Ignition Positions
With your key in the ignition switch you can turn it to
four different positions.
A (LOCK):This position locks your ignition and
transmission. It's a theft-deterrent feature. You will only
be able to remove your key when the ignition is
turned to LOCK.
Notice:If your key seems stuck in LOCK and you
can not turn it, be sure you are using the correct
key; if so, is it all the way in? Turn the key only with
your hand. Using a tool to force it could break the
key or the ignition switch. If none of these works,
then your vehicle needs service.
B (ACCESSORY):This position allows you to use
things like the radio, power windows and the windshield
wipers when the engine is off.
C (RUN):This position is for driving.
D (START):This position starts your engine.
Retained Accessory Power (RAP)
The Retained Accessory Power (RAP) feature will
allow certain features on your vehicle to continue to work
for up to 10 minutes after the ignition key is turned
to LOCK.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position ± that's a
safety feature. To restart when you're already moving,
use NEUTRAL (N) only.

Programming the HomeLinkž
Transmitter
Do not use the HomeLinkžTransmitter with any garage
door opener that does not have the ªstop and reverseº
feature. This includes any garage door opener model
manufactured before April 1, 1982. If you have a newer
garage door opener with rolling codes, please be
sure to follow steps 6 through 8 to complete the
programming of your HomeLink
žTransmitter.
Read the instructions completely before attempting to
program the HomeLink
žTransmitter. Because of the
steps involved, it may be helpful to have another person
available to assist you in programming the transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
žprogramming. It is also
recommended that upon the sale of the vehicle, the
programmed HomeLink
žbuttons should be erased for
security purposes. Refer to ªErasing HomeLinkžButtonsº
or, for assistance, contact HomeLinkžon the internet at:
www.homelink.com or by calling 1-800-355-3515.
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
¯ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
žbuttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
ž
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
žand 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 ªGate Operator and Canadian
Programmingº later in this section.
4. The indicator light will ¯ash slowly at ®rst and then
rapidly after HomeLink
žsuccessfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to ªtime outº or quit after several seconds of
transmission. This may not be long enough for
HomeLink
žto pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
ªtime outº in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
ªProgramming HomeLink
žº procedures (regardless of
where you live), replace Step 3 under ªProgramming
HomeLink
žº with the following:
Continue to press and hold the HomeLink
žbutton while
you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal has
been successfully accepted by HomeLink
ž. The
indicator light will ¯ash slowly at ®rst and then rapidly.
Proceed with Step 4 under ªProgramming HomeLink
žº
to complete.
Using HomeLinkž
Press and hold the appropriate HomeLinkžbutton for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLinkžButtons
To erase programming from the three buttons do the
following:
1. Press and hold down the two outside buttons until
the indicator light begins to ¯ash, after 20 seconds.
2. Release both buttons. Do not hold for longer than
30 seconds.
HomeLink
žis now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under ªProgramming HomeLink
ž.º
Individual buttons can not be erased, but they can be
reprogrammed. See ªReprogramming a Single
HomeLink
žButtonº next.

If a hand, arm, or other object is blocking the sunroof
glass panel as it is closing, the glass panel will stop
at the obstruction. After the obstruction is removed, the
glass panel can be closed or opened.
Use care not to leave the sunroof open for long periods
of time as debris may collect in the tracks.
If the battery has been recharged, disconnected or is
not working, you may need to reprogram the sunroof. To
do this, start the vehicle and press the forward side of
the sunroof button until the glass panel moves to a fully
closed position. Release, and press again to move to
the vent position which occurs when the sunroof is fully
tilted rearward. This will reset the memory and enable
the sunroof to function properly.Vehicle Personalization
Memory Seat
If your vehicle has this
feature, then the controls
for the memory function
are located on the driver's
door.
These buttons are used to program and recall memory
settings for the driver's seat, throttle and brake
pedals, both the driver's and passenger's outside mirror,
and the radio station presets. The settings for these
features can be personalized for both driver 1 and
driver 2. Driver 1 or driver 2 corresponds to the memory
buttons labeled 1and 2 on the driver's door.

To store your memory seat, throttle and brake pedals,
mirrors and radio presets, do the following:
1. Adjust the driver's seat (including the seatback
recliner, lumbar, and side wing area), throttle
and brake pedals, both of the outside mirrors, and
the radio station presets to your preference.
2. Press and hold the 1 or 2 (for driver 1or 2) button
of the memory control for three seconds. A double
chime will sound to let you know that the position
has been stored.
To repeat the procedure for a second driver, follow the
preceding steps, but press the other numbered
memory control button.
Each time button 1 or 2 is pressed and released while
the vehicle is in PARK (P), a single chime will sound and
the memory position will be recalled.If you use the unlock button on the remote keyless entry
transmitter to enter your vehicle, the preset driver's
seat, throttle and brake pedal, mirror positions and the
radio station presets will be recalled if programmed
to do so through the Driver Information Center (DIC).
The numbers on the back of the transmitters, 1 or 2,
correspond to the numbers on the memory controls.
The seat, throttle and brake pedals and mirror positions
can also be recalled when placing the key in the
ignition if programmed to do so through the Driver
Information Center (DIC).
To stop recall movement of the memory seat feature at
any time, press one of the memory buttons or power
seat controls.
