2007 GMC YUKON XL battery replacement

At times you may notice a decrease in operating
range. This is normal for any remote keyless entry
system. If the transmitter does not work or if you
have to stand closer to your vehicle for the
transmitter to work, try this:
Check the distance. You may be too far from
your vehicle. You may need to stand closer
during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 113.
If you are still having trouble, see your dealer or
a qualied technician for service.
Remote Keyless Entry System
Operation
The vehicle’s doors can be locked and unlocked
from about 3 feet (1 m) up to 65 feet (20 m)
away with the Remote Keyless Entry (RKE)
transmitter.
If your vehicle has the remote start feature you can
also start your vehicle with the RKE transmitter.
The RKE transmitter, with the remote start button,
provides an increased operating range of 195 feet
(60 m) away. However, the operating range may be
less while the vehicle is running. As a result, you
may need to be closer to your vehicle to turn it off
than you were to start it.
There are other conditions which can affect the
performance of the transmitter. SeeRemote
Keyless Entry System on page 112.

Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about four years.
You can tell the battery is weak if the transmitter
will not work at the normal range in any location.
If you have to get close to your vehicle before
the transmitter works, it is probably time to change
the battery.
The REPLACE BATTERY IN REMOTE KEY
message in the vehicle’s DIC will display if the
RKE transmitter battery is low. See “REPLACE
BATTERY IN REMOTE KEY” underDIC Warnings
and Messages on page 254for additional
information.
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.To replace the battery in the RKE transmitter do
the following:
1. Use a at object with a thin edge into the
notch, located below the trunk release
button, and separate the bottom half from the
top half of the transmitter.
2. Remove the old battery, but do not use a
metal object to do this.

Headphones
The RSE includes two 2–channel wireless
headphones that are dedicated to this system.
These headphones are used to listen to media
such as CDs, DVDs, MP3s, DVDAs, radio, or any
auxiliary source connected to the auxiliary input
jack, if your vehicle has this feature or A/V
jacks. The wireless headphones have an ON/OFF
button channel 1/2 switch, and a volume control.
If your vehicle has a third row video screen
display, it will have two additional headphones.Push the power button to turn on the headphones.
An indicator light located on the headphones
will illuminate. If the light does not illuminate, the
batteries may need to be replaced. See “Battery
Replacement” later in this section for more
information. Switch the headphones to OFF when
not in use. Channel 1 is dedicated to the video
screen, while Channel 2 is dedicated to RSA
selections.
The infrared transmitters are located at the rear of
the RSE overhead console. The headphones
will shut off automatically to save the battery power
if the DVD system is shut off or if the headphones
are out of range of the transmitters for more
than 3 minutes. If you move too far forward or step
out of the vehicle, the headphones will lose the
audio signal.
The headphones will automatically turn off after
4 hours of continuous use.
To adjust the volume on the headphones, use the
volume control located on the right side.
For optimal audio performance, the headphones
must be worn correctly. The symbol L (Left)
will appear on the upper left side, above the ear
pad and should be positioned on the left ear.

The symbol R (Right) will appear on the upper
right side, above the ear pad and should be
positioned on the right ear.
Notice:Do not store the headphones in heat
or direct sunlight. This could damage the
headphones and repairs will not be covered by
your warranty. Keep the headphones stored
in a cool, dry place.
The foam ear pads attached to the headphones
may become worn or damaged if they are
not handled or stored properly. If the foam ear
pads do become damaged or worn out, the pads
can be replaced separately from the headphone
set. It is not necessary to replace the complete
headphone set. The headphone replacement foam
ear pads can be ordered in pairs. See your
dealer for more information.Battery Replacement
To change the batteries, do the following:
1. Turn the screw with a coin or screw driver to
loosen, then slide open the battery door
located on the left side of the headphones.
2. Replace the two AAA batteries in the
compartment. Make sure that they are
installed correctly, using the diagram on the
inside of the battery compartment.
3. Replace the battery door and tighten the door
screw.
If the headphones are to be stored for a long
period of time, remove the batteries and keep them
in a cool, dry place.

screen, as damage may occur. See “Cleaning
the Video Screen” later in this section for
more information.

window at the rear of the RSE overhead console
and press the desired button. Direct sunlight
or very bright light may affect the ability of the RSE
transmitter to receive signals from the remote

working, the batteries may need to be replaced.
See “Battery Replacement” later in this section.
Objects blocking the line of sight may also affect
the function of the remote control.
If a CD or DVD is in the Radio DVD slot, the
remote control power button can be used to turn
on the video screen display and start the disc.
The radio can also turn on the video screen
display. SeeRadio with CD and DVD (MP3) on
