Tire Pressure Monitoring

  • Please see the chapter "TIRE PRESSURE FOR COLD TIRES (68 °F/20 °C)" on page 241.

The Tire Pressure Monitoring continuously monitors tire pressure and tire temperature on all four wheels and warns the driver when the tire pressure is too low.

The display as well as the settings for the Tire Pressure Monitoring take place on the on-board computer.

However, you must still adjust the tire pressure on the wheel.

  • The driver is responsible for filling the tires correctly and making the correct settings on the on-board computer.

The Tire Pressure Monitoring offers the following functions:
– Display of the actual tire pressure while the vehicle is in motion.
– Display of the deviation from the required pressure (refilling pressure).
– Display of currently set tire size and type.
– Tire pressure warnings in two stages.

Maintaining Tire Pressure

Driving the vehicle with low tire pressure increases the risk of a tire failure and resulting loss of control. Furthermore, low tire pressure increases rate of wear of the affected tires.

Please note that the Tire Pressure Monitoring is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of Tire Pressure Monitoring low tire pressure telltale. Low tire pressure reduces the road safety of the vehicle and destroys the tire and wheel.

Tire Pressure Monitoring gives a warning about tire damage caused by a natural loss in pressure as well as about a gradual loss of pressure caused by foreign objects.

Tire Pressure Monitoring cannot warn you about tire damage that occurs suddenly (e.g. flat tire due to abrupt external effects).

  • Incomplete entries or selection of the wrong tires on the on-board computer affect the accuracy of warnings and messages. The settings in the tire pressure menu must be updated following a wheel change or changes in vehicle loading.
  • When a flat tire has been displayed, immediately stop in a suitable place and check the tires for damage. If necessary, remedy the damage with a tire sealant.
  • Do not by any means continue to drive with damaged tires.
