Technology for driving comfort and safety The status is displayed. Malfunction The small warning lamp flashes in yellow and then lights up continuously; the large warning lamp comes on in yellow. On the Control Display, the tires are shown in gray and a message appears. No punctures can be detected. This type of message is shown in the following situations: > If there is a malfunction Have the system checked. > If a wheel without TPM electronics has been mounted > If TPM is temporarily malfunctioning due to other systems or devices using the same radio frequency. on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has not reached the level at which the TPMS low tire pressure telltale illuminates. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously lit. This sequence will continue upon subsequent vehicle startups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. Message for unsuccessful system reset The warning lamp lights up yellow. A message appears on the Control Display. The system is not reset, e.g. after a wheel change. Check the tire inflation pressure and reset the system, refer to page 86. Declaration according to NHTSA/ FMVSS 138 Tire Pressure Monitoring Systems Each tire should be checked monthly when cold and inflated to the inflation pressure recommended 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 inflation 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 system, TPMS, that illuminates a low tire pressure telltale when one or more of your tires are significantly underinflated. 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 88 Active steering* The concept Active steering varies the turning angle of the front wheels in relation to steering wheel movements. It also varies the steering force required to turn the wheels depending on the speed at which you are driving. When you are driving in the low road speed range, e.g. in a town or when parking, the steering angle is increased, i.e. steering becomes very direct and less effort is required to turn the wheels. In the higher speed range, on the other hand, the steering angle is reduced as the speed increases. This improves the handling of your BMW over the entire speed range.
