Performance and Maintenance
Traction Control System (TCS)
The traction control system limits wheel spin. Thesystem turns on automatically every time the vehicle isstarted.
•To turn off traction control, press and releaseiin
front of the shift lever.Filluminates and the
appropriate DIC message is displayed. SeeDICWarnings and Messages on page 4-67.
•Press and release the button again to turn on
traction control.

StabiliTrak®
The vehicle may have the StabiliTrak system thatassists with directional control of the vehicle in difficultdriving conditions. The system turns on automaticallyevery time the vehicle is started. The system cannot beturned off.
For more information, seeStabiliTrak®System onpage 5-5.
Tire Pressure Monitor
This vehicle may have a Tire Pressure MonitorSystem (TPMS).
The Tire Pressure Monitoralerts you when asignificant reduction inpressure occurs in one ormore of the vehicle’s tiresby illuminating the low tirepressure warning light onthe instrument cluster.
The warning light will remain on until the tire pressure iscorrected. The proper tire pressures for your vehicleare listed on the Tire and Loading Information labellocated on the driver side center pillar (B pillar). SeeLoading the Vehicle on page 5-18.
You may notice during cooler conditions that the low tirepressure warning light will appear when the vehicle is firststarted and then turn off as you drive. This may be anearly indicator that your tire pressures are getting low andthe tires need to be inflated to the proper pressure.
Note:The Tire Pressure Monitor can alert you aboutlow tire pressure, but it does not replace normal monthlytire maintenance. It is the driver’s responsibility tomaintain correct tire pressures.
SeeTire Pressure Monitor System on page 6-57andTire Pressure Monitor Operation on page 6-58.

D (Drive) can be used for towing. You may want to shiftthe transmission to 3 (Third) or, if necessary, to alower gear if the transmission shifts too often underheavy loads and/or hilly conditions.
SeeTowing a Trailer on page 5-26for more information.
3 (Third):This position is also used for normaldriving. However, it reduces vehicle speed more thanD (Drive) without using the brakes. You might choose3 (Third) instead of D (Drive) when driving on hilly,winding roads, when towing a trailer, so there is lessshifting between gears and when going down asteep hill.
2 (Second):This position reduces vehicle speed morethan 3 (Third) without using the brakes. You can use2 (Second) on hills. It can help control vehicle speed asyou go down steep mountain roads, but then youwould also want to use the brakes off and on.
Notice:Do not shift into 2 (Second) unless you aregoing slower than 65 mph (105 km/h), or you candamage the engine and/or transmission.
1 (First):This position reduces vehicle speed evenmore than 2 (Second) without using the brakes. You canuse it on very steep hills, or in deep snow or mud.If the shift lever is put in 1 (First) while the vehicle ismoving forward, the transmission will not shift into firstgear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle inone place on a hill using only the acceleratorpedal may damage the transmission. The repair willnot be covered by the vehicle warranty. If youare stuck, do not spin the tires. When stopping on ahill, use the brakes to hold the vehicle in place.
Performance Shifting
If the vehicle has this feature, it can detect a change indriving patterns. If you make an aggressive drivingmaneuver, the vehicle’s transmission automatically shiftsto the lowest possible gear to maximize vehicleperformance. The vehicle will automatically return tonormal operation when you return to normal drivingpatterns.

Using Cruise Control on Hills
How well your cruise control works on hills dependsupon the vehicle speed, load, and the steepness of thehills. When going up steep hills, you might have tostep on the accelerator pedal to maintain the vehicle’sspeed. When going downhill, you might have to brake orshift to a lower gear to keep the vehicle’s speeddown. Applying the brake or shifting into a lower gearends cruise control. If you need to apply the brakeor shift to a lower gear due to the grade of the downhillslope, you might not want to attempt to use thecruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brakepedal, or press the cancel button on the steering wheel.
Erasing Speed Memory
The cruise control set speed memory is erased whenthe cruise control or the ignition is turned off.

Engine Coolant Temperature Gage
This gage shows theengine coolanttemperature.
It indicates when the engine has warmed up and if thecooling system is operating properly. If the gagepointer moves into the shaded area, the engine coolantis too hot and the engine coolant temperature warninglight comes on. SeeEngine Overheating on page 6-27for more information.
Tire Pressure Light
For vehicles with a tire pressure monitoring system, thislight comes on briefly when the engine is started. Itprovides information about tire pressures and the TirePressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires aresignificantly underinflated.
A tire pressure message in the Driver InformationCenter (DIC), can accompany the light. SeeDriverInformation Center (DIC) on page 4-61for moreinformation. Stop and check the tires as soon as it issafe to do so. If underinflated, inflate to the properpressure. SeeInflation - Tire Pressure on page 6-54formore information.

When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the TirePressure Monitor System. The light flashes for abouta minute and stays on steady for the remainder ofthe ignition cycle. This sequence repeats with everyignition cycle. SeeTire Pressure Monitor Operation onpage 6-58for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-BoardDiagnostics-Second Generation) monitors operation ofthe fuel, ignition, and emission control systems. Itensures that emissions are at acceptable levels for thelife of the vehicle, helping to produce a cleanerenvironment.
This light should come onwhen the ignition is on, butthe engine is not running,as a check to show itis working. If it does not,have the vehicle servicedby your dealer/retailer.
If the check engine light comes on and stays on, whilethe engine is running, this indicates that there is anOBD II problem and service is required.
Malfunctions often are indicated by the system beforeany problem is apparent. Being aware of the lightcan prevent more serious damage to the vehicle. Thissystem assists the service technician in correctlydiagnosing any malfunction.
Notice:If the vehicle is continually driven with thislight on, after a while, the emission controlsmight not work as well, the vehicle’s fuel economymight not be as good, and the engine might notrun as smoothly. This could lead to costly repairsthat might not be covered by the vehicle warranty.
Notice:Modifications made to the engine,transmission, exhaust, intake, or fuel system of thevehicle or the replacement of the original tireswith other than those of the same Tire PerformanceCriteria (TPC) can affect the vehicle’s emissioncontrols and can cause this light to come on.Modifications to these systems could lead to costlyrepairs not covered by the vehicle warranty. Thiscould also result in a failure to pass a requiredEmission Inspection/Maintenance test. SeeAccessories and Modifications on page 6-3.
