Vehicle care237Directional tyresDirectional tyres should be mounted
so that they rotate in the correct
direction. The proper rotation
direction is indicated by a symbol (e.g. an arrow) on the sidewall.
Tyre pressure
Check the pressure of cold tyres at
least every 14 days and before any
long journey. Do not forget the spare
wheel. This also applies to vehicles
with tyre pressure monitoring system.
Tyre pressure 3 271.
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 3 268.
2. Identify the respective tyre.
The tyre pressure tables show all
possible tyre combinations 3 271.
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.
9 Warning
For specific tyres the
recommended tyre pressure as
shown in the tyre pressure table may exceed the maximum tyre
pressure as indicated on the tyre.
Never exceed the maximum tyre
pressure as indicated on the tyre.
Temperature dependency
The tyre pressure depends on the
temperature of the tyre. During
driving, tyre temperature and
pressure increase. Tyre pressure
values provided on the tyre
information label and tyre pressure
chart are valid for cold tyres, which means at 20 °C.
The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
242Vehicle care8. All of the sealant is pumped intothe tyre. Then the tyre is being
inflated.
9. The prescribed tyre pressure should be obtained within ten
minutes.
Tyre pressure 3 271.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within ten minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
ten minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button.
Do not run the compressor longer than ten minutes.
10. Detach the tyre repair kit. Stow tyre repair kit in load
compartment.
11. Remove any excess sealant using a cloth.12. Start driving immediately so thatsealant is evenly distributed in the
tyre. After driving approx.
three miles but no more than ten
minutes, stop and check tyre
pressure. Turn selector on the kit
to the air pump symbol. Connect
compressor air hose to tyre valve. Fill tyre as described before. Drain excess tyre pressure with the
button on the kit.
If tyre pressure hasn't decreased
under 150 kPa (1.5 bar), set it to
the correct value. Otherwise the
vehicle must not be used. Seek
assistance of a workshop. 3 271
