Tyre pressure monitoring (TM)*1
Messages
If the tyre pressure is too low then a warning lamp () illuminates in the combined instrument panel and one of the following messages is shown:
- Tyre pressure low Check front right tyre
- Tyre pressure low Check front left tyre
- Tyre pressure low Check rear right tyre
- Tyre pressure low Check rear left tyre
- Tyre pressure low Check tyres
- Tyre pressure system Service required
- The tyre pressure system is currently not active
Important
The system does not replace normal tyre maintenance.
TM calibration
In order for TM to work correctly, a reference value for the tyre pressure must be determined. This must be performed each time the tyres are changed or the tyre pressure is changed.
Recalibration
The new reference value applies until steps 1-5 are repeated.
Note
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.
System and tyre status
The status is colour-coded for each tyre in accordance with the following:
- All-green: the system is operating normally and the tyre pressure in all tyres is slightly above the recommended level.
- Yellow wheel: corresponding tyre's pressure is too low.
- All wheels yellow: two or more tyres have pressure that is too low.
- All wheels grey and the message The tyre pressure system is currently not active: the tyre pressure system is temporarily deactivated. It may be necessary to drive the car for a short time above 30 km/h before the system becomes active again.
- All wheels grey and the message Tyre pressure system Service required: an error has occurred in the system. Contact a Volvo dealer or workshop.
Clearing warning messages
If a tyre pressure message has been shown and the TM warning lamp has been illuminated:
Note
Warning
- Incorrect tyre pressure may lead to tyre failure, which could result in the driver losing control of the car.
