Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle may have a theft-deterrent alarm system.
A light located on top of your instrument panel, near the
center of the vehicle next to the windshield, will ash
slowly to let you know that the system has been armed.While armed, the doors will not unlock with the power
door lock switch.
Once armed, the alarm will go off if someone tries to
enter the vehicle without using the remote keyless entry
transmitter or a key, or turns the ignition to ON. The
horn will sound and the parking lamps will ash for up to
two minutes.
When the alarm is armed, the liftgate may be opened
with the remote keyless entry transmitter.
Arming with the Power Lock Switch
Your alarm system will arm when you use either power
door lock switch to lock the doors while any door or
the liftgate is open and the key is removed from
the ignition. If you would like to turn on power door lock
switch arming, seeVehicle Personalization on
page 2-55.
When the security light ashes quickly the system is
ready to arm with the power door lock switches.
Then the security light will stop ashing and stay on
when you press the rear of the power door lock switch,
to let you know the system is arming. After all doors
and the liftgate are closed and locked, the security light
will begin ashing at a very slow rate to let you know
the system is armed.
2-25

Arming with the Remote Keyless Entry
Transmitter
Your alarm system will arm when you use your remote
keyless entry transmitter to lock the doors, if the key
is not in the ignition. The security light will turn on to let
you know the system is arming. After all doors and
the liftgate are closed and locked, the security light will
begin ashing at a very slow rate to let you know
the system is armed.
Arming with Your Key
Your alarm system will arm when you use your key to
lock the driver’s door. The security light will turn on to let
you know the system is arming. After all doors and
the liftgate are closed and locked, the security light will
begin ashing at a very slow rate to let you know
the system is armed. If you would like your key not to
arm the system, seeVehicle Personalization on
page 2-55.
Arming Conrmation
If remote unlock conrmation is on, your parking lamps
will ash briey to let you know when your alarm
system has disarmed. If you would not like the parking
lamps to ash, seeVehicle Personalization on
page 2-55.
Disarming with the Remote Keyless
Entry Transmitter
Your alarm system will disarm when you use your
remote keyless entry transmitter to unlock the doors.
The security light will stop ashing to let you know the
system is no longer armed.
Disarming with Your Key
Your alarm system will disarm when you use your key
to unlock the driver’s door. The security light will

PASS-Key®III
Your PASS-Key®III system operates on a radio
frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
PASS-Key
®III uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key®III Operation
Your vehicle is equipped
with the PASS-Key®III
(Personalized Automotive
Security System)
theft-deterrent system.
PASS-Key
®III is a passive
theft deterrent system.
This means you do
not have to do anything
different to arm or disarm
the system. It works
when you insert or remove
the key from the ignition.
When the PASS-Key
®III system senses that someone
is using the wrong key, it shuts down the vehicle’s
starter and fuel systems. The starter will not work and
fuel will stop being delivered to the engine. 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 message
comes on, the key may have a damaged transponder.
Turn the ignition off and try again.
2-27

5. The security message will turn off once the key has
been programmed. It may not be apparent that the
security message went on due to how quickly
the key is programmed.
6. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you are ever driving and the security message comes
on and stays on, you will be able to restart your
engine if you turn it off. Your PASS-Key
®III system,
however, is not working properly and must be serviced
by your dealer. Your vehicle is not protected by the
PASS-Key
®III system at this time.
If you lose or damage a PASS-Key
®III key, see your
dealer or a locksmith who can service PASS-Key®III to
have a new key made.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your 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 speed, fast or slow, for
the rst 500 miles (805 km). Do not make
full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your 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. SeeTowing a
Trailer on page 4-36for more information.
