Instrumentation Anti-lock brake system (ABS) (If equipped) Momentarily illuminates when the ignition is turned on and the engine ABS is off. If the light does not illuminate momentarily at start up, remains on or continues to flash, the ABS needs to be serviced. With the ABS light on, the anti-lock brake system is disabled and normal braking is still effective unless the brake warning light also remains illuminated with parking brake released. Turn signal Illuminates when the left or right turn signal or the hazard lights are turned on. If one or both of the indicators stay on continuously or flash faster, check for a burned-out turn signal bulb. Refer to Exterior bulbs in the Maintenance and care chapter. High beams Illuminates when the high beam headlamps are turned on. Charging system Illuminates when the ignition is turned to the ON position and the engine is off. The light also illuminates when the battery is not charging properly, requiring electrical system service. Engine oil pressure (if equipped) Illuminates when the oil pressure falls below the normal range. Stop the vehicle as soon as safely possible and switch off the engine immediately. Check the oil level and add oil if needed. Refer to Engine oil in the Maintenance and Care chapter. 9
