Compass Variance
The zone is set to zone eight upon leaving the factory.
It will be necessary to adjust the compass to
compensate for compass variance if you live outside
zone eight. Under certain circumstances, as during
a long distance cross-country trip, it will be necessary to
adjust for compass variance. Compass variance is
the difference between earth’s magnetic north and true
geographic north. If not adjusted to account for
compass variance, your compass could give false
readings.
To adjust for compass variance do the following:
1. Find the current location and variance zone number
on the following zone map.
2. Press and hold the on/off button until a zone
number appears in the display.
3. Once the zone number appears in the display,
press the on/off button quickly until the correct
zone number appears in the display. Stop pressing
the button and the mirror will return to normal
operation. If C appears in the compass window, the
compass may need calibration. SeeCompass
Calibrationlisted previously.

Cleaning the Mirror
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
Outside Power Mirrors
The control on the driver’s
door armrest operates both
outside rearview mirrors.
Press (R) on the selector switch to choose the right
mirror or (L) to choose the left mirror. The center position
is off and will not allow the mirrors to move if the
control pad is touched.To adjust a mirror, press the arrows on the control pad
to move the mirror in the direction you want the mirror
to go. Adjust each mirror so you can see the side of your
vehicle and the area behind your vehicle.
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 positions
before driving.
The mirrors also have an arrow on the mirror face that
ashes in the direction of the turn when the turn signal
is used. SeeTurn Signal/Multifunction Lever on
page 3-8.
The mirrors can also be programmed for personalization
and the parallel parking feature if you have the
optional memory package. For more information, see
Memory Seat, Mirrors and Steering Wheel on page 2-53
andDIC Vehicle Personalization on page 3-68.

Outside Automatic Dimming Mirror
If the vehicle is equipped with this feature, the driver’s
side mirror will adjust for the glare of headlamps behind
you. This feature is controlled by the on and off
settings on the automatic dimming rearview mirror.
SeeAutomatic Dimming Rearview Mirror with OnStar
®
on page 2-37.
Outside Curb View Assist Mirror
If your vehicle is equipped with memory mirrors, it will
also be capable of performing the curb view assist mirror
feature. This feature will allow the passenger’s side
mirror to tilt to a factory programmed position when the
vehicle is in REVERSE (R). This feature may be
useful in allowing you to view the curb when you are
parallel parking.
When the vehicle is shifted out of REVERSE (R) and
a ve-second delay has occurred, the passenger’s side
mirror will return to its original position.
If further adjustment is needed after the mirror is tilted,
the mirror switch may be used.
This feature can be enabled/disabled through the
Driver Information Center (DIC). SeeDIC Vehicle
Personalization on page 3-68for more information.
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 is convex. A convex mirror’s
surface is curved so more can be seen from the
driver’s seat. This mirror does not have a dimming
feature.
Outside Heated Mirrors
When you operate the rear window defogger, it also
warms both outside mirrors to help clear them of fog or
ice. SeeDual Climate Control System on page 3-30
for more information.

HomeLink®Wireless Control
System Operation
Do not use the HomeLink®Transmitter 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. If you have a newer
garage door opener with rolling codes, please be
sure to follow Steps 6 through 8 to complete the
programming of your HomeLink
®Transmitter.
Read the instructions completely before attempting to
program the HomeLink
®Transmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.Keep the original transmitter for use in other vehicles as
well as for future HomeLink
®programming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
®buttons should be erased
for security purposes. Refer to “Erasing HomeLink®
Buttons” or, for assistance, contact HomeLink®on the
Internet at: www.homelink.com or by calling
1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio frequency.

Programming HomeLink®
Your vehicle’s engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the indicator light begins to
ash, after 20 seconds. Do not hold down the
buttons for longer than 30 seconds and do not
repeat this step to program a second and/or third
transmitter to the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
®
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
®and the hand-held transmitter
button. Do not release the buttons 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 will ash slowly at rst and then
rapidly after HomeLink
®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
®button
and observe the indicator light.
If the indicator light stays on constantly, programming
is complete and your device should activate when the
HomeLink
®button is pressed and released.
To program the remaining two HomeLink®buttons,
begin with Step 2 under “Programming HomeLink®.”
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device
(most commonly, a garage door opener).
