Have you recently changed brands of fuel?

If so, be sure to fuel your vehicle with quality fuel.

See Gasoline Octane on page 5-6. Poor fuel quality

causes the engine not to run as efficiently as

designed. You might notice this as stalling after

start-up, stalling when you put the vehicle into gear,

misﬁring, hesitation on acceleration, or stumbling

on acceleration — these conditions might go away

once the engine is warmed up. This will be detected by

the system and cause the light to turn on.

If you experience one or more of these conditions,

change the fuel brand you use. It will require at least

one full tank of the proper fuel to turn the light off.

If none of the above steps have made the light

turn off, your dealer/retailer can check the vehicle.

Your dealer/retailer has the proper test equipment and

diagnostic tools to ﬁx any mechanical or electrical

problems that might have developed.

Emissions Inspection and

Maintenance Programs

Some state/provincial and local governments have or

might begin programs to inspect the emission control

equipment on your vehicle. Failure to pass this

inspection could prevent you from getting a vehicle

registration.

Here are some things you need to know to help your

vehicle pass an inspection:

Your vehicle will not pass this inspection if the check

engine light is on or not working properly.

Your vehicle will not pass this inspection if the OBD

(on-board diagnostic) system determines that critical

emission control systems have not been completely

diagnosed by the system. The vehicle would be

considered not ready for inspection. This can happen

if you have recently replaced the battery or if the battery

has run down. The diagnostic system is designed to

evaluate critical emission control systems during normal

driving. This can take several days of routine driving.

If you have done this and your vehicle still does not pass

the inspection for lack of OBD system readiness, your

dealer/retailer can prepare the vehicle for inspection.
