2004 GMC ENVOY XL audio

Radio Personalization
If your vehicle has this feature, it allows the driver to
return to the last used source: radio, cassette, or
CD using the remote keyless entry transmitter. This
feature can also store and recall AM and FM presets,
volume, tone, and the last selected radio station.
The number on the back of each transmitter, 1 or 2,
corresponds to driver 1 or 2. If transmitter 1 is used to
enter the vehicle, the last used audio source and/or
settings set by driver 1 will be recalled. If transmitter 2
is used to enter the vehicle, the last used audio
source and/or settings set by driver 2 will be recalled.
Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
vehicle’s radio. The feature works automatically by
learning a portion of the Vehicle Identication Number
(VIN). If the radio is moved to a different vehicle, it
will not operate and LOCKED will appear on the display.
When the radio and vehicle are turned off, the blinking
red light indicates that THEFTLOCK
®is armed.
With THEFTLOCK
®activated, the radio will not operate
if stolen.
Audio Steering Wheel Controls
Some audio controls can be adjusted at the steering
wheel. They include the following:
g(OnStar/Voice Recognition):If your vehicle has
OnStar®, press this button to interact with the OnStar®
system. See the OnStar®manual provided with your
vehicle for more information.
If your vehicle does not have OnStar
®, press this button
to silence the system. Press it again, or any other
radio button, to turn on the sound.

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 need new ones put in — be sure
you get new approved GM replacement parts. If you do
not, 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 have come to expect can change
in many other ways if someone puts in the wrong
replacement brake parts.
Battery
Your new vehicle comes with a maintenance free
ACDelco®battery. When it is time for a new battery,
get one that has the replacement number shown on the
original battery’s label. We recommend an ACDelco
®
battery. SeeEngine Compartment Overview on
page 5-12for battery location.Warning:Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
Vehicle Storage
If you are 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
are not careful. SeeJump Starting on page 5-43
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, seeTheft-Deterrent
Feature on page 3-119.
