sensor OLDSMOBILE SILHOUETTE 1998 Owners Manual

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 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 sensors are activated and driver’s safety belt
usage at deployment.
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 retailer
for service.
I 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.

If your vehicle ever gets into a lot of water -- such as
water up to the carpeting or higher
-- or if water enters
your vehicle and soaks the carpet, the air bag controller
can be soaked and ruined.
If this ever happens, and then
you start your vehicle, the damage could make the
frontal and side impact air bags inflate and safety belt
pretensioners activate, even if there’s no crash. You
would have to replace the air bags, all the sensors and
related parts, parts of the safety belt system and parts
of
the driver and right front passenger’s seatbacks. If your
vehicle is ever in a
flood, or if it’s exposed to water that
soaks the carpet, you can avoid needless repair costs by
turning off the vehicle immediately. Don’t let anyone
start the vehicle, even to tow it, unless the battery cables
are first disconnected.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag systems in several places
around your vehicle. Your retailer and the Silhouette
Service Manual have information about servicing your
vehicle and the
air bag systems. To purchase a service
manual, see “Service and Owner Publications” in
the Index.
For up to 10 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 systems. Be sure
to follow proper
service procedures, and make sure the person
performing work for you is qualified to do
so.
~~ ~~
The air bag systems do not need regular maintenance.

NOTICE:
If’ your vehicle seems to start up rather slowly, or
if it seems not to shift gears as you go faster,
something may be wrong with a transaxle system
sensor.
If you drive very far that way, your
vehicle can be damaged.
So, if this happens, have
your vehicle serviced right away. Until then, you
can use
SECOND (2) when you are driving less
than
35 mph (55 km/h) and THIRD (3) for
higher speeds. FIRST
(1): This position
gives you even more power
(but lower fuel economy) than SECOND (2). You can
use it on very steep hills, or in deep snow or mud. If the
selector lever is put in
FIRST (1), the transaxle won’t
downshift into first gear until the vehicle is going
slow enough.
NOTICE:
If your front wheels can’t rotate, don’t try to
drive. This might happen
if you were stuck in
very deep sand or mud or were up against a solid
object. You could damage your transaxle.
Also, if you stop when going uphill, don’t hold
your vehicle there with
only the accelerator
pedal. This could overheat and damage the
transaxle. Use your brakes or shift into PARK
(P)
to hold your vehicle in position on a hill.

A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn’t covered. The DRL system
will make your front parking and turn signal lamps
come on in daylight when:
The ignition is on,
the headlamp switch is off and
the parking brake is released.
When the DRL are on, only your front parking and turn
signal lamps will be
on. Your instrument panel won’t be
lit up.
When it’s dark enough outside, the exterior lamps will
come on automatically. When it’s bright enough outside,
the exterior lamps will
go out and the DRL will turn on.
Of course, you may still turn on the headlamps any time
you need to.
To idle your vehicle with the DRL or exterior lamps off,
set the parking brake while the ignition is in
OFF or
LOCK. Then start the vehicle. The DRL will stay
off
until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Fog Lamps
The fog lamps switch is
located in the instrument
panel switchbank. Push the
fog lamp symbol on the
rocker button to turn on
the lamps.
The green indicator light will glow. Push the ribbed
part of
the switch to turn them off. The indicator light will go off.
Your parking lamps or headlamps must be on for your
fog lamps to go on.
When your DRL are on, the headlamps switch must first
be turned from the off position before the fog lamps can
be turned on. At night, when DRL automatically turns
on your headlamps, the fog lamps can be turned on
when the headlamps switch is in any position.
Your fog lamps will go off when you switch to high
beams. Using your high beams in fog is not recommended.

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.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts.
The safety belt light will
also come on and stay on
for about
70 seconds. 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 a deployed 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
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.

dash
“--” is displayed.
Trip Computer
There are five trip computer displays which may be
stepped through by pushing the MODE button. The
information will appear in the following order:
Average Fuel Economy (AVG ECON): This shows
the average fuel economy since the last reset.
Instantaneous Fuel Economy (INST ECON):
This shows fuel economy for the most recent second
of driving.
Trip Range (RANGE): This shows the estimated
distance that can be traveled with the remaining fuel.
The fuel economy used to calculate range is based on
the last few hours of driving.
0 Trip Fuel Used (FUEL USED): This shows the
accumulated fuel used since the last reset.
Average Speed (AVG SPEED): This shows the
average speed since the last reset.
Resetting the Trip Computer
Press and hold the MODE and EM buttons for at least
two seconds. The reset is acknowledged with the display
showing all segments on for a period of half a second.
A reset can only be done in AVG ECON, FUEL USED
and AVG SPEED displays. Resetting affects all three
displays regardless
of which display you are in.
