6. Turn the transfer case dial clockwise to
NEUTRAL till it stops and hold it for
10 seconds. Then slowly release the dial to
the four low position. The NEUTRAL light will
come on when the transfer case shift to
NEUTRAL is complete.
7. If the engine is running, verify that the
transmission is in NEUTRAL (N) by shifting the
transmission to REVERSE (R) for one second,
then shift the transmission to DRIVE (D) for
one second.
8. Turn the ignition to ACCESSORY, which will
turn the engine off.
9. Place the transmission shift lever in PARK (P).
10. Release the parking brake prior to moving
the vehicle.

NEUTRAL the NEUTRAL light will go out.
4. Release the parking brake prior to moving the
vehicle.
Notice:Shifting the transmission into gear
before the Four-Wheel Drive Low indicator light
has stopped ashing could damage the
transfer case. To help avoid damaging your
vehicle, always wait for the Four-Wheel
Drive Low indicator light to stop ashing
before shifting the transmission into gear.
5. Start the engine and shift the transmission to
the desired position.
Excessively shifting the transfer case into or out of
the different modes may cause the transfer
case to enter the shift protection mode. This will
protect the transfer case from possible damage
and will only allow the transfer case to respond to
one shift per 10 seconds. The transfer case
may stay in this mode for up to three minutes.

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 Universal Home Remote 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 or garage door
opener by using the “Programming Universal
Home Remote” procedures, regardless of where
you live, replace Step 3 under “Programming
Universal Home Remote” with the following:
Continue to press and hold the Universal Home
Remote button while you press and release every
two seconds (cycle) the hand-held transmitter
button until the frequency signal has been
successfully accepted by the Universal Home
Remote. The Universal Home Remote indicator
light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming
Universal Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home
Remote button for at least half of a second.
The indicator light will come on while the signal is
being transmitted.
Erasing Universal Home Remote
Buttons
To erase programming from the three Universal
Home Remote 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.
The Universal Home Remote is now in the training
(learning) mode and can be programmed at any
time beginning with Step 2 under “Programming
Universal Home Remote” shown earlier in
this section.
Individual buttons cannot be erased, but they can
be reprogrammed. See “Reprogramming a
Single Universal Home Remote Button” following
this section.

Do not use this system 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.
Read the instructions completely before attempting
to program the transmitter. Because of the steps
involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Be sure to keep the original remote control
transmitter for use in other vehicles, as well as, for
future programming. You only need the original
remote control transmitter for Fixed Code
programming. It is also recommended that upon
the sale or lease termination of the vehicle,
the programmed buttons should be erased for
security purposes. See “Erasing Universal Home
Remote Buttons” later in this section.When programming a garage door, it is advised to
park outside of the garage. Be sure that people
and objects are clear of the garage door or
security device you are programming.
Programming Universal Home
Remote — Rolling Code
Most garage door openers sold after 1996 are
Rolling Code units.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these
actions, the device will time out and you will have
to repeat the procedure.

Your panel of switches may not appear
exactly as they do in the examples above, but
they should be similar.
The switch positions on your hand-held
transmitter may be labeled, as follows:
A switch in the up position may be labeled
as “Up,” “+,” or “On.”
A switch in the down position may be
labeled as “Down,” “−,” or “Off.”
A switch in the middle position may be
labeled as “Middle,” “0,” or “Neutral.”2. Write down the eight to 12 switch settings
from left to right as follows:
When a switch is in the up position,
write “Left.”
When a switch is in the down position, write
“Right.”
If a switch is set between the up and down
position, write “Middle.”
The switch settings that you wrote down in
Step 2 will now become the button strokes
you enter into the Universal Home Remote in
Step 4. Be sure to enter the switch settings
that you wrote down in Step 2, in order from
left to right, into the Universal Home Remote,
when completing Step 4.
3. From inside your vehicle, rst rmly press
all three buttons at the same time for about
three seconds. Release the buttons to
put the Universal Home Remote into
programming mode.

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.
To signal a lane change, raise or lower the lever for
less than one second until the arrow starts to ash.
This will cause the turn signals to automatically
ash three times. It will ash six times if tow-haul
mode is active. Holding the turn signal lever for
more than one second will cause the turn signals to
ash until you release the lever. The lever will
return by itself when it is released.An arrow on the
instrument panel cluster
will ash in the
direction of the turn or
lane change.
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 will not
see your turn signal.
If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when
you signal a turn, check for burned-out bulbs and a
blown fuse. SeeFuses and Circuit Breakers on
page 564.
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 and the message TURN SIGNAL
ON will also appear in the Driver Information
Control (DIC). To turn the chime and message off,
move the turn signal lever to the off position.

To change the current mode, select one of the
following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to
the instrument panel outlets and to the oor
outlets. The ow can be divided between vent and
oor outlets depending upon where the knob is
placed between the settings. A little air is directed
towards the windshield and side window outlets.
Cooler air is directed to the upper outlets and
warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets, with some of the air directed
to the windshield, side window outlets, and second
row oor outlets. In this mode, the system will
automatically select outside air. Recirculation
cannot be selected when in Floor Mode.The right knob can also be used to select defog or
defrost mode. For more information, see
“Defogging and Defrosting” later in this section.
By positioning the right knob between two modes,
a combination of those two modes is selected.
The air conditioning compressor will be on unless
the outside temperature is close to freezing.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan
speed. Turn the knob all the way counterclockwise
to turn the front system off.
?(Recirculation):Press this button to turn the
recirculation mode on. When the button is pressed,
an indicator light will come on.
This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air and
prevent odors from entering your vehicle.
Recirculation may also help cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is less than the outside temperature.
