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
If your vehicle has the
remote keyless entry
system, the vehicle has a
content theft-deterrent
alarm system.
To activate the content theft-deterrent system,
do the following:
1. Close all the doors.
2. Lock the doors with the remote keyless entry
transmitter. The security light, located on the
instrument panel cluster, will ash.
2-13
If the lock button on the remote keyless entry transmitter
is pressed, but a door is open, the horn will chirp
six times. Press the lock button again, within
three seconds, and the doors will lock. Close the
open door and the system will be activated.
If a locked door is not opened using the remote keyless
entry transmitter, or by OnStar
®, the pre-alarm will go
off. If the engine is not started or unlock not pressed
within 10 seconds, the front turn signal lamps will
ash for two minutes, and the horn will sound for
two minutes, then will turn off to save the battery power.
Remember, the theft-deterrent system will not activate
if you lock the doors with a key, the manual door lock, or
power door lock switch. The system can only be
activated using the remote keyless entry transmitter, or
by OnStar
®. SeeOnStar®System on page 2-38for
additional information. You should also remember that
you can start your vehicle with the correct ignition key if
the alarm has been set off.
Here is how 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 a door with the remote keyless entry
transmitter. Unlocking a door any other way will set
off the alarm.If you set off the alarm by accident, you can turn off the
alarm by pressing unlock on the remote keyless
entry transmitter. The alarm will not stop if you try to
unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, activate the system by
locking the doors with the remote keyless entry
transmitter.
2. Unlock the door with the manual door lock and
open the door. This should set off the alarm.
3. To turn the alarm off, press the unlock button on
the remote keyless entry transmitter or start the
engine.
If the alarm does not sound when it should but the lights
ash, check to see if the horn works. The horn fuse
may be blown. To replace the fuse, seeFuses
and Circuit Breakers on page 5-102.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer for service.
2-14
Passlock®
Your vehicle has the Passlock®theft-deterrent system.
Passlock
®is a passive theft-deterrent system.
Passlock®enables fuel if the ignition lock cylinder is
turned with a valid key. If an incorrect key is used or the
ignition lock cylinder is tampered with, the fuel system
is disabled and the vehicle will not start.
During normal operation, the security light will turn off
approximately ve seconds after the engine is started.
SeeSecurity Light on page 3-37.
If the engine stalls and the security light ashes, wait
about 10 minutes until the light stops ashing before
trying to restart the engine. Remember to release
the key from START as soon as the engine starts.
If the engine does not start after three tries, the vehicle
needs service.
If the engine is running and the security light comes on,
you will be able to restart the engine if you turn the
engine off. However, your Passlock
®system is
not working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
®at this
time. See your dealer for service.
In an emergency, call the Roadside Assistance Center.
SeeRoadside Assistance Program on page 7-6.
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:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake, or slow, the vehicle.
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 4-56for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.

Ignition Positions
With the key in the ignition
switch, you can turn to
four different positions.
LOCK (A):This position locks your ignition. It also
locks your transmission on automatic transmission
vehicles. It will lock your steering wheel on manual
transmission vehicles when the key is removed. It is a
theft-deterrent feature. You will only be able to
remove your key when the ignition is turned to LOCK.
If you have an automatic transmission, the ignition
switch cannot be turned to LOCK unless the shift lever
is in PARK (P).Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in.
If it is, turn the steering wheel left and right while
you turn the key hard. If none of this works,
then your vehicle needs service.
ACC (ACCESSORY) (B):This is the position in which
you can operate your electrical accessories or items
plugged into the accessory power outlets. On automatic
transmission vehicles, this position unlocks the
ignition. On manual transmission vehicles, it unlocks the
ignition and steering wheel. Use this position if your
vehicle must be pushed or towed.
ON (C):This is the position that the switch returns to
after you start your engine and release the switch.
The switch stays in ON when the engine is running.
But even when the engine is not running, you can use
ON to operate your electrical accessories and to display
some instrument panel cluster warning and indicator
lights. The transmission is also unlocked in this position
on automatic transmission vehicles.
2-16
START (D):This is the position that starts the engine.
When the engine starts, release the key. The ignition
switch will return to ON for normal driving.
When the engine is not running, ACC and ON allow you
to operate your electrical accessories, such as the
radio or items plugged into the accessory power outlets.
A warning tone will sound if you open the driver’s
door when the ignition is in ACC or LOCK and the key
is in the ignition.
Retained Accessory Power (RAP)
Your vehicle has Retained Accessory Power (RAP)
which will allow certain features of your vehicle
to continue working for up to 20 minutes after the
ignition key is turned to LOCK.
Your radio, wipers and power windows will work when
the ignition key is in ON or ACC. Once the key is turned
from ON to LOCK, these features will continue to
work for up to 20 minutes or until a door is opened.
Starting the Engine
Automatic Transmission
Move your shift lever to PARK (P) or NEUTRAL (N).
Your engine will not start in any other position — that is
a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.
Notice:Do not try to shift to PARK (P) if your
vehicle is moving. If you do, you could damage the
transmission. Shift to PARK (P) only when your
vehicle is stopped.
Manual Transmission
The gear selector should be in NEUTRAL and the
parking brake engaged. Hold the clutch pedal to the oor
and start the engine. Your vehicle will not start if the
clutch pedal is not all the way down — that is a safety
feature.
