sensor OLDSMOBILE BRAVADA 1998 Owners Manual

0 Air bags are designed to inflate only once. After they
inflate, 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.
0 Your vehicle is equipped with a diagnostic module,
which records information about the air bag system.
The module records information about the readiness
of the system, when the sensors
are activated and
driver’s safety belt usage at deployment.
0 Let only qualified technicians work on your air bag
system. Improper service can mean that your air bag
system won’t work properly. See your retailer for service.
NOTICE:
If you damage the covering for the driver’s or the
right front passenger’s air bag, the bag may not
work properly. You may have to replace the air
bag module in the steering wheel or both the
air
bag module and the instrument panel for the
right front passenger’s air bag.
Do not open or
break the air bag coverings.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle.
You don‘t want the system to
inflate while someone is working on your vehicle. Your
retailer and the Bravada Service Manual have
information about servicing your vehicle and the air bag
system. To purchase a service manual, see “Service and
Owner Publications”
in the Index.
For up to two minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to
an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part
of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do
so.
The air bag system does not need regular maintenance.

Adding Equipment to Your Air
Bag-Equipped Vehicle
A:
A:
If I add a push bumper or a bicycle rack to the
front
of my vehicle, will it keep the air bags
from working properly?
As long as the push bumper or bicycle rack is
attached to your vehicle
so that the vehicle’s basic
structure isn’t changed, it’s not likely to keep the
air bags from working properly in a crash.
Is there anything I might add to the front of the
vehicle that could keep the air bags from
working properly?
Yes. If you add things that change your vehicle’s
frame, bumper system, front end sheet metal or
height, they may keep
the air bag system from
working properly. Also, the
air bag system may not
work properly
if you relocate any of the air bag
sensors. If you have any questions about
this, you
should contact Customer Assistance before you
modify
your vehicle. (The phone numbers and
addresses for Customer Assistance are in Step Two of
the Customer Satisfaction Procedure in this manual.
See “Customer Satisfaction Procedure” in the Index.)
a
Rear Seat Passengers-. . ’. ’
It’s very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.
Rear passengers who aren’t safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.

Exterior Lamps
Your parking lamp and headlamp switch is on the
driver’s side
of your instrument panel.
Rotate the knob to the right to the parking lamps symbol
to manually turn on:
Parking Lamps
Sidemarker Lamps
Tidillamps
0 License Plate Lamps
Instrument .Panel Lights Rotate
the knob
to the right to the master lamp symbol
to turn on all the lamps listed as well as the headlamps.
Rotate the knob all the way to the left to turn
off your
lamps and put the system
in auto headlamp mode.
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 dim.
Your vehicle is equipped with a light sensor
on the top
of the instrument panel under the radio speaker grill, so
be sure it is not covered, which will cause the system to
be on whenever the ignition
is on.
The system may also turn on your lights when driving
through a parking gzage, heavy overcast weather, a tunnel
or fueling your vehicle in a low-light area. 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
afiect 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.

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 module, the wiring
and the diagnostic module. For more information on the
air
bag system. see “Air Bag“ in the Index.
This light
will come on
when you start your engine,
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
engine or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
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.
Charging System Indicator ._ Light
1 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.

~ . le Knob - Automatic
Operation
I he right knob on the control panel allows you to
choose the direction of air delivery. When the system is
set
for automatic operation, sensors will control the air
delivery mode. Air will come primarily from the floor
or
instrument panel outlets, with some air directed to the
windshield to prevent fogging.
When the system is
in AUTO mode, the air conditioning
light will turn on, and
the recirculation and outside air
lights
turn off. With the system in full auto control
(both the fan and mode knobs
in AUTO), YOLI still
have the ability to override any function. However?
continually overriding the outside air or the A/C
compressor will
limit the ability of the system to cool
the vehicle quickly.
If you push a button for a function which is not
available, the light next to that button
will flash three
times to alert you that it's
not available.
To find your comfort zone, start with the
74°F (23°C)
setting and allow about 20 minutes for the system to
adjust the temperature
if necessary.
With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool
the air.
In cold weather, when the system senses the need
for heat, the airflow will be directed out the floor outlets.
As the
interior temperature approaches a desired
setting,
the blower speed will decrease. To maintain
interior comfort, the airflow will adjust between the
instrument panel air outlets and
floor outlets. On bright
sunny days in cool weather, the airflow may come out
of
the air conditioning and floor outlets (bi-level mode) to
maintain comfort and prevent stuffiness.
To avoid blowing cold air
in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air
temperature, engine coolant temperature or the time
since the engine was last started.
As the coolant
warms
up, the blower fan speed will gradually increase
and air will flow from the heater outlets, with some
airflow to the windshield to prevent fogging under most
normal conditions.
If your vehicle is sitting out on a warm day and you
have the filn set on AUTO, the air
will first flow out of
the floor air outlets for
a few seconds. That is normal.
This is to expel hot air from the air outlets.
As the air is
cooled, the airflow
will move through the air
conditioning outlets.
Be careful
not to put anything over the solar sensor
located around the center of the instrument panel.
This sensor is used by the automatic system
to
regulate temperature.
