Programming the Universal
Remote System
For questions or programming help,
see www.homelink.com/gm or call
1-800-355-3515. For calls placed
outside the U.S., Canada, or Puerto

and may differ based on landline or
mobile phone.
Programming involves
time-sensitive actions, and may time
out causing the procedure to be
repeated.
To program up to three devices:1. Hold the end of the hand-held transmitter about 3 to 8 cm (1
to 3 in) away from the
Universal Remote system
buttons with the indicator light
in view. The hand-held
transmitter was supplied by the
manufacturer of the garage
door opener receiver. 2. At the same time, press and
hold both the hand-held
transmitter button and one of
the three Universal Remote
system buttons to be used to
operate the garage door. Do
not release either button until
the indicator light goes from a
slow to a rapid flashing light.
Then release both buttons.
Some garage door openers
may require substitution of
Step 2 with the procedure
under “Radio Signals for Some
Gate Operators” later in this
section.
3. Press and hold the newly programmed Universal Remote
system button for five seconds
while watching the indicator
light and garage door
activation.
.If the indicator light stays on
continuously or the garage
door moves when the
button is pressed, then
programming is complete.
There is no need to
complete Steps 4–6. .
If the indicator light does
not come on or the garage
door does not move, a
second button press may
be required. For a second
time, press and hold the
newly programmed button
for five seconds. If the light
stays on or the garage door
moves, programming is
complete.
. If the indicator light blinks
rapidly for two seconds,
then changes to a solid light
and the garage door does
not move, continue with
programming Steps 4–6.

Battery Load
Management
The vehicle has Electric Power
Management (EPM), which
estimates the battery's temperature
and state of charge. It then adjusts
the voltage for best performance
and extended life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up.
When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. The voltmeter
gauge or the voltage display on the
Driver Information Center (DIC),
if equipped, may show the voltage
