GMC SONOMA 2004 Owner's Manual

Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information
on accessory power outlets.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Check with your
dealer before adding electrical equipment.
When adding electrical equipment, be sure to follow the
proper installation instructions included with the
equipment.
Notice:Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.Ashtrays and Cigarette Lighter
Your vehicle may be equipped with an ashtray and
cigarette lighter.
Pull the front ashtray door down to open it.
Notice:If you put papers or other ammable items
in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put ammable items in the
ashtray.
To remove the front ashtray, pull the bin upward.
To use the lighter, press it in all the way, and let go.
When it’s ready, it will pop back out by itself.
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Operation
Mode Knob:Turn the right knob clockwise or
counterclockwise to direct the airflow inside of your
vehicle.
H(Vent):This mode directs air to the instrument
panel outlets, with a little air directed toward the
floor vents.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, then directs most of the
remaining air to the floor outlets. A little air is also
directed toward the windshield and the side window
outlets. Cooler air is directed to the upper outlets and
warmer air to the floor outlets.
6(Floor):This mode directs most of the air to the
floor outlets with a little air directed to the windshield and
the side window outlets.
9(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Turn the mode knob to OFF to turn off the fan.
The mode knob can also be used to select defog or
defrost mode. For more information, see “Defogging”
later in this section.
Temperature Knob:Turn the center knob clockwise or
counterclockwise to raise or lower the temperature
on the inside of your vehicle.
When it’s cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
seeEngine Coolant Heater on page 2-19.
3-18

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.

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Please follow this
manual’s advice. Waiting to do repairs can be
costly–and even dangerous. So please get to know your
warning lights and gages. They’re a big help.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, about how much fuel you’ve used, and many other things you’ll need to know to drive safely
and economically.
Base Level Cluster United States, Canada similar

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven, in either miles (used in the United States)
or kilometers (used in Canada).
The odometer mileage can be checked without the
vehicle running. Simply press the trip odometer button.
You may wonder what happens if your vehicle needs
a new odometer installed. If the new one can be set to
the mileage total of the old odometer, then it must
be. But if it can’t, then it’s set at zero, and a label must
be put on the driver’s door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
The trip odometer can tell you how far your vehicle
has been driven since you last set the trip odometer
to zero.
To view the trip odometer, press the button near the
readout. To reset the trip odometer, hold the button until
it resets.
Tachometer
The tachometer (if equipped) displays the engine speed
in revolutions per minute (rpm).
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind people to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will flash for
several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
3-24

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem.
The system check includes the air bag sensors, the air
bag modules, the wiring and the crash sensing and
diagnostic module. For more information on the air bag
system, seeAir Bag System on page 1-46.
This light will come on
when you start your
vehicle, and it will flash for
a few seconds. Then
the light should go out.
This means the system
is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed so it will
be ready to warn you if there is a problem.
3-25

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.
