Section 2 Features and Controls
2-1

Personalization Features
If your vehicle has the
Driver Information Center
(DIC), the numbers on the
back of the transmitters
correspond to the DIC’s
Driver #1 and Driver #2.
SeeDriver Information
Center (DIC) on page 3-59,
for more information.
The following features, if available on your vehicle, can
be programmed to each driver’s preference.
Programmable Automatic Door Locks
Security Feedback
Delayed Locking
Perimeter Lighting
Seat and Mirror Recall
If your vehicle is equipped with the Driver Information
Center (DIC), you must program these features through
the DIC. SeeDIC Vehicle Personalization on page 3-64.
Security Feedback
This feature provides feedback to the driver when the
vehicle receives a command from the remote keyless
entry transmitter. Feedback is only provided if all doors
are closed, the ignition is off and the Retained
Accessory Power (RAP) is inactive.
If your vehicle is equipped with the Driver Information
Center (DIC), you must program this feature through the
DIC. SeeDIC Vehicle Personalization on page 3-64.

Mode 1:No feedback when locking or unlocking
vehicle.
Mode 2:Parking lamps and the daytime running lamps
will ash twice when unlocking the vehicle and will
ash once when locking the vehicle.

(second unlock button press) and when locking
the vehicle.
Mode 4:Parking lamps and the daytime running lamps

Sun Visors
To block out glare, you can swing down the visors.
You can also remove them from the center mount and
swing them to the side.
Visor Vanity Mirror
Open the cover to expose the vanity mirror.
If your vehicle has the optional lighted vanity mirrors,
the lamps come on when you open the cover.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Universal Theft-Deterrent
If your vehicle has this feature, it has a theft-deterrent
alarm system. With this system, the SECURITY light will
ash as you open the door if your ignition is in OFF.
This light on the instrument panel cluster reminds you
to activate the theft-deterrent system when leaving
your vehicle.
To activate the system, do the following:
1. Open the door.
2. Lock the door with the power door lock switch while
the door is open, or use the remote keyless entry
transmitter, if equipped. The SECURITY light should
come on and stay on.
3. Close all doors. The SECURITY light should go off
after about 30 seconds and the system will then
be armed. United States and V6

Mirrors
Manual Rearview Mirror
While sitting in a comfortable driving position, adjust the
mirror so you can see clearly behind your vehicle. Grip
the mirror in the center to move it up or down and side to
side. The control at the bottom of the mirror is the
day/night feature that allows adjustment to the mirror so
that the glare of headlamps from behind is reduced. Push
the tab for daytime use; pull it for night use.
Automatic Dimming Rearview Mirror
The vehicle may have an automatic dimming rearview
mirror. It may also have OnStar®controls. SeeOnStar®
System on page 2-39for more information.
At night, when glare from lights is high, the mirror will
gradually darken. This change may take a few seconds.
The mirror will return to its clear daytime state when
glare is reduced.
Mirror Operation
AUTO:Press this button to turn on the automatic
dimming feature.
OFF:Press this button to turn off the automatic
dimming feature.
O(On/Off):For mirrors equipped with OnStar®
controls, press this button to turn the automatic dimming
feature on or off.
The indicator light will be illuminated when this feature
is on.
2-36

Outside Power Mirrors
The controls for the outside power mirrors are located
on the driver’s door armrest.
Press the left or right side of the L/R selector switch
located beneath the control pad to choose the left
or right mirror.To adjust the mirror, use one of the four arrows located
on the control pad to move the mirror in the direction
you want it to go. When nished adjusting the mirrors,
leave the L/R selector switch in the center position,
to prevent unwanted mirror movement in case the
control pad is accidentally bumped while driving. Adjust
each outside mirror so that you can see a little of
your vehicle and the area behind your vehicle.
If your vehicle is equipped with the memory function,
the mirrors and driver’s seat position can be stored into
memory. SeeMemory Seat and Mirrors on page 2-46.
2-37

Outside Curb View Assist Mirror
If you have the memory seat and mirrors feature, the
passenger’s outside power mirror also includes a
tilt-down feature that operates when the shift lever is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), the passenger’s mirror will return to its
original position after a ve-second delay. This delay
prevents movement of the mirror if multiple gear
transitions (REVERSE (R) to AUTOMATIC
OVERDRIVE (D) to REVERSE (R)) occur during a
parallel parking maneuver. This feature can be
programmed on or off through the DIC personalization
programming menu. SeeDIC Vehicle Personalization on
page 3-64for programming instructions.
Outside Convex Mirror
The passenger’s side mirror is convex. A convex
mirror’s surface is curved so more can be seen 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 lane, you
could hit a vehicle on your right. Check your
inside mirror or glance over your shoulder
before changing lanes.
Outside Heated Mirrors
If your vehicle has this feature, when you operate the
rear window defogger, the heated driver’s and
passenger’s outside power mirrors are warmed to help
clear them of ice and snow. See “Rear Window
Defogger” underClimate Control System on page 3-25
orAutomatic Climate Control System on page 3-28
for more information.

Comfort Stop:Press and release the switch rearward
to the second position to express open the glass
panel to the comfort stop position. The comfort stop
position is designed to help reduce noise and make
passengers more comfortable.
Express Open:When the glass panel is express
opening, pressing the switch in any direction will stop it
in a partially-opened position. The glass panel may
be fully opened by pressing the switch rearward again.
If you press and hold the switch in the express open
position for more than one and a half seconds, the
express open operation will be overridden and
the sunroof will operate manually.
Close:To close the glass panel, press and hold the
switch forward. As the glass panel reaches the closed
position, it will open slightly toward the vent position and
then drop down to the closed position to provide a
better seal. The sunshade must be closed manually.
Vent:Once the sunroof is closed, it can be opened to
the vent position by pushing the switch upward. To
close the glass panel, pull the switch downward. The
sunshade must be opened and closed manually for vent
operation.Vehicle Personalization
Memory Seat and Mirrors
If your vehicle has this
feature, the controls are
located on the driver’s door
panel, and are used to
program and recall
memory settings for the
driver’s seating, outside
mirror positions and
climate controls. SeeDIC
Vehicle Personalization
on page 3-64for more
information.
To save your seat and mirror positions into memory, do
the following:
1. First identify the DRIVER # on the Driver Information
Center (DIC) by pressing memory button 1 or 2 or
by pressing the unlock button on the remote keyless
entry transmitter. SeeDriver Information Center
