of the wheel bolts has been checked.

– Now fit the crank handle onto the jack by inserting it
in the opening on the knob ⇒page 252, fig. 232. Turn the
crank handle clockwise or anti-clockwise to secure it in
place.
– Raise the vehicle by winding the crank handle until the
defective wheel is clear of the ground.Recesses at the front and rear of the door sills mark the jacking
points ⇒page 252, fig. 231. There is one jacking point for each
wheel. The distance from the jacking points to the wheel arches is
approximately 20 cm at the front and 40 cm at the rear. The jack may
only be applied at the seam of the jacking points shown.
An unstable surface under the jack may cause the vehicle to slip off
the jack. Always provide a firm base for the jack on the ground. If
necessary use a large, strong board or similar support. On a hard,
slippery surface (such as tiles) use a rubber mat or similar to prevent
the jack from slipping.
WARNING
•
Prevent the base of the jack from slipping – risk of injury.
•
The car 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.

Note
Note the code number of the anti-theft wheel bolt and keep it in a
safe place – not in your vehicle.Jump-startingBefore starting the engine
If necessary, the engine can be started by connecting it to
the battery of another vehicle.If the engine should ever fail to start because of a discharged
battery, the battery can be connected to the battery of another
vehicle to start the engine. Suitable jump leads are required.
Both batteries must be rated at 12 Volts. The capacity (Ah) of the
booster battery should not be significantly lower than that of the
discharged battery.Jump leads
The jump leads must be heavy enough to carry the starter current.
Refer to the details given by the manufacturer.
Only use jump leads with insulated battery clamps.
Positive cable – usually red
Negative cable – usually black
WARNING
•
When it is discharged the battery can freeze at temperatures
around 0°C. A frozen battery must first be thawed out before
connecting the jump leads, as it could otherwise explode.
•
Please note the safety warnings referring to working in the
engine compartment ⇒page 221.Note
•
There must be no contact between the two vehicles as otherwise
current could flow as soon as the positive terminals are connected.
•
The discharged battery must be properly connected to the
vehicle's electrical system.
•
Switch off the car telephone if necessary. Details will be given in
the manufacturer's instructions for the car telephone.

Technical data 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 cells 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 compartment 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 block. 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 towbar. You should only
use a towrope if you do not have a towbar.
A towrope should be slightly elastic 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 258 or ⇒page 259.
Driving technique
Towing requires some experience – especially when using a
towrope. Both drivers should be familiar with the technique required
for towing. Inexperienced drivers should not attempt to tow-start or
tow away another vehicle.
