Rear Door Security Locks
(Crew Cab)
If you have the crew cab model, your vehicle may be
equipped with rear door security locks. With this feature,
you can lock the rear doors so they cannot be opened
from the inside by passengers.
The security lock lever is
located on the inside edge
of each rear door.To use the security locks, do the following:
1. Open one of the rear doors.
2. Using your ignition key, turn the lock clockwise on
the driver’s side rear door, and counterclockwise on
the passenger’s side rear door to engage the
rear door security lock.
3. Close the door.
4. Repeat these steps on the opposite rear door.
If you want to open the rear door when the security lock is
on, unlock the door and open the door from the outside.
To return the rear doors to normal use, disengage the
locks by inserting the ignition key and turning the lock
counterclockwise for the driver’s side rear door, and
clockwise for the passenger’s side rear door.
Lockout Protection
If you have power door locks, this feature protects you
from locking your key in the vehicle when the key is
in the ignition and a door is open.
If the power door lock switch is pressed when a door is
open and the key is in the ignition, all of the doors will
lock and then the driver’s door will unlock.

controls are located on
the armrest of each door.
The driver’s door has switches for the passenger

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. However, there are ways you
can help.
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 door with the remote keyless entry
transmitter. The security light ashes.
If the vehicle is equipped with OnStar
®, and OnStar®
locks the doors, with all the doors closed, it will activate
the system.
2-14
Page 95 of 420

If the lock button on the remote keyless entry transmitter
is pressed, but a door is open, the horn will chirp six
times. Close the open door and the system will be
activated.
If a locked door is not opened with the remote keyless
entry transmitter, or OnStar
®, the alarm will go off.
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 won’t activate if
you lock the doors with a key, the manual door lock, or
power door lock switch. The system can only be activated
with the remote keyless entry transmitter, or OnStar
®.
You should also remember that you can start your vehicle
with the correct ignition key if the alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you don’t 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 a 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 won’t 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 5-104.
If the alarm does not sound or the headlamps do not
ash, see your dealer for service.

Passlock®
Your vehicle is equipped with 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 a correct key is not 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 key is turned
to RUN. SeeSecurity Light on page 3-35.
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 5-104. See your dealer for service.
In an emergency, call the GM 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 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 4-60for more information.
