an expensive repair or replacement.
Paying attention to the warning lights
and gages could prevent injury.
Warning lights come on when there
may be or is a problem with one
of the vehicle’s functions. Some
warning lights come on briey when
the engine is started to indicate they
are working.Gages can indicate when there may
be or is a problem with one of the
vehicle’s functions. Often gages
and warning lights work together
to indicate a problem with the
vehicle.
When one of the warning lights
comes on and stays on while
driving, or when one of the gages
shows there may be a problem,
check the section that explains
what to do. Follow this manual’s
advice. Waiting to do repairs can
be costly and even dangerous.

Malfunction
Indicator Lamp
Check Engine Light
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation
of the fuel, ignition, and emission
control systems. It makes sure that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.This light comes on briey, as a
check to show it is working, when the
ignition is turned to ON/RUN. If the
light does not come on, see your
dealer/retailer.
If the light stays on it indicates that
there is an OBD II problem and
service is required.
Malfunctions often are indicated by
the system before any problem is
apparent. Heeding the light can
prevent more serious damage to the
vehicle. This system is also designed
to assist the service technician in
correctly diagnosing any malfunction.Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle’s fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
warranty.
Notice:Modications made to
the engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than those
of the same Tire Performance
Criteria (TPC) can affect the
vehicle’s emission controls and
can cause this light to come on.
Modications to these systems
could lead to costly repairs not
covered by the warranty. This
could also result in a failure
to pass a required Emission
Inspection/Maintenance test.
SeeAccessories and
Modifications on page 9-3.
4-20 Instruments and Controls

This light comes on during a
malfunction in one of two ways:
Light Flashing:A misre condition
has been detected. A misre
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
Reduce vehicle speed.
Avoid hard accelerations.
Avoid steep uphill grades.
If the light continues to ash, when
it is safe to do so, stop the vehicle.
Find a safe place to park the vehicle.
Turn the key off, wait at least
10 seconds, and restart the engine.
If the light is still ashing, follow the
previous steps and see your dealer/
retailer for service as soon as
possible.Light On Steady:An emission
control system malfunction has been
detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction
might be corrected by doing
the following:
Make sure the fuel cap is fully
installed. SeeFilling the Tank on
page 8-37. The diagnostic system
can determine if the fuel cap
has been left off or improperly
installed. A loose or missing fuel
cap allows fuel to evaporate into
the atmosphere. A few driving
trips with the cap properly
installed should turn the light off.
If the vehicle has been driven
through a deep puddle of water,
the vehicle’s electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out.
A few driving trips should turn
the light off.
Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these conditions
occurs, change the fuel brand
used. It will require at least one
full tank of the proper fuel to
turn the light off.
SeeGasoline Octane on
page 8-35.
If none of the above have made the
light turn off, have your dealer/retailer
check the vehicle. The dealer/retailer
has the proper test equipment and
diagnostic tools to x 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 getting a vehicle
registration.
Here are some things to know to
help the vehicle pass an inspection:
The vehicle will not pass this
inspection if the check engine
light is on or not working properly.
The 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 the battery has recently beenreplaced 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 this has been done and the
vehicle still does not pass the
inspection for lack of OBD system
readiness, your dealer/retailer can
prepare the vehicle for inspection.
Oil Pressure Light
{CAUTION
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches
re. You or others could be
burned. Check the oil as soon
as possible and have the
vehicle serviced.Notice:Lack of proper engine oil
maintenance may damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
This light comes on briey when the
ignition is turned on as a check to
be sure it works. If it does not, have
the vehicle serviced.
If the light comes on and stays on, it
means that oil is not owing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem.
