Anti-Lock Brake System Warning Light
United States Canada
With the anti
-lock brake system, the light(s) will come
on when you turn the key to RUN and may stay on for
five seconds. That's normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you're driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while you're driving, your vehicle needs
service. If the regular brake system warning light isn't
on, you still have brakes, but you don't have anti
-lock
brakes. If the regular brake system warning light is also
on, you don't have anti
-lock brakes and there's a
problem with your regular brakes. See ªBrake System
Warning Lightº earlier in this section.The anti
-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
Traction Control System Warning
Light (Option)
This warning light should
come on briefly as you start
the engine.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem.
If it stays on, or comes on when you're driving, there
may be a problem with your traction control system and
your vehicle may need service. When this warning light
is on, the system will not limit wheel spin. Adjust your
driving accordingly.

2-71 Tire Pressure Light (If Equipped)
The check tire pressure
system can alert you to
a large change in the
pressure of one tire.
After the system has been properly calibrated, the
TIRE PRESS light will come on if a pressure difference
(low pressure) is detected in one tire.
The light will stay on until you turn off the ignition or
reset (calibrate) the system. See ªCheck Tire Pressure
Systemº in the Index.
The TIRE PRESS light also comes on briefly when you
turn your ignition key to START. If the light doesn't
come on then, have it fixed so it will be there to tell you
if the pressure in a tire is low.
If the anti
-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. (Also, see
ªAnti
-Lock Brake System Warning Lightº in the Index).
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.

2-72
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 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.
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.

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

2-79 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 RUN. 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, high/low
battery, brake, ABS and air bag.)

Low Fuel Warning Symbol

Radio Frequency and Playback Mode

2-80
HUD shows these images when they are lighted on the
instrument panel.
The speedometer may display a difference of 1 mph
(1.6 km/h) from the HUD image. This is normal.
When the ignition key is turned to RUN, 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.

2-82
If you can't see the HUD image when the ignition is on,
check to see if:

The HUD unit is covered,

the HUD dimmer control is adjusted correctly,

the HUD image is adjusted to the proper height, or

a fuse in the fuse panel may be blown. See ªFuses
and Circuit Breakersº in the Index.
If the HUD image is not clear, it could be too bright.
Move the HUD dimmer control further downward.
You may need to clean the windshield and HUD lens.
Your windshield is part of the HUD system. If you ever
have to have a new windshield, be sure to get one
designed for HUD. If you don't, the HUD image may
look blurred and out of focus.Systems Monitor (If Equipped)
If you have the systems
monitor, it gives you
important safety and
maintenance facts about
your vehicle.
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 and a chime
will sound.
