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.

2-79
The HUD controls are located to the left of the
steering column.
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
whether the headlamp switch is on or off, and where you
have set the HUD dimmer control.2. Adjust the seat, if necessary, before setting the
height control.
Slide the IMAGE (image height) control all the way up,
raising the image as far as possible. Then slide the HUD
image height control down so the image is as low as
possible but in full view.
3. Slide the dimmer control downward until the HUD
image is no brighter than necessary. To turn the HUD
off, slide the HUD dimmer control all the way down.
If the sun comes out, or it becomes cloudy, or if you turn
on your headlamps, you may need to adjust the HUD
brightness using the HUD dimmer control. Polaroid
sunglasses could make the HUD image harder to see.
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity of
the HUD image.
Spray household glass cleaner on a soft, clean cloth.
Wipe the HUD lens gently, then dry it. Do not spray
cleaner directly on the lens, because the cleaner fluid
could leak inside the unit if you do.

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

The headlamps are on

The HUD unit is covered

The HUD dimmer control is adjusted correctly

The HUD image is adjusted to the proper height

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.Driver Information Center (Option)
If you have the Driver Information Center (DIC), it
gives you important safety and maintenance facts. When
you turn the ignition on, the entire center lights up for a
few seconds. Then it goes to work.

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.

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

Electronic Compass (Option)
Some vehicles are equipped with an electronic compass.
As with all compasses, this unit senses the earth's
magnetic field to show the direction the car is pointing.

yellowblue
2-83
The earth's magnetic field is not always the same
direction as true north as we know it. So, you must enter
a zone number to tell the compass the difference
between magnetic and actual north. This tells the
compass where in the country you are driving.
The compass shows the zone number in use each time
you turn your key on. This is above the compass. The
number is turned off after a few seconds.
The compass remembers your zone, so you only have to
change it if you drive to a new zone on the map. The
compass adjusts only a small amount for each zone, so
you may not notice a difference if you drive from one
zone to the next one, until you cross several zones.Choosing Your Zone Number
Locate your zone number on the previous map. If your
number is different than the one shown when you turn
the key on, follow the steps to change your
zone number.
If you live on the line, you can pick the zone area you
are most likely to drive in. (In Alaska use Zone 9 or 10.
In Hawaii use Zone 7).

Changing Your Zone Number
1. Press and hold the MODE button until zone and the
zone number appear.
2. Release the MODE button.
3. Press the MODE button until your number appears.
4. In a few seconds, the zone number and ZONE turn
off, and the new zone number is remembered by
the compass.Calibrating the CompassAll electronic compasses need to know the magnetic
profile of your car. This is called calibration and is done
automatically by your compass. But, the feature is
available if you would like to manually calibrate.
