Section 2 Features and Controls

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.

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.

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
®
Your vehicle may have an automatic dimming rearview
mirror with OnStar®system controls. For more
information about OnStar®, seeOnStar®System on
page 2-42.
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):Press the on/off button, located on the
lower left side of the mirror face, to turn the automatic
dimming feature on or off. 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.
2-37
Automatic Dimming Rearview Mirror
with OnStar
®and Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass display. The mirror also
contains OnStar
®controls. For more information see
OnStar®System on page 2-42.
The automatic dimming feature functions the same as
that of the automatic dimming rearview mirror without a
compass. SeeAutomatic Dimming Rearview Mirror
with OnStar
®on page 2-37.
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.
Mirror Operation
O
(On/Off):Press and hold the button, located on the
lower left side of the mirror face, for about three seconds
to turn the automatic dimming feature on or off.
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
untilaCisshown in the compass display.
2-38
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.
2-40
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.
2-41
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
GTurn and Lane-Change Signals. SeeTurn and
Lane-Change Signals on page 3-8
3Headlamp High/Low-Beam Changer. See
Headlamp High/Low-Beam Changer on page 3-9
Flash-To-Pass Feature
NWindshield Wipers. SeeWindshield Wipers on
page 3-9.
LWindshield Washer. SeeWindshield Washer
on page 3-11.
For more information on the exterior lamps, seeExterior
Lamps on page 3-15.
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 is 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 will not 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.
SeeRear Underseat Fuse Block on page 5-101.
