ReferenceAt a glanceControlsDriving tipsMobility 55Warning of low tire inflation pressureThe warning lamp lights up in yellow. A signal also sounds. There is a flat tire or a significant loss of tire pressure in one or more tires.1.Cautiously reduce speed to 50 mph/80 km/h or lower. Avoid strong braking and steering maneuvers. Do not exceed a maxi-mum speed of 50 mph/80 km/h.If the car is not equipped with Run-Flat Tires, which is the standard equipment by design, refer to page 88, then do not continue driving. Doing so after a tire puncture may result in a severe accident. <2.In the event of complete tire pressure loss, 0 psi/0 kilopascal, you can estimate how far you can continue driving on the basis of the following guidelines:>With a light load:1 person without luggage:approx. 155 miles/250 km>With a medium load:1 person, cargo bay full,or2 persons without luggage:approx. 90 miles/150 km>With a full load:2 persons, cargo bay full:approx. 30 miles/50 kmDrive cautiously. Do not exceed a speed of 50 mph/80 km/h. Driving characteris-tics change if there is a loss of tire pressure. This includes reduced tracking stability in brak-ing, extended braking distance and altered nat-ural steering characteristics.If unusual vibration or loud noises occur during the journey, this may be an indication that the damaged tire has finally failed. Reduce your speed and pull over to the side of the road at a suitable location at the earliest opportunity. Otherwise, parts of the tire could come loose and cause an accident. Do not continue driving. Contact a BMW center. <MalfunctionThe yellow warning lamp flashes and then lights up continuously. A flat tire cannot be detected.This warning is displayed under the following circumstances:>If there is a malfunction;have the system checked.>If a wheel without TPM electronics is mounted.>If other systems or devices that use the same radio frequency temporarily interfere with the TPM.Declaration according to NHTSA/FMVSS 138 TirePressure Monitoring SystemEach tire should be checked monthly when cold and inflated to the inflation pressure recom-mended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire infla-tion pressure label, you should determine the proper tire inflation pressure for those tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitoring sys-tem, TPMS, that illuminates a low tire pressure telltale when one or more of your tires are signif-icantly under-inflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's han-dling and stopping ability. Please note that the TPMS is not a substitute for proper tire mainte-nance, and it is the driver's responsibility to maintain correct tire pressure, even if under-inflation has not reached the level to trigger illu-mination of the TPMS low tire pressure telltale.The TPMS malfunction indicator is combined with the low tire pressure telltale. When the sys-tem detects a malfunction, the telltale will flash for approximately one minute and then remain
