Technology for comfort, convenience and safety 5. Change to upper field if necessary. Turn the controller until "FTM" is selected and press the controller. If the vehicle is not equipped with runflat tires as intended at the factory, refer to page 220, do not continue driving. Continuing to drive with a flat tire could cause severe accidents.< 2. At the next opportunity, check the air pressure in all four tires. If the tire inflation pressure in all four tires is correct, the Flat Tire Monitor may not have been initialized. The system must then be initialized.< 6. Start the engine, but do not start driving. 7. Select "Reset" and press the controller. 8. Select "Yes" and press the controller. The message "resetting FTM ..." is displayed. 3. In the event of complete tire pressure loss, 0 psi/0 kPa, you can estimate the possible distance for continued driving on the basis of the following guide values: > 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. 94 miles/150 km > With a full load: 4 or more persons, cargo bay full: approx. 30 miles/50 km 9. Start to drive. The initialization finishes during driving. "Status:active" is displayed on the Control Display. Indication of a flat tire The warning lamp lights up red. A message appears on the Control Display. In addition, an acoustic signal sounds. There is a flat tire or extensive inflation pressure loss. If you have deactivated DSC, it will be activated automatically. 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. In case of further air loss of the defective wheel, its position will be indicated to you on the Control Display. Drive reservedly 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. If unusual vibrations or loud noises occur while the vehicle is being driven, this can indicate final failure of the damaged tire. Reduce speed and stop at a suitable location as soon as possible, otherwise pieces of the tire could become detached and cause an accident. Do not continue driving, but instead contact the BMW Sports Activity Vehicle Center.< 88 Online Edition for Part no. 01 41 0 012 501 - © 08/06 BMW AG
