Tyre pressures 3 190. Always inflate
tyres to the pressures shown on the label on the driver's door frame.
The tyre pressure data refers to cold
tyres. It applies to summer and winter tyres.
Always inflate the spare tyre to the
pressure specified for full load.
Incorrect tyre pressures will impair
safety, vehicle handling, comfort and
fuel economy and will increase tyre
wear.
Tyre pressures differ depending on
various options. For the correct tyre
pressure value, follow the procedure
below:
1. Identify the engine identifier code.
Engine data 3 180.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 190.
For the tyres approved for your
vehicle, refer to the EEC Certificate of
Conformity provided with your vehicle
or other national registration
documents.The driver is responsible for correct
adjustment of tyre pressure.9 Warning
If the pressure is too low, this can
result in considerable tyre warm-
up and internal damage, leading to tread separation and even to tyre
blow-out at high speeds.
Tyre pressure monitoring
system
The Tyre Pressure Monitoring
System (TPMS) uses radio and
sensor technology to check tyre
pressure levels.
Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Tyre pressures in display The current tyre pressures can be
shown in the Driver Information
Centre 3 88.

6. Screw the filler hose to the tyrevalve.
7. The switch on the compressor must be set to O.
8. Connect the electrical connection cable to the power outlet or
cigarette lighter socket.
To avoid discharging the vehicle
battery, we recommend running
the engine.9. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
10. The compressor pressure gauge briefly indicates up to 6 bar(600 kPa/87 psi). Then the
pressure starts to drop.
11. All of the sealant is pumped into the tyre. Then the tyre is inflated.12. The prescribed tyre pressureshould be obtained within
15 minutes. Tyre pressure
3 190 . When the correct pressure
is obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 15 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation
(approx. 2 metres). Reattach the
tyre repair kit and continue the
filling procedure for 15 minutes. If
the prescribed tyre pressure is still not obtained, the tyre is too badly

164Vehicle care
Replace the used sealant bottle.Dispose of the sealant bottle as
prescribed by applicable laws.
Wheel changing
Some vehicles are equipped with a
tyre repair kit instead of a spare wheel 3 161.
Make the following preparations and
observe the following information:
■ Park the vehicle on a level, firm and
non-slippery surface. The front wheels must be in the straight-
ahead position.
■ Apply the parking brake and engage first gear or reverse gear.
■ Remove the spare wheel 3 165.
■ Never change more than one wheel
at a time.
■ Use the jack only to change wheels
in case of puncture, not for a
seasonal winter or summer tyre
change.
■ If the ground on which the vehicle is standing is soft, a solid board
(max. 1 cm thick) should be placed
under the jack.■ Take heavy objects out of the vehicle before jacking up.
■ No people or animals may be in the
vehicle when it is jacked-up.
■ Never crawl under a jacked-up vehicle.
■ Do not start the engine when the vehicle is raised on the jack.
1. Remove the wheel cover (using the hook supplied). Vehicle tools
3 155.
2. Loosen each of the wheel bolts by
half a turn using the wheel
wrench. Ensure the wrench
locates securely. The wrench
should turn anticlockwise to
loosen the bolts. Invert the wrench if necessary.
3. Place lifting pad spigot of the jack
under the jacking hole located
nearest the wheel concerned.
Ensure the jack is positioned
correctly. The jack base must be
on the ground directly below the
jacking hole in a manner that
prevents it from slipping.
4. Install wrench onto the jack and raise the vehicle by turning the
wrench until the wheel is clear of
the ground.
