2002 Oldsmobile Silhouette ignition

2-98
Retro-Active Reset
Each of the two trip odometers has a feature called
retro
-active reset. This feature can be used to set either
(or both) trip odometer(s) to the number of miles
(kilometers) driven since the ignition was last turned on.
This can be used if you forget to reset your trip
odometer at the beginning of a trip. To use the
retro
-active reset feature, press and hold the trip/reset
button for at least three seconds. The trip odometer will
then display the number of miles (kilometers) driven
since the ignition was last turned on and you began
driving. (If you use the retro
-active reset feature after
you have started the vehicle, but before you begin
moving, the display will show the number of miles
(kilometers) you drove during the last ignition cycle.)
Once you begin driving, the trip odometer will
accumulate mileage. For example, if you have driven
5.0 miles (8.0 km) since you started your vehicle, and
then activate the retro
-active reset feature, the display
will show 5.0 miles (8.0 km). As you drive, the display
will then increase to 5.1 (8.2 km), 5.2 (8.4 km), etc.
Only the trip odometer that is displayed will be affected
by the retro
-active reset so that both trip odometers can
be used separately.
Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the red area, or engine damage may occur.

2-100 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 sensor, the air bag
modules, the wiring and the diagnostic module. For
more information on the air bag system, see ªAir Bagº
in the Index.
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.
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 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.

2-101
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The light
will stay on if your parking brake doesn't release fully.
If it stays on after your parking brake is fully released,
it means you have a brake problem.
Your vehicle's hydraulic brake system is divided into
two parts. If one part isn't working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
United States CanadaThis light should come on briefly when you turn the
ignition key to RUN. If it doesn't come on then,
have it fixed so it will be ready to warn you if there's
a problem.
If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still on, have
the vehicle towed for service. See ªAnti
-Lock Brake
System Warning Lightº and ªTowing Your Vehicleº in
the Index.
CAUTION:
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you've
pulled off the road and stopped carefully, have
the vehicle towed for service.

2-102 Anti-Lock Brake System Warning Light
The anti-lock brake
system warning light
should come on for
a few seconds when
you turn the ignition
key to RUN.
If the anti
-lock brake system warning light stays on
longer than normal after you've started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you're driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you're driving, the anti
-lock brake system needs
service and you don't have anti
-lock brakes.
The anti
-lock brake system warning light should come
on briefly 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.
Traction Control System Warning
Light (Option)
United States Canada
The traction control system warning light may come on
for the following reasons:

If you turn the system off by pressing the TCS
button located in the instrument panel switchbank
the warning light will come on and stay on. To turn
the system back on, press the button again. The
warning light should go off. See ªTraction Control
Systemº in the Index for more information.

2-104 Malfunction Indicator Lamp (Service
Engine Soon Light in the United States
or Check Engine Light in Canada)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
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 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, transaxle,
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 the SERVICE ENGINE SOON
or CHECK ENGINE 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.

2-105
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:

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 ªIf the Light Is On Steadyº following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine. If the light remains on steady, see ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully install
the cap. See ªFilling Your Tankº in the Index. The
diagnostic system can determine if the fuel cap has been
left off or improperly installed. A loose or missing fuel
cap will allow fuel to evaporate into the atmosphere. A
few driving trips with the cap properly installed should
turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out. A few driving trips should turn the light off.

2-107
Fuel Gage
United States Canada
When the indicator nears empty, you still have a little
fuel left, but you should get more soon.
If your fuel is low, the warning message in the message
center will go on. See ªLow Fuel Warning Messageº
later in this section.Your fuel gage tells you about how much fuel you have
left when the ignition is on.
Here are four things that some owners ask about. All
these things are normal and do not indicate that anything
is wrong with the fuel gage.

At the gas station, the gas pump shuts off before the
gage reads full.

It takes a little more (or less) fuel to fill up than the
gage reads. For example, the gage reads half full, but
it took more (or less) than half of the tank's capacity
to fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate empty when the ignition
is turned off.

2-108
Message Center
The message center is located in the instrument
panel cluster. It gives you important safety and
maintenance facts.
Charging System Indicator Message
The charging system
battery symbol will come
on in the message center
when you turn on the
ignition as a check to
show you it is working.
It will remain on as long as the engine is not running. 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 indicator appears in the message
center could drain your battery.
If you must drive a short distance with the message on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
Service Traction System Warning
Message (Option)
United States Canada
If your vehicle has the traction control system and this
message is displayed when you're driving, there may be
a problem with your traction control system. Your
vehicle may need service.
When this message is displayed, the traction
control system will not limit wheel spin. Adjust your
driving accordingly.
