2004 PONTIAC BONNEVILLE sensor

In many crashes severe enough to inate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.
Air bags are designed to inate only once. After an
air bag inates, you’ll need some new parts for
your air bag system. If you don’t get them, the air
bag system won’t be there to help protect you
in another crash. A new system will include air bag
modules and possibly other parts. The service
manual for your vehicle covers the need to replace
other parts.
Your vehicle is equipped with electronic frontal
sensors, which help the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module,
which records information about the frontal air bag
system. The module records information about
the readiness of the system, when the system
commands air bag ination and driver’s safety belt
usage at deployment. The module also records
speed, engine rpm, brake and throttle data.
Let only qualied technicians work on your air bag
systems. Improper service can mean that an air
bag system won’t work properly. See your dealer for
service.
Notice:If you damage the covering for the driver’s
or the right front passenger’s air bag, or the air
bag covering on the driver’s and right front
passenger’s seatback, the air bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right front
passenger’s air bag, or both the air bag module
and seatback for the driver’s and right front
passenger’s side impact air bag. Do not open or
break the air bag coverings.

;(Parking Lamps):Turn the switch to this position
to turn on the parking lamps, together with the
following:
Sidemarker Lamps
Taillamps
License Plate Lamps
Instrument Panel Lights
3(Headlamps):Turn the switch to this position to
turn on the headlamps, together with the previously
listed lamps and lights.
Wiper-Activated Headlamps
This feature turns on the low-beam headlamps,
instrument panel cluster backlighting and taillamps
when the Twilight Sentinel
®is in day mode and after
the windshield wipers have been in use for about
six seconds.
To operate the wiper-activated headlamps, the Twilight
Sentinel
®must be on. If the wiper-activated headlamps
are on and the ignition switch is turned to ON, the
wiper-activated headlamps will continue. When you turn
the key to OFF, the wiper-activated headlamps will
immediately turn off. The wiper-activated headlamps will
also turn off if you turn off the Twilight Sentinel
®or
the windshield wipers.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
daytime running lamps are required on all vehicles
rst sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL and
Twilight Sentinel
®, so be sure it is not covered. The DRL
system will make your high-beam headlamps come
on at a reduced brightness when the following conditions
are met:
The ignition is on.
The exterior lamp control is off.
The transaxle is not in PARK (P).
When the DRL are on, only your high-beam headlamps
will be on at reduced intensity. The taillamps,
sidemarker and other lamps will not be on. Your
instrument panel will not be lit either.

Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed.
1. Press the AUTO button. Whenever this button is
pressed, the display will show the current settings
for ve seconds before returning the display to
the exterior temperature.
2. Adjust the temperature to 75°F (24°C).
Choosing the coldest or warmest temperature
setting will not cause the system to cool or heat any
faster. If you set the system at the coldest or
warmest temperature setting, the system will remain
at the maximum cold or hot setting and fan speed.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see “Sensors” later in
this section.
Manual Operation
DRIVER (Driver’s Side Temperature):The knob on
the left is used to change the temperature of the
air coming through the system on the driver’s side of
the vehicle. Push this knob to turn the system on and off.
Turn the knob toward the blue area to decrease the
set temperature, and toward the red area to increase the
set temperature. When this knob is adjusted, the word
DRIVER will be displayed under the set temperature.
When the passenger’s set temperature is not active, this
knob controls both the driver’s and passenger’s side,
and both DRIVER and PASS will be displayed under the
set temperature.

?RECIRC (Recirculation):Press this button to
limit the amount of outside air coming into the vehicle. It
can be used to prevent outside air and odors from
entering your vehicle or to help heat or cool the
air inside your vehicle more quickly. Press this button to
turn the recirculation mode on or off. When the button
is pressed, an indicator light will come on. The
recirculation mode cannot be used with the FRONT
defrost mode.
#A/C (Air Conditioning):Press this button to
override the automatic system and turn the air
conditioning system on or off. When A/C is pressed, an
indicator light in the button will come on to let you
know that it is activated. When in AUTO, the air
conditioning compressor will come on automatically, as
necessary. The air conditioning compressor will also
run when you select the FRONT defrost mode and
outside temperatures are above freezing.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, press the AUTO
button and the system will automatically enter
recirculation mode and the temperature will be at the full
cold position for maximum cooling.Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
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.Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments to the temperature, the fan
speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing the
sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located in the
center of the instrument panel, near the windshield,
or the system will not work properly.
There is also an EXT (exterior) temperature sensor
located behind the front grill. This sensor reads
the outside air temperature and helps to maintain the
temperature inside the vehicle. Any cover on the front of
the vehicle could cause a false reading in the
temperature.

Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. 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 Systems on page 1-51.
This light will come on
when you start your
vehicle, and it will ash 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 ash for a few
seconds when you turn the ignition key to ON. If the
light doesn’t come on then, have it xed so it will
be ready to warn you if there is a problem.
On vehicles with the DIC, a SERVICE AIR BAG
message will be displayed when there is a problem with
the air bag system. SeeDIC Warnings and Messages
on page 3-61for more information.
