2-73 Oil Pressure Gage
The oil pressure gage shows
the engine oil pressure in
psi (pounds per square inch)
when the engine is running.
Canadian vehicles indicate
pressure in kPa
(kiloPascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the red
warning zone indicate the normal operating range.
A reading in the red zone may be caused by a
dangerously low oil level or other problem causing low
oil pressure. On vehicles with the optional DIC, the
CHECK GAGES light will go on and a warning chime
will sound, if you have this option. Driving your vehicle
with low oil pressure can cause extensive
engine damage.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.

2-74 Check Oil Level Warning Light
The CHECK OIL LEVEL
light turns on for three
seconds as a bulb check
each time the ignition key is
turned to RUN. If the light
doesn't turn on, have your
vehicle serviced.
If the engine oil is more than one quart (0.95 L) low and
the engine has been shut off for at least eight minutes,
the CHECK OIL LEVEL light will turn on for about
one minute and will then remain off until the next time
you start the vehicle.
If the CHECK OIL LEVEL light turns on, the engine oil
level should be checked at the dipstick then brought up
to the proper level, if necessary. See ªEngine Oilº in
the Index.
Low Washer Fluid Warning Light
This light will come on
when your windshield
washers are working and the
fluid container is less than
one
-third full.
Check Gages Warning Light (Option)
This light will come on
briefly when you are
starting the engine.
If the light comes on and stays on while you are driving,
check your gages for fuel, coolant temperature, oil
pressure or voltage. This light will stay on if your engine
is not running with the ignition on.

yellowblue
2-75 Check Doors Light
This light is part of the
Systems Monitor. This
message means that either
the driver's door or one of
the passenger's doors is not
completely closed.
Fuel Gage
Cluster with Gages Cluster with Compass
and GagesWhen the ignition is on, your fuel gage tells you about
how much fuel you have left. When the gage reads in
the yellow band, a warning chime will sound and the
CHECK GAGES warning light will go on, if you have
this option. This warning means you are low on fuel.
You should get more fuel as soon as you can.
Here are some things that some owners ask about. None
of these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads FULL (F).

It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank's capacity to fill
the tank.

The gage moves a little when you turn a corner,
speed up, or make a hard stop.

The gage doesn't go back to EMPTY (E) when you
turn off the ignition.

If you have the large span (220) gage, the needle
moves more for a given amount of fuel. This does
not indicate excessive fuel consumption, and
is normal.

yellowblue
2-76 Systems Monitor (Option)
If you have the Systems
Monitor, it gives you
important safety and
maintenance facts.
When you turn the ignition on, the Systems Monitor and
warning lights will briefly light up. If a problem is
detected, the warning lights will turn on.The following warning lights are displayed in the
Systems Monitor:

Check Oil Level: This message could mean your oil
level is low. If it comes on for more than three
seconds, see ªCheck Oil Level Warning Lightº in
the Index.

Washer Fluid: This message means your washer
fluid tank is less than about 30 percent full. If this
light comes on, see ªWindshield Washer Fluidº in
the Index.

Check Doors: This message means that either the
driver's door or one of the passenger's doors is not
completely closed. If this light comes on, see ªCheck
Doors Lightº in the Index.

Brake: If this message comes on while you are
driving, it means there is a brake problem. See
ªBrake System Warning Lightº in the Index.

yellowblue
2-77 Boost Gage (Option)
Vehicles equipped with the supercharged engine have
this boost gage that indicates vacuum during light to
moderate throttle and boost under heavier throttle. The
gage displays the air pressure level in psi going into the
engine's combustion chamber.
The gage is automatically centered at zero psi every
time the engine is started. Actual vacuum or boost is
displayed from this zero point. Changes in ambient
pressure, such as driving in mountains and changing
weather, will slightly change the zero reading.
Head-Up Display (Option)
CAUTION:
If the HUD image is too bright, or too high in
your field of view, it may take you more time to
see things you need to see when it's dark outside.
Be sure to keep the HUD image dim and placed
low in your field of view.
If you have the optional Head-Up Display (HUD), you
can see some of the driver information also available on
your instrument panel cluster. The information may be
displayed in English or metric units and appears as a
reflection on the windshield. The HUD shows:

Speedometer reading

Turn signal indicators

High
-beam indicator symbol

CHECK GAGES message (for low oil pressure, high
coolant temperature, low oil level and low fuel)

Low fuel warning symbol

yellowblue
2-78
HUD shows these images when they are lighted on the
instrument panel.
At 70 miles per hour (113 km/h), the speedometer may
display a variance of 3 miles per hour (5 km/h) from the
HUD. This condition is normal.When you sit straight in your seat, the HUD image will
appear slightly to the right.
When the ignition key is turned to RUN, all possible
HUD images will come on, then the Head
-Up Display
will operate normally.
If you never look at your instrument panel, you may not
see something important, such as a warning light. So be
sure to scan your displays and controls and the driving
environment just as you would in a vehicle without HUD.
NOTICE:
Although the HUD image appears to be near the
front of the vehicle, do not use it as a parking aid.
The HUD was not designed for that purpose. If
you try to use it that way, such as in a parking
lot, you may misjudge distance and run
into something.

FUNCTION MONITOR: This lets you know if
you are low on fluids or have a problem with a
vehicle function:

CHECK OIL LEVEL: This message could mean
your oil level is low. If it comes on for more than
three seconds, see ªCheck Oil Level Warning Lightº
in the Index.

WASHER FLUID: This message means your
washer fluid tank is less than about 30 percent full.
The windshield portion of the vehicle outline will
also glow. If these come on, see ªWindshield Washer
Fluidº in the Index.

LOW COOLANT: This message means your
coolant level has fallen to about half full. If it comes
on, see ªEngine Coolantº in the Index.

CHECK GAGES: If this light comes on and stays
on while you are driving, check your gages for fuel,
coolant temperature, oil pressure or battery voltage.
SECURITY MONITOR: The vehicle outline will
illuminate to let you know the following information:

DOOR AJAR: This message means a door is not
fully closed. The vehicle outline will show you
which door it is.
TRUNK AJAR: This message appears if the trunk is
not fully closed. The vehicle outline will illuminate.

HOOD AJAR: This message appears if the hood is
not fully closed. The vehicle outline will illuminate
if the hood is not latched properly.
LAMP MONITOR: Whenever you try to use one of
the following lamps, the LAMP MONITOR will tell you
if a bulb is out.

Headlamp (Low and High Beam)

Parking Lamp/Sidemarker

Turn Signal/Parking/Stop

Back
-Up Lamp

Taillamp/Turn/Sidemarker/License

Brake Lamp and Center High

LAMP, and you will also see where the problem is on
the vehicle outline. The message stays on until the
problem is fixed. See ªReplacement Bulbsº in the Index
for bulb details.
