6. Start driving. It takes at least 10 minutes before the Flat Tire Monitor is once again able to detect and report a flat tire. The initialization is completed during driving. To exit the menu: Select the arrow and press the controller. > With medium load: 2 persons, luggage compartment full, or 4 persons without luggage: approx. 95 miles/150 km. > With full load: 4 or more persons, luggage compartment full: approx. 30 miles/50 km. 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 distances, 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 come off and cause an accident. Do not continue driving, contact your BMW center.< Indication of a flat tire The warning lamp lights up red and a message appears on the Info Display. In addition, a signal sounds. A flat tire or a major air loss has occurred. 1. Reduce speed and stop the vehicle carefully. Avoid sudden braking and steering maneuvers. 2. Identify the damaged tire. If identification is not possible, contact your BMW center.< 3. Replace the damaged tire, refer to Changing wheels on page 215. Malfunction The warning lamp lights up yellow and a message appears on the Info Display. The Flat Tire Monitor has failed. Have the system checked as soon as possible. Run-flat tires* 1. Cautiously reduce the vehicle speed to below 50 mph/80 km/h. Avoid hard braking and steering maneuvers and do not exceed 50 mph/80 km/h. If the vehicle is not equipped with runflat tires, refer to page 205, do not continue to drive. Continued driving after a flat tire can result in serious accidents.< 2. Check the air pressure in all four tires at the next opportunity. 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 a total loss of inflation pressure, 0 psi/kPa, or obvious tire damage, you can estimate the possible distance for continued driving on the basis of the following guide values: > With low load: 1 to 2 persons without luggage: approx. 155 miles/250 km. TPM Tire Pressure Monitor* The concept TPM checks the tire inflation pressure in the four mounted tires. The system indicates if the tire inflation pressure has dropped considerably in one or several tires. Functional requirement In order to assure the reliable reporting of a flat tire, the system must have been reset with the correct tire inflation pressure. Always use wheels with TPM electronics; otherwise, the system cannot be assured of functioning properly. Reset the system again after each correction of the tire inflation pressure and after every tire or wheel change.< 91 Online Edition for Part no. 01 41 0 013 316 - © 02/07 BMW AG Reference Mobility Communications Entertainment Navigation Driving tips Controls At a glance
