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.
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 5-101. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See your
dealer/retailer who can service the PASS-Key
®III+ to
have a new key made. In an emergency, contact
Roadside Assistance. SeeRoadside Assistance
Program on page 7-7.
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/retailer or a
locksmith who can service PASS-Key
®III+ to have keys
made and programmed to the system.
See your dealer/retailer 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.

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/retailer.
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. SeeDIC Warnings and Messages on page 3-56
for 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 seeInadvertent
Power Battery Saver on page 3-19andElectric
Power Management on page 3-19.
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.
2-22

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.
The 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 will continue
cranking for a few seconds or until the vehicle starts.
If the engine does not start and the key is held in
START, cranking will be stopped 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 ACC/
ACCESSORY or LOCK/OFF 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 let the cranking motor 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, repeat these steps. 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:The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the engine
operates. Before adding electrical equipment, check
with your dealer/retailer. If you do not, the engine
might not perform properly. Any resulting damage
would not be covered by the vehicle warranty.

Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm-up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged
in at least four hours before starting.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
On vehicles with the 3.9L V6 engine, the coolant
heater cord is located on the driver side of the
vehicle, near the strut tower. On vehicles with the
4.6L V8 engine, the cord is located on the driver
side of the vehicle on the right side of the engine air
cleaner. It is between the engine cover and the
engine air cleaner.
{CAUTION:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a re.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
3. Plug the cord into a normal, grounded 110-volt
AC outlet.
4. Before starting the engine, be sure to unplug and
store the cord as it was before to keep it away
from moving engine parts, and prevent damage.
The length of time the heater should remain plugged in
depends on several factors. Ask a dealer/retailer in
the area where you will be parking the vehicle for the
best advice on this.
2-24

R (Reverse):Use this gear to back up.
Notice:Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
To rock the vehicle back and forth to get out of snow, ice,
or sand without damaging the transmission, seeIf Your
Vehicle is Stuck in Sand, Mud, Ice, or Snow on
page 4-17.
N (Neutral):In this position, the engine does not
connect with the wheels. To restart the engine when the
vehicle is already moving, use N (Neutral) only. Also,
use N (Neutral) when the vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is rmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.Notice:Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage
the transmission. The repairs would not be covered
by the vehicle warranty. Be sure the engine is
not running at high speed when shifting the vehicle.
D (Drive):This position is for normal driving.
It provides the best fuel economy. If you need more
power for passing, and you are:
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.
The transmission will shift down to the next gear and
have more power.
Downshifting the transmission in slippery road conditions
could result in skidding, see “Skidding” underLoss of
Control on page 4-10
3 (Third):This position is also used for normal driving.
It reduces vehicle speed more than D (Drive) without
using the brakes. You might choose 3 (Third) instead of
D (Drive) when driving on hilly, winding roads, when
towing a trailer, so there is less shifting between gears
and when going down a steep hill.
2-26

Leaving the Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly if
the shift lever is not fully in P (Park) with the parking
brake rmly set. And, if you leave the vehicle with
the engine running, it could overheat and even
catch re. You or others could be injured. Do not
leave the vehicle with the engine running.
If you have to leave the vehicle with the engine running,
be sure your vehicle is in P (Park) and the parking
brake is rmly set before you leave it. SeeParking Brake
on page 2-27for more information.
Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then it
is difficult to shift out of P (Park). To prevent torque lock,
set the parking brake and then shift into P (Park). To nd
out how, see “Shifting Into Park” in this section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
2-30

Shifting Out of Park
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal unless the shift lever is
in P (Park)
Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN and the regular
brake pedal is applied.
The shift lock is always functional except in the case of a
an uncharged or low voltage (less than 9 volt) battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 5-46.
Console Shift
If the console shifter cannot be moved out of P (Park)
1. Apply and maintain the regular brakes.
2. Turn the ignition to ON/RUN position. SeeIgnition
Positions on page 2-21for more information.
3. Let up on the shift lever and make sure the shift
lever is pushed all the way into P (Park).
4. Then, move the shift into the desired gear.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.
Column Shift
If the shifter cannot be moved out of P (Park)
1. Apply and maintain the regular brakes.
