When the Light Flashes First and Then is

On Steady

This indicates that there could be a problem with the

Tire Pressure Monitor System. The light ﬂashes

for about a minute and stays on steady for the remainder

of the ignition cycle. This sequence repeats with

every ignition cycle. See Tire Pressure Monitor System

on page 5-64 for more information.

Malfunction Indicator Lamp

Check Engine Light

A computer system called OBD II (On-Board

Diagnostics-Second Generation) monitors operation

of the fuel, ignition, and emission control systems.

It ensures that emissions are at acceptable levels for

the life of the vehicle, helping to produce a cleaner

environment.

This light should come on

when the ignition is on, but

the engine is not running,

as a check to show it

is working. If it does not,

have the vehicle serviced

by your dealer/retailer.

If the check engine light comes on and stays on, while

the engine is running, this indicates that there is an

OBD II problem and service is required.

Malfunctions often are indicated by the system before

any problem is apparent. Being aware of the light

can prevent more serious damage to the vehicle.

This system assists the service technician in correctly

diagnosing any malfunction.

Notice: If the vehicle is continually driven with this

light on, after a while, the emission controls might

not work as well, the vehicle’s fuel economy might

not be as good, and the engine might not run as

smoothly. This could lead to costly repairs that might

not be covered by the vehicle warranty.
