Rectifying low tyre pressure with
tyre monitoring
*
When the tyre monitoring system, Indirect Tyre
Pressure Monitoring System (ITPMS), gives a
warning, the tyre pressure in one or more of the
car's tyres is too low.
Check and rectify the tyre pressure
when the indicator symbol for ITPMS is
illuminated and the message
Tyre
pressure low is shown. Calibrate
ITPMS after the tyre pressure has been adjusted.
1. Check the tyre pressure in all four tyres with
a tyre pressure gauge.
2. Inflate the tyres to the correct pressure as
indicated on the tyre pressure label on the
door pillar on the driver's side.
3. Recalibrate the ITPMS system, see the sec-
tion "Calibrating tyre monitoring".
4. In some cases, it may be necessary to drive
the car for a few minutes at a speed above
30 km/h (20 mph) in order to extinguish the
ITPMS symbol and clear the message.
Note that the ITPMS symbol does not extin-
guish until the low tyre pressure has been
rectified and new calibration has been per-
formed.
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.
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.
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.
