to OFF.
The temperature display will remain in its current
state each time the ignition goes through its cycle.
At start up, if the vehicle has been off for less
than two and a half hours, and the last stored
temperature was less than the current termperature,
the sensor will increase 1°F every two minutes
until the correct temperature is displayed.
If the vehicle has been off more than two and a
half hours, or the last stored temperature is
greater than the current temperature, the current
temperature immediately displays.
If the temperature is 37°F (3°C) or lower, ICE will
ash on the temperature display. This display will
ash every two seconds for a period of one minute.
If an abnormal temperature reading is displayed for
an extended period of time, see your dealer/retailer.
Under certain circumstances, a delay in updating
the temperature is normal.

Outside Convex Mirror
{CAUTION:
A convex mirror can make things (like other
vehicles) look farther away than they really are.
If you cut too sharply into the right lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
The passenger side mirror is convex. A convex mirror’s
surface is curved so more can be seen from the
driver seat. It also makes things, like other vehicles,
look farther away than they really are.
Object Detection Systems
Rear Vision Camera
Your vehicle may be equipped with a rear vision camera
system. Read this entire section before using the
camera system.
The rear vision camera system is designed to help the
driver when backing up by displaying a view of the area
behind the vehicle. When the driver shifts the vehicle into
REVERSE (R), the video screen will automatically slide
out from the rear view mirror. Once the driver shifts out of
REVERSE (R), the video screen will slide back into the
rear view mirror after a delay.
The display has a guideline overlay that can help the
driver align the vehicle when backing into a parking spot.
To turn off the rear vision camera system, do the
following:
1. Place the vehicle shift lever in PARK (P).
2. Turn the ignition key to the ACCESSORY position.
3. Press the right mirror button briey; the right
green light indicator will turn off. The rear camera
vision display is now disabled.
2-44

To turn on the rear camera vision feature again, press
the right mirror button briey. The green light indicator
will illuminate. The rear camera vision system is
now enabled and the display will slide out from the
mirror normally.
To manually slide out the rear camera screen for
cleaning, do the following:
1. Place the vehicle shift lever in PARK (P).
2. Turn the ignition key to the ACCESSORY or
RUN position.
3. Press and hold the right mirror button for
ve seconds. The display will slide out from
the mirror for 30 seconds; the right green LED
indicator will remain illuminated. The camera
screen will not be on when it slides out of
the mirror.
4. If additional time is required for cleaning,
repeat step 3.
To resume normal operation, press the right button
momentarily while the rear camera screen is out or wait
30 seconds for screen to slide back into the mirror.
For more information on the automatic dimming,
compass, and temperature features of the mirror, see
Automatic Dimming Rearview Mirror with Compass
and Temperature Display on page 2-41.
{CAUTION:
The Rear Vision Camera (RVC) system does
not replace driver vision. RVC does not:
Detect objects that are outside the
camera’s eld of view, below the bumper,
or underneath the vehicle.
Detect children, pedestrians, bicyclists,
or pets.
Do not back the vehicle by only looking at the
rear vision camera screen, or use the screen
during longer, higher speed backing maneuvers
or where there could be cross-traffic. Your
judged distances using the screen will differ
from actual distances.
So if you do not use proper care before backing
up, you could hit a vehicle, child, pedestrian,
bicyclist, or pet, resulting in vehicle damage,
injury, or death. Even though the vehicle has
the RVC system, always check carefully before
backing up by checking behind your vehicle.

When the System Does Not Seem To
Work Properly
The rear vision camera system may not work properly
or display a clear image in the following situations:
In the dark.
When the sun or the beam of headlights is shining
directly into the camera lens.
If ice, snow, mud, or anything else builds up on
the camera lens. Clean the lens, rinse it with
water, and wipe it with a soft cloth.
If the back of the vehicle is in an accident, the
position and mounting angle of the camera
may change or the camera may be affected.
Be sure to have the camera and its position
and mounting angle checked at your dealer.
Extreme high or low temperatures or extreme
temperature changes can affect the image
displayed.

Your Responsibility
You may need to increase the volume of your radio
to hear the OnStar advisor. If the light next to the OnStar
buttons is red, this means that your system is not
functioning properly and should be checked by a dealer.
If the light appears clear (no light is appearing), your
OnStar subscription has expired. You can always press
the blue OnStar button to conrm that your OnStar
equipment is active.

Universal Home Remote System
Operation (With One Triangular LED)
If there is one triangular Light Emitting Diode (LED)
indicator light above the Universal Home Remote
buttons, follow the instructions below.
This system provides a way to replace up to three
remote control transmitters used to activate devices
such as garage door openers, security systems,
and home automation devices.
Do not use the Universal Home Remote with any
garage door opener that does not have the stop and
reverse feature. This includes any garage door opener
model manufactured before April 1, 1982.Read the instructions completely before attempting to
program the Universal Home Remote. Because of
the steps involved, it may be helpful to have another
person available to assist you in the programming
the Universal Home Remote.
Keep the original hand-held transmitter for use in other
vehicles as well as for future Universal Home Remote
programming. It is also recommended that upon the
sale of the vehicle, the programmed Universal Home
Remote buttons should be erased for security purposes.
See “Erasing Universal Home Remote Buttons” later
in this section.
When programming a garage door, park outside of
the garage. Park directly in line with and facing
the garage door opener motor-head or gate motor-head.
Be sure that people and objects are clear of the
garage door or gate you are programming.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.

Programming the Universal Home
Remote System
If you have questions or need help programming the
Universal Home Remote System, call 1-800-355-3515
or go to www.homelink.com.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these actions,
the device will time out and you will have to repeat
the procedure.
To program up to three devices:
1. From inside the vehicle, press and hold down the
two outside buttons at the same time, releasing
only when the Universal Home Remote indicator
light begins to ash, after 20 seconds. This step
will erase the factory settings or all previously
programmed buttons.Do not hold down the buttons for longer than
30 seconds and do not repeat this step to program
the remaining two Universal Home Remote
buttons.
2. Hold the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the Universal
Home Remote buttons while keeping the indicator
light in view. The hand-held transmitter was supplied
by the manufacturer of your garage door opener
receiver (motor head unit).
3. At the same time, press and hold both the
Universal Home Remote button that you would
like to use to control the garage door and the
hand-held transmitter button. Do not release the
Universal Home Remote button or the hand-held
transmitter button until Step 4 has been completed.
Some entry gates and garage door openers
may require you to substitute Step 3 with the
procedure noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light on the Universal Home Remote
will ash slowly at rst and then rapidly after
Universal Home Remote successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
