This system is called OBD II (On-Board

Diagnostics-Second Generation) and is intended to

assure that emissions are at acceptable levels for the

life of the vehicle, helping to produce a cleaner

environment. The Check Engine light comes on to

indicate that there is a problem and service is required.

Malfunctions often will be indicated by the system

before any problem is apparent. This may prevent more

serious damage to your vehicle. This system is also

designed to assist your service technician in correctly

diagnosing any malfunction.

Notice: If you keep driving your vehicle with this

light on, after awhile, your emission controls

may not work as well, your fuel economy may not

be as good, and your engine may not run as

smoothly. This could lead to costly repairs that may

not be covered by your warranty.

Notice: Modiﬁcations made to the engine,

transaxle, exhaust, intake, or fuel system of your

vehicle or replacement tires that do not match your

vehicle’s original tires can affect your vehicle’s

emission controls and may cause this light to come

on. Modiﬁcations to these systems could lead to

costly repairs not covered by your warranty.

This may also result in a failure to pass a required

Emission Inspection/Maintenance test. See

Accessories and Modiﬁcations on page 5-3.

When the ignition is on, this light should come on and

should go out after a few seconds as a check to

show you it is working. If the light does not come on,

have it repaired.

This light will also come on during a malfunction in one

of two ways:

• Light Flashing — A misﬁre condition has been

detected. A misﬁre increases vehicle emissions

and may damage the emission control system on

your vehicle. Diagnosis and service may be

required.

• Light On Steady — An emission control system

malfunction has been detected on your vehicle.

Diagnosis and service may be required.

If the Light Is Flashing

The following may prevent more serious damage to

your vehicle:

• Reducing vehicle speed

• Avoiding hard accelerations

• Avoiding steep uphill grades

If the light stops ﬂashing and remains on steady, see “If

the Light Is On Steady” following.
