air condition GMC SONOMA 2004 Owner's Manual

{CAUTION:
If something is between an occupant and an
air bag, the bag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating air bag must be kept clear. Don’t put
anything between an occupant and an air bag,
and don’t attach or put anything on the
steering wheel hub or on or near any other air
bag covering.
When Should an Air Bag Inate?
An air bag is designed to inflate in a moderate to severe
frontal, or near-frontal crash. The air bag will inflate
only if the impact speed is above the system’s designed
'threshold level'. If your vehicle goes straight into a
wall that doesn’t move or deform, the threshold level is
about 9 to 16 mph (14 to 26 km/h). The threshold
level can vary, however, with specific vehicle design, so
that it can be somewhat above or below this range. If
your vehicle strikes something that will move or deform,
such as a parked car, the threshold level will behigher. The air bag is not designed to inflate in rollovers,
rear impacts, or in many side impacts because inflation
would not help the occupant.
In any particular crash, no one can say whether an air
bag should have inflated simply because of the damage
to a vehicle or because of what the repair costs were.
Inflation is determined by the angle of the impact
and how quickly the vehicle slows down in frontal or
near-frontal impacts.
The air bag system is designed to work properly under
a wide range of conditions, including off-road usage.
Observe safe driving speeds, especially on rough
terrain. As always, wear your safety belt. SeeOff-Road
Driving with Your Four-Wheel-Drive Vehicle on
page 4-14for more tips on off-road driving.

Temperature and Compass Display
The outside air temperature and the compass are
displayed at the front of the overhead console. The
buttons are located to the left of the display.
ON/OFF:Press this button to turn the display on or off.US/MET:Press this button for the temperature to be
displayed in either degrees Farenheit (English) or
Celsius (metric).
Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on.
If the outside temperature is 37°F (3°C) or lower when
you turn on the ignition, the word ICE will appear
on the display. This is a warning to the driver that road
conditions may be icy, and that appropriate precautions
should be taken.
The compass is self-calibrating, so it does not need to
be manually set. However, when your vehicle is new, the
compass may function erratically. If it does, CAL
(Calibration) will appear on the display. To correct the
calibration, drive in a complete 360° circle three
times and the compass will function normally.

Driver Information Center (DIC)
If your vehicle is equipped with a Driver Information
Center (DIC), this system displays the outside air
temperature, compass direction and trip information in
the overhead console.
US/MET (United States/Metric):The US/MET (United
States/metric) button allows you to switch the display
between the English and metric system.
MODE:The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.
COMP/TEMP (Compass/Temperature):The display
provides the outside temperature and one of eight
compass readings to indicate the direction the vehicle is
facing.Before you turn on the ignition and move the vehicle,
the temperature indicated will be the last outside
temperature recorded with the ignition on. If the outside
temperature is 37°F (3°C) or lower, the display will
toggle between the ICE and the current temperature
every eight seconds. This is a warning to the drive that
road conditions may be icy, and that appropriate
precautions should be taken.
The compass is self-calibrating, so it does not need to
be manually set. However, if C (Calibration) is displayed,
the compass will need to be calibrated. You may also
place the compass in a noncalibrated mode by pressing
the holding the MODE and US/MET buttons at the
same time while in the COMP/TEMP mode. After about
10 seconds, the compass will display C and you can
release the buttons. Drive the vehicle in a complete
360° circle three times at a speed of less than 5 mph
(8 km/h), and the compass will function normally.
Once the calibration is complete, the display will return
to a compass reading.
2-38

A/C (Air Conditioning):Turn the knob to the A/C
position to turn the air-conditioning system on or
off. When the system is on, this setting cools and
dehumidifies the air entering your vehicle and directs it
through the floor outlets as well as the instrument
panel outlets.
MAX A/C (Maximum Air Conditioning):This mode
recirculates much of the air inside your vehicle so
it cools quickly. It directs most of the air through the
instrument panel outlets and a small amount through the
floor outlets.
For quick cool down on hot days, do the following:
1. Select A/C.
2. Select the coolest temperature.
3. Select the highest fan speed.
You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
The air-conditioning system removes moisture from the
air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling
or after turning off the engine. This is normal.Defogging and Defrosting
Fog on the inside of the 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 or frost from your windshield and side windows.
Use the defog mode to clear the windows of fog
or moisture and warm the passengers. Use the defrost
mode to remove fog or frost from the windshield
more quickly. For best results, clear all snow and ice
from the windshield before defrosting.
-(Defog):This mode can be used on cool, humid
days to keep the windshield and side windows clear.
1(Defrost):This mode directs most of the air to the
windshield and the side window outlets, with only a
little air directed to the floor outlets. When you select this
mode, the system runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
Do not drive the vehicle until all the windows are clear.
3-19

Outlet Adjustment
The flow through outlets on your vehicle allow outside
air to enter your vehicle while it is moving. Outside
air will also enter your vehicle while the air-conditioning
compressor is running.
Use the thumbwheels located in the center and on the
sides, to change the direction of the air flowing
through the outlets.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
•Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•Keep the path under the front seats clear of objects
to help circulate the air inside of your vehicle more
effectively.

Charging System Light
The charging system light
will come on briefly when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system. It could indicate
that you have problems with a generator drive belt, or
another electrical problem. Have it checked right
away. Driving while this light is on could drain your
battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and air conditioner.
Voltmeter Gage
When your engine is not
running, but the ignition is
on (in RUN), this gage
shows your battery’s state
of charge in DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading
in either warning zone. If you must drive, turn off
all unnecessary accessories.

This light should come on, as a check to show you it is
working, when the ignition is on and the engine is
not running. If the light does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
•Light Flashing— A misfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
•Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
•Reducing vehicle speed.
•Avoiding hard accelerations.
•Avoiding steep uphill grades.
•If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light Is On Steady” following.If the light continues to flash, when it is safe to do so,
stop the vehicle.Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart
the engine. If the light remains on steady, see “If
the Light Is On Steady” following. If the light is still
flashing, follow the previous steps, and see your dealer
for service as soon as possible.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. SeeFilling Your Tank on page 5-7. The
diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

Gasoline Specications
It is recommended that gasoline meet specifications
which were developed by automobile manufacturers
around the world and contained in the World-Wide
Fuel Charter which is available from the Alliance
of Automobile Manufacturers at www.autoalliance.org.
Gasoline meeting these specifications could provide
improved driveability and emission control system
performance compared to other gasoline.
In Canada, look for the
“Auto Makers’ Choice”
label on the pump.
California Fuel
If your vehicle is certified to meet California Emission
Standards (see the underhood emission control label),
it is designed to operate on fuels that meet California
specifications. If this fuel is not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp may
turn on (seeMalfunction Indicator Lamp on page 3-29)
and your vehicle may fail a smog-check test. If this
occurs, return to your authorized GM dealer for
diagnosis. If it is determined that the condition is caused
by the type of fuel used, repairs may not be covered
by your warranty.
