The following warning lamps and indicators alert you to a vehicle condition that may become serious. Some lamps illuminate when you start your vehicle to make sure they work. If any lamps remain on after starting your vehicle, refer to the respective system warning lamp for further information.
Note:
Some warning indicators appear in the information display and function the same as a warning lamp but do not display when you start your vehicle.

Illuminates when you switch it off. | |
Battery
If it illuminates while driving, it indicates a malfunction. Switch off all unnecessary electrical equipment and have the system checked by an authorized dealer immediately. | |
Brake System
Indicates low brake fluid level or a brake system malfunction. Have the system checked immediately by an authorized dealer.

This light may also illuminate momentarily if the engine is running and the driver turns the steering wheel fully in one direction while braking. If the light remains on while the engine is running, this indicates inadequate hydraulic booster pressure or reserve pump system failure. Stop the vehicle as soon as possible and seek service immediately by your authorized dealer. | |
Low Fuel Level (Gasoline Engine Only)
Illuminates when the fuel level is low or the fuel tank is nearly empty. Refuel as soon as possible. | |

If the park brake lamp does not illuminate at these times, seek service immediately. Vehicles equipped with the power park parking brake option: If the park brake warning lamp begins to blink after setting the parking brake, this may indicate a failure in the parking brake system. Seek service from an authorized dealer immediately. Driving extended distances with the parking brake engaged can cause brake failure and the risk of personal injury. | |

The service engine soon indicator light illuminates when you first switch on the ignition, before starting the engine, to check the bulb and to indicate whether the vehicle is ready for Inspection/Maintenance (I/M) testing.
If the service engine soon indicator light stays illuminated after you start the engine, it indicates that the On-Board Diagnostics (OBD-II) system has detected a malfunction of the vehicle emissions control system.
