If a door is open or ajar when the lock button
is pressed, the horn will chirp several times to let
you know the doors did not lock and the content
theft-deterrent system is not armed. Pressing
the lock button again while the horn is chirping
or within three seconds after the horn stops
sounding, the doors will lock but the content
theft-deterrent system will not arm until the
opened door is closed.
You can program different feedback modes
through the Driver Information Center (DIC).
To program the feedback modes, see “Remote
Keyless Entry Feedback” underDIC Controls

Matching Transmitter(s) to
Your Vehicle
Each RKE transmitter is coded to prevent
another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement
can be purchased through your dealer/retailer.
Remember to bring any remaining transmitters
with you when you go to your dealer/retailer.
When the dealer/retailer matches the replacement
transmitter to your vehicle, any remaining
transmitters must also be matched. Once your
dealer/retailer has coded the new transmitter,
the lost transmitter will not unlock your
vehicle. Each vehicle can have a maximum
of four transmitters matched to it.

Passengers, especially children,
can easily open the doors and fall out
of a moving vehicle. When a door is

thrown out of the vehicle in a crash
if the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.

CAUTION: (Continued)
Young children who get into unlocked
vehicles may be unable to get out.
A child can be overcome by extreme
heat and can suffer permanent injuries
or even death from heat stroke.
Always lock your vehicle whenever
you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors
can help prevent this from happening.

Programmable Automatic
Door Locks
If your vehicle has power door locks and the
remote keyless entry system, it has an automatic
lock/unlock feature.
If your vehicle has an automatic transmission,
it is programmed from the factory to lock all doors
automatically when the shift lever is moved out
of PARK (P). All the doors will unlock when
the shift lever is moved back into PARK (P).
If your vehicle has a manual transmission, it is
programmed from the factory to lock all the
doors when the vehicle speed is greater than
15 mph (24 km/h). The doors will unlock when
the key is removed from the ignition.
To change the automatic door lock and unlock
settings, see “Automatic Door Locks” under
DIC Controls and Displays on page 198.
Rear Door Security Locks
(Crew Cab)
If your vehicle is a crew cab model, it may have
rear door security locks. With this feature, you can
lock the rear doors so they cannot be opened
from the inside.
The rear door security
lock is located on
the inside edge of each
rear door below the
security lock label.

Power Windows
{CAUTION:
Leaving children, helpless adults, or pets
in a vehicle with the windows closed is
dangerous. They can be overcome from
extreme heat in warm or hot weather and
suffer permanent injuries or even death
from heat stroke.
Leaving children in a vehicle with the
ignition key is dangerous for many
reasons, children or others could be badly
injured or even killed. They could operate
the power windows or other controls or
even make the vehicle move. The windows
will function with the keys in the ignition
and they could be seriously injured or killed
if caught in the path of a closing window.
Do not leave keys in a vehicle with children.
When there are children in the rear seat
use the window lockout button to prevent
unintentional operation of the windows.The power window
switches for all windows
are located on the
driver’s door armrest.
In addition, each
passenger’s door has
its own switch.
The power windows will work when the ignition
is in ACC (Accessory) or ON or while Retained
Accessory Power (RAP) is active. SeeRetained
Accessory Power (RAP) on page 121.
Pull the front of the switch up to raise the window.

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 (RKE) system,
the vehicle has a
content theft-deterrent
alarm system.
To activate the content theft-deterrent system:
1. Close all the doors.
2. Lock the doors with the RKE transmitter.
The security light, located on the instrument
panel cluster, will ash.
If the lock button on the RKE 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.
115
Page 116 of 496

If a locked door is not opened using the RKE
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
RKE transmitter, or by OnStar
®. SeeOnStar®
System on page 149for 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 RKE 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 RKE
transmitter. The alarm will not stop if you try to
unlock a door any other way.
Testing the Alarm
To test the alarm:
1. From inside the vehicle, activate the system
by locking the doors with the RKE 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 RKE 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 433.
If the alarm does not sound or the front turn signal
lamps do not ash, see your dealer/retailer for
service.
