In the following situations, the system could be delayed or malfunction: > System has not been initialized > Driving on snowy or slippery road surface > Sporty driving style: slip in the drive wheels, high lateral acceleration > Driving with snow chains* When you are driving with the compact wheel* the Flat Tire Monitor is unable to function. 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. If the vehicle is not equipped with runflat tires as provided at the factory, refer to page 237, 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.< 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. 95 miles/150 km > With a full load: 4 or more persons, cargo bay full: approx. 30 miles/50 km Drive cautiously and do not exceed speeds of 50 mph/80 km/h or else you run the risk of causing an accident. 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.< 93 Initializing system The initialization finishes during driving, which can be interrupted at any time. When driving resumes, the initialization is continued automatically. Do not initialize the system when driving with snow chains* or with the compact wheel*.< 1. "Vehicle Info" 2. "Vehicle status" 3. "Reset" 4. Start the engine - do not drive away. 5. Start the initialization using "Reset". 6. Start to drive. The initialization finishes during driving. "Status: Flat Tire Monitor active " is displayed again 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.
