2002 GMC SONOMA fog light

2-50 Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps or low
-beam headlamps
must be on for your fog lamps to work.
The fog lamp button is on the instrument panel near the
exterior lamps control.
Press the button to turn the fog lamps on. Press the
button again to turn them off. A light will glow in the
switch when the fog lamps are on.
The fog lamps will go off whenever your high
-beam
headlamps come on. When the high
-beam headlamps
go off, the fog lamps will come on again.
Interior Lamps
Instrument Panel Brightness Thumbwheel
This feature controls the brightness of the instrument
panel lights.
It is located on the driver's side of your instrument panel
next to the exterior lamps control.
Turn the thumbwheel up to make your instrument
panel lights brighter or down to dim them. Turn the
thumbwheel all the way up to turn on the interior lamps.
Illuminated Entry
Your vehicle is equipped with an illuminated
entry feature.
When any door is opened, the dome lamps will come on
if the DOME OVERRIDE button is in the out position.
If your vehicle is equipped with Remote Keyless Entry
and all the doors are closed, or the front door handles
are lifted and released, the lamps will stay on for a short
period of time and will turn off automatically. If you use
your keyless entry transmitter to unlock the vehicle, the
interior lights will come on for a short time whether or
not the DOME OVERRIDE button is in the out position.

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.
Storage Compartments
Glove Box
To open your glove box, lift the lever on the front of the
glove box and lower the door. The glove box should not be
open while driving.
Overhead Console (Crew Cab
)
(If Equipped)
The overhead console includes reading lamps, a
compartment for a garage door opener, a temperature
and compass display and a storage compartment
for sunglasses.

3-5 Air Conditioning (If Equipped)
On hot days, open the windows long enough to let hot
inside air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool
-down on very hot days, use MAX A/C
with the temperature knob turned counterclockwise.
This setting should be used to keep odors and/or dust
from entering the vehicle. For normal cooling on hot
days, use A/C with the temperature knob turned
counterclockwise.
On cool but sunny days, use bi
-level to deliver warm
air to the floor and cooler air to the instrument
panel outlets.
If you have the VORTEC 4300 V6 engine, when the air
conditioner is on, you may sometimes notice slight
changes in your vehicle's engine speed and power. This
is normal because the system is designed to cycle the
compressor on and off to keep the desired temperature.
Heating
The heater works best if you keep your windows closed
while using it. On cold days, use the floor outlets with
the temperature knob turned clockwise. Blend is useful
in cool weather when you have fog or ice on the
windshield or side windows.
If you use the optional engine coolant heater before
starting your engine, your heating system will produce
warmer air faster to heat the passenger compartment in
cold weather. See ªEngine Coolant Heaterº in the Index.
