Section 2 Features and Controls
2-1
Sun Visors
Swing down the primary visor to block out glare. It can
also be detached from the center mount and moved
to the side while the auxiliary sunshade remains to block
the glare from the front. The visors also have
side-to-side slide capability.
The driver's sunshade is also equipped with a
storage ¯ap.
Lighted Visor Vanity Mirror
Pull the visor down and lift the cover to view the mirror.
The light will come on when the cover is opened. It
will go out when you close the cover. If your vehicle has
the adjustable lighting feature, slide the switch up or
down to brighten or dim the light.
Lighted Rear Vanity Mirror
Your vehicle may have lighted visor vanity mirrors for
the rear seat passengers. Pull the vanity cover down to
see the mirror. The light will come on when the cover
is opened. It will go out when you close the cover. If your
vehicle has the adjustable lighting feature, slide the
switch up or down to brighten or dim the light.
Rear Power Sunshade
If your vehicle is equipped with the rear power
sunshade, it helps to reduce the amount of heat and
light entering the rear window.
The rear power sunshade is located in the rear shelf.
The rear power sunshade switch only works while

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
ž
Your vehicle may have an automatic dimming rearview
mirror with OnStaržsystem controls. For more
information about OnStarž, seeOnStaržSystem on
page 2-45.
When the automatic dimming feature is turned on, the
mirror automatically changes to reduce glare from
headlamps behind you. A photocell on the mirror senses
when it is becoming dark outside. Another photocell
built into the mirror face senses when headlamps
are behind you.
At night, when the glare is too bright, the mirror will
gradually darken to reduce glare. This change may take
a few seconds. The mirror will return to its clear,
daytime state when the glare is reduced.
Mirror Operation
O
(On/Off):This is the on/off button, located on the
lower left side of the mirror face.
To turn the automatic dimming feature on or off, press
the on/off button. The indicator light will be illuminated
when the automatic dimming feature is on.
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.
Automatic Dimming Rearview Mirror
with OnStar
žand Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass display. The mirror also
contains OnStar
žcontrols. For more information seeOnStaržSystem on page 2-45.
The automatic dimming feature functions the same as
that of the automatic dimming rearview mirror without a
compass. See
Automatic Dimming Rearview Mirror
with OnStaržon page 2-40.
The mirror also includes an eight-point compass display
in the upper right corner of the mirror face. When on,
the compass automatically calibrates as the vehicle
is driven.
2-40
Mirror Operation
O
(On/Off):The on/off button is located on the lower
left side of the mirror face for the automatic dimming and
compass functions of the rearview mirror.
To turn on the automatic dimming feature, press and hold
the on/off button for about three seconds. To turn off
automatic dimming, press and hold the on/off button for
about three seconds again. The indicator light will
illuminate when this feature is active. The automatic
dimming feature is active each time the vehicle is started.
Compass Operation
Press the on/off button once to turn the compass on
or off.
When the ignition and the compass feature are on, the
compass will show two character boxes for about
two seconds. After two seconds, the mirror will display
the compass heading.
Compass Calibration
If after two seconds, the display does not show a
compass heading (for example, N for North), there may
be a strong magnetic ®eld interfering with the compass.
Such interference may be caused by a magnetic antenna
mount, magnetic note pad holder or a similar magnetic
item. If the letter C should ever appear in the compass
window, the compass may need calibration.The mirror can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display reads a
direction.
The compass can be placed in calibration mode
manually by pressing and holding the on/off button until
a C is shown in the compass display.
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.
2-41
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. See
Compass
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.
2-42
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. See
Turn 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 2-55andDIC Vehicle Personalization on page 3-67.
Outside Automatic Dimming Mirror
If your 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.
See
Automatic Dimming Rearview Mirror with OnStarž
on page 2-40.
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 cause the passenger's 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
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). See
DIC Vehicle
Personalization on page 3-67for more information.
2-43
Turn and Lane-Change Signals
To signal a turn, move the lever all the way up or down.
The lever returns automatically when the turn is
complete.
An arrow on the instrument
panel cluster and in the
outside rearview mirror will
¯ash in the direction of
the turn or lane change.
Raise or lower the lever until the arrow starts to ¯ash to
signal a lane change. Hold it there until the lane change is
complete. The lever returns when it's released.
If the turn signal is left on, a warning chime will sound and
the Driver Information Center (DIC) will display TURN
SIGNAL ON after driving about a mile to remind you to
turn it off.
Arrows that ¯ash rapidly when signaling for a turn or lane
change may be caused by a burned out signal bulb.
Other drivers won't see the turn signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse and for burned-out bulbs if the
arrow fails to work when signaling a turn. See
Fuses and
Circuit Breakers on page 5-94.
Headlamp High/Low-Beam Changer
Push forward to change the headlamps from low beam
to high. Pull the lever back and then release it to
change from high beam to low.
This light on the instrument
panel cluster will be on,
indicating high-beam
usage.
Flash-To-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
Pull and hold the turn signal lever toward you
to use. When you do, the following will occur:
·If the headlamps are either off or in the Daytime
Running Lamps (DRL) mode, the high-beam
headlamps will turn on. They'll stay on as long as
you hold the lever there. Release the lever to
turn them off.
·If the headlamps are on high beam, they will switch
to low beam. To return to high beam, push the
lever away from you.
