Power Door Locks
With power door locks, the switches on the front doors
can be used to lock and unlock the vehicle.
"(Unlock):Press to unlock the doors.
Q(Lock):Remove the key from the ignition and press
to lock the doors.
Delayed Locking
This feature allows the driver to delay the actual locking
of the doors. When the driver power door lock switch
is pressed with the key removed from the ignition, and
the driver door open, a chime will sound three times
to signal that the delayed locking system is active.
When all doors have been closed, the doors will lock
automatically after several seconds. If any door is
opened before this, the timer will reset itself once all
the doors have been closed again.
Pressing the driver or passenger power door lock switch
again or the RKE transmitter button will override this
feature.
Personal Choice Programming
The delayed locking feature can be turned on or off,
using the Driver Information Center (DIC) to program
this feature. See “DELAY DOOR LOCK” underDIC
Vehicle Customization on page 4‑65.
Programmable Automatic Door
Locks
Your vehicle is programmed so that, when the doors are
closed, the ignition is on, and the shift lever is moved
out of P (Park), all the doors will lock. The doors will
unlock every time you stop the vehicle and move the
shift lever into P (Park).
If someone needs to get out while your vehicle is not in
P (Park), have the person use the manual lock knob or
power door lock switch. When the door is closed again,
it will not lock automatically. Use the manual lock knob
or power door lock switch to lock the door.
If your vehicle has a Driver Information Center (DIC),
you can choose various lock and unlock settings.

information regarding Part 15 of the Federal
Communications Commission (FCC) Rules and
RSS-210/211 of Industry Canada.
PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle is equipped with PASS-Key®III+
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III+ is a passive
theft-deterrent system.
The system is automatically armed when the key is
removed from the ignition.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem with
arming or disarming the theft-deterrent system.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.
3-17

When trying to start the vehicle if the engine does not
start and the security light on the instrument panel
cluster comes on, there may be a problem with your
theft-deterrent system. Turn the ignition off and try
again.
If the engine still does not start, and the key appears to
be not damaged, try another ignition key. At this time,
you may also want to check the fuse, seeFuses and
Circuit Breakers
on page 6‑110. If the engine still does
not start with the other key, your vehicle needs service.
If your vehicle does start, the first key may be faulty.
See your dealer who can service the PASS-Key
®III+
to have a new key made. In an emergency, contact
Roadside Assistance. See Roadside Assistance
Program on page 8‑8.
It is possible for the PASS-Key
®III+ decoder to “learn”
the transponder value of a new or replacement key. Up
to 10 keys may be programmed for the vehicle. The
following procedure is for programming additional keys
only. If all the currently programmed keys are lost or do
not operate, you must see your dealer or a locksmith
who can service PASS-Key
®III+ to have keys made
and programmed to the system. See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.
To program the new key:
1. Verify that the new key has a
1stamped on it.
2. Insert the already programmed key in the ignition and start the engine. If the engine will not start, see
your dealer for service.
3. After the engine has started, turn the key to LOCK/OFF, and remove the key.
4. Insert the key to be programmed and turn it to the ON/RUN position within five seconds of the original
key being turned to the LOCK/OFF position.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys are to be programmed.
If you lose or damage your PASS-Key
®III+ key,
see your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.

Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:The vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
.Do not drive at any one constant speed, fast
or slow, for the first 500 miles (805 km).
Do not make full-throttle starts. Avoid
downshifting to brake or slow the vehicle.
.Avoid making hard stops for the first
200 miles (322 km) or so. During this time
the new brake linings are not yet broken in.
Hard stops with new linings can mean
premature wear and earlier replacement.
Follow this breaking-in guideline every time
you get new brake linings.
.Do not tow a trailer during break-in. See
Towing a Trailer
on page 5‑27for the trailer
towing capabilities of your vehicle and more
information.
Following break‐in, engine speed and load can be
gradually increased.
3-19

Ignition Positions
The ignition has four different positions:
In order to shift out of P (Park), ignition must be in
the ON/RUN and the regular brake pedal must be
applied.
Notice:Using a tool to force the key to turn in the
ignition could cause damage to the switch or break
the key. Use the correct key, make sure it is all the
way in, and turn it only with your hand. If the key
cannot be turned by hand, see your dealer.
A (LOCK/OFF): This position locks the ignition. It also
locks the transmission and steering column. This is the
only position in which the ignition key can be inserted or
removed. The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right to
left while turning the key to ACC/ACCESSORY. If this
doesn't work, then the vehicle needs service.
B (ACC/ACCESSORY):
This position lets the radio
and windshield wipers operate while the engine is off.
To use ACC/ACCESSORY, turn the key clockwise.
C (ON/RUN): This position can be used to operate
electrical accessories and to display some of the
warning and indicator lights. The switch stays in this
position when the engine is running.
If you leave the key in the ACC/ACCESSORY or
ON/RUN position with the engine off, the battery could
be drained. You may not be able to start the vehicle if
the battery is allowed to drain for an extended period
of time.
D (START): This position starts the engine. When the
engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound and the Driver Information
Center (DIC) will display DRIVER DOOR OPEN when
the driver door is opened if the ignition is in LOCK/OFF,
ACC/ACCESSORY and the key is in the ignition. See
DIC Warnings and Messages
on page 4‑55for more
information.

Retained Accessory Power (RAP)
The following accessories can be used for up to
10 minutes after the engine is turned off.
.Audio System
.Audio Steering Wheel (if equipped)
.Clock
.Power Windows
.Sunroof (if equipped)
Power to these accessories works up to 10 minutes or
until the driver door is opened.
The instrument panel cluster lights stay on for a few
seconds, then will go out. Once the driver door is
opened, the power shuts off to these accessories. The
vehicle has a feature designed to protect the battery
against drainage. For more information see Inadvertent
Power Battery Saver
on page 4‑16and Electric Power
Management on page 4‑16.
Starting the Engine
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart
the engine when the vehicle is already moving, use
N (Neutral) only.
Notice: Do not try to shift to P (Park) if the vehicle
is moving. If you do, you could damage the
transmission. Shift to P (Park) only when the
vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition to START. When the engine starts, let
go of the key. The idle speed will slow down
as the engine warms. Do not race the engine
immediately after starting it. Operate the engine
and transmission gently to allow the oil to warm up
and lubricate all moving parts.

Automatic Transmission Operation
The vehicle may have a shift lever located either on the
steering column or on the console between the seats.
P (Park):This position locks the front wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the 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 the
vehicle will not move, even when you are on fairly
level ground, always set the parking brake and
move the shift lever to P (Park). See Shifting Into
Park
on page 3‑27. If you are pulling a trailer,
see Towing a Trailer on page 5‑27.
Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to fully
apply the regular brakes before you can shift from
P (Park) while the ignition is in ON/RUN. If you cannot
shift out of P (Park), ease pressure on the shift lever
and push the shift lever all the way into P (Park) as you
maintain brake application. Then move the shift lever
into the gear you want. See Shifting Out of Park
on
page 3‑30.
