certain diagnostic information and can
tell you how serious the problem is and

SAFETY & SECURITY

(if equipped)
The Remote Keyless Entry (RKE) trans-
mitter includes the following functions:
(Lock):Press this button once to
lock all the doors. RKE feedback
can be programmed using the Driver
Information Center (DIC).
(Unlock):Press this button once to

ton again within five seconds to unlock

(Vehicle Locator/Panic Alarm):
Press this button while the ignition is
turned off to locate your vehicle or acti-
vate the alarm. Briefly press the button

the vehicle.
If you notice a decrease in the range of

• Check the distance. You may be too
far from your vehicle, especially
during rainy or snowy weather.
• Check the location. Other vehicles or
objects may be blocking the signal.
Note:Your vehicle’s warnings and mes-
sages provide critical information that
can prevent damage to your vehicle.
Review your Owner Manual to become
familiar with the information displayed
and the action required.

• Check to determine whether battery
replacement or resynchronization is
necessary.
See Section 2 of your Owner Manual.
Note:The RKE system will not operate
if the hood is open or if the key is in the
ignition.
PASS-Key®III Theft-Deterrent
System
Your vehicle is equipped with the
PASS-Key III theft-deterrent system,
which is a passive system that disables
the vehicle’s starter and fuel system if
someone attempts to start the vehicle
without the correct key.
During normal operation, the
(Security) light will turn off approximately
five seconds after the key is turned to
Run.
If the security light turns on while driving
and stays on, there may be a problem
with the PASS-Key III system. You will
be able to restart the engine if you turn
off the engine; however, your vehicle will
not be protected by PASS-Key III and
you should see your GM dealer.
See Section 2 of your Owner Manual.
Door Locks
Lockout Protection
This feature protects you from locking
the vehicle with the key in the ignition.
If the power door lock switch is pressed
when either the driver’s, passenger’s
or rear doors are open, all of the doors
will lock and then the driver’s door will
unlock. This feature does not include the
side cargo door.Cargo Door Relocking
This feature secures the side cargo
door after unloading cargo. If the side
cargo door is open when the Lock button
on the power door lock switch or the
Remote Keyless Entry transmitter is
pressed, all doors will lock and then
relock after the side cargo door is
closed. The side cargo door must be
closed within several minutes for the
relock to occur.
Security Locks (if equipped)
Security locks can be engaged on the
passenger-side rear door, the side
sliding door and the driver-side and
passenger-side 60/40 swing-out side
doors so that passengers can’t open the
doors from the inside.
To engage the security locks, move the
lever on the door to the (Lock) posi-
tion. Move it to the (Unlock) position
to return the doors to normal operation.See Section 2 of your Owner Manual.
