2-118
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.

3-4 Automatic Electronic Dual Climate Control
System (Option)
Your vehicle may be equipped with an automatic
electronic dual climate control system. This system can
automatically adjust and control temperature output, fan
speed, air delivery mode, air conditioning operation and
air intake. You can use the AUTO (automatic) setting or
override the automatic operation with manual control
settings. The set temperature will be remembered each
time you turn the ignition off and restart in the same
settings. You can use the memory option to recall your
settings. SeeªMemoryº in the Index.Digital Display
The digital display shows readings in Fahrenheit or
Celsius by pressing the E/M button (English/Metric)
on the Driver Information Center (DIC). When you
start the vehicle, the display will show the current fan
speed, air delivery mode and the driver
-set temperature
for approximately five seconds and then show the
outside temperature.
When the system is fully in the automatic mode, the
word AUTO will also appear on the display unless you
are in full cold 60
F (16
C) or full hot 90
F (32
C),
then the word AUTO will not display. If you have
selected a manual fan speed, then the fan symbol will
appear on the display. If a manual air delivery mode has
been selected, the delivery mode symbol will appear on
the display.

3-10 Sensors
The automatic electronic dual climate control system
uses several sensors to control operation and
display information.
Solar Load Sensor
This sensor is located on the top right side of the
defroster grille. The defroster grille is on the top of
the instrument panel.
The sensor monitors the sun's solar radiation and uses
this information as part of the automatic climate control
system when operating in the AUTO mode.
Be careful not to put anything over the sensor. When
covered, the sensor cannot compensate for changes in
the amount of heat the vehicle is absorbing from the sun.
Outside Air Temperature Sensor
This sensor is located in the air intake under the front
bumper of the vehicle. Information from this sensor is
used for the outside air temperature readings shown on the
digital display for the automatic climate control system.If the outside temperature goes up, the displayed
temperature will not change until:

The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.

The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays help prevent false readings. If the
temperature goes down, the outside temperature
display is updated immediately.
If the vehicle has been turned off for more than three
hours, the current outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
Inside Temperature Sensor
This sensor is located to the left of the ignition switch.
The automatic climate control system uses this sensor
to receive information, so if you block or cover it,
the system will not function properly.

3-13 Ventilation System
Your vehicle's flow-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the fan is running.
Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

When you enter a vehicle in cold weather, turn the
fan to the highest speed for a few moments before
driving off. This helps clear the intake outlets of
snow and moisture, and reduces the chance of
fogging the inside of the windows.

Keep the area around the base of the center
instrument panel console and air path under the seats
clear of objects. This helps air circulate throughout
the vehicle.
Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off. See
ªRetained Accessory Powerº in the Index.
Setting the Clock
Press and hold HR until the correct hour appears.
Press and hold MN until the correct minute appears.

your audio system adjusts automatically to make up for
road and wind noise as you drive. Set the volume at the
desired level. Turn the control ring behind the upper
knob clockwise to adjust the SCV. Each notch on the
control ring allows for more volume compensation
at faster vehicle speeds. Then, as you drive, SCV
automatically increases the volume, as necessary, to
overcome noise at any speed. The volume level should
always sound the same to you as you drive. If you don't
want to use SCV, turn the control all the way down.

up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this
player. If a tape is inserted when the ignition is on but
the radio is off, the tape will begin playing. A tape
symbol is shown in the center of the graphic display
whenever a tape is inserted. When a tape is active, the
tape symbol will be accompanied by a direction arrow.
