2007 BUICK LUCERNE mirror

Automatic Dimming Rearview Mirror
with Compass
Your vehicle may have an automatic dimming
rearview mirror with a compass. This feature
enables the mirror to sense nighttime glare from
vehicle headlamps from behind and automatically
dim to reduce the glare to a safe level. The
automatic dimming feature turns on each time the
vehicle is started.
O(On/Off):This is the on/off button.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned on
automatically each time the ignition is started. To
operate the automatic dimming mirror, do the
following:
1. Make sure the indicator light, located to the left
of the on/off button, is on. If it’s not, press and
hold the on/off button until the light comes on,
indicating that the mirror is in automatic
dimming mode.
2. Turn off the automatic dimming mirror function
by pressing and holding the on/off button until
the indicator light turns off.
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
a few seconds. After a few seconds, the mirror
will display the current compass direction.
Compass Calibration
If after a few seconds the display does not show a
compass direction, (N for North for example), there
may be a strong magnetic eld interfering with the
compass. Such interference may be caused by a
magnetic antenna mount, note pad holder, or
similar object. If the letter C or CAL appears in the
compass window, the compass may need to be
reset or calibrated.
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.

Compass Variance
Compass variance is the difference between earth’s
magnetic north and true geographic north. If the
mirror is not adjusted for compass variance, the
compass could give false readings.
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if the
vehicle is driven outside zone eight. Under
certain circumstances, such as a long distance,
cross-country trip, it will be necessary to adjust the
compass variance.
To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the zone map. SeeAutomatic
Dimming Rearview Mirror with OnStar
®and
Compass on page 130for map information.
2. Press and hold the on/off button until a zone
number appears on the display.
3. Once the zone number appears on the display,
press the on/off button quickly until you reach
the correct zone number. If C or CAL appears
in the compass window, the compass may
need calibration. See “Compass Calibration”
listed previously.
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 selector switch
located beneath the control pad to choose the left
or right mirror.
To adjust the mirror, press one of the four arrows
located on the control pad to move the mirror
in the direction you want it to go. Adjust each
outside mirror so that you can see a little of your
vehicle, and the area behind your vehicle.
The mirrors may also have an arrow that ashes
when the turn signal is used. SeeTurn and
Lane-Change Signals on page 162.

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
driver’s and 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)
or the ignition is turned to off, the driver’s and
passenger’s side mirror will return to its original
position.
SeeDIC Vehicle Customization on page 231for
more information.
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.
134

Outside Automatic Dimming
Heated Mirror
If you have this feature, the outside driver’s mirror
will adjust for the glare of headlamps behind you.
When you operate the rear window defogger, the
heated driver’s and passenger’s outside rearview
mirrors are warmed to help clear them of ice and
snow. See “Rear Window Defogger” underClimate
Control System on page 182orDual Automatic
Climate Control System on page 186for more
information.
Your vehicle may also have a turn signal indicator
on the mirror. An arrow on the outside rearview
mirror will ash in the direction of the turn or lane
change. SeeTurn and Lane-Change Signals
on page 162for more information.

Rainsense™ II Wipers
If your vehicle has this feature, the moisture sensor
is mounted on the interior of the windshield beside
the rearview mirror and is used to automatically
operate the wipers. This system operates by
monitoring the amount of moisture build-up on the
windshield. Wipes occur as needed to clear the
windshield depending on the driving conditions and
the sensitivity setting. In light rain or snow, fewer
wipes will occur. In heavy rain or snow, wipes will
occur more frequently. The system operates in the
delay mode. If the system is left on for long periods
of time, occasional wipes may occur without any
moisture on the windshield. This is normal and
indicates that the Rainsense™ system is active.
The Rainsense™ system is activated by turning
the wiper control band to one of the ve sensitivity
levels within the delay area. The position closest
to off is the lowest sensitivity setting, level one.This allows more rain or snow to collect on the
windshield between wipes. Turning the wiper band
away from you to higher sensitivity levels increases
the sensitivity of the system and frequency of
wipes. The highest sensitivity setting, level ve is
closest to low. A single wipe will occur each time
you turn the wiper stalk to a higher sensitivity level
to indicate that the sensitivity level has been
increased.
Notice:Going through an automatic car wash
with the wipers on can damage them. Turn the
wipers off when going through an automatic
car wash.
The MIST and wash cycles operate as normal and
are not affected by the Rainsense™ function. The
system can be overridden at any time by manually
changing the wiper control to low or high speed.
Notice:Do not place stickers or other items
on the exterior glass surface directly in front of
the rain sensor. Doing this could cause the
rain sensor to malfunction.
