2002 GMC SONOMA rear view mirror

2-51 Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition to help you see
while exiting the vehicle. These lights will stay on for a
short period of time and then will go out, if the DOME
OVERRIDE button is in the out position.
Front Map Lamps (If Equipped)
If your vehicle has front map lamps, they are located
on the inside rearview mirror. They will automatically
come on for approximately 40 seconds when the doors
are unlocked with the keyless entry transmitter (if
equipped) or until the ignition key is turned to RUN
or ACCESSORY. The lamps will also stay on for
approximately 40 seconds after you exit the vehicle,
unless you lock the doors with the keyless entry
transmitter.
You can also turn the lamps on and off by pressing the
switch near each lamp.
Dome Lamps
The dome lamps will come on when you open any door.
You can also turn the dome lamps on by turning the
thumbwheel, located next to the exterior lamps control,
all the way up to the second notch. In this position, the
dome lamps will remain on whether a door is opened or
closed.
You can use the DOME OVERRIDE button, located
below the exterior lamps control, to set the dome lamps
to come on automatically when any door is opened, or to
remain off. To turn the lamps off, press the button in.
With the button in, the dome lamps will remain off when
any door is opened. To return the lamps to automatic
operation, press the button again and return it to the out
position. With the button in this position, the dome
lamps will come on when you open any door. This will
override the illuminated entry feature, unless you use
your keyless entry transmitter (if equipped) to unlock
the vehicle.

2-52 Battery Rundown Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove box, cargo 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 rundown protection shuts off the interior
lamps, it may be necessary to do one of the following to
return it to normal operation:

Shut off all lamps and close all doors, or

turn the ignition key to RUN.
Mirrors
Inside Day/Night Rearview Mirror
Pull the tab under the mirror toward you to reduce glare
from headlamps behind you after dark. Push the tab
away from you for normal daytime operation.
Electrochromic Day/Night Inside Rearview
Mirror (If Equipped)
This mirror automatically changes to reduce glare from
headlamps behind you. A photocell on the back of the
mirror senses when it is becoming dark outside. Another
photocell built into the mirror surface senses when
headlamps are behind you.

2-54 Power Remote Control Rearview Mirrors
(If Equipped)
These controls are located
on the driver's door armrest.
Move the selector switch to the left or right to choose
the mirror, then use the arrows located on the four
-way
control pad to adjust the mirror.
Convex Outside Mirror
A convex mirror's surface is curved so you can see more
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 or left
lane, you could hit a vehicle. Check your inside
mirror or glance over your shoulder before
changing lanes.

2-55 Heated Outside Rearview Mirrors
(If Equipped)
Your vehicle may be
equipped with heated
outside rearview mirrors.
The heated mirror button is located to the lower right of
the mode knob on the climate control system. The
button has an indicator light to indicate if the heated
mirror feature is on or off.
When the heated mirror feature is turned on, the
defogger will warm the mirrors to help clear them of
snow or condensation. The heated mirror feature will
turn off automatically when the mirror is clear.

Here are some tips on night driving.

Drive defensively.

Don't drink and drive.

Adjust your inside rearview mirror to reduce the
glare from headlamps behind you.

Since you can't 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
headlamps can light up only so much road ahead.

In remote areas, watch for animals.

If you're 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're
driving, don't 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 readjust to the dark. When you
are faced with severe glare (as from a driver who
doesn't lower the high beams, or a vehicle with
misaimed headlamps), slow down a little. Avoid staring
directly into the approaching headlamps.
Keep your 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 film caused by dust. Dirty glass makes
lights dazzle and flash more than clean glass would,
making the pupils of your eyes contract repeatedly.
Remember that your headlamps light up far less of a
roadway when you are in a turn or curve. Keep your
eyes moving; that way, it's easier to pick out dimly
lighted objects. Just as your 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 aren't
even aware of it.
