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.
3. You are now ready to program the automatic door
locks. Select one of the three 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
modi®ed.
See your dealer for more information.

Automatic Transmission Operation
There are several different positions for your gear
shift lever.
PARK (P):This position locks the rear wheels. It's the
best position to use when you start the engine
because your vehicle can't move easily.
{CAUTION:
It is dangerous to get out of your vehicle if the
shift lever is not fully in PARK (P) with the
parking brake ®rmly set. Your vehicle can roll.
Don't leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move
suddenly. You or others could be injured. To
be sure your vehicle won't move, even when
you're on fairly level ground, always set your
parking brake and move the shift lever to
PARK (P). See ªShifting Into Park (P)º in the
Index. If you're pulling a trailer, see ªTowing a
Trailerº in the Index.
{CAUTION:
If you have four-wheel drive, your vehicle will
be free to roll Ð even if your shift lever is in
PARK (P) Ð if your transfer case is in
NEUTRAL. So, be sure the transfer case is in a
drive gear Ð not in NEUTRAL. See
ªFour-Wheel Drive (Automatic Transfer Case)º
in the Index. See ªShifting Into Park (P)º in
the Index.
Ensure the shift lever is fully in PARK (P) before starting
the engine. Your vehicle has an automatic transmission
shift lock control system. You have to fully apply the
regular brakes before you can shift from PARK (P) when
the ignition key is in RUN. If you cannot shift out of
PARK (P), ease pressure on the shift lever, press the
button on the shift lever and push the shift lever all
the way into PARK (P) as you maintain brake
application. Move the shift lever into the gear you wish.
See
Shifting Out of Park (P) on page 2-31.
2-23

REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage your transmission.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
see If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-44.
NEUTRAL (N):In this position, the engine doesn't
connect with the wheels. To restart when you're already
moving, use NEUTRAL (N) only.
{CAUTION:
Shifting into a drive gear while your engine is
ªracingº (running at high speed) is dangerous.
Unless your foot is ®rmly on the brake pedal,
your vehicle could move very rapidly. You
could lose control and hit people or objects.
Don't shift into a drive gear while your engine
is racing.
Notice:Damage to your transmission caused by
shifting out of PARK (P) or NEUTRAL (N) with
the engine racing isn't covered by your warranty.On cold days, about 32É F (0ÉC) or colder, your
transmission is designed to shift differently until the
engine reaches normal operating temperature. This is
intended to improve heater performance.
DRIVE (D):This position is for normal driving. If you
need more power for passing, and you're:
·Going less than about 35 mph (55 km/h), push the
accelerator pedal about halfway down.
·Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
DRIVE (D) can be used when towing a trailer, carrying
a heavy load, driving on steep hills or for off-road driving.
You may want to shift the transmission to THIRD (3)
or, if necessary, a lower gear selection if the
transmission shifts too often.
THIRD (3):This position is also used for normal driving.
However, it offers more power and lower fuel economy
than DRIVE (D).
SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control your speed as
you go down steep mountain roads, but then you
would also want to use the brakes off and on.
You can also use SECOND (2) for starting the vehicle
from a stop on slippery road surfaces.
2-24

FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
selector lever is put in FIRST (1) while the vehicle
is moving forward, the transmission won't shift into ®rst
gear until the vehicle is going slowly enough.
Notice:If your wheels won't turn, don't try to drive.
This might happen if you were stuck in very deep
sand or mud or were up against a solid object. You
could damage your transmission. Also, if you
stop when going uphill, don't hold your vehicle there
with only the accelerator pedal. This could overheat
and damage the transmission. Use your brakes
or shift into PARK (P) to hold your vehicle in
position on a hill.
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 in the 4-WHEEL HIGH (4HI) or
4-WHEEL LOW (4LO) positions for a long time on
dry or wet pavement could shorten the life of
your vehicle's drivetrain.
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.

