Section 2 Features and Controls
2-1
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 control 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 2-38for 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.
Automatic Dimming Rearview Mirror
with Compass
Your vehicle may have an automatic dimming rearview
mirror with a compass. It may also have OnStar®
controls. SeeOnStar®System on page 2-38for more
information.
When cleaning the mirror, use a paper towel or similar
material dampened with glass cleaner. Do not spray
glass cleaner directly on the mirror as that may cause
the liquid cleaner to enter the mirror housing.
2-33
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 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 3-23orDual Automatic Climate Control
System on page 3-26for 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. See
Turn and Lane-Change Signals on page 3-7for more
information.
2-37
Be sure to clear ice and snow from the wiper blades
before using them. If they are frozen to the windshield,
carefully loosen or thaw them. If your blades do
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 is equipped with wiper-activated
headlamps. After the windshield wipers have been on
for approximately six seconds, the headlamps will
automatically turn on. SeeWiper Activated Headlamps
on page 3-15for 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 will operate in the delay, low speed and
high speed modes. 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 delay position closest to
9(off) is the lowest sensitivity setting, level one.
The highest sensitivity setting, level ve, is closest to
6(low). A single wipe will occur each time you turn
the wiper control band 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
6(low) or1(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.

See “Rear Window Defogger” later in this section for
information on clearing the rear window of fog or ice.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and the side window outlets and half to the
oor outlets. When you select this mode, the system
turns recirculation off and runs the air conditioning
compressor unless the outside temperature is near or
below freezing. Pressing the recirculation button
will have no effect other than turning on the indicator
light while in defog mode.
0(Defrost):This mode directs most of the air to the
windshield and the side window outlets. When you select
this mode, the system turns recirculation off. Pressing the
recirculation button will have no effect other than turning
on the indicator light while in defrost mode.
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 will come on to let you know 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 run. The rear window defogger will stay on
for approximately 20 minutes after the button is
pressed if you are traveling at slower vehicle speeds.
At higher vehicle speeds, the rear defogger may stay on
continuously. If turned on again, the defogger will only
run for approximately 10 minutes before turning off.
The defogger can be turned off by pressing the button
again, by turning the ignition to B (ACCESSORY) or
C (RUN), or by turning off the engine.
If your vehicle has heated outside rearview mirrors,
the 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 2-37for 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.
3-25
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 approximately
half of the air to the oor outlets and the remaining air
is directed to the side window outlets and to the
windshield. When you select this mode, 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
will automatically turn off recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing. Recirculation cannot
be selected while in the defrost mode. Do not drive
the vehicle until all the windows are clear.
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 will come on to let you know 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 C (RUN). The rear window defogger will
stay on for approximately 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
will only run for approximately 10 minutes before turning
off. The defogger can be turned off by pressing the
button again, by turning the ignition to B (ACCESSORY)
or C (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 2-37for 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.

Driving at Night
Night driving is more dangerous than day driving.
One reason is that some drivers are likely to be
impaired — by alcohol or drugs, with night vision
problems, or
by fatigue.
Here are some tips on night driving.
Drive defensively.
Do not drink and drive.
Adjust the inside rearview mirror to reduce the glare
from headlamps behind you.
Since you cannot see as well, you may need to
slow down and keep more space between you
and other vehicles.
Slow down, especially on higher speed roads. Your
vehicle’s headlamps can light up only so much
road ahead.
In remote areas, watch for animals.
If you are tired, pull off the road in a safe place
and rest.
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 may require at least twice as much
light to see the same thing at night as a 20-year-old.What you do in the daytime can also affect your night
vision. For example, if you spend the day in bright
sunshine you are wise to wear sunglasses. Your eyes
will have less trouble adjusting to night. But if you
are driving, do not wear sunglasses at night. They may
cut down on glare from headlamps, but they also
make a lot of things invisible.
You can be temporarily blinded by approaching
headlamps. It can take a second or two, or even several
seconds, for your eyes to re-adjust to the dark. When
you are faced with severe glare, as from a driver
who does not lower the high beams, or a vehicle with
misaimed headlamps, slow down a little. Avoid
staring directly into the approaching headlamps.
Keep the windshield and all the glass on your vehicle
clean — inside and out. Glare at night is made much
worse by dirt on the glass. Even the inside of the glass
can build up a lm caused by dust. Dirty glass makes
lights dazzle and ash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that the headlamps light up far less of a
roadway when you are in a turn or curve. Keep
your eyes moving; that way, it is easier to pick out dimly
lighted objects. Just as the headlamps should be
checked regularly for proper aim, so should your eyes
be examined regularly. Some drivers suffer from
night blindness — the inability to see in dim light — and
are not even aware of it.
