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+ Electronic Immobilizer Operation on page 2-29for more information.

SERVICE TIRE MONITOR SYSTEM

On vehicles with the Tire Pressure Monitor System (TPMS), this message displays if a part on the 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 3-35. Several conditions may cause this message to appear. See Tire Pressure Monitor Operation on page 6-63for more information. If the warning comes on and stays on, there may be a problem with the TPMS. See 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 5-6for 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 5-29. To turn the StabiliTrak system on or off, see StabiliTrak® System on page 5-6.

There are several conditions that can cause this message to appear.

•One condition is overheating, which could occur if StabiliTrak activates continuously for an extended period of time.

•The message also displays if the brake system warning light is on. See Brake System Warning Light on page 3-33.

•The message could display if the stability system takes longer than usual to complete its diagnostic checks due to driving conditions.
