Radio Signals for Canada and
Some Gate Operators
For questions or programming help
call 1-800-355-3515 or see
www.homelink.com.
Canadian radio-frequency laws and
some U.S. gate operators require
transmitter signals to time out or quit
after several seconds of
transmission. This may not be long
enough for the Universal Remote
system to pick up the signal during
programming.
If the programming did not work,
replace Step 2 under“Programming
the Universal Remote System” with
the following:
Press and hold the Universal
Remote system button while
pressing and releasing the
hand-held transmitter button every
two seconds until the signal has
been successfully accepted by the
Universal Remote system. The
Universal Remote system indicator light will flash slowly at first and then
rapidly. Proceed with Step 3 under
“Programming the Universal Remote
System”
to complete.
Universal Remote System
Operation
Using the Universal Remote
System
Press and hold the appropriate
Universal Remote system button for
at least one-half second. The
indicator light will come on while the
signal is being transmitted.
Erasing Universal Remote
System Buttons
Erase all programmed buttons when
vehicle ownership is terminated.
To erase:
1. Press and hold the two outside buttons until the indicator light
begins to flash. This should
take about 10 seconds.
2. Release both buttons.
Reprogramming a Single
Universal Remote System
Button
To reprogram any of the system
buttons: 1. Press and hold any one of the buttons. Do not release the
button.
2. The indicator light will begin to flash after 20 seconds. Without
releasing the button, proceed
with Step 1 under
“Programming the Universal
Remote System.”

Climate Controls 161
Caution
Do not try to clear frost or other
material from the inside of the
front windshield and rear window
with a razor blade or anything
else that is sharp. This may
damage the rear window
defogger grid and affect the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.
Heated and Ventilated Front Seats
(If Equipped) : Press
MorLto
heat the driver or passenger seat
cushion and seatback.
Press
Cor{, if equipped, to
ventilate the driver or passenger
seat. See Heated and Ventilated
Front Seats 056. Remote Start Climate Control
Operation (If Equipped) :
If the
vehicle is equipped with the remote
start feature, the climate control
system may run when the vehicle is
started remotely. The system uses
the driver ’s previous settings to heat
or cool the inside of the vehicle. The
rear defog may come on during
remote start based on cold ambient
conditions. If the vehicle has heated
or ventilated seats, they may come
on during a remote start. See
Remote Vehicle Start 034 and
Heated and Ventilated Front
Seats 056.
Sensor
The solar sensor, on top of the
instrument panel near the
windshield, monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise
the automatic climate control system
may not work properly.
Air Vents
Use the louvers on the air vents to
change the direction of the airflow.
To open the vent, move the
thumbwheel to
t. To close the vent,
move the thumbwheel to
l.
For vehicles with eAssist, there is a
battery cooling air vent on the shelf
behind the rear passenger seats
below the rear window. Keep this air
inlet clear from items that may block
airflow. Proper airflow is required to
keep the eAssist battery and control
system cool.
Operation Tips
. Keep all outlets open whenever
possible for best system
performance.
. Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
. Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
