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 previously
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 previously, 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.

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
previously 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.

Ignition Positions
Use the key to turn the ignition switch to
four different positions.
A (LOCK):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will
only be able to remove the key when the ignition
is turned to LOCK.Notice:If your key seems stuck in LOCK and
you cannot turn it, be sure you are using
the correct key; if so, is it all the way in? Turn
the key only with your hand. Using a tool to
force it could break the key or the ignition
switch. If none of these works, then your
vehicle needs service.
B (ACCESSORY):This position lets you use
things like the radio and the windshield wipers
when the engine is off.
Lengthy operation of features such as the radio in
the accessory ignition position may drain the
battery and prevent your vehicle from starting.
Do not operate your vehicle in the accessory
ignition position for a long period of time.
C (RUN):This is the position for driving.
The battery could be drained if you leave the key
in the ACCESSORY or RUN position with the
engine off. You may not be able to start your
vehicle if the battery is allowed to drain for
an extended period of time.
D (START):This position starts the engine.
113

Key In the Ignition
Never leave your vehicle with the keys inside, as it
is an easy target for joy riders or thieves. If you
leave the key in the ignition and park your vehicle,
a chime will sound, when you open the driver’s
door. Always remember to remove your key from
the ignition and take it with you. This will lock
your ignition and transmission. Also, always
remember to lock the doors.
The battery could be drained if you leave the key
in the ignition while your vehicle is parked.
You may not be able to start your vehicle after it
has been parked for an extended period of time.
Retained Accessory Power (RAP)
Your vehicle has a Retained Accessory
Power (RAP) feature which lets certain features of
your vehicle to continue to work up to 20 minutes
after the ignition key is turned to LOCK.
The radio, power windows, the overhead console
and the sunroof, if the vehicle has one, work
when the ignition key is in RUN or ACCESSORY.
Once the key is turned from RUN to LOCK,
these features continue to work for up to
20 minutes, or until a door is opened.
Starting the Engine
Place the transmission in the proper gear.
Move your shift lever to PARK (P) or
NEUTRAL (N). Your engine will not start in
any other position -- this is a safety feature.
To restart when you are already moving, use
NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P)
if your vehicle is moving. If you do, you could
damage the transmission. Shift to PARK (P)
only when your vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn
the ignition key to START. When the engine
starts, let go of the key. The idle speed will
goes as your engine gets warm. Do not race
the engine immediately after starting it.
Operate the engine and transmission gently
to let the oil to warm up and lubricate all
moving parts.
114

Your vehicle has a Computer-Controlled
Cranking System. This feature assists in
starting the engine and protects components.
If the ignition key is turned to the START
position, and then released when the engine
begins cranking, the engine continues cranking
for a few seconds or until the vehicle starts.
If the engine does not start and the key is held
in START for many seconds, cranking stops
after 15 seconds to prevent cranking motor
damage. To prevent gear damage, this system
also prevents cranking if the engine is
already running. Engine cranking can be
stopped by turning the ignition switch to the
ACCESSORY or LOCK position.
Notice:Cranking the engine for long periods
of time, by returning the key to the START
position immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down.2. If the engine does not start after 5-10 seconds,
especially in very cold weather (below 0°F
or−18°C), it could be ooded with too much
gasoline. Try pushing the accelerator
pedal all the way to the oor and holding it
there as you hold the key in START for up to
a maximum of 15 seconds. Wait at least
15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator.
If the vehicle starts briey but then stops
again, do the same thing. This clears the extra
gasoline from the engine. Do not race the
engine immediately after starting it. Operate
the engine and transmission gently until the oil
warms up and lubricates all moving parts.
Notice:Your engine is designed to work with
the electronics in your vehicle. If you add
electrical parts or accessories, you could
change the way the engine operates. Before
adding electrical equipment, check with your
dealer. If you do not, your engine might not
perform properly. Any resulting damage would
not be covered by your vehicle’s warranty.

Automatic Transmission Operation
There are several different positions for your gear
shift lever.
PARK (P):This position locks the rear wheels.
It is the best position to use when you start the
engine because your vehicle cannot 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.
Do not 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 will not
move, even when you are on fairly level
ground, always set your parking brake
and move the shift lever to PARK (P).
SeeShifting Into Park (P) on page 127.
If you are pulling a trailer, seeTowing a
Trailer on page 362.

{CAUTION:
If you have four-wheel drive, your vehicle
will be free to roll — even if your shift
lever is in PARK (P) — if your transfer
case is in NEUTRAL. So, be sure the
transfer case is in a drive gear — not in
NEUTRAL. SeeFour-Wheel Drive on
page 122. SeeShifting Into Park (P) on
page 127.

before starting the engine. Your vehicle has an
automatic transmission shift lock control system.You have to fully apply the regular brakes rst and
then press the shift lever button 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 and push the shift
lever all the way into PARK (P) as you maintain
brake application. Then press the shift lever button
and move the shift lever into another gear. See
Shifting Out of Park (P) on page 129.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your
vehicle is moving forward could damage the
transmission. The repairs would not be covered
by your warranty. Shift to REVERSE (R) only
after your vehicle is stopped.
