2008 BUICK LUCERNE rear view mirror

1(High Speed):For high-speed wiping, turn the
band further, to the second solid band past the
delay settings.
9(Off):To stop the wipers, move the band to off.
Clear ice and snow from the wiper blades before using
them. If they are frozen to the windshield, carefully
loosen or thaw them. If the blades become worn
or damaged, replace with new blades or blade inserts.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools. Clear
away snow or ice to prevent an overload.
Your vehicle has wiper-activated headlamps. After the
windshield wipers have completed eight wipe cycles
within four minutes, the headlamps automatically
turn on. SeeWiper Activated Headlamps on page 3-15
for 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 willoccur 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.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window 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 traveling at
slow speeds. At higher vehicle speeds, the rear 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.
If your vehicle has heated outside rearview mirrors, the
mirrors heat to help clear fog or frost from the surface of
the mirror when the rear window defogger is on. See
Outside Automatic Dimming Heated Mirror on page 2-38
for more information.
Notice:Do not use anything sharp on the inside of
the rear window. If you do, you could cut or
damage the warming grid, and the repairs would not
be covered by your warranty. Do not attach a
temporary vehicle license, tape, a decal or anything
similar to the defogger grid.
Dual Automatic Climate Control
System
The heating, cooling, and ventilation for the vehicle can
be controlled with this system.
If your vehicle has the remote start feature and it is
activated, the climate control system heats or cools the
inside of the vehicle, with the settings used before
the vehicle was turned off. The heated seats, if
the vehicle has them, and the rear window defogger will
be turned on by the climate control system when it is
cold outside. The cooled seat setting is not activated
during a remote start. Normal operation of the system
will return after the key is turned to the ON/RUN
position. SeeRemote Keyless Entry (RKE) System
Operation on page 2-5for more information.
3-24

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.
