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 your vehicle is equipped with the Head-Up Display
(HUD), you can see some of the driver information that
appears on your instrument panel cluster.The information may be displayed in English or metric
units and appears as an image focused out toward the
front of your vehicle. The HUD consists of the
following information:

Speedometer

Turn Signal Indicators

High
-Beam Indicator Symbol

Tachometer

Oil, Temperature and Fuel Gages

Shift Light (Performance SHIFT Light)
This light is used for performance driving to indicate
that the vehicle's best performance level has been
reached to shift the transmission into the next higher
gear. The SHIFT light will display at an engine
speed of about 5,750 rpm, just prior to reaching the
engine fuel cut
-off mode. To better understand the
vehicle's power curves, see ªCapacities and
Specificationsº in the Index.

Be sure to continue scanning your displays, controls and
driving environment just as you would in a vehicle
without HUD. If you never look at your instrument
panel cluster, you may not see something important,
such as a warning light. Under important warning
conditions, the CHECK GAGES icon will illuminate in
the HUD. View your Driver Information Center (DIC)
for more information.

The HUD controls are located to the left of the
steering wheel.To adjust the HUD so you can see it properly:
1. Start your engine and slide the HUD dimmer control
all the way up.
The brightness of the HUD image is determined by
the light conditions in the direction your vehicle is
facing and where you have the HUD dimmer control
set. If you are facing a dark object or a heavily
shaded area, your HUD may anticipate that you are
entering a dark area and may begin to dim.
It is possible for sunlight to enter the HUD causing
all of the graphics to light up. The display will return
to normal when the sunlight is no longer entering
the HUD.
2. Adjust the seat to your driving position. If you
change your seat position later, you may have to
re
-adjust your HUD.
3. Press the DISPLAY switch up or down to center the
HUD image in your view.
The HUD image can only be adjusted up and down,
not side
-to-side.
4. Slide the dimmer control downward until the HUD
image is no brighter than necessary. To turn HUD
off, slide the switch to OFF.

2-116
If the sun comes out or it becomes cloudy, you may need
to adjust the HUD brightness again using the dimmer
control. Polarized sunglasses could make the HUD
image harder to see.
To change from English to metric units, push the
E/M button located to the right of the steering wheel.
Clean the inside of the windshield as needed to remove
any dirt or film that reduces the sharpness or clarity of
the HUD image.
To clean the HUD, 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 could leak into the unit.If the ignition is on and you can't see the HUD image,
check to see if:

Something is covering the HUD unit.

The HUD dimmer control is adjusted properly.

The HUD image is adjusted to the proper height.

Ambient light (in the direction your vehicle is
facing) is low.

A fuse is blown. See ªFuses and Circuit Breakersº in
the Index.
Keep in mind that your windshield is part of the HUD
system. If you ever have to have your windshield
replaced, be sure to get one that is designed for HUD or
your HUD image may look blurred and out of focus.

3-3
DEFOG: This setting divides the air between the
windshield and lower outlets with a small amount of air
directed toward the side window vents. This is useful
when fog appears on the windshield or side glass due to
rain or snowy conditions.
DEFROST: Use this setting to quickly remove fog
or frost from the windshield. This setting directs most of
the airflow to the windshield with a small amount of air
directed toward the lower and side window outlets.
Mode Buttons
These buttons control the air intake, the air conditioning
and the rear window defogger operation.
OUTSIDE AIR: Press this button and it
will bring outside air into the vehicle. The light on the
button will come on when operating. Use this setting
while trying to defrost or defog windows to help
clear moisture.
RECIRCULATE: Press this button to limit the
amount of outside air entering the vehicle by
recirculating most of the air inside the vehicle. The light
on the button will come on when operating. This setting
is helpful when you are trying to cool the air quickly or
to limit odors entering the vehicle. Recirculate cannot be
used while in the DEFROST or DEFOG modes.Operating the system in the recirculation mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
system to either the DEFOG or DEFROST mode and
increase the fan speed. To avoid re
-fogging of the
windows, operate the system in the OUTSIDE
AIR mode.
A/C: This button turns the air conditioning
compressor off or on under most conditions. The light
on the A/C button comes on when the compressor is
operating. The air conditioning does not operate at
temperatures below approximately 35
F to 40
F
(2
C to 4
C). The air conditioning cools and
dehumidifies the air coming into the vehicle. The air
conditioning cannot be turned off in DEFROST, as it
helps to remove moisture from the vehicle. It also helps
to keep the windows clear.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures.
See ªRear Window Defoggerº later in this section for
more information.

3-8
A/C: This button turns the air conditioning
compressor off or on under most conditions. The light
on the A/C button will come on when the compressor is
operating in either the automatic or manual mode. The
air conditioning does not operate at temperatures below
approximately 35
F to 40
F (2
C to 4
C). The light
on the A/C button will flash if pressed when air
conditioning is not available. The air conditioning cools
and dehumidifies the air coming into the vehicle. The air
conditioning cannot be turned off in DEFROST and
DEFOG, as it helps to remove moisture from the
vehicle. It also helps to keep the windows clear.
If the system is operating in the AUTO mode, turning
the air conditioning off will delete AUTO from the
digital display and show current mode and fan settings.
The AUTO button must be pressed to return to the
automatic mode operation.
The air conditioning may be forced off at high engine
speeds or high engine oil or coolant temperatures. OUTSIDE AIR: Press this button to provide
outside air. The light on this air intake button will come
on to show when it is operating. When in the AUTO
mode, the system automatically selects OUTSIDE AIR
instead of recirculate, as required, to control the
temperature in the vehicle. By pressing OUTSIDE AIR,
the system will lock into the outside air mode. Any
adjustment to the air intake must then be made
manually. OUTSIDE AIR should be used when trying to
defrost or defog windows to help reduce moisture inside
of the vehicle.
RECIRCULATE: Press this button to limit the
amount of outside air entering the vehicle. The light on
this air intake button will come on to show when it is
operating. Recirculate is helpful when you are trying to
cool the air quickly or trying to limit odors and dust
from entering the vehicle. When in the AUTO mode,
the system automatically selects recirculate to cool the
vehicle's temperature. By pressing this button, the
system will lock into the recirculated air mode.
Any adjustment to the air intake must then be made
manually. Recirculation is not available when using the
defrost or defog mode because outside air is need to
reduce moisture inside of the vehicle.
