					sure. Driving on a significantly under-inflated  
					tire causes the tire to overheat and can lead to  
					tire failure. Under-inflation also reduces fuel ef‐  
					ficiency 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 under-inflation has not reached the  
					level to trigger illumination of the TPMS low  
					tire pressure telltale. Your vehicle has also  
					been equipped with a TPMS malfunction indi‐  
					cator to indicate when the system is not oper‐  
					ating properly. The TPMS malfunction indica‐  
					tor is combined with the low tire pressure  
					telltale. When the system detects a malfunc‐  
					tion, the telltale will flash for approximately one  
					minute and then remain continuously illumi‐  
					nated. This sequence will continue upon sub‐  
					sequent vehicle start-ups as long as the mal‐  
					function 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 replace‐  
					ment or alternate tires or wheels on the vehicle  
					that prevent the TPMS from functioning prop‐  
					erly. Always check the TPMS malfunction tell‐  
					tale 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.

					Declaration according to NHTSA/  
					FMVSS 138 Tire Pressure Monitoring  
					System  
					Each tire, including the spare (if provided)  
					should be checked monthly when cold and in‐  
					flated 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 pres‐  
					sure telltale when one or more of your tires is  
					significantly 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 pres‐  
					FTM Flat Tire Monitor  
					The concept  
					The system detects tire inflation pressure loss  
					on the basis of rotation speed differences be‐  
					tween the individual wheels while driving.  
					In the event of a tire inflation pressure loss, the  
					diameter and therefore the rotational speed of  
					the corresponding wheel changes. This will be  
					detected and reported as a flat tire.