Shifting into 4LO
To shift to 4LO, the vehicle's engine must be running
and the vehicle must be stopped or moving less
than 2 mph (3.2 km/h) with the transmission in
NEUTRAL (N). The preferred method for shifting into
4LO is to have your vehicle moving 1 or 2 mph (1.6 to
3.2 km/h). Turn the knob to 4LO. You must wait for
the 4LO indicator light to stop ¯ashing and remain
illuminated before shifting your transmission into gear.
If you turn the knob to 4LO when your vehicle is in gear
and/or moving, the 4LO indicator light will ¯ash for
30 seconds and not complete the shift unless your
vehicle is moving less than 2 mph (3.2 km/h) and the
transmission is in NEUTRAL (N). After 30 seconds, the
transfer case will return to the setting last chosen.
Shifting Out of 4LO
To shift from 4LO to 4HI, A4WD or 2HI your vehicle
must be stopped or moving less than 2 mph (3.2 km/h)
with the transmission in NEUTRAL (N) and the
engine running. The preferred method for shifting out of
4LO is to have your vehicle moving 1 or 2 mph (1.6
to 3.2 km/h). Turn the knob to 4HI, A4WD or 2HI. You
must wait for the 4HI, A4WD or 2HI indicator light to stop
¯ashing and remain illuminated before shifting your
transmission into gear.If the knob is turned to 4HI, A4WD or 2HI when your
vehicle is in gear and/or moving, the 4HI, A4WD or 2HI
indicator light will ¯ash for 30 seconds. It will not
complete the shift unless your vehicle is moving less
than 2 mph (3.2 km/h) with the transmission in
NEUTRAL (N).
Shifting into NEUTRAL
Before shifting the transfer case to NEUTRAL, ®rst
make sure the vehicle is parked so that it will not roll.
1. Set the parking brake.
2. Start the vehicle.
3. Put the transmission in NEUTRAL (N).
4. Shift the transfer case to 2HI.
5. Turn the transfer case knob all of the way past 4LO
and hold it there for a minimum of 10 seconds. The
neutral indicator light will come on.
6. Shift the transmission to REVERSE (R) for one
second, then shift the transmission to DRIVE (D)
for one second.
7. Place the transmission shift lever in PARK (P).
8. Release the parking brake prior to towing.
9. Turn the ignition to LOCK.

Notice:Driving with the parking brake on can
cause your parking brake to overheat. You may have
to replace them, and you could also damage other
parts of your vehicle.
If you are towing a trailer and you must park on a hill,
see
Towing a Trailer on page 4-50. That section
shows what to do ®rst to keep the trailer from moving.
Shifting Into Park (P)
{CAUTION:
It can be dangerous to get out of your vehicle
if the shift lever is not fully in PARK (P) with
the parking brake ®rmly set. Your vehicle can
roll. If you have left the engine running, the
vehicle can move suddenly. You or others
could be injured. To be sure your vehicle won't
move, even when you're on fairly level ground,
CAUTION: (Continued)
CAUTION: (Continued)
use the steps that follow. With four-wheel
drive, your vehicle will be free to roll Ð even if
your shift lever is in PARK (P) Ð if your
transfer case is in NEUTRAL. So, be sure the
transfer case is in a drive gear Ð not in
NEUTRAL. See ªFour-Wheel Driveº in the
Index. Always put the shift lever fully in
PARK (P) with the parking brake ®rmly set. If
you're pulling a trailer, see ªTowing a Trailerº
in the Index.
To shift into PARK (P), do the following:
1. Hold the brake pedal down with your right foot and
set the parking brake.

Running
{CAUTION:
It can be dangerous to leave your vehicle
with the engine running. Your vehicle could
move suddenly if the shift lever is not fully in
PARK (P) with the parking brake ®rmly set.
If you have four-wheel drive, your vehicle
will be free to roll ± even if your lever is in
PARK (P) ± if your transfer case is in
NEUTRAL. So be sure the transfer case is in a
drive gear ± not NEUTRAL. See ªFour-Wheel
Drive (Automatic Transfer Case)º in the Index.
And, if you leave the vehicle with the engine
running, it could overheat and even catch ®re.
You or others could be injured. Don't leave
your vehicle with the engine running unless
you have to.

Outside Convex Mirror
A convex mirror's surface is curved so you can see
more from the driver's seat.
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right or left lane,
you could hit a vehicle. Check your inside
mirror or glance over your shoulder before
changing lanes.
Outside Heated Mirrors
Your vehicle may have this feature.
When you operate the rear window defogger, a defogger
also warms the heated driver's and passenger's
outside rearview mirrors to help clear them of ice, snow
and condensation.
Outside Automatic Dimming Mirror
with Curb View Assist
If your vehicle has this feature, the driver's and/or
passenger's outside mirror will adjust to a preset tilt
position while the vehicle is in REVERSE (R) gear. Curb
view assist may be useful when you are parallel
parking. The mirror(s) will return to normal position
when the vehicle is shifted out of REVERSE (R) gear.
Automatic mirror movement in either direction will follow
a short delay.
To change the tilt position, adjust the mirror while the
vehicle is in REVERSE (R) gear with the engine running,
the parking brake engaged and the brake pedal
pressed. The new position will be saved into memory
once the vehicle is shifted out of REVERSE (R).
You may be able to enable/disable this feature through
the Driver Information Center (DIC). See Mirror Curb
View Assist under
DIC Operation and Displays on
page 3-51.

Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
·Use the accelerator pedal to get to the higher
speed. Press the button at the end of the lever, then
release the button and the accelerator pedal.
You'll now cruise at the higher speed.
·Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch brie¯y to resume/accelerate. Each
time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
Press in the set button at the end of the lever until you
reach the lower speed you want, then release it.
Each time you do this, you'll go about 1 mph (1.6 km/h)
slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers ®nd this to be too much trouble and don't use
cruise control on steep hills.
Ending Cruise Control
There are three ways to turn off the cruise control:
·Step lightly on the brake pedal.
·Move the cruise switch to off, or
·Shift the transmission to NEUTRAL (N).
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
