WARNING LIGHTS AND CHIMES
Low fuel
Illuminates when the fuel level is
low. The lamp will also illuminate
when the ignition key is turned to
ON and the engine is off.
Check engine
Your vehicle is equipped with a
computer that monitors the
engine's emission control system.
This system is commonly known as
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
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.

damage the catalytic converter,
the fuel system, interior floor

Battery voltage gauge
This gauge shows the battery
voltage when the ignition is in the
ON position. If the pointer moves
and stays outside the normal
operating range (as indicated),
have the vehicle's electrical system
checked as soon as possible.
Engine oil pressure gauge
This shows the engine oil pressure
in the system. Sufficient pressure
exists as long as the needle
remains in the normal range (the
area between the ªHº and ªLº).
If the gauge indicates low
pressure, switch off the engine
immediately. Check the oil level.
Add oil if needed (refer to

in theMaintenance and care
chapter). If the oil level is correct,
have your vehicle checked at your
dealership or by a qualified
technician.
