Instrumentation Check fuel cap (if equipped) Illuminates when the fuel cap is not CHECK installed correctly. Check the fuel FUEL cap for proper installation. When CAP the fuel filler cap is properly re-installed, the light(s) will turn off after a period of normal driving. Continuing to operate the vehicle with the fuel cap mis-installed can activate the Service Engine Soon/Check Engine warning light. It may take a long period of time for the system to detect an improperly installed fuel filler cap. For more information, refer to Fuel filler cap in the Maintenance and care chapter. Air bag readiness Illuminates to confirm that the air bags (front or side) are operational. If the light fails to illuminate, continues to flash or remains on, have the system serviced immediately. Safety belt Illuminates to remind you to fasten your safety belts. For more information, refer to the Seating and safety restraints chapter. Brake system warning To confirm the brake system warning light is functional, it will momentarily illuminate when the ignition is turned to the ON position (alternatively for some vehicles when the ignition is moved from the ON position to START position, the light will momentarily illuminate prior to reaching the START position). It also illuminates if the parking brake is engaged. If the brake system warning light does not illuminate as described, seek service immediately. Illumination after the parking brake is released indicates low brake fluid level or a brake system malfunction and the brake system should be serviced immediately by a qualified technician. Refer to Brakes in the Driving chapter for more information. 10
