1. Check the tyre pressure in all tyres with a
tyre pressure gauge.
2. Inflate the tyre/tyres to the correct pressure
in accordance with the tyre pressure label on
the driver's side door pillar (between front
and rear doors).
3.
Recalibrate the TM system in MY CAR.
NOTE
To avoid incorrect tyre pressure, the pressure
should be checked on cold tyres. "Cold tyres"
means the tyres are the same temperature as
the ambient temperature (approx. 3 hours
after the car has been driven). After a few kil-
ometres of driving, the tyres warm up and the
pressure increases.
WARNING
•
Incorrect tyre pressure may lead to tyre
failure, which could result in the driver
losing control of the car.
•
The system cannot indicate sudden tyre
damage in advance.
TM calibration
In order for TM system to work correctly, a refer-
ence value for the tyre pressure must be deter-
mined. This must be done each time the tyres are
changed or the tyre pressure is adjusted by reca-
librating the system in MY CAR.
For example, the tyre pressure should be
adjusted when driving with a heavy load or for
high-speed driving (above 160 km/h (100 mph)).
Following which, the system must be recalibrated.
Recalibration
Settings are made using the centre console's
controls, see MY CAR (p. 117).
1. Stop the engine.
2. Inflate all tyres to the desired pressure in
accordance with the tyre pressure label on
the driver's side door pillar (between front
and rear doors).
Or see the tyre pressure table.
3. Start the engine and let the car stand still.
4.
Open the menu system MY CAR and select
the menu
Tyre monitor.
5.
Select
Calibrate tyre pressure and press
OK.
6. Press OK after all tyres have been checked
and adjusted in order to start calibration.
7. Drive the car.
> Recalibration is carried out automatically
while the car is being driven and can be
interrupted at any time. If the engine is
switched off while recalibration is in pro-
gress then it is resumed when the car is
driven again. The system provides no con-
firmation when the calibration is complete.
The new reference value applies until steps 1-7
are repeated.
NOTE
Remember that the TM system must be reca-
librated at each tyre change or if the tyre
pressure is adjusted. If new reference values
are not stored then the system cannot func-
tion properly.
NOTE
•
After a tyre has been inflated, always refit
the dust cap in order to avoid damage to
the valve from gravel, dirt, etc.
•
Only use plastic dust caps. Metal dust
caps can rust and become difficult to
unscrew.
