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 content theft-deterrent
alarm system.
The security light is
located on the
instrument panel cluster.To operate the system, do the following:
1. Open the door.
2. Lock the door with the power door lock switch
or the Remote Keyless Entry (RKE)
transmitter. The security light should ash.
3. Close all doors. The security light should turn
off after about 30 seconds. The alarm is not
armed until the security light turns off.
If a locked door is opened without the key or
the RKE transmitter, the alarm will go off.
The headlamps and parking lamps will ash for
two minutes, and the horn will sound for
30 seconds, 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 or use the
manual door lock. It activates only if you use a
power door lock switch with the door open, or with
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.
110

To avoid setting off the alarm by accident, do the
following:
Always lock the vehicle using the door key
afterthe doors are closed.
Always unlock a door with a key, or use the
RKE transmitter. Unlocking a door any other
way will set off the alarm.
If you set off the alarm by accident, unlock any
door with the key. You can also turn off the alarm
by pressing unlock on the RKE transmitter.
The alarm will not stop if you try to unlock a door
any other way.
Testing the Alarm
To test the alarm, do the following:
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.When the alarm is set the power door unlock
switch will not work.
If the alarm does not sound when it should but the
headlamps ash, check to see if the horn works.
The horn fuse may be blown. To replace the fuse,
seeFuses and Circuit Breakers on page 493.
If the alarm does not sound or the headlamps do
not ash, the vehicle should be serviced by
your dealer.
Passlock®
Your vehicle has the Passlock®theft-deterrent
system.
Passlock
®is a passive theft-deterrent system that
enables fuel if the ignition lock cylinder is turned
with a valid key. If a correct key is not used or the
ignition lock cylinder has been tampered with, the
fuel system is disabled and the vehicle will not start.
During normal operation, the security light will
turn off about ve seconds after the key is turned
to RUN.
111

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. You
may also want to check the fuse. SeeFuses and
Circuit Breakers on page 493. See your dealer
for service.
In an emergency, call the GM Roadside
Assistance Center. SeeRoadside Assistance
Program on page 532.
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. See
Towing a Trailer on page 362for the trailer
towing capabilities of your vehicle and more
information.
Following break-in, engine speed and load can
be gradually increased.
