REAR VIEW MIRROR BUICK LUCERNE 2008 User Guide

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to clear fog from
your windshield, defog and defrost.
W(Floor/Defog):Use this mode to clear the windows
of fog or moisture and to warm the passengers.
Turning the control to this mode directs about half of the
air to the oor outlets and the remaining air is directed
to the side window outlets and to the windshield.
When this mode is selected, the system turns off
recirculation and runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in
the oor/defog mode.
0(Defrost):Use this mode to remove fog or frost
from the windshield more quickly. Turning the control to
this mode directs most of the air to the windshield
and the side window outlets. In this mode, the system
automatically turns off recirculation and runs the
air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press this button to turn the rear
window defogger on or off. An indicator light below
the button comes on to show that the rear window
defogger is activated. Be sure to clear as much snow
from the rear window as possible.
The rear window defogger will only work when the
ignition is in ON/RUN. The rear window defogger stays
on for about 20 minutes after the button is pressed if
you are traveling at slower vehicle speeds. At higher
vehicle speeds the rear window defogger may stay on
continuously. If turned on again, the defogger only
runs for about 10 minutes before turning off. The
defogger can be turned off by pressing the button again,
by turning the ignition to ACC/ACCESSORY or
ON/RUN, or by turning off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when the
rear window defogger is on. SeeOutside Automatic
Dimming Heated Mirror on page 2-38for more
information.
Notice:Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere
anything to the defogger grid lines in the rear glass.
These actions may damage the rear defogger.
Repairs would not be covered by your warranty.

Customization Menu Items
U
(Customization):Press this button to enter the
feature settings menu. This display allows you to
customize the feature settings on your vehicle. SeeDIC
Vehicle Customization on page 3-66for more
information.
DIC Compass
Your vehicle may have a compass in the Driver
Information Center (DIC). The information below
explains how to operate this feature in the DIC.
If your vehicle has a compass in the mirror, see
Automatic Dimming Rearview Mirror with Compass on
page 2-36.
Compass Zone
Your dealer/retailer will set the correct zone for your
location.
Under certain circumstances, such as during a long
distance cross-country trip or moving to a new state or
province, it will be necessary to compensate for
compass variance by resetting the zone through the
DIC if the zone is not set correctly.
Compass variance is the difference between the earth’s
magnetic north and true geographic north. If the
compass is not set to the zone where you live, the
compass may give false readings. The compass must
be set to the variance zone in which the vehicle is
traveling.

Driving at Night
Night driving is more dangerous than day driving
because some drivers are likely to be impaired — by
alcohol or drugs, with night vision problems, or by
fatigue.
Night driving tips include:
Drive defensively.
Do not drink and drive.
Reduce headlamp glare by adjusting the inside
rearview mirror.
Slow down and keep more space between you and
other vehicles because your headlamps can only
light up so much road ahead.
Watch for animals.
When tired, pull off the road.
Do not wear sunglasses.
Avoid staring directly into approaching headlamps.
Keep the windshield and all glass on your vehicle
clean — inside and out.
Keep your eyes moving, especially during turns or
curves.
No one can see as well at night as in the daytime. But,
as we get older, these differences increase. A
50-year-old driver might need at least twice as much
light to see the same thing at night as a 20-year-old.

Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer/retailer before departing.
Things to check on your own include:
Windshield Washer Fluid:Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All levels checked?
Lamps:Do they all work and are lenses clean?
Tires:Are treads good? Are tires inated to
recommended pressure?
Weather and Maps:Safe to travel?
Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to your surroundings
while driving. If you become tired or sleepy, nd a
safe place to park your vehicle and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan the road ahead
and to the sides.
Check the rearview mirror and vehicle
instruments often.
