Black plate (60,1)Cadillac DTS Owner Manual - 2011Tire Pressure Monitor SystemThe Tire Pressure Monitor System (TPMS) uses radioand sensor technology to check tire pressure levels.The TPMS sensors monitor the air pressure in yourvehicle's tires and transmit tire pressure readings to areceiver located in the vehicle.Each tire, including the spare (if provided), should bechecked monthly when cold and inflated to the inflationpressure recommended by the vehicle manufactureron the vehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size than the sizeindicated on the vehicle placard or tire inflation pressurelabel, you should determine the proper tire inflationpressure for those tires.)As an added safety feature, your vehicle has beenequipped with a tire pressure monitoring system(TPMS) that illuminates a low tire pressure telltale whenone or more of your tires is significantly under‐inflated.Accordingly, when the low tire pressure telltaleilluminates, you should stop and check your tiresas soon as possible, and inflate them to the properpressure. Driving on a significantly under‐inflated tirecauses the tire to overheat and can lead to tire failure.Under‐inflation also reduces fuel efficiency and tiretread life, and may affect the vehicle's handling andstopping ability.Please note that the TPMS is not a substitute for propertire maintenance, and it is the driver's responsibility tomaintain correct tire pressure, even if under‐inflationhas not reached the level to trigger illumination of theTPMS low tire pressure telltale.Your vehicle has also been equipped with a TPMSmalfunction indicator to indicate when the system is notoperating properly. The TPMS malfunction indicator iscombined with the low tire pressure telltale. When thesystem detects a malfunction, the telltale will flashfor approximately one minute and then remaincontinuously illuminated. This sequence will continueupon subsequent vehicle start‐ups as long as themalfunction exists.When the malfunction indicator is illuminated, thesystem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occurfor a variety of reasons, including the installation ofreplacement or alternate tires or wheels on the vehiclethat prevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on your vehicle toensure that the replacement or alternate tires andwheels allow the TPMS to continue to function properly.See Tire Pressure Monitor Operation on page 6‑61 foradditional information.6-60
