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. SeeDIC Vehicle Customization on page 3-57.
Programmable Locking Feature
Following are the two locking modes that can be
programmed:
Mode 1:All doors lock when the transmission is shifted
out of PARK (P).
Mode 2:All doors lock when the vehicle speed is
greater than 8 mph (13 km/h).
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 two 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.
3. You are now ready to program the automatic door
locks. Select one of the two programming options
listed above, and press the lock side of the power
door lock switch to cycle through the lock 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.

Programmable Unlocking Feature
The following is the list of available programming options:
Mode 1:All doors unlock when the transmission is
shifted into PARK (P).
Mode 2:Driver’s door unlocks when the transmission is
shifted into PARK (P).
Mode 3:All doors unlock when the key is removed
from the ignition.
Mode 4:No automatic door unlock.
The automatic door locks were pre-programmed at the
factory to unlock all doors once the transmission is shifted
to PARK (P). The following instructions detail how to
program your door locks differently than the factory
setting. Choose one of the four programming options
listed above before entering the program mode.
To enter the program mode you need to 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.
3. You are now ready to program the automatic door
locks. Select one of the four programming options
listed above, and press the unlock side of the
power 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.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located on the driver’s side of the
engine compartment, behind the battery.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet
could cause an electrical shock. Also, the
wrong kind of extension cord could overheat
and cause a re. You could be seriously
injured. Plug the cord into a properly grounded
three-prong 110-volt AC outlet. If the cord will
not reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts. If you do not, it could
be damaged.How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature,
the kind of oil you have, and some other things.
Instead of trying to list everything here, we ask that
you contact your dealer in the area where you will be
parking your vehicle. The dealer can give you the
best advice for that particular area.
Displacement on Demand (DoD)
Your vehicle’s engine may be equipped with
Displacement on Demand (DoD). This system allows
the engine to operate on either four or eight cylinders,
depending on your driving demands.
The system determines when to switch into and out of
the four-cylinder mode by rst making sure that
certain enabling criteria are met, such as coolant and
oil temperatures, and the transmission being in
either THIRD (3) or FOURTH (4) gear.
When greater power demands are required, such as
accelerating from a stop, passing, or merging onto
a freeway, the system will maintain eight-cylinder
operation. When less power is required, such a
cruising at a constant vehicle speed, the system will
automatically enable the four-cylinder mode, allowing
your vehicle to achieve better fuel economy.

Four-Wheel Drive
If your vehicle has four-wheel drive, you can send your
engine’s driving power to all four wheels for extra
traction. To get the most satisfaction out of four-wheel
drive, you must be familiar with its operation. Read the
part that follows before using four-wheel drive.
You should use two-wheel drive high (2HI) for most
normal driving conditions.
Notice:Driving on clean, dry pavement in
four-wheel drive for an extended period of time may
cause premature wear on your vehicle’s powertrain.
Do not drive on clean, dry pavement in four-wheel
drive for extended periods of time.
Automatic Transfer Case
If your vehicle is equipped
with four-wheel drive,
the transfer case knob is
located to the right of the
steering wheel on the
instrument panel. Use this
knob to shift into and out of
four-wheel drive.2HI (Two-Wheel High):This setting is for driving in
most street and highway situations. Your front axle is not
engaged in two-wheel drive. It also provides the best
fuel economy.
A4WD (Automatic Four-Wheel Drive):This setting
is ideal for use when road conditions are variable.
When driving your vehicle in A4WD, the front axle is
engaged, but the vehicle’s power is sent to the rear
wheels. When the vehicle senses a loss of traction,
the system will automatically engage four-wheel drive.
Driving in this mode results in slightly lower fuel
economy than 2HI.
4HI (Four-Wheel High):Use 4HI when you need extra
traction, such as on snowy or icy roads or in most
off-road situations. This setting also engages your front
axle to help drive your vehicle.
4LO (Four-Wheel Low):This setting also engages
your front axle and delivers extra torque. It sends
maximum power to all four wheels. You might choose
4LO if you are driving off-road in deep sand, deep mud,
and climbing or descending steep hills.

Compass Display
O
(On/Off):Press this button to turn the compass on
or off. The compass display, can show a maximum
of two characters. For example, NE is displayed
for north-east.
When the ignition and the compass/temperature feature
are on, character boxes will appear for about two
seconds. After two seconds, the mirror will display the
direction the vehicle is facing.
Compass Calibration
When on, the compass automatically calibrates as the
vehicle is driven. If, after two seconds, the display
does not show a compass direction, (N for North,
for example), there may be a strong magnetic eld
interfering with the compass. Such interference may be
caused by a magnetic antenna mount, magnetic
note pad holder, or a similar magnetic item. If the
letter C should ever appear in the compass window,
the compass may need calibration.Press and hold the on/off button for nine seconds to
activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display shows
a direction.
Compass Variance
Compass variance is the difference between
earth’s magnetic north and true geographic north.
The mirror is set to zone eight upon leaving the
factory. It will be necessary to adjust the compass to
compensate for compass variance if you live outside
zone eight. Under certain conditions, such as during a
long-distance, cross-country trip, it will be necessary
to adjust for compass variance. If not adjusted to
account for compass variance, the compass could
give false readings.

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. 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
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. 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
®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 HomeLink®on 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.
Programming HomeLink®
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
®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.

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to “time out” or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
“time out” in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator by using the
“Programming HomeLink
®” procedures (regardless of
where you live), replace Step 3 under “Programming
HomeLink
®” with the following:
Continue to press and hold the HomeLink
®button
while you press and release every two seconds (cycle)
your hand-held transmitter until the frequency signal
has been successfully accepted by HomeLink
®.
The indicator light will ash slowly at rst and then
rapidly. Proceed with Step 4 under “Programming
HomeLink
®” to complete.
Using HomeLink®
Press and hold the appropriate HomeLink®button for
at least half of a second. The indicator light will come on
while the signal is being transmitted.
Erasing HomeLink®Buttons
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.
Do not hold the two outside buttons for longer
than 30 seconds.
2. Release both buttons.
HomeLink
®is now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under “Programming HomeLink
®” shown earlier in
this section.
Individual buttons cannot be erased, but they can be
reprogrammed. See “Reprogramming a Single
HomeLink
®Button” following this section.
