Tire Pressure Monitoring

  • Please see the chapter "BEFORE MOUNTING NEW TIRES CHECK WITH YOUR AUTHORIZED PORSCHE DEALER FOR A CURRENT LIST OF APPROVED TIRES." on page 251.

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).

  • 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.
  • Sealing the tire with tire sealant is only an emergency repair, so you can drive to the next authorized Porsche dealer. The maximum permitted speed is 50 mph (80 km/h).
  • Do not drive with tires whose tire pressure drops again in a short period of time. In cases of doubt, have tires checked by an authorized Porsche dealer.
  • Damaged tires must be immediately replaced by an authorized Porsche dealer.
    Tire repairs are not permissible under any circumstances.
  • If a fault occurs in the Tire Pressure Monitoring (e.g. defective wheel transmitter), contact an authorized Porsche dealer immediately and have the damage repaired.
    The tire pressure will not be monitored at all or will be monitored only partially by defective Tire Pressure Monitoring.
  • Tires lose air over time without a tire defect being present. A tire pressure warning will then appear in the on-board computer display.
    Correct the tire pressure at the next opportunity.
