Malfunction Indicator Lamp
(Service Engine Soon 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 SERVICE ENGINE SOON 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, transaxle,
exhaust, intake 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 SERVICE ENGINE SOON
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.

2-83 Oil Pressure Gage
United States Canada
Readings above the red warning zone indicate the
normal operating range. Oil pressure may vary with
engine speed, outside temperature and oil viscosity.
A reading in the red warning zone may be caused by a
low oil level or another problem causing low oil
pressure. On vehicles with the systems monitor, the
CHECK GAGES light will come on and a warning
chime will sound.On vehicles with a DIC, a CHECK GAGES OIL
PRESSURE message will be displayed and a warning
chime will sound. See ªDIC Warnings and Messagesº in
the Index for more information.
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.

Fuel Gage
United States Canada
When the ignition is on, your fuel gage tells you about
how much fuel you have in your tank.

2-87
When the gage reads in the yellow band, a warning
chime will sound and the CHECK GAGES warning
light will come on. You still have a little fuel left, but
you need to get more fuel right away.
On vehicles with a DIC, the CHECK GAGES LOW
FUEL message will be displayed when the fuel gage
reads in the yellow band. See ªDIC Warnings and
Messagesº in the Index for more information.
Here are some things that 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.

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.Boost Gage (If Equipped)
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 going into the
engine's combustion chamber.
The gage is automatically centered at zero every time
the ignition key is turned to ON. 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.

2-88
Systems Monitor (If Equipped)
If you have the systems
monitor, it gives you
important safety and
maintenance facts about
your vehicle.

detected, the warning lights will turn on and a chime
will sound.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
five seconds, see ªCheck Oil Level Warning Lightº

gages may be in their respective warning bands. If
this light comes on, see ªCheck Gages Warning
Lightº in the Index.

TRUNK AJAR: This message means your trunk is
not completely closed.

2-104
HUD shows these images when they are lighted on the
instrument panel.
The speedometer may display a difference of 1.5 mph
(2.4 km/h) from the HUD image. This is normal.
When the ignition key is turned to ON, all possible
HUD images will come on, then the HUD will
operate normally.If you never look at your instrument panel cluster, 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.
