23. Malfunction Indicator Light
This light is part of an onboard diagnostic
system which monitors the emissions and en-
gine control system. If the vehicle is ready for
emissions testing the light will come on when the
ignition is first turned on and remain on, as a bulb
check, until the engine is started. If the vehicle is not
ready for emissions testing the light will come on
when the ignition is first turned on and remain on for
15 seconds, then blink for 5 seconds, and remain on
until the vehicle is started. If the bulb does not come
on during starting, have the condition investigated
promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.
24. Door Ajar
The Door Ajar light will illuminate when the
ignition is ON and either one of the passen-
ger doors is opened.
25. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading.
26. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.

EMISSION CONTROL SYSTEM MAINTENANCE
The ªScheduledº maintenance services, listed inbold
typeon the following pages must be done at the times or
mileages specified to assure the continued proper func-
tioning of the emission control system. These, and all
other maintenance services included in this manual,
should be done to provide best vehicle performance and
reliability. More frequent maintenance may be needed for
vehicles in severe operating conditions such as dusty
areas and very short trip driving.
Inspection and service also should be done any time a
malfunction is suspected.
NOTE:Maintenance, replacement, or repair of the
emission control devices and systems on your vehicle
may be performed by any automotive repair establish-
ment or individual using any automotive part which has
been certified pursuant to U.S. EPA or, in the State of
California, California Air Resources Board regulations.
EMISSIONS TESTING
In some localities, it may be or will become a legal
requirement to ensure that all emissions components and
systems are functioning properly as a part of the test
procedure. The test center accomplishes this by checking
the On Board Diagnostic System (OBD) system with an
electronic scan tool. If your vehicle has recently been
serviced, the OBD system may have been reset to a9not
ready9condition because the OBD system has not had
sufficient time since the servicing to reconfirm that
emissions components are operating properly. In most
cases, a reasonable mix and amount of normal city and
highway driving and at least one overnight-off period
will be required to prepare your vehicle for this check;
however your dealer has the equipment and procedures
required to make certain that the OBD system of your
vehicle is ready for the required testing.
