Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove box and underhood lamps if they are left
on for more than 20 minutes when the ignition is off.
This will keep your battery from running down.
If the battery run
-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:

Shut off all lamps and close all doors, or

turn the ignition key to RUN.
This feature will also turn off the parking lamps and
headlamps under most circumstances, if they are left on.
If you would like to turn them back on, turn the exterior
lamps knob on.

are sitting in a comfortable driving position.

Automatic Dimming Feature
When turned on, an electrochromic mirror automatically
dims to the proper level to minimize glare from any
headlamps behind you after dark.
The automatic dimming feature is turned on and off by
pressing the far left button, located on the lower part of
the mirror face, for up to three seconds. A light on the
mirror will be lit when the feature is turned on. It will go
out when the feature is turned off.
Compass Operation
Press the on/off button once to turn the compass
on or off.

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. ªCALº will be
displayed in the compass window on the mirror.
The mirror can be calibrated in one of two ways:

Drive the vehicle in circles at 5 mph (8 km/h) or less
until the display shows ªCAL,º or

drive the vehicle on your everyday routine.
(This method may take longer to calibrate).
Compass Variance
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. 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 your current location and variance zone number
on the map.

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.
Heated Outside Rearview Mirrors
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. See ªRear Window Defoggerº in the
Index for more information.
Electrochromic Rearview Outside Mirror
with Curb View Assist (If Equipped)
If your vehicle has this feature, the driver's outside
mirror will adjust for the glare of the headlamps behind
you. See ªElectrochromic Day/Night Rearview Mirror
with Compass and OnStar

º earlier in this section.
If your vehicle is equipped with memory mirrors, it will
also be capable of performing the curb view assist
mirror function. This feature will cause the passenger's
and/or driver's mirror to tilt to a preselected 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
short delay has occurred, the passenger's and/or driver's
mirror will return to its original position.
To change the preselected tilt position, adjust the mirrors
to the desired position while the vehicle is in
REVERSE (R). When the vehicle is shifted out of
REVERSE (R), this new position is saved in memory as
the tilt position.
This feature can be enabled/disabled through the Driver
Information Center. See ªPersonalization Featuresº in
the Index for more information.
