the On Board Diagnostics System
(OBD II). This OBD II system
protects the environment by
ensuring that your vehicle
continues to meet government
emission standards. The OBD II
system also assists the service
technician in properly servicing
your vehicle.
TheCheck Engineindicator light
illuminates when the ignition is
first turned to the ON position to
check the bulb. If it comes on after
the engine is started, one of the
engine's emission control systems
may be malfunctioning. The light
may illuminate without a
driveability concern being noted.
The vehicle will usually be drivable
and will not require towing.
What you should do if the
check engine light illuminates
Light turns on solid:
This means that the OBD II system
has detected a malfunction.
Temporary malfunctions may cause
yourCheck Enginelight to
illuminate. Examples are:
1. The vehicle has run out of fuel.
(The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the
fuel.
3. The fuel cap may not have been
properly installed and securely
tightened.
These temporary malfunctions can
be corrected by filling the fuel tank
Instrumentation

with good quality fuel and/or
properly installing and securely
tightening the gas cap. After three
driving cycles without these or any
other temporary malfunctions
present, theCheck Enginelight
should turn off. (A driving cycle
consists of a cold engine startup
followed by mixed city/highway
driving.) No additional vehicle
service is required.
If theCheck Enginelight remains
on, have your vehicle serviced at
the first available opportunity.
Light is blinking:
Engine misfire is occurring which
could damage your catalytic
converter. You should drive in a
moderate fashion (avoid heavy
acceleration and deceleration) and
have your vehicle serviced at the
first available opportunity.
Under engine misfire
conditions, excessive
exhaust temperatures could
damage the catalytic converter,
the fuel system, interior floor
coverings or other vehicle
components, possibly causing a
fire.
Air bag readiness
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to
flash or remains on, have the
system serviced immediately.

Momentarily illuminates when the
ignition is turned on and the
engine is off. If the light remains
on, continues to flash or fails to
illuminate, have the system
serviced immediately.
Turn signal
Illuminates when the left or right
turn signal or the hazard lights are
turned on. If one or both of the
indicators stay on continuously or

speed.
Engine coolant temperature
gauge
Indicates the temperature of the
engine coolant. At normal
operating temperature, the needle
remains within the normal area
(the area between the ªHº and
ªCº). If it enters the red section,
the engine is overheating. Stop the
vehicle, switch off the ignition and
let the engine cool. Refer to
