What you should do if the check engine light illuminates

Light turns on solid:

This means that the OBD II system has detected a malfunction.

Temporary malfunctions may cause your Check Engine light to

illuminate. Examples are:

1. The vehicle has run out of fuel. (The engine may misfire or run

poorly.)

2. Poor fuel quality or water in the fuel.

3. The fuel cap may not have been properly installed and securely

tightened.

These temporary malfunctions can be corrected by filling the fuel tank

with good quality fuel and/or properly installing and securely tightening

the gas cap. After three driving cycles without these or any other

temporary malfunctions present, the Check Engine light should turn off.

(A driving cycle consists of a cold engine startup followed by mixed

city/highway driving.) No additional vehicle service is required.

If the Check Engine light remains on, have your vehicle serviced at the

first available opportunity.

Light is blinking:

Engine misfire is occurring which could damage your catalytic converter.

You should drive in a moderate fashion (avoid heavy acceleration and

deceleration) and have your vehicle serviced at the first available

opportunity.

Under engine misfire conditions, excessive exhaust temperatures

could damage the catalytic converter, the fuel system, interior

floor coverings or other vehicle components, possibly causing a fire.

Door ajar

Illuminates when the ignition is in

the ON or START position and any

door is open.
