Programmable Automatic
Door Locks
Your vehicle is equipped with an auto IocWunlock
feature which enables you
to program your power
door locks.
Your vehicle left the factory programmed to have all the
doors lock automatically when the shift lever is moved out
of PARK (P).
All of the doors will unlock when the shift
lever is moved back into PARK (P). The following
instructions detail how to program your door locks. To
enter the program mode you need to do the following:
1. Begin with the ignition in OFF. Then, pull back on the
turn signaVmultifunction lever all the way toward you
and hold
it while you perform the next step.
2. Turn your key to RUN and
OFF twice. Then, with
the key in
OFF, release the turn signaVmultifunction
lever. Once you do this, you will hear the lock
switch lock and unlock.
You are now ready to program the automatic door
locks. Select one
of the following four programming
options and follow the instructions. You
will have thirty
seconds to begin programming.
If you exceed the
thirty second limit, the locks will automatically lock and
unlock to indicate that you have left the program mode.
If this occurs, repeat the procedure beginning with
Step
1. You can exit the program mode any time by
turning the ignition to RUN. The locks will automatically
lock and unlock
to indicate that you are leaving the
program mode. If the IocWunlock switches are not
pressed while in the programming mode, the auto

If you manually select SECOND (2), the transmission
will drive in second gear. You may use this feature
for reducing torque to the rear wheels when you
are trying to start your vehicle from a stop on slippery
road surfaces.
FIRST (1): This position gives you even more power
(but lower fuel economy) than
SECOND (2). You can
use it on very steep hills, or in deep snow or mud.
If the
shift selector lever is put in FIRST
(I), the transmission
won’t shift into first gear until the vehicle is going
slow enough.
Notice: If your rear wheels won’t turn, don’t try
to drive. This might happen if you were stuck in
very deep sand or mud or were
up against a solid
object. You could damage your transmission.
Also, if you stop when going uphill, don’t hold
your vehicle there with only the accelerator pedal.
This could overheat and damage the transmission. Use your brakes or shift into
PARK (P) to hold
your vehicle in position on a hill.

Programming the HomeLink
Transmitter
Do not use the HomeLink@ Transmitter with any garage
door opener that does not have the “stop and reverse”
feature. This includes any garage door opener model
manufactured before April
1, 1982.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink@ programming. It is also
recommended that upon the sale of the vehicle, the
programmed HomeLink@ buttons should be erased for
security purposes. Refer to “Erasing HomeLink@ Buttons”
or, for assistance, contact HomeLinkO on the internet at:
www.home1ink.com or by calling 1-800-355-351 5.
Be sure that people and objects are clear of the
garage door or gate operator you are programming.
When programming a garage door, it is advised to park
outside of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency. Your
vehicle’s engine should be turned
off while
programming the transmitter. Follow these steps
to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins
to
flash, after 20 seconds. Do not hold down the
buttons for longer than

repeat this step
to program a second and/or third
transmitter to the remaining two HomeLink@ buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink@
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink@ and the hand-held transmitter
button.
Do not release the buttons until Step 4
has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian

allows you
to switch the display between the English and
metric system.
MODE: The MODE button can be used to toggle
between three modes of operation:
OFF, COMP/TEMP
and TRIP.
COMPTTEMP (CompassTTemperature): This display
provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle
is facing.
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on.
If the outside
temperature
is 37°F (3°C) or lower, the display will
toggle between the word ICE and the current
temperature every eight seconds. This is a warning
to
the driver that road conditions may be icy, and that
appropriate precautions should be taken.

times at a speed of less than 5 mph
(8 km/h), and the
compass will function normally. Once the calibration
is
complete, the display will return to a compass reading.
Variance is the difference between magnetic north
and geographic north. In some areas, the difference
between the two can be great enough
to cause false
compass readings.

Audio System(s)
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, Delphi Electronics radio or other systems, and even damage
them. Your vehicle’s systems may 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.
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 may have a feature called Retained
Accessory Power (RAP). With RAP, you can play
