2008 Cadillac STS Service and Repair Manual

Known issues on the 2008 STS. One recall is on federal record for this model year, covering 4,586 STS and STS-V vehicles built to that model year. The tire pressure monitoring system fails to meet the federal malfunction-indication requirement of FMVSS No. 138: when the system detects a malfunction, the low tire warning light should flash for about one minute and then stay on for the rest of the ignition cycle, with a driver information center message also displayed, but on affected vehicles those indications do not work, and premature tire failure could result in a loss of control of the vehicle, increasing the risk of a crash. Owners have filed 50 complaints for the year. The factory diagnostic and repair procedures behind that system are here.

From a TPMS warning-light fault to any other service interval on the sedan or the supercharged V, it keeps you on the OEM procedure and the correct specification for your specific 2008 STS.
