sensor Oldsmobile Bravada 2003 Owner's Manuals

In many crashes severe enough to inflate 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 inflate only once. After an
air bag inflates, 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 an electronic frontal
sensor, which helps 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 inflation and driver’s safety belt
usage at deployment. The module also records
speed, engine
RPM, brake and throttle data.
Let only qualified 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 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.

Windshield Wipers
(Mist): For a single wiping cycle, turn the band to
mist. Hold it there until the wipers start. Then let go.
The wipers will stop after one wipe. If you want
more wipes, hold the band on mist longer.
0 (Off): To stop the wipers, move the band to off.
(Windshield Wipers): Turn the band to control i
windshield wipers. :he
You can set the wiper speed for a long or short delay
between wipes. This can be very useful in light rain
or snow. Turn the band
to choose the delay time. The
closer
to the top of the lever, the shorter the delay.
For steady wiping at low speed, turn the band away from
you
to the first solid band past the delay settings. For
high-speed wiping, turn the band further,
to the second
solid band past the delay settings. To stop the wipers,
move the band
to off.
Be sure to clear ice and snow from the wiper blades
before using them. If they’re frozen
to the windshield,
carefully loosen or thaw them. If your blades do become
worn or damaged, get new blades or blade inserts.
RainsenseTM Wipers
Your vehicle may be equipped with
RainsenseTM windshield wipers. When active, these
wipers are able
to detect moisture on the windshield and
automatically turn on the wipers.
The moisture sensor is located next to the inside
rearview mirror and is mounted on the windshield.
To turn on the RainsenseTM feature, the wipers must be set
to one of the five delay settings on the multifunction
lever. Each of the five settings adjusts the sensitivity
of the rainsensor. For more wipes, select the higher
settings; for fewer wipes, select the lower settings
located closer
to off on the multifunction lever.
The rainsensor will automatically control the frequency
of the wipes from
off to high speed according to the
weather conditions. The wipers can be left in a
rainsense mode even when it
is not raining.
Notice: Turn the windshield wiper band on the
multifunction lever
to off to avoid wiper damage
when going through an automatic car wash.

Automatic Headlamp System
When it is dark enough outside, your automatic
headlamp system will turn on your headlamps at the
normal brightness along with other lamps such as
the taillamps, sidemarker, parking lamps and the
instrument panel lights. The radio lights will also be on.
Your vehicle is equipped with a light sensor on the
top of the instrument panel. Be sure it is not covered or
the system will be on whenever the ignition is on.
The system may also turn on your lights when driving
through a parking garage, heavy overcast weather
or a tunnel. This is normal.
There is a delay in the transition between the daytime
and nighttime operation
of the Daytime Running
Lamps (DRL) and the automatic headlamp systems,
so
that driving under bridges or bright overhead street
lights does not affect the system. The DRL and
automatic headlamp system will only be affected when
the light sensor sees a change in lighting lasting
longer than the delay. If
you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
one minute for the automatic headlamp system to
change to DRL
if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position.
To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is off.
Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake,
shift out
of park or turn the exterior lamp control to
the
off position as described in “Exterior Lamps”.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver’s door
is open and your ignition is in LOCK or ACCESSORY.
To turn the tone off, turn the knob all the way
counterclockwise. In the automatic mode, the headlamps
turn
off once the ignition key is in LOCK.

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
first sold in Canada.
The DRL system will make your headlamps come on
at
reduced brightness when the following conditions
are met:
The ignition is on,
the exterior lamps knob is in automatic
the light sensor detects daytime light, and
the transmission is not in PARK (P).
headlamp
mode,
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won’t be
on. The instrument panel won’t be lit up either.
When it begins
to get dark, the headlamps will
automatically switch from DRL
to the regular headlamps.
Fog Lamps
Your vehicle may have this feature. Use your fog lamps
for better vision in foggy or misty conditions. Your
ignition must be in RUN for your fog lamps
to work.
The fog lamp button is
located on the instrument
panel
to the right of
the exterior lamps knob.
Press the button
to turn thl
fog lamps on. Press the e
button again to turn them off. A light will glow near the
button when the fog lamps are on. Fog lamps will
turn off whenever your high-beam headlamps are on.

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.
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 baa
system, see
Air Bag Systems 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.
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 inflate in a crash, or they
could even inflate 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.

Don’t leave an unsecured child resL,int in
your vehicle.
When you carry something inside the
vehicle, secure it whenever you
can.
Don’t leave a seat folded down unless you
need to.
There’s also important loading information for off-road
driving in this manual.
Electronically Controlled Air
Suspension System
Your vehicle may be equipped with an electronically
controlled air suspension system that automatically
keeps your vehicle level as you load and unload. The
system includes a compressor, two height sensors
and two air springs supporting the rear axle. The system also has an internal clock to prevent
overheating.
If the system overheats, all leveling function
stops until the system cools down. During this time, the
indicator light on the air inflator system will be flashing.
The ignition has
to be on for the system to inflate, in
order
to raise the vehicle to the standard ride height after
loading. The system can lower the vehicle
to the
standard ride height after unloading with the ignition on
and also for up
to 30 minutes after the ignition has
been turned
off.
You may hear the compressor operating when you load
your vehicle, and periodically as the system adjusts
the vehicle
to the standard ride height.
Load leveling will not function normally with the inflator
hose attached
to the inflator outlet. Remove the
inflator hose from the outlet during loading and
unloading.
If the vehicle is parked for an extended period of time,
some bleed down of the suspension is normal. Upon
starting the vehicle, proper height will be achieved.
