2003 Oldsmobile Bravada air condition

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.
For frontal air bags, inflation is determined by the angle
of the impact and how quickly the vehicle slows down
in frontal and near-frontal impacts. For side impact
air bags, inflation is determined by the location and severity of the impact.
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. See
Operating
Your All-Wheel-Drive Vehicle
Off Paved Roads on
page
4-15 for tips on off-road driving.
What Makes an Air Bag Inflate?
In an impact of sufficient severity, the air bag sensing
system detects that the vehicle is in a crash. For
both frontal and side impact air bags, the sensing
system triggers a release of gas from the inflator, which
inflates the air bag. The inflator, the air bag and
related hardware are all part of the air bag modules.
Frontal air bag modules are located inside the steering
wheel and instrument panel. For vehicles with side
impact air bags, the air bag modules are located in the
seatback closest
to the driver’s and/or right front
passenger’s door.
How Does an Air Bag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel or
the instrument panel. In moderate
to severe side
collisions, even belted occupants can contact the inside
of the vehicle. The air bag supplements the protection
provided by safety belts. Air bags distribute the force of
the impact more evenly over the occupant’s upper
body, stopping the occupant more gradually. But the
frontal air bags would not help you in many types
of collisions, including rollovers, rear impacts, and many
side impacts, primarily because an occupant’s motion
is not toward the air bag. Side impact air bags would not
help you in many types of collisions, including frontal
or near frontal collisions, rollovers, and rear impacts,
primarily because an occupant’s motion is not toward
those air bags. Air bags should never be regarded
as anything more than a supplement
to safety belts, and
then only in moderate
to severe frontal or near-frontal
collisions for the driver’s and right front passenger’s
frontal air bags, and only in moderate
to severe
side collisions for vehicles with a driver’s and right front
passenger’s side impact air bag.

This vehicle has one double-sided key for the
ignition and door locks. It
will fit with either side up.
When a new vehicle is delivered, the dealer provides
the owner with a pair of identical keys and a key
code number.
The key code number tells your dealer or a qualified
locksmith how to make extra keys. Keep this number in
a safe place. If you lose your keys, you’ll be able to
have new ones made easily using this number.
Your selling dealer should also have this number. Notice: Your vehicle has a number of features that
can help prevent theft. You can have a lot of trouble
getting into your vehicle if you ever lock your keys
inside. You may even have to damage your vehicle
to
get in. So be sure you have spare keys.
If you ever do get locked out of your vehicle, call the
GM Roadside Assistance Center. See Roadside
Assistance Program
on page 7-5.
If your vehicle is equipped with the Onstar@ system
with an active subscription and you lock your keys inside

Automatic Operation Manual Operation
AUTO
(Automatic): When automatic operation is
active, the system will control the inside temperature,
the air delivery mode, and the fan speed.
Use the steps below to place the entire system in
automatic mode:
1. Press the AUTO button.
When AUTO is selected, the air conditioning
operation and air inlet will be automatically
controlled. The air conditioning compressor will run
when the outside temperature is over approximately
40°F (4°C). The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet will
automatically switch to recirculate inside air to help
quickly cool down your vehicle.
2. Set the driver’s and passenger’s temperature.
To find your comfort setting, start with a 72°F (22°C)
temperature setting and allow about 20 minutes
for the system to regulate. Turn the driver’s or
passenger’s side temperature knob to adjust the
temperature setting as necessary. If you choose the
temperature setting
of 60°F (15”C), the system
will remain at the maximum cooling setting.
If you
choose the temperature setting of 90°F
(32”C),
the system will remain at the maximum heat setting.
Choosing either maximum setting may not cause
the vehicle to heat or cool any faster. To change
the current setting, select one of the
following:
v (Fan): This button allows you to manually
adjust the fan speed. Press the up arrow to increase fan
speed and the down arrow to decrease fan speed.
The display will change to show you the selected fan
speed and the driver’s side temperature setting for five
seconds.
@* *d (Mode): Press this button to manually change the
direction of the airflow in your vehicle. Keep pressing the
button until the desired mode appears on the display.
The display will change to show you the selected
air delivery mode and the driver’s temperature setting
for five seconds.
2 (Vent): This mode directs air to the instrument
panel outlets.
+2 (Bi-Level): This mode directs approximately half of
the air to the instrument panel outlets, then directs
the remaining air to the floor outlets. A little air is
directed toward the windshield and the side window
outlets. Cooler air is directed to the upper outlets and
warmer air to the floor outlets.
3-22

