This symbol illuminates to indicate low tyre pressure. Check the tyre pressure in the Car status app in the centre display.If there is a fault in the system the tyre pressure warning symbol flashes for approximately one minute and then remains illuminated.
System description
The tyre pressure monitoring system measures differences in rotation speed between the different wheels via the ABS system in order to be able to determine whether they have the correct tyre pressure. If the tyre pressure is too low, the tyre’s diameter is changed and, as a result, so is its rotation speed. By comparing the tyres with each other the system can determine whether one or more tyres have pressure that is too low.

General information on the tyre monitoring system
In the information below, the tyre monitoring system is generally referred to as TPMS.Each tyre, including the spare tyre, should be checked once a month. When checking, the tyre should be cold and have the air pressure recommended by the car manufacturer specified on the tyre pressure label or in the tyre pressure table. If the car has tyres of a different size than that recommended by the manufacturer, find out what the correct air pressure level is for these.As an extra safety feature, the car is equipped with a tyre pressure monitoring system (TPMS), which shows when the air pressure in one or more tyres is too low. When the indicator symbol for low air pressure is lit, stop and check the tyres as soon as possible and inflate to the correct air pressure.Driving with tyres that have tyre pressure that is too low may cause the tyre to overheat, which can cause a tyre failure. Low tyre pressure also reduces fuel efficiency as well as tyre service life, and can affect car handling and stopping ability. Note that TPMS does not replace regular tyre maintenance. It is the driver’s responsibility to maintain correct tyre pressure, even if the limit for low tyre pressure has not been reached so that the indicator symbol illuminates.The car is also equipped with a TPMS system fault indicator, which indicates when the system is not functioning correctly. The TPMS system fault indicator is combined with the indicator symbol for low tyre pressure. When the system detects a fault, the symbol in the driver display will flash for about one minute and then remain illuminated. This procedure will be repeated when the car is started until the fault has been rectified. When the symbol is illuminated, the system’s ability to detect or warn of low tyre pressure may be affected.A TPMS system fault can occur for several reasons, such as after changing to a spare tyre, or changing tyres or wheels that prevent TPMS from functioning correctly.Always check the indicator symbol for TPMS after changing one or more tyres in order to ensure the new tyre or wheel is working correctly with TPMS.

To bear in mind
- Always save a new tyre pressure in the system after changing a tyre or adjusting tyre pressure.
- The use of snow chains may affect the tyre pressure monitoring system. This is indicated by a symbol and message in the driver display. When the snow chains are removed, all tyres should be checked and adjusted to the recommended tyre pressure. After that, the new tyre pressure needs to be saved in the tyre pressure monitoring system.
- If you change to tyres of a different size to the ones fitted at the factory, the system must be reset by storing a new tyre pressure for these tyres to avoid false warnings.
- If a spare wheel is used, it is possible that the tyre pressure monitoring system will not work correctly due to the differences between the wheels.
- The system does not replace the need for regular tyre inspection and maintenance.
- It is not possible to switch off the tyre pressure monitoring system.
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.
See tyre pressure status in the centre display
With the system for tyre pressure monitoring, tyre pressure status can be viewed in the centre display.
Checking status
Several minutes driving above 35 km/h (22 mph) are required for the system to become active.
Several minutes driving above 35 km/h (22 mph) are required for the system to become active.
- Press
- Tap on Car status to view the tyre pressure status.
Action in the event of warning for low tyre pressure
When the system for tyre pressure warns that tyre pressure is too low, action is required.
- Check and rectify the tyre pressure when the indicator symbol for the system is illuminated and the message for low tyre pressure message is shown.
- Switch off the car.
- Check the tyre pressure in all four tyres with a tyre pressure gauge.
- Inflate the tyres to the correct pressure, see the decal on the door pillar on the driver’s side showing the recommended pressure for factory fitted tyres.
- Always save a new tyre pressure in the system via the centre display after the tyre pressure has been adjusted. This can only be done when the car is running and stationary.
- Note that the indicator symbol does not extinguish until the low tyre pressure has been rectified and storing a new tyre pressure has been started.
- Several minutes of driving are required at a speed above 35 km/h (22 mph) in order for the system to be able to store the new reference value.
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 kilometres of driving, the tyres warm up and the pressure increases.
- 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.
Saving a new reference value for tyre pressure monitoring
In order for the system for tyre pressure monitoring to work correctly, a reference value for the tyre pressure must be saved. This must take place every time the tyres are changed or the tyre pressure is changed so that the system can warn about low pressure correctly.Perform the following procedure to store a new tyre pressure as a reference value in the system:
Switch off the car.
Inflate the tyres to the correct pressure, see the decal on the door pillar on the driver’s side showing the recommended pressure for factory fitted tyres.
- Start the car.
- Press
- Press Car status.
>Press Store pressure. The car must be running and stationary when storing a tyre pressure.
Note
- The Store pressure button is used to save new reference values for tyre pressures in the tyre pressure monitoring system. For safety reasons, it is only available (selectable) when the car is stationary and the engine is running.
- The tyre pressure must be saved after adjusting tyre pressure or changing tyres. Adjust the tyre pressure to the recommended values and press Confirm to save the tyre pressure.
- To avoid mistaken activation of the Store pressure function, it is necessary to confirm in a second step that the tyre pressure should be saved.
- Drive the car until the new tyre pressure has been saved. The new tyre pressure is stored when the car is driven at a speed above 35 km/h (22 mph).
- When sufficient data have been collected for the system to be able to detect low tyre pressure, the animation showing the progress of storing the new reference value disappears from the centre display.
- If storing fails, a message is shown.
Warning
The exhaust gases contain carbon monoxide, which is invisible and odourless, but highly toxic. The procedure to save a new tyre pressure must therefore always be performed outdoors or in a workshop with exhaust extraction.
