Vehicle Programming and
Personalization Features
Your vehicle is equipped with personalization that
allows you to program certain features to a preferred
setting for up to two people. The number of
programmable features varies depending upon which
model of the vehicle is purchased.
On all vehicles, features such as climate control settings,
radio preset settings, exterior lighting at unlock, remote
lock and unlock confirmation, and automatic door locks
have already been programmed for your convenience.
Some vehicles are equipped with additional features that
can be programmed including the seat and outside
rearview mirror position. The optional navigation
system screen preferences will remain at the last set
position.
If your vehicle is equipped with the ability to program
additional personalization features, the driver's
preferences are recalled by pressing the unlock button
on the remote keyless entry transmitter, 1 or 2, or
by pressing the appropriate memory button, 1 or 2,
located on the driver's door. Certain features can be
programmed not to recall until the key is placed in the
ignition. To change feature preferences you must use
one of the following procedures.
Entering the Personalization Menu
To enter the feature programming mode, use one of the
following procedures:
Base Audio System
1. Turn the ignition to ON, but do not start the engine.
Make sure an automatic transmission is in PARK (P)
or a manual transmission has the parking brake set.
2. If your vehicle has memory settings, press the
appropriate memory button, 1 or 2, located on the driver's
door armrest. The DIC display will show either Driver 1
or 2 depending on which button was selected.
3. Press the TUNE/SEL knob once to access the main
menu of the DIC.
4. Turn the TUNE/SEL knob until SETUP is highlighted.
5. Press the TUNE/SEL knob once to access the
SETUP menu.
6. Scroll to the feature you want to change, and press
the TUNE/SEL knob to turn the feature on or off.
If the feature is turned on, a check mark will appear
next to the feature name.
If none of the personalization items are turned on,
turn on the personalization menu by pressing the
TUNE/SEL knob. The list of features will then
appear, and you can repeat Step 6.

Navigation System
1. Turn the ignition to ON without the engine running.
Make sure an automatic transmission is in PARK (P)
or a manual transmission has the parking brake set.
2. Turn on the Navigation/audio system by pressing the
PWR/VOL knob located to the lower left of the
display once.
3. Access the DIC main menu by pressing the MAIN
button located to the lower left of the display.
4. Press the multi
-function button next to Feat Prog to
access the Feature Programming menu.
5. Press the TUNE/SEL knob to turn on the
Personalization features. An X will appear in the box
to the left when Personalization is turned on.
Personalization Features
The following choices are available for programming
using both the Base audio and Navigation systems
unless otherwise indicated.
Personalization Name
This feature allows you to type in a name that will
appear on the DIC display whenever the corresponding
remote keyless entry transmitter is used or one of the
buttons on the driver's door armrest (1 or 2) is pressed.
If a customized name is not programmed, the system
will show Driver 1 or Driver 2 to correspond with the
numbers on the back of the remote keyless entry
transmitters.
To program a name, use one of the following
procedures:

3-4
(Passenger's Temperature Switch): This switch is
used to increase or decrease the temperature of the air
for the passengers independent of the driver's setting.
To turn the system on, press the PWR button located
on the passenger's side of the climate control panel.
To adjust the temperature, press the up or down arrow
on the PWR button. The temperature will increase or
decrease with each press of an arrow.
If the passenger's temperature switch is off, the driver's
temperature switch controls the temperature for the
entire vehicle.
The passenger's side temperature is only displayed
when the passenger's side temperature switch is on.
Automatic Operation
AUTO (Automatic Climate Control): This button is
used to select the automatic operation of the climate
control system. When the automatic operation is active,
AUTO will appear next to the fan and mode settings on
the display.There are three sensors in the climate control system.
One monitors the sun's solar radiation, another monitors
temperature of the air inside the vehicle, and a third
monitors the temperature outside the vehicle. The
climate control system will vary the fan speed, air
delivery mode and use of the air conditioning
compressor to maintain the set temperature based on the
information received from these sensors. See ªDriver's
Temperature Switchº and ªPassenger's Temperature
Switchº listed previously for more information on
setting a temperature.
To find your comfort zone, start with the 75
F (24
C)
setting and allow approximately 10 to 30 minutes for the
system to regulate. Adjust the temperature if necessary.
If you choose either the lowest temperature setting,
60
F (16
C), or the highest temperature setting,
90
F (32
C), the system will not cool or heat any
faster, but the system will stay at that setting without
regulating fan speed.
To avoid blowing cold air in cold weather, the system
will start at lower fan speeds until warm air is available.
The length of reduction depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started. As the engine coolant
warms up, the fan speed will gradually increase.

3-9 Climate Control Steering Wheel Controls
There are four controls that can be programmed for use
with the climate control system.
The controls are located
on the left spoke of the
steering wheel.
See ªReconfigurable Steering Wheel Controlsº in
the Index for more information on programming
these controls.
Audio Systems
Your audio system has been designed to operate easily
and to 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.

3-30 Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to it.
To help avoid hearing loss or damage do the following:
1. Adjust the volume control to the lowest setting.
2. Increase volume slowly until you hear comfortably
and clearly.NOTICE:
Before you add any sound equipment to your
vehicle
-- like a tape player, CB radio, mobile
telephone or two
-way radio -- be sure you can
add what you want. If you can, it's very
important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle's engine, radio or other systems, and
even damage them. Your vehicle's systems may
also interfere with the operation of sound
equipment that has been added improperly.
So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.

4-7
Avoid needless heavy braking. Some people drive in
spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the
traffic and allow realistic following distances, you will
eliminate a lot of unnecessary braking. That means
better braking and longer brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist. But
you will use it when you brake. Once the power assist is
used up, it may take longer to stop and the brake pedal
will be harder to push.
Anti-Lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with the
anti
-lock brake system, this
warning light will stay on.
See ªAnti
-Lock Brake
System Warning Lightº in
the Index.
