Warning Lights,
Gages, and Indicators
Warning lights and gages can
signal that something is wrong
before it becomes serious enough
to cause 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.

could be damaged, and it might
not be covered by the vehicle
warranty. Never drive with the
engine coolant temperature
warning light on.
If this light comes on and stays on,

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 should come on when
the ignition is on, but the engine
is not running, as check to show
it is working. If it does not, have
the vehicle serviced by your
dealer/retailer.
4-18 Instruments and Controls
ProCarManuals.com

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. 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 vehicle 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 vehicle warranty. This could
also result in a failure to
pass a required Emission
Inspection/Maintenance test.
SeeAccessories and
Modifications on page 9-3.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 8-36. 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 8-34.
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 with the engine
running, or if the key is in the
ON/RUN and the light is not on.
4-20 Instruments and Controls
ProCarManuals.com

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 ready for
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 briey 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.
