Matching Transmitter(s) to Your
Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter
is lost or stolen, a replacement can be purchased
through your dealer/retailer. All transmitters need to be
re-coded to match the new transmitter.The lost transmitter will no longer work after the new
transmitters are re-coded. The vehicle can have a
maximum of eight transmitters matched to it. See
“Relearn Remote Key” underDIC Operation and
Displays (With DIC Buttons) on page 3-57orDIC
Operation and Displays (Without DIC Buttons) on
page 3-63for instructions on how to match RKE
transmitters to your vehicle.
Battery Replacement
Replace the battery if the REPLACE BATTERY IN
REMOTE KEY message displays in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” underDIC
Warnings and Messages on page 3-66for 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.

The RKE transmitter with the remote start button,
provides an increased range of operation. However, the
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 turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote Keyless
Entry (RKE) System on page 2-4for additional
information.
/(Remote Start):This button will be on the RKE
transmitter if you have remote start.
To start the vehicle:
1. Aim the transmitter at the vehicle.
2. Press and release the transmitter’s lock button, then
immediately press and hold the transmitter’s remote
start button until the turn signal lights ash. If you
cannot see the vehicle’s lights, press and hold the
remote start button for at least four seconds. The
vehicle’s doors will lock. Pressing the remote start
button again, after the vehicle has started, will shut
the vehicle off.
When the vehicle starts, the parking lamps will turn
on and remain on while the vehicle is running.3. If it is the rst remote start since the vehicle has
been driven, repeat these steps while the engine
is still running, to extend the time by 10 minutes for
the engine to continue to run. Remote start can
be extended one time.
After entering the vehicle during a remote start, insert
and turn the key to the ON/RUN position to drive
the vehicle.
If the vehicle is left running it will automatically shut off
after 10 minutes unless a time extension has been done.
To manually shut off a remote start:
Aim the RKE transmitter at the vehicle and press
the remote start button until the parking lamps
turn off.
Turn on the hazard warning ashers.
Turn the ignition switch on and then off.
The vehicle can be started using the remote start
feature two separate times between driving sequences.
The engine will run for 10 minutes after each remote
start.
Or, you can extend the engine run time by another
10 minutes within the rst 10 minute remote start time
frame, and before the engine stops.

Outside Power Mirrors
If your vehicle is equipped
with outside power mirrors,
the controls are located
on the driver’s door
armrest.
Press (A) to select the driver’s side mirror or (B) to
select the passenger’s side mirror. Press either (A) or
(B) again to deselect the mirror.
To adjust each mirror, press one of the four arrows
located on the control pad to move the mirror in
the direction you want it to go. Adjust each outside
mirror so that you can see a little of your vehicle, and
the area behind your vehicle. SeeMemory Seat
and Mirrors on page 1-6for more information.The mirrors can be manually folded inward to prevent
damage when going through an automatic car wash. To
fold, push the mirror toward the vehicle. To return the
mirror to its original position, push outward. Be sure
to return both mirrors to their original unfolded position
before driving.
The use of hood-mounted air deectors and add-on
convex mirror attachments may adversely affect mirror
performance.
Turn Signal Indicator
Your vehicle may have a turn signal indicator on the
mirror. An arrow on the mirror will ash in the direction
of the turn or lane change.
2-42

Park Tilt Mirrors
If your vehicle has the memory package, the outside
mirrors are able to perform the park tilt function. This
feature may be useful in allowing the driver to view the
curb when parallel parking. This feature will cause the
passenger’s and/or driver’s mirror to tilt to a preselected
position when the vehicle is in REVERSE (R).
The passenger’s and/or driver’s mirror will return to its
original position when the vehicle is shifted out of
REVERSE (R), or the ignition is turned off or to
OFF/LOCK.
This feature can be turned on or off through the Driver
Information Center (DIC). SeeDIC Vehicle
Customization (With DIC Buttons) on page 3-75and
Memory Seat and Mirrors on page 1-6for more
information.
Turn Signal Indicator
Your vehicle may have a turn signal indicator on the
mirror. An arrow on the mirror will ash in the direction
of the turn or lane change.
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’s side mirror may have convex glass. A
convex mirror’s surface is curved so more can be
seen from the driver’s seat.
Outside Heated Mirrors
Press the rear window defogger button, located on the
climate control panel, to also turn the outside heated
mirrors on or off. The mirrors will heat to help clear fog
or frost from the surface of the mirror.
See “Rear Window Defogger” underDual Automatic
Climate Control System on page 3-29for more
information.

When the System Does Not Seem to
Work Properly
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep your
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-92.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your liftgate
during your last drive cycle, the red light may
illuminate in the rear display. Once the attached
object is removed, URPA will return to normal
operation.
A tow bar is attached to your vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take your vehicle to your
dealer/retailer.
Rear Vision Camera
Your vehicle may have a Rear Vision Camera system.
Read the entire section before using the system.
The rear vision camera system is designed to help the
driver when backing up. See “Rear Vision Camera”
in the Index of the navigation manual.
OnStar®System
OnStar uses several innovative technologies and live
advisors to provide you with a wide range of safety,
security, information, and convenience services. If your
airbags deploy, the system is designed to make an
automatic call to OnStar Emergency advisors who can

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-heldtransmitter 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.
5. Press and hold the newly-trained Universal Home
Remote button and observe the indicator light.
If the indicator light stays on continuously,
the programming is complete and your garage door
should move when the Universal Home Remote
button is pressed and released. You do not need to
continue the programming Steps 6 through 8 and
can stop here.
If the Universal Home Remote indicator light blinks
rapidly for two seconds and then turns to a
constant light, continue with the programming Steps
6 through 8.
It may be helpful to have another person available
to assist with the remaining steps.
