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 ensures
that emissions are at acceptable
levels for the life of the vehicle,
helping to produce a cleaner
environment.
This light comes on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer/
retailer.If the check engine light comes
on and stays on, while the engine
is running, this indicates that there
is an OBD II problem and service
is required.
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
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 vehicle warranty.Notice:Modi cations 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. Modi cations to these
systems could lead to costly
repairs not covered by the vehicle
warranty. This could also result
in a failure to pass a required
Emission Inspection/Maintenance
test. SeeAccessories and
Modifications on page 5-3.
This light comes on during a
malfunction in one of two ways:
Light Flashing:A mis re condition
has been detected. A mis re
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 towing a trailer, reduce the
amount of cargo being hauled
as soon as it is possible.
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 checking the
following items:
Make sure the fuel cap is fully
installed. SeeFilling the Tank
on page 5-8. 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, mis ring,
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 5-5.
If none of the above have made the
light turn off, your dealer/retailer can
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 the 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 with the engine
running, or if the key is in
ON/RUN and the light is not on.
The vehicle will not pass
this inspection if the OBD II
(on-board diagnostic) system
determines that critical emission
control systems have not
been completely diagnosed
by the system. The vehicle
would be considered not readyfor inspection. This can happen
if the battery has recently been
replaced 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 II
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.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.Notice:Lack of proper engine oil
maintenance can 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.
The oil pressure light should come
on brie y as the engine is started. If it
does not come on have the vehicle
serviced by your dealer/retailer.
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.
