Low tire pressure message The warning lamp lights up yellow. A message appears on the Control 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. Check whether your vehicle is equipped with standard tires or run-flat tires. You will recognize run-flat tires by a circular symbol containing the letters RSC on the side of the tire, refer to page 199.< > With a medium load: 2 persons, luggage compartment full, or 4 persons without luggage: approx. 95 miles/150 km > With a full load: More than 4 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 distance and altered natural steering characteristics. If unusual vibrations occur while the vehicle is being driven, this can indicate final failure of the damaged tire. Reduce speed and stop as soon as possible; otherwise, pieces of the tire could come loose and cause an accident. Do not continue driving, but instead contact your BMW center.< Standard tires 1. If all four wheels are shown in yellow, identify the damaged tire on the vehicle. 2. Replace the damaged wheel or wheels, refer to Changing wheels on page 209. The spare wheel is equipped with the necessary TPM electronics and when mounted, will also be monitored once the system has been reset. Have the tire replaced by a BMW center or a workshop that is familiar with handling TPM and works according to BMW repair procedures with correspondingly trained personnel. Malfunction The yellow warning light flashes and then lights up continuously. The tires are shown in gray on the Control Display and a message is displayed. No flat tire can be detected. Have system checked. A message like this is displayed in the following situations: > When a malfunction is occurring. Have the system checked. > If a wheel without TPM electronics is mounted. > If TPM is temporarily interfered with by other systems or devices which use the same radio frequency. Run-flat tires* 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 vehicle is not equipped with runflat tires, refer to page 199, do not continue to drive. Continued driving after a flat tire can result in serious accidents.< 2. 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 93 Online Edition for Part No. 01 41 0 012 254 - © 02/06 BMW AG Reference Mobility Communications Entertainment Navigation Driving tips Controls At a glance
