Programming Delayed Locking
When your vehicle was shipped from the factory, the
delayed locking feature was programmed on, or
enabled. The mode may have been changed since it
left the factory. To turn the delayed locking feature on or
off, do the following:
1. Press and hold the power door lock switch on the
driver’s door in the lock position.
2. Press the remote keyless entry transmitter unlock
button twice.
If the delayed locking feature was on, it will now be off.
If the feature was off, it will now be on.
Programmable Automatic Door
Locks
Your vehicle is equipped with an automatic lock/unlock
feature which enables you to program your vehicle’s
power door locks. You can program this feature through
the Driver Information Center (DIC), or by the following
method.
Programmable Locking Feature
The following is the list of available programming
options:
Mode 1:All doors lock when the transmission is shifted
into gear.
Mode 2:All doors lock when the vehicle speed is
greater than 8 mph (13 km/h).
Mode 3:No automatic door locking.
The automatic door locks were pre-programmed at the
factory to lock all the doors when the transmission
is shifted into gear. The following instructions detail how
to program your door locks differently than the factory
setting. Choose one of the three programming
options listed above before entering the program mode.
To enter the program mode, do the following:
1. Begin with the ignition off. Then pull the turn
signal/multifunction lever toward you and hold
it there while you perform the next step.
2. Turn the key to RUN and LOCK twice. Then, with the
key in LOCK, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock, the horn will chirp twice, and a
30 second program timer will begin.

door lock switch to cycle through the unlocking
options. You will have 30 seconds to begin
programming. If you exceed the 30 second limit, the
locks will automatically lock and unlock and the
horn will chirp twice to indicate that you have left the
program mode. If this occurs, repeat the
procedure beginning with Step 1 to re-enter the
programming mode.You can exit the program mode any time by turning the
ignition to RUN. The locks will automatically lock and
unlock and the horn will chirp twice to indicate that you
are leaving the program mode. If the lock/unlock
switches are not pressed while in the programming
mode, the current auto lock/unlock setting will not be
modied.
See your dealer for more information.

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
Programming” later in this section.
4. The indicator light will ash slowly at rst and then
rapidly after HomeLink
®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
®button
and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink
®button is pressed and
released.
To program the remaining two HomeLink
®buttons,
begin with Step 2 under “Programming HomeLink®.”
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.
7. Firmly press and release the “Learn” or “Smart”
button. The name and color of the button may
vary by manufacturer.
You will have 30 seconds to start Step 8.
8. Return to the vehicle. Firmly press and hold the
programmed HomeLink
®button for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener (or other rolling
code device), repeat this sequence a third time
to complete the programming.
HomeLink
®should now activate your rolling-code
equipped device.
To program the remaining two HomeLink
®buttons,
begin with Step 2 of “Programming HomeLink®.” Do not
repeat Step 1.

Hazard Warning Flashers
Your hazard warning ashers let you warn others. They
also let police know you have a problem. Your front
and rear turn signal lamps will ash on and off.The button for the hazard
warning ashers is located
on top of the steering
column.
The hazard warning ashers work no matter what
position your key is in, and even if the key isn’t in.
Press the button all the way down to make your front
and rear turn signal lamps ash on and off. To turn
off the ashers, press the button again until it clicks and
then release it.
When the hazard warning ashers are on, the turn
signals won’t work.
Other Warning Devices
If you carry reective triangles, you can set one up at
the side of the road about 300 feet (100 m) behind your
vehicle.

Horn
To sound the horn, press the horn symbols on the
steering wheel pad.
Tilt Wheel
You should adjust the
steering wheel before you
drive. The tilt lever is
located to the left of the
steering column, under the
turn signal lever.
You can raise it to the highest level to give your legs
more room when you enter and exit the vehicle.
To tilt the wheel, hold the steering wheel and pull the
lever toward you. Move the steering wheel to a
comfortable level, then release the lever to lock the
wheel in place.
Do not adjust the steering wheel while driving.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
G:Turn and Lane Change Signals
2:Headlamp High/Low-Beam Changer
Flash-to-Pass Feature
N:Windshield Wipers
J:Windshield Washer
I:Cruise Control (If Equipped)
3-7

Turn and Lane Change Signals
The turn signal has two upward (for right) and two
downward (for left) positions. These positions allow you
to signal a turn or a lane change.
To signal a turn, move the lever all the way up or down.
When the turn is nished, the lever will return
automatically.
An arrow on the instrument
panel cluster will ash in
the direction of the
turn or lane change.
To signal a lane change, just raise or lower the lever
until the arrow starts to ash. Hold it there until you
complete your lane change. The lever will return by itself
when you release it. The bottom of the outside
rearview mirrors may also be equipped with lane change
indicators.As you signal a turn or a lane change, if the arrows
ash more quickly than normal, a signal bulb may
be burned out and other drivers won’t see your turn
signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows don’t go on at all when you signal
a turn, check the fuse. SeeFuses and Circuit Breakers
on page 5-101and check for burned-out bulbs.
If you have a trailer towing option with added wiring for
the trailer lamps, a different turn signal asher is
used. With this asher installed, the signal indicator will
ash even if a turn signal bulb is burned out. Check
the front and rear turn signal lamps regularly to make
sure they are working.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ash of the
turn signal. To turn off the chime, move the turn signal
lever to the off position.
