2-69 Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature. If the
gage pointer moves into the
red area, the engine is
too hot!
This reading means the same thing as the warning
light
-- the engine coolant has overheated. You should
stop the car and turn the engine off as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
This warning light should
come on for a few seconds
while you are starting the
engine. If the light doesn't
come on, have it repaired.
Your vehicle is equipped with a low coolant level sensor
(switch and float) that is designed to detect when your
vehicle's coolant level drops below the set limit. If the
low coolant level sensor (under the coolant surge tank)
detects that the level drops while the engine is running,
the low coolant indicator will light and remain lit until
the ignition switch is turned off. Check the coolant level
and add coolant as needed. The light should turn off as
soon as the coolant level is at its proper operating range.

2-70 Malfunction Indicator Lamp
(Check Engine Light)
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On
-Board
Diagnostics
-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. The CHECK ENGINE light comes on to
indicate that there is a problem and service is required.
Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
NOTICE:
Modifications made to the engine, transmission,
exhaust or fuel system of your vehicle or the
replacement of the original tires with other than
those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the CHECK ENGINE light to
come on. Modifications to these systems could
lead to costly repairs not covered by your
warranty. This may also result in a failure to pass
a required Emission Inspection/Maintenance test.

2-71
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:

Reducing vehicle speed.

Avoiding hard accelerations.

Avoiding steep uphill grades.

If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.If the light stops flashing and remains on steady, see ªIf
the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere. A
few driving trips with the cap properly installed should
turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

yellowblue
2-72
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly. See
ªFilling Your Tankº in the Index. It will take a few
driving trips to turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel (see
ªFuelº in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start
-up, stalling when you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.
Oil Pressure Light/Gage
The light and gage tell you if there could be a problem
with the engine oil pressure.
The gage shows the engine
oil pressure in pounds per
square inch (psi). Canadian
vehicles show pressure in
kilopascals (kPa).
The oil light goes on when
you turn the key to ON or
START. It goes off once you
start the engine. That's a
check to be sure the
light works.
If it doesn't come on, be sure to have it fixed so it will
be there to warn you if something goes wrong.

yellowblue
2-73
When the light comes on and stays on, it means that oil
isn't flowing through the engine properly. You could
be low on oil and you might have some other
system problem.
CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Check Oil Light
This light will come on for
a few seconds when the
ignition is turned on. If the
light doesn't come on, have
it repaired.
If the light comes on while starting and stays on for
about one minute or comes on while driving, the engine
oil level should be checked. Prior to checking the oil
level, be sure your vehicle has been shut off for several
minutes and is on a level surface. Check the oil level and
bring it to the proper level. See ªEngine Oilº in
the Index.
Brake To Shift Light
This light will come on to
remind you that you must
press the brake pedal to
shift out of PARK (P).

yellowblue
2-74 Cruise Control Light
This light comes on
whenever you set your
vehicle's cruise control.
Low Washer Fluid Warning Light
This light will come on
when you turn on the
ignition and the windshield
washer fluid container is
less than one
-third full.
Trunk Ajar Light
This light will come on if
your vehicle's trunk is not
completely closed.
Fuel Gage
The fuel gage shows
approximately how much
fuel is in the tank. It works
only when the ignition is
in ON.

yellowblue
2-75
Here are a few concerns some owners have had about
the fuel gage. All of these situations are normal and do
not indicate that anything is wrong with the fuel gage.

At the gas station the gas pump shuts off before
the gage reads F.

The gage may change when you turn, stop or
speed up.
Low Fuel Light
If the fuel level is low,
approximately two gallons
(7.57 L) of fuel remaining
in the fuel tank, a light will
come on and stay on.
When the fuel level reaches one gallon (8.8 L), the light
will flash until fuel is added.
It will also come on for a few seconds when you first
turn on the ignition as a check to show it's working. If it
doesn't come on then, have it fixed.
Fuel Cap Indicator Light (If Equipped)
This light will come on
if the fuel cap has not
been fully tightened, is
missing or has been
improperly installed.
You should recheck your fuel cap to make sure it is
on tight.
If you continue to drive with a loose fuel cap, the
diagnostic system in your vehicle can determine if the
fuel cap has been left off or improperly installed. A
loose or missing fuel cap will allow fuel to evaporate
into the atmosphere. If this happens, the CHECK
ENGINE light may come on. For more information,
see ªMalfunction Indicator Lampº earlier in this section.

2-76 Automatic Transmission Warning Light
(If Equipped)
This light comes on briefly
when the ignition is turned
on. If the light remains on
or lights up while driving,
there may be a fault in the
automatic transmission.
Have your vehicle serviced.
Leveling Indicator Light
This light comes on steady
when the rear load level in
your vehicle changes.Do not drive your vehicle when this light is on. The rear
of your vehicle is too low and part of the body or the
rear axle may be damaged when driving over bumpy
roads. When the light goes out, leveling is complete.
This procedure is automatic
-- you don't have to
do anything.
If the light comes on flashing, there may be a problem
with the leveling system. You should reduce your
vehicle speed and have your vehicle serviced soon.
Brake Pad Wear Indicator Light
This light comes on when
the brake pads on your
vehicle have significantly
worn. The pads will have to
be replaced, so have your
vehicle serviced soon.
