Theft
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. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your steering wheel will be locked, and so will your
ignition and transaxle. And remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.
Parking Lots
If you park in a lot where someone will be watching
your vehicle, it's best to lock it up and take your keys.
But what if you have to leave your ignition key?

If possible, park in a busy, well lit area.

Put your valuables in a storage area, like your
trunk or glove box. Be sure to close and lock the
storage area.

Close all windows.

Move the trunk release lockout switch to ON.

Lock the glove box.

Lock all the doors except the driver's.

Then take the door key and remote keyless entry
transmitter with you.

Lock all doors except the driver's.

Give the valet key to the valet. Then take the master
key with you.

2-14
Theft-Deterrent System
If the ignition is off and
any door is open, the
SECURITY light will
flash, reminding you to
arm the system.
To arm the system, do the following:
1. Open the door.
2. Lock the door using the power door lock switch with
the door open or the Remote Keyless Entry (RKE)
system. The SECURITY light should come on and
stay on.
3. Close all the doors. The SECURITY light should
go off within approximately 30 seconds.
When the theft system activates, the horn will sound and
the lamps will flash for about 30 seconds when the door
or trunk is opened without the key or RKE system.Remember, the theft
-deterrent system won't arm if you
lock the doors with a key or use the manual door lock.
It activates only if you use a power door lock with the
door open or the RKE system.
To avoid activating the alarm by accident:

The vehicle should be locked with the door key or
the manual door lock after the doors are closed if
you don't want to arm the theft
-deterrent system.

Always unlock a door with a key or use the RKE
system. (Pressing the unlock button on the RKE
transmitter disables the theft
-deterrent system.)
Unlocking a door any other way will activate the
alarm when a door or the trunk is opened.
If you activate the alarm by accident, unlock the driver's
door with your key. You can also turn off the alarm by
using the unlock button on the RKE system, or by
starting the car with a valid key.
Changes or modifications made to this system by
other than an authorized service facility could void
authorization to use the theft system.

2-15 Testing the Alarm
1. From inside the vehicle, roll down the window,
then get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open,
lock the vehicle using the power door lock or the
RKE system and close the door. Wait 30 seconds
until the SECURITY lamp goes off.
3. Reach in and unlock the door using the manual lock
and open the door. The horn will sound and the
hazard lights will flash.
You can turn off the alarm by unlocking the driver's
door with your key, using the unlock button on the
RKE transmitter or by starting the car with a valid key.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown.
To replace the fuse, see ªFuses and Circuit Breakersº
in the Index. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
theft
-deterrent system when leaving your vehicle.
Valet Lock
This switch is located inside the glove box on the left
side. Pressing this switch to ON will disable the use of
the trunk, fuel door and garage door opener.
Pressing this switch to
OFF will enable these
features for use.
Locking the glove box with your key will also help to
secure your vehicle. Note that the RKE transmitter can't
open the trunk or fuel door if the valet lock switch is in
the ON position.

2-16
PASS-Key
III
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 don't have to do
anything different to arm or
disarm the system. It works
when you insert or remove
the key from the ignition.
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,
and (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, and (2)
this device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modifications 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.
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.
When trying to start the vehicle and the engine does not
start and the SECURITY light comes on, the key may
have a damaged transponder. Turn the ignition off and
try again.

2-17
If the engine 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 ªFuses and Circuit
Breakersº in the Index). 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 or a locksmith who can service the PASS
-Key III
to have a new key made.
It is possible for the PASS
-Key III decoder to learn
the transponder value of a new or replacement key.
Up to ten additional keys may be programmed for the
vehicle. This procedure is for learning additional keys
only. If all the currently programmed keys are lost or
do not operate, you must see your dealer or 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 blank key that is cut
exactly as a current black colored driver's key that
operates the system. Do not use the gray colored
valet key for this procedure.To program the new key:
1. Insert the current driver's key (black in color) in the
ignition and start the engine. If the engine will not
start, see your dealer for service.
2. After the engine has started, turn the key to OFF and
remove the key.
3. Insert the key to be programmed and turn it to RUN
within ten seconds of removing the previous key.
4. The SECURITY light will turn off once the key has
been programmed. It may not be apparent that the
SECURITY light went on due to how quickly the
key is programmed.
5. Repeat the Steps 1 through 4 if additional keys are
to be programmed.
If you are ever driving and the SECURITY light
comes on and stays on, you will be able to start 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.

2-18
New Vehicle ªBreak-Inº
NOTICE:
Your vehicle doesn't need an elaborate ªbreak-in.º
But it will perform better in the long run if you
follow these guidelines:

Don't drive at any one speed -- fast or
slow
-- for the first 500 miles (805 km).
Don't make full
-throttle starts.

Avoid making hard stops for the first 200 miles
(322 km) or so. During this time your new
brake linings aren't 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.

Don't tow a trailer during break
-in.
See ªTowing a Trailerº in the Index for
more information.
Ignition Positions
With the key in the ignition switch, you can turn the key
to four different positions:
OFF: This position lets
you turn off the engine
and remove the key.
This position also locks
the steering wheel
and transaxle.
NOTICE:
If your key seems stuck in OFF and you can't
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 this
works, then your vehicle needs service.

2-19
ACC: This position lets you use things like the radio,
windshield wipers, power windows and sunroof (option)
when the engine is off. Use ACC if you must have your
vehicle in motion while the engine is off (for example,
if your vehicle is being pushed).
ON: This is the position for driving.
START: This position starts the engine.
Retained Accessory Power (RAP)
The following accessories on your vehicle may be used
for up to 10 minutes after the ignition key is turned from
ON to OFF:

Cellular Phone (If Equipped)

Radio

Power Windows

Audio Steering Wheel Controls

Sunroof (Option)Power to these accessories stops after 10 minutes or
if any door is opened. If you want power for another
10 minutes, close all the doors and turn the ignition key
to ON and then back to OFF. If the cellular phone is
being used while Retained Accessory Power is in effect,
the timer is suspended (to avoid interruption of the call).
The timer resets to 10 minutes at the end of the call.
Starting Your Engine
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine won't start in any other position
-- that's
a safety feature. To restart when you're already moving,
use NEUTRAL (N) only.
NOTICE:
Don't try to shift to PARK (P) if your vehicle
is moving. If you do, you could damage the
transaxle. Shift to PARK (P) only when your
vehicle is stopped.

2-20 Starting Your Northstar V8 Engine
1. Without pushing the accelerator pedal, turn your
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive
heat can damage your starter motor. Wait about
15 seconds between each try to help avoid
draining your battery or damaging your starter.
2. If it doesn't start right away, hold your key in
START for about three seconds at a time until your
engine starts. Wait about 15 seconds between each
try to help avoid draining your battery or damaging
your starter.3. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for about three seconds. If the vehicle starts
briefly but then stops again, do the same thing.
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 don't,
your engine might not perform properly.
If you ever have to have your vehicle towed,
see the part of this manual that tells how to do
it without damaging your vehicle. See ªTowing
Your Vehicleº in the Index.
