Delayed Locking is activated when a door lock switch is
pressed while the key is not in the vehicle's ignition, and
a door is open. The door lock switch may be either the
lock switch on the door or on the remote keyless entry
transmitter (see ªRemote Keyless Entryº later in this
section for more details). The doors do not lock when
the lock switch is pressed, but instead, three chimes are
heard. These chimes indicate that the Delayed Locking
function has been activated.
You have three actions possible once Delayed Locking
is activated:

Cancel the Delayed Locking by pressing the unlock
switch or by fully inserting the key in the ignition.

Override the Delayed Locking feature and lock the
doors immediately by pressing the lock switch a
second time.

Let the Delayed Locking feature complete the
locking of the vehicle.
If you wish to let the Delayed Locking feature complete
the locking of the vehicle, no additional action is
required. The Delayed Locking feature will lock the
doors automatically after all the doors have been closed
for a period of five seconds. During this five second
period, any door may be reopened, at which time the
three possible actions shown above are again available.You may also customize your vehicle to activate the
Delayed Locking feature as described above, or you
may choose to completely disable the feature at all
times. If disabled, the power door locks will activate
immediately when a power door lock switch is pressed.

feature will be toggled when you perform the following
sequence with the doors closed and the ignition key
in RUN:

2. Press and hold the power door unlock switch. While
holding the door unlock switch, move the shift lever
out of and back into PARK (P).

will toggle the enable/disable state of the Delayed
Locking feature. During this procedure, the chime will
sound, providing you with feedback. In Mode1, a single
chime will be heard if the Delayed Locking feature is
disabled. In Mode 2, two chimes will be heard if the
feature is enabled. When the door unlock switch is
released, the vehicle will remain in the most recent
operating mode.
Disconnecting the vehicle battery for up to a year will
not change the programmed mode of the Delayed
Locking feature.

Illumination on Remote Activation
This feature provides interior lighting when a remote
keyless entry door unlock command is received and
executed by your vehicle. Your vehicle's ignition must
be off for the Illumination on Remote Activation feature
to work. The interior lamps will light until your
vehicle's ignition is turned to RUN or for a period of 40
seconds has elapsed. If a door is opened during this
period, the timed lighting will be canceled, and the
interior lamps will remain on since a door is open. Also
see ªPerimeter Lightingº in the Index.
Matching Transmitter(s) To Your Vehicle
Each remote keyless entry 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. Remember to bring any
remaining transmitters with you when you go to your
dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock your
vehicle. Each vehicle can have only four transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about three years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.

2-44 Delayed Headlamp Illumination
Delayed Headlamp Illumination provides a period of
exterior lighting as you leave your vehicle's area. The
feature is activated when your vehicle's headlamps are
on due to the automatic headlamp control feature
described previously in this section, and when your
vehicle's ignition is turned off. Your headlamps will
then remain on until the headlamp switch is moved from
OFF to the parking lamp position or until a 90 second
lighting period has ended.
If you turn off the ignition with the headlamp switch in
the parking lamp or headlamp position, the Delayed
Headlamp Illumination cycle will not occur.
You can customize the vehicle to activate Delayed
Headlamp Illumination when your vehicle's ignition is
turned off under the conditions described above, or you

6-35 Replacing Brake System Parts
The braking system on a vehicle is complex. Its many parts
have to be of top quality and work well together if the vehicle
is to have really good braking. Your vehicle was designed
and tested with top
-quality GM brake parts. When you
replace parts of your braking system
-- for example, when
your brake linings wear down and you have to have new ones
put in
-- be sure you get new approved GM replacement
parts. If you don't, your brakes may no longer work properly.
For example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and rear
brakes can change
-- for the worse. The braking performance
you've come to expect can change in many other ways if
someone puts in the wrong replacement brake parts.
Battery
Your new vehicle comes with an ACDelco Freedom

battery. When it's time for a new battery, we recommend
an ACDelco Freedom battery. Get one that has the
replacement number shown on the original
battery's label.
If your battery has a very low charge or is dead, you
may not be able to remove the ignition key from the
ignition switch or shift out of PARK (P). Refer to ªPark
Lock Systemº in the Index.
Vehicle Storage
If you're not going to drive your vehicle for 25 days or
more, remove the black, negative (
-) cable from the
battery. This will help keep your battery from
running down.
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº in the Index
for tips on working around a battery without
getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see ªTheft
-Deterrent
Featureº in the Index.
