Shifting Out of NEUTRAL
To shift out of NEUTRAL do the following:
1. Set the parking brake and apply the regular
brake pedal.
2. Shift the transmission to NEUTRAL (N) and
turn the ignition to RUN with the engine off.
3. Turn the transfer case dial to
Two-Wheel-Drive High.
After the transfer case has shifted out of
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 requested mode indicator light has
stopped ashing could damage the transfer
case. To help avoid damaging your vehicle,
always wait for the mode indicator lights
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.
Automatic Transfer Case
The transfer case knob
is located next to the
steering column.

4n(Four-Wheel-Drive Low):This setting also
engages the front axle and delivers extra
torque. You may never need this setting. It sends
maximum power to all four wheels. You might
choose Four-Wheel-Drive Low if you are driving
off-road in deep sand, deep mud, deep snow, and
while climbing or descending steep hills.
StabiliTrak
®will not engage in this mode. See
StabiliTrak®System on page 384for more
information.
{CAUTION:
Shifting the transfer case to NEUTRAL
can cause your vehicle to roll even if the
transmission is in PARK (P). You or
someone else could be seriously injured.
Be sure to set the parking brake before
placing the transfer case in NEUTRAL.
SeeParking Brake on page 164.N (NEUTRAL):Shift the vehicle’s transfer case to
NEUTRAL only when towing your vehicle. See
Recreational Vehicle Towing on page 442or
Towing Your Vehicle on page 441for more
information.
If the SERVICE 4–Wheel Drive message stays on,
you should take your vehicle to your dealer for
service. See “Service 4–Wheel Drive message”
underDIC Warnings and Messages on page 281.
Shifting Into Four-Wheel-Drive High or
AUTO (Automatic Four-Wheel Drive)
Turn the knob to the Four-Wheel-Drive High or
AUTO position. This can be done at any speed,
except when shifting from Four-Wheel-Drive
Low, and the indicator light will ash while shifting.
It will remain on when the shift is completed.

Shifting Into Two-Wheel-Drive High
Turn the knob to the Two-Wheel-Drive High
position. This can be done at any speed, except
when shifting from Four-Wheel-Drive Low.
Shifting Into Four-Wheel-Drive Low
When Four-Wheel-Drive Low is engaged, vehicle
speed should be kept below 45 mph. Extended
high-speed operation in Four-Wheel-Drive
Low may damage or shorten the life of the
drivetrain.
To shift to the Four-Wheel-Drive Low position, the
ignition must be in RUN and the vehicle must
be stopped or moving less than 3 mph (5 km/h)
with the transmission in NEUTRAL (N). The
preferred method for shifting into Four-Wheel-Drive

stopped ashing could damage the transfer
case. To help avoid damaging your vehicle,
always wait for the mode indicator lights
to stop ashing before shifting the
transmission into gear.
It is typical for your vehicle to exhibit
signicant engagement noise and bump when
shifting between Four-Wheel-Drive Low and
Four-Wheel-Drive High ranges or from NEUTRAL
with the engine running.
If the knob is turned to the Four-Wheel-Drive Low
position when your vehicle is in gear and/or
moving, the Four-Wheel-Drive Low indicator light
will ash for 30 seconds and not complete the
shift unless your vehicle is moving less than 3 mph
(5 km/h) and the transmission is in NEUTRAL (N).
After 30 seconds the transfer case will shift to
Four-Wheel-Drive High mode.
161

Shifting Out of Four-Wheel-Drive Low
To shift from Four-Wheel-Drive Low to
Four-Wheel-Drive High, AUTO or
Two-Wheel-Drive High, your vehicle must be
stopped or moving less than 3 mph (5 km/h) with

163

Torque Lock
If you are parking on a hill and you do not shift
your transmission into PARK (P) properly,
the weight of the vehicle may put too much force
on the parking pawl in the transmission. You
may nd it difficult to pull the shift lever out
of PARK (P). This is called torque lock. To prevent
torque lock, set the parking brake and then shift
into PARK (P) properly before you leave the
driver’s seat. To nd out how, seeShifting Into
Park (P) on page 165.
When you are ready to drive, move the shift lever
out of PARK (P) before you release the parking
brake.
If torque lock does occur, you may need to have
another vehicle push yours a little uphill to
take some of the pressure from the parking pawl
in the transmission, then you will be able to
pull the shift lever out of PARK (P).
Shifting Out of Park (P)
Your vehicle has an automatic transmission shift
lock control system which locks the shift lever
in PARK (P) when the ignition is in the LOCK. You
have to fully apply your regular brakes before
you can shift from PARK (P) when the ignition is
in RUN. SeeAutomatic Transmission Operation on
page 140.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the
way up into PARK (P) as you maintain brake
application. Move the shift lever into another gear.

Read the instructions completely before attempting
to program the Universal Home Remote.
Because of the steps involved, it may be helpful to
have another person available to assist you in
the programming steps
Keep the original hand-held transmitter for use in
other vehicles as well as for future Universal Home
Remote programming. It is also recommended that
upon the sale of the vehicle, the programmed
Universal Home Remote buttons should be erased
for security purposes. See “Erasing Universal
Home Remote Buttons” later in 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
gate operator you are programming.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.Programming the Universal Home
Remote System
Follow these steps to program up to three
devices:
1. Press and hold down the two outside
Universal Home Remote buttons, releasing
only when the Universal Home Remote
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 hand-held transmitter to the remaining
two Universal Home Remote buttons.
2. Hold the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from
the Universal Home Remote buttons
while keeping the indicator light in view.
3. At the same time, press and hold both the
desired Universal Home Remote button 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.
188

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.
