You can use the DOME OVERRIDE button, located Mirrors
below the parking/headlamp knob, to set the dome
lamps to come
on automatically when the doors are Electrochromic Daymight Inside Rearview
opened, or to remain off. To turn the lamps off, press the Mirror

Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove
box and underhood lamps if they are left
on for more than
20 minutes when the ignition is off.
This will keep your battery from running down.
If the battery run-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return
to normal operation:
0 Shut off all lamps and close all doors, or
Turn the ignition key to RUN.
This mirror automatically changes to reduce glare from
headlamps behind you. A photocell on
the back of the
mirror senses when it is becoming dark outside. Another
photocell
built into the mirror surface senses when
headlamps are behind you.
At night, when the glare is too high, the mirror will
gradually darken
to reduce glare (this change may take a
few seconds). The mirror will return to its clear daytime
state when the glare
is reduced. The vehicle will also
return to its clear daytime state when the vehicle is put
into
REVERSE (R).

Accessory Power Outlets
With the accessory power outlets, you can plug in
auxiliary electrical equipment. There are four accessory
power outlets located throughout the vehicle. Two are
near the lower center part
of the instrument panel, one is
located in
the lower rear of the center console and the
other is located in
the rear of the vehicle in the air
inflator compartment. Follow the proper installation
instructions that are included with any electrical
equipment you install.
These circuits are protected by
a fuse and have
maximum current levels.
NOTICE:
When using the accessory power outlets,
maximum electrical load must not exceed

Decide which one of the three channels you want to
program. Using both hands, press the hand-held
transmitter button and the desired button
on the
universal transmitter. Continue
to hold both buttons
through Step
4.
Hold down both buttons until you see the red light

transmitter, make sure that you have followed the
directions exactly as described and that the battery
in the
hand-held transmitter is not dead. If you still cannot
program
it, rotate the hand-held transmitter end over end
and try again. The universal transmitter may not work
with older garage door openers that do not meet current
Federal Consumer Safety Standards.
If you cannot

your
GMC dealer. Be
sure to keep the original hand-held transmitter
in case you need to erase and reprogram the
universal transmitter.
Operating the Transmitter
Press and hold the appropriate button on the universal
transmitter. The red light comes on while the signal is
being transmitted.
Note that the effective transmission range of the
universal transmitter may differ from the hand-held
transmitter and from one channel to another.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you
if there is an electrical problem. The
system check includes
the air bag sensors, the air bag
module, the wiring and the diagnostic module. For more
information
on the air bag system, see “Air Bag” in
the Index.
This light will come on
when you start your engine,
and
it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your air bag
system may
not work properly. Have your vehicle
serviced right away.
The air bag readiness light should flash for a few
seconds when
you turn the ignition key to RUN. If the
light doesn’t come
on then, have it fixed so it will be
ready to warn
you if there is a problem.
Charging System Indicator Light
The charging system light
will come on briefly when
you turn on the ignition, but
’ the engine is not running,
as a check to show you it
is working.
It should go out once the engine
is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system.
It could indicate that
you have problems with
a generator drive belt, or
another electrical problem. Have
it checked right away.
Driving while this light
is on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.

Voltmeter Gage
I
When your engine is not
running, but the ignition is
on
(in RUN), this gage
shows your battery’s state of
charge in
DC volts.
When the engine is running,
the gage shows the
condition of
the charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings
in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition
is normal since the
charging system
is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings
in either warning zone indicate a possible
problem
in the electrical system. Have the vehicle
serviced as soon
as possible.

Theft-Deterrent Feature
THEFTLOCK@ is designed to discourage theft of your
radio.
It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored.
If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will
not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power has been interrupted. If your battery loses power
for any reason, you must unlock the radio with
the secret
code before
it will operate.
Activating the Theft-Deterrent Feature
The instructions which follow explain how to enter your
secret code to activate
the THEFTLOCK system. It is
recommended that you read through all nine steps
before starting
the procedure.
NOTE:
If you allow more than 15 seconds to elapse
between any steps, the radio automatically reverts to
time and you must start the procedure over at Step 4.

Understanding Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise
if you ever get it.
FM Stereo
FM stereo will give you the best sound, but FM signals
will reach
only about 10 to 40 miles (1 6 to 65 km). Tall
buildings or hills can interfere with
FM signals, causing
the sound to come and go.
Tips About Your Audio System
Hearing damage from loud noise is almost undetectable
until it is too late. Your hearing can adapt to higher
volumes
of sound. Sound that seems normal can be loud
and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to a safe
sound level before your hearing adapts to
it.
