Warning lights can alert you to a vehicle condition that may become serious enough to cause extensive repairs. A warning light may illuminate when a problem exists with one of your vehicle’s functions.

Many lights will illuminate when you start your vehicle to make sure the bulbs work. If any light remains on after starting the vehicle, refer to the respective system warning light for additional information.

Note: Some warning lights are reconfigurable telltale (RTT) indicators.

These indicators display in the message center and function the same as a warning light but do not display on startup.

Service engine soon: The service engine soon indicator light illuminates when the ignition is first turned on to check the bulb and to indicate whether the vehicle is ready for Inspection/Maintenance (I/M) testing. Normally, the service engine soon light will stay on until the engine is cranked, then turn itself off if no malfunctions are present.

However, if after 15 seconds the service engine soon light blinks eight times, it means that the vehicle is not ready for I/M testing. See the Readiness for Inspection/Maintenance (I/M) testing in the Maintenance and Specifications chapter.

Solid illumination after the engine is started indicates the on-board diagnostics system (OBD-II) has detected a malfunction. Refer to On-board diagnostics (OBD-II) in the Maintenance and Specifications chapter. If the light is blinking, engine misfire is occurring which could damage your catalytic converter. Drive in a moderate fashion (avoid heavy acceleration and deceleration) and contact your authorized dealer as soon as possible.

WARNING: Under engine misfire conditions, excessive exhaust temperatures could damage the catalytic converter, the fuel system, interior floor coverings or other vehicle components, possibly causing a fire.

Powertrain malfunction/reduced power (RTT): Illuminates when a powertrain or an AWD fault has been detected. Contact your authorized dealer as soon as possible.

Brake system warning light: To confirm the brake system warning light is functional, it will momentarily illuminate when the ignition is turned to on when the engine is not running, or in a position between on and start, or by applying the parking brake when the ignition is turned to on. If the brake system warning light does not illuminate at this time, contact your authorized dealer as soon as possible. Illumination after releasing the parking brake indicates low brake fluid level or a brake system malfunction. Contact your authorized dealer as soon as possible.

WARNING: Driving a vehicle with the brake system warning light on is dangerous. A significant decrease in braking performance may occur. It will take you longer to stop the vehicle.

Contact your authorized dealer as soon as possible. Driving extended distances with the parking brake engaged can cause brake failure and the risk of personal injury.

Anti-lock brake system: If the ABS light stays illuminated or continues to flash, a malfunction has been detected. Contact your authorized dealer as soon as possible. Normal braking is still functional unless the brake warning light also is illuminated.

Airbag readiness: If this light fails to illuminate when the ignition is turned on, continues to flash or remains on, contact your authorized dealer as soon as possible. A chime will sound when there is a malfunction in the indicator light.

Safety belt: Reminds you to fasten your safety belt. A Belt-Minder chime will also sound to remind you to fasten your safety belt. Refer to the Seating and Safety Restraints chapter to activate/deactivate the Belt-Minder chime feature.

Charging system (RTT): Illuminates when the battery is not charging properly. If it stays on while the engine is running, there may be a malfunction with the charging system. Contact your authorized dealer as soon as possible. This indicates a problem with the electrical system or a related component.

Engine oil pressure (RTT): Illuminates when the oil pressure falls below the normal range, refer to Engine oil in the Maintenance and Specifications chapter.

AdvanceTrac : Displays when the AdvanceTrac /traction control is active. If the light remains on, have the system serviced immediately, refer to the Driving chapter for more information.

AdvanceTrac off light: Illuminates when AdvanceTrac /traction control has been disabled by the driver. Refer to the Driving chapter for more information.

Low tire pressure warning: Illuminates when your tire pressure is low. If the light remains on at start up or while driving, the tire pressure should be checked. Refer to Inflating your tires in the Tires, Wheels and Loading chapter. When the ignition is first turned to on, the light will illuminate for 3 seconds to ensure the bulb is working. If the light does not turn on or begins to flash, contact your authorized dealer as soon as possible. For more information on this system, refer to Tire pressure monitoring system (TPMS) in the Tires, Wheels and Loading chapter.

Low fuel (RTT): Illuminates when the fuel level in the fuel tank is at or near empty. Refer to Fuel gauge in this chapter.

Speed control (RTT): The speed control system indicator light changes color to indicate what mode the system is in:

• On (gray light): Illuminates when the speed control system is turned on. Turns off when the speed control system is engaged or turned off.
• Engaged (green light): Illuminates when the speed control system is engaged. Turns off when the speed control system is disengaged.

Adaptive cruise control (RTT) (if equipped): The speed control system indicator light changes color to indicate what mode the system is in:

• On (gray light): Illuminates when the adaptive cruise control system is turned on. Turns off when the speed control system is turned off.
• Engaged (green light): Illuminates when the adaptive cruise control system is engaged. Turns off when the speed control system is disengaged.

Heads up display (if equipped): A red bar will illuminate on the windshield in certain instances when using adaptive cruise control and/or the collision warning system. It will also illuminate momentarily when you start your vehicle to make sure the display works. See Using adaptive cruise control in the Driving chapter for more information.

Grade assist (RTT): Illuminates when the grade assist is turned on.

Headlamps on warning chime: Sounds when the headlamps or parking lamps are on, the ignition is off (the key is not in the ignition) and the driver’s door is opened.
