Technology for driving comfort and safety rupted at any time. When driving resumes, the reset is continued automatically. On the Control Display, the tires are shown in green and "Status: TPM active" is displayed again. If a flat tire is detected while the system is resetting and determining the inflation pressures, all tires on the Control Display are displayed in yellow. The message "Tire low!" is shown.< If unusual vibration or loud noises occur during the journey, this may be an indication that the damaged tire has finally failed. Reduce your speed and pull over as soon as possible at a suitable location. Otherwise parts of the tire could come loose, resulting in an accident. Do not continue driving. Instead, contact your BMW center.< Malfunction The small warning lamp flashes in yellow and then lights up continuously; the larger warning lamp comes on in yellow. On the Control Display, the tires are shown in gray and a message appears. No punctures can be detected. This type of message is shown in the following situations: > If there is a malfunction Have the system checked. > If a wheel without TPM electronics has been mounted > If TPM is temporarily malfunctioning due to other systems or devices using the same radio frequency. Message for low tire inflation pressure The warning lamps come on in yellow and red. A message appears on the Control Display. In addition, a signal sounds. There is a flat tire or substantial loss of tire pressure. 1. Cautiously reduce speed to below 50 mph/ 80 km/h. Avoid sudden braking and steering maneuvers. Do not exceed a speed of 50 mph/80 km/h. If the car is not equipped with RunFlat Tires, refer to page 207, the standard equipment by design, do not continue driving. Otherwise a severe accident could result after a tire puncture if you continue driving.< 2. In the event of complete pressure loss, 0 psi/0 kPa, you can estimate the possible distance for continued driving on the basis of the following guidelines: > With a light load: 1 to 2 persons without luggage: approx. 155 miles/250 km > With a medium load: 2 persons, cargo bay full, or 4 persons without luggage: approx. 95 miles/150 km > With a full load: 4 persons, cargo bay full: approx. 30 miles/50 km Drive cautiously and do not exceed a speed of 50 mph/80 km/h. In the event of pressure loss, vehicle handling changes. This includes reduced tracking stability in braking, extended braking distance and altered natural steering characteristics. 86 Message for unsuccessful system reset The warning lamp lights up yellow. A message will appear on the Control Display. The system is not reset after a tire has been changed, for example. Check the tire inflation pressure and reset the system, refer to page 85.

If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressure for those tires.
