SERVICE SUSPENSION SYSTEM If your vehicle has the Autoride suspension system, this message displays when the Autoride® suspension system is not operating properly. Have your vehicle serviced by your dealer/retailer. ® SERVICE TRACTION CONTROL If your vehicle has StabiliTrak®, this message displays when there is a problem with the Traction Control System (TCS). When this message displays, the system will not limit wheel spin. Adjust your driving accordingly. See your dealer/retailer for service. See StabiliTrak® System on page 4-6 for more information. SERVICE THEFT DETERRENT SYSTEM This message displays when there is a problem with the theft-deterrent system. The vehicle may or may not restart so you may want to take the vehicle to your dealer/retailer before turning off the engine. See PASS-Key® III+ Operation on page 2-24 for more information. STABILITRAK OFF If your vehicle has StabiliTrak®, this message displays when you turn off StabiliTrak®, or when the stability control has been automatically disabled. To limit wheel spin and realize the full benefits of the stability enhancement system, you should normally leave StabiliTrak® on. However, you should turn StabiliTrak® off if your vehicle gets stuck in sand, mud, ice, or snow and you want to rock your vehicle to attempt to free it, or if you are driving in extreme off-road conditions and require more wheel spin. See If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-33. To turn the StabiliTrak® system on or off, see StabiliTrak® System on page 4-6. SERVICE TIRE MONITOR SYSTEM This message displays if a part on the Tire Pressure Monitor System (TPMS) is not working properly. The tire pressure light also flashes and then remains on during the same ignition cycle. See Tire Pressure Light on page 3-47. Several conditions may cause this message to appear. See Tire Pressure Monitor Operation on page 5-75 for more information. If the warning comes on and stays on, there may be a problem with the TPMS. See your dealer/retailer. 3-70