4; (Floor): This mode directs most of the air to the
floor outlets. Some air also comes out of the defroster
and side window outlets. The recirculation button cannot
be selected in floor mode.
&I (Recirculation): Press this button to turn
recirculation mode on or
off. When this button is
pressed, an indicator light in the button will also come
on
to let you know that it is activated. Recirculation
mode is used
to recirculate the air inside of your vehicle.
Use this mode to help prevent outside odors and/or
dust from entering your vehicle or to help cool the air
inside of your vehicle more quickly. Recirculation
mode can be used with vent and bi-level modes, but it
cannot be used with floor, defog or defrost modes.
If the weather
is cold and damp, the system may cause
the windows to fog while using recirculation mode. If the
windows do start to fog, select defog or defrost mode.
)#t A/C (Air Conditioning): Press this button to
manually turn the air conditioning system on or
off.
When the system is on, the system will automatically
begin to cool and dehumidify the air inside of your
vehicle.
If you select air conditioning off while in front defrost or
defog mode, the air conditioning
off symbol will flash
to let you know this is not allowed. You
may notice a slight change in engine performance
when the air-conditioning compressor shuts
off and
turns on again. This is normal.
(Air Conditioning Off): When you turn the air
conditioning
off, this symbol will appear on the display.
When the air conditioning is selected or in AUTO mode,
the system will run the air conditioning automatically.
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. You can use either defog or front defrost
to clear fog or frost from your windshield.
+3 (Defog): Use this setting to clear the windows of fog
or moisture. This setting will deliver air
to the floor
and windshield outlets.
@ (Front Defrost): Press the front defrost button to
defrost the windshield. The system will automatically
control the fan speed
if you select defrost from AUTO
mode. If the outside temperature is
40°F (4°C) or
warmer, your air conditioning compressor will
automatically run to help dehumidify the air and dry the
windshield.
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 from the rear window.
Press this button
to turn
the rear window defogger
on or
off
An indicator light in the button will come on to let you
know that the rear window defogger is activated.
The rear window defogger will turn
off approximately 10
minutes after the button is pressed. If you need
additional warming time, press the button again.
Notice: Don’t use a razor blade or something else
sharp on the inside
of the rear window. If you
do, you could cut or damage the defogger and the
repairs would not be covered by your warranty.

decal or anything similar to the defogger grid.
Do not attach a temporary vehicle license, tape, a decal
or anything similar
to the defogger grid.
Outlet Adjustment
Use the air outlets located in the center and on the side
of your instrument panel
to direct the airflow.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use the vent setting
to direct outside
air through your vehicle.
Your vehicle’s ventilation system supplies outside air
to
the inside of your vehicle when it is moving. With the
side windows closed, air will flow into the front air inlet
grilles, through the vehicle and out the air exhaust
valves.
Outside air will also enter the vehicle when the heater
or the air conditioning compressor is running, unless you
have the recirculation button pushed in.

Operation Tips
e
e
e
Keep the hood and front air inlets free of ice, snow,
or any other obstruction (such
as leaves). The
heater and defroster will work far better, reducing
the chance of fogging the inside of your windows.
When you enter a vehicle in cold weather, turn the
fan knob all the way
to the right for a few moments
before driving. This helps clear the intake ducts
of snow and moisture, and reduces the chance of
fogging the inside of your window.
Keep the air path under the front seats clear of
objects. This helps air
to circulate throughout
your vehicle.
Adding outside equipment
to the front of your
vehicle, such as hood-air deflectors, may affect the
performance of the heating and air conditioning
system. Check with your dealer before adding
equipment
to the outside of your vehicle.
Rear Climate Control System
The lower buttons on the rear seat audio are used to
adjust the rear seat comfort controls. The temperature of
the air coming through the rear outlets is determined
by the front passenger’s temperature setting. The button
with the up and down arrows on
it regulates the fan
speed. The mode button is used
to change the direction
of airflow (upper, bi-level or floor) to the rear seat
area. To turn the rear comfort controls off, press the
lower
PWR button.

The
charging system light
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
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. a
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.

This system is called OBD II (On-Board
Diagnostics-Second Generation) and is intended
to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. The SERVICE ENGINE SOON or CHECK
ENGINE light comes on and a chime will sound
to
indicate that there is a problem and service is required. Malfunctions often will be indicated by the system
before any problem is apparent. This may prevent more
serious damage
to your vehicle. This system is also
designed to assist your service technician in correctly
diagnosing any malfunction.
Notice: If you keep driving your vehicle with this
light on, after a while, your emission controls
may not work as well, your fuel economy may not
be as good and your engine may not run as
smoothly. This could lead to costly repairs that may not be covered by your warranty.
Notice: Modifications made to the engine,
transmission, exhaust, intake or fuel system of your
vehicle or the replacement of the original tires
with other than those of the same Tire Performance Criteria (TPC) can affect your vehicle’s emission
controls and may cause this light to come on.
Modifications to these systems could lead to costly
repairs
not covered by your warranty. This may
also result in a failure to pass a required Emission
Inspection/Maintenance test.

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 doesn’t come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
0 Light Flashing - A misfire condition has been
detected. A misfire increases vehicle emissions
and may damage the emission control system on
your vehicle. Dealer or qualified service center
diagnosis and service may be required.
Light On Steady - An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center 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.
