CHEVROLET IMPALA 2003 8.G Owners Manual

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 can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to ®x any
mechanical or electrical problems that may have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may 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 your battery or if your
battery has run down. The diagnostic system isdesigned to evaluate critical emission control systems
during normal driving. This may 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 GM dealer can prepare the
vehicle for inspection.
Cruise Control Light
Tthe CRUISE light comes
on whenever you set your
cruise control. See
ªCruise Controlº under

Fuel GageThe fuel gage, when the ignition is on, tells you about
how much fuel you have left in your tank.
The gage will ®rst indicate empty before you are out of
fuel, and you should get more fuel as soon as
possible.
Here are four situations you may experience with your
fuel gage. None of these indicate a problem with the fuel
gage.
·At the gas station, the fuel pump shuts off before
the gage reads full.
·It takes a little more or less fuel to ®ll up than the
fuel gage indicated. For example, the gage may
have indicated the tank was half full, but it actually
took a little more or less than half the tank's
capacity to ®ll the tank.
·The gage goes back to empty when you turn off the
ignition.
·The gage pointer moves while cornering, braking or
acceleration.
Message Center
The message center is located below the temperature
gage or the tachometer gage (if equipped) on the
