It is normal for the dashboard indicator lights to illuminate when the ignition switch is turned on. This is the vehicle's system performing a self-diagnosis, and the lights will automatically turn off after a period of time. However, if any of the following malfunction indicator lights remain illuminated, it indicates a fault in the corresponding system. Immediate inspection and repair are recommended to avoid safety hazards. For new cars, warranty claims may apply. Common malfunction indicator lights and their causes are as follows: 1.
