If functioning properly, the Check Engine warning light comes on when ignition switch is in the ON position and goes out after engine is
started. If light fails to glow with ignition on or remains on when engine is running, a malfunction exists in the electronic engine control
system. System needs to be checked and serviced.
CHARGING SYSTEM WARNING LIGHT
Light comes on when ignition switch is in the ON or START position and goes out after engine is started and alternator is charged. Light may
also glow when there is a heavy electrical load on the system. If light remains on after reducing electrical load, check electrical system.

cool, and then check coolant level.
