The driver's and front passenger's window switches
have an express-down feature that allows you to lower
the window without holding the switch down. Press
down brie¯y on the bottom of the driver's window switch
labeled AUTO to activate the express-down feature.
Lightly tap the switch to open the window slightly. The
express-down feature can be interrupted at any time
by pressing the top of the switch.
Window Lockout
Your vehicle has a lockout feature to prevent
passengers from operating the power windows. The
lockout switch is located in front of the window switches.
A small light in the lockout switch will come on to
show that the switch has been activated. Press the
lockout switch again to return to normal operation.
Sun Visors
To block out glare, you can pull the visor down. You
can also slide the visor along the rod from side-to-side
to cover the driver or passenger front window.
Visor Vanity Mirror

Mirrors
Automatic Dimming Rearview Mirror
with OnStar
žand Compass
Your vehicle may have an automatic-dimming rearview
mirror with a compass and the OnStaržsystem.
There are three additional buttons for the OnStar
ž
system. See your dealer for more information on the
system and how to subscribe to OnStarž. SeeOnStarž
System on page 2-39for more information about the
services OnStaržprovides.
Mirror Operation
When turned on, this mirror automatically dims to the
proper level to minimize glare from any headlamps
behind you after dark.
O(On/Off): This is the on/off button for the automatic
dimming feature and compass. Press the far left button,
located below the the mirror face, for up to three
seconds to turn the feature on and off. A light on the
mirror will be lit while the feature is turned on.
Compass Operation
Press the on/off button once to turn the compass on or
off.
There is a compass display in the window in the upper
right corner of the mirror face. The compass displays
a maximum of two characters. For example, ªNEº
is displayed for north-east.
Compass Calibration
Press and hold the on/off button down for nine seconds
to activate the compass calibration mode. CAL will
be displayed in the compass window on the mirror.
The compass can be calibrated by driving the vehicle in
circles at 5 mph (8 km/h) or less until the display
reads a direction.
2-35

Compass Variance
Compass variance is the difference between earth's
magnetic north and true geographic north. The mirror 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, such as during a
long distance cross-country trip, it will be necessary to
adjust for compass variance. If not adjusted to
account for compass variance, your compass could give
false readings.
To adjust for compass variance, do the following:
1. Find your current location and variance zone
number on the map.
2. Press and hold the on/off button for six seconds.
Release the button when ZONE is displayed. The
number shown is the current zone number.
3. Scroll through the zone numbers that appear in the
compass/temperature window on the mirror by
pressing the on/off button. Once you ®nd your zone
number, release the button. After about four
seconds, the mirror will return to the compass
display, and the new zone number will be set.
2-36

Outside Manual Mirrors
Adjust your outside mirrors so you can see a little of the
side of your vehicle.
Fold the mirrors in before entering a car wash. To do
this, pull the mirrors in toward the vehicle. Push the
mirrors back out when ®nished.
Outside Power Mirrors
Your vehicle may have this feature.The control is located on the driver's door.
1. Twist the knob toward the mirror you desire to
adjust.
2. Move the knob in the direction you want the mirror
to go.
3. Adjust the mirror in all four directions.
4. After you are satis®ed with the position of the
mirror, twist the knob to the center position or twist it
to the other mirror to adjust that mirror.
If you reach the mirror's end of the travel position in any
direction, the mirror will enter a ratcheting mode. This
action is harmless. It is a warning that the mirror can go
no further. To stop this action, back the mirror up by
moving the knob in the opposite direction.
When the knob is twisted to the center position, the
mirrors can not be moved with the control knob.
2-37

Outside Convex Mirror
A convex mirror's surface is curved so you can see
more from the driver's seat.
{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 or left lane,
you could hit a vehicle. Check your inside
mirror or glance over your shoulder before
changing lanes.
Outside Heated Mirrors
Your vehicle may have this feature.
When you operate the rear window defogger, a defogger
also warms the heated driver's and passenger's
outside rearview mirrors to help clear them of ice, snow
and condensation.
Outside Automatic Dimming Mirror
with Curb View Assist
If your vehicle has this feature, the driver's and/or
passenger's outside mirror will adjust to a preset tilt
position while the vehicle is in REVERSE (R) gear. Curb
view assist may be useful when you are parallel
parking. The mirror(s) will return to normal position
when the vehicle is shifted out of REVERSE (R) gear.
Automatic mirror movement in either direction will follow
a short delay.
To change the tilt position, adjust the mirror while the
vehicle is in REVERSE (R) gear with the engine running,
the parking brake engaged and the brake pedal
pressed. The new position will be saved into memory
once the vehicle is shifted out of REVERSE (R).
You may be able to enable/disable this feature through
the Driver Information Center (DIC). See Mirror Curb
View Assist under
DIC Operation and Displays on
page 3-51.
2-38

Sunroof
Your vehicle may be equipped with a power sliding
sunroof. To open or close your sunroof, the ignition must
be on or Retained Accessory Power (RAP) must be
active.
Press and release the back of the button in the overhead
console to open the sunroof. Press the front of the
button to close the sunroof. Once the sunroof is closed,
press the forward side of the button to open the
sunroof to the vent position.
The sunroof is also equipped with a sunshade which
you can pull forward to block sun rays.
Vehicle Personalization
Memory Seat
Your vehicle may have this
feature. The controls are
located on the driver's
door, and are used
to program and recall
memory settings for the
driver's seating and
outside mirror positions.
Adjust the driver's seat (including the seatback recliner
and lumbar) and both of the outside mirrors to the
desired position. Then press and hold button 1
(for driver 1) for three seconds. A double chime will
sound to let you know that the position has been stored.
