could be badly injured or even killed. They could
operate the power windows or other controls or
even make the vehicle move. The windows will
function and they could be seriously injured or
killed if caught in the path of a closing window.
Do not leave keys in a vehicle with children.

window lockout button to prevent unintentional
operation of the windows.
The power window
switches are located on

not reverse automatically. You or others could
be injured and the window could be damaged.

active, close all doors.
2. Press and hold the power window switch until the window is fully open.

The window is now reprogrammed. Repeat the process
for the other windows.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however, they
do not make it impossible to steal.
Content Theft-Deterrent
Your vehicle may have a content theft-deterrent alarm
system.
This is the security light.To arm the theft-deterrent system:
1. Open the door.
2. Lock the door with the Remote Keyless Entry (RKE) transmitter or the power door lock switch.
The security light will come on to inform the driver
the system is arming. If a door is open when the
doors are locked, the security light will flash.
If the delayed locking feature is turned on, the
theft‐deterrent system will not start the arming
process until the last door is closed and the delay
timer has expired. See Delayed Locking
on
page 3‑11.
3. Close all doors. The security light should go off after about 30 seconds. The alarm is not armed
until the security light goes off.
If a locked driver door is opened without using the RKE
transmitter, a ten second pre-alarm will occur. The horn
will chirp and the lights will flash. If the key is not placed
in the ignition and turned to START or the door is not
unlocked by pressing the unlock button on the RKE
transmitter during the ten second pre-alarm, the alarm
will go off. Your vehicle's headlamps will flash and the
horn will sound for about 30 seconds, then will turn off
to save the battery power.
3-23

The theft-deterrent system will not activate if the doors
are locked with the vehicle's key or the manual door
lock. It activates only if you use the power door lock
switch with the door open or the RKE transmitter.
You should also remember that you can start your
vehicle with the correct ignition key if the alarm has
been set off.
To avoid setting off the alarm by accident:
.If you do not want to activate the theft-deterrent
system, the vehicle should be locked with the door
key after the doors are closed.
.Always unlock the doors with the RKE transmitter.
Unlocking a door any other way will set off the
alarm if it is armed.
If you set off the alarm by accident, press unlock on the
RKE transmitter or place the key in the ignition and turn
it to START to turn off the alarm. The alarm will not stop
if you try to unlock a door any other way.
Testing the Alarm
To test the alarm: 1. From inside the vehicle, lower the driver's window and open the driver's door.
2. Activate the system by locking the doors with the power door lock switch while the door is open,
or with the RKE transmitter.
3. Get out of the vehicle, close the door and wait for the security light to go out.
4. Then reach in through the window, unlock the door with the manual door lock and open the door.
This should set off the alarm.
While the alarm is set, the power door unlock switch will
not work.
If the alarm does not sound when it should but the
headlamps flash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
see Fuses and Circuit Breakers on page 6‑118.
If the alarm does not sound or the headlamps do not
flash, the vehicle should be serviced by your dealer.

Communications Commission (FCC) Rules and
RSS-210/211 of Industry Canada.
PASS-Key®III+ Electronic
Immobilizer Operation
Your vehicle has 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.
The system is automatically disarmed when the key is
turned to ON/RUN, ACC/ACCESSORY or START from
the LOCK/OFF position. 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.
If the engine does not start and the security light on
the instrument panel cluster comes on when trying to
start the vehicle, 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 undamaged, try another ignition key. At this time,
you may also want to check the fuse, see Fuses and
Circuit Breakers
on page 6‑118. 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.

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 additional key:
1. Verify that the new key has a
1stamped on it.
2. Insert the original, 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 new key to be programmed and turn it to the ON/RUN position within five seconds of turning
the ignition to the LOCK/OFF position in Step 3.
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:
.Keep your speed at 55 mph (88 km/h) or less
for the first 500 miles (805 km).
.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 5‑49for the trailer
towing capabilities of the vehicle and more
information.
Following break‐in, engine speed and load can be
gradually increased.

Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
or ACC/ACCESSORY and the regular brake pedal must
be applied. A (LOCK/OFF):
This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. The key can be removed in LOCK/OFF.
On vehicles with an automatic transmission, the shift
lever must be in P (Park) to turn the ignition switch to
LOCK/OFF.
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.
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.
