Initializing system The initialization finishes during driving, which can be interrupted at any time. When driving resumes, the initialization is continued automatically. The system is initialized after this activation phase. The initialization process adopts the set inflation tire pressures as reference values for the detection of a flat tire. Initialization is started by confirming the inflation pressures.< iDrive, for operating principle refer to page 16: 1. "Vehicle Info" 2. "Vehicle status" 3. "Reset" 3. Replace the damaged wheel, refer to Changing wheels on page 226. Run-flat tires* 1. Cautiously reduce speed to below 50 mph/ 80 km/h. Avoid severe braking and steering maneuvers and do not exceed a speed of 50 mph/80 km/h. If the vehicle is not equipped with runflat tires, refer to page 208, 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. 94 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 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 con- 4. Start the engine - do not drive away. 5. Start the initialization using "Reset". "Activating..." is displayed on the Control Display. 6. Start to drive. The initialization finishes during driving, which can be interrupted at any time. "Flat Tire Monitor 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. 1. Reduce speed and stop the vehicle carefully. Avoid sudden braking and steering maneuvers. 2. Identify damaged tire. If identification is not possible, contact a BMW center.< 89 Online Edition for Part no. 01 41 2 602 678 - © 08/09 BMW AG Reference Mobility Communications Entertainment Navigation Driving tips Controls At a glance
