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 infoimation on the air bag system, see “Air
Bag” in the Index.
AIR BAG
You will see this light flash
for a few seconds when you

Brake System Warning Light
Your Aurora’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.
This light should come on when you
turn the ignition
key to START.
If it doesn’t
come on then, have it fixed
so it will be ready to warn
you
if there’s a problem. If
this warning light stays on
after you start the engine,
there could be a brake
problem. Have your brake
system inspected right away. If
the light and chime come
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 “Towing
Your Vehicle” in the Index.)
Your brake system may not be working properly
if the brake warning light
is on. Driving with the
brake 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.

Vehicles with hydraulic
brakes have a parking brake
indicator light. When the ignition
is on, this light will
come
on when you set your
parking brake. The light will

you’re driving, your Aurora needs service.
If the regular
brake system warning light isn’t on, you still have brakes, \
but you don’t have anti-lock brakes.

Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE SOON
Your Aurora is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called
OBD I1 (&-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. (In Canada,
OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE SOON
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, which
may prevent more serious damage
to your vehicle. This
system is also designed
to assist your service technician
in correctly diagnosing any malfunction.
ProCarManuals.com

The following may prevent more serious damage to
your vehicle: I 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.
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. Retailer or qualified service center diagnosis
and service
is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Retailer or qualified service center diagnosis and
service may be required.
0 Reduce vehicle speed.
0 Avoid hard accelerations.
0 Avoid steep uphill grades.
If 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
“If
the Light Is On Steady” following.
If the light continues to flash, when
it is safe to do so,
stop the vehicle. Put your vehicle in PARK (P). Turn the
key off, wait at least 10 seconds and restart the engine.
If
the light remains on steady, see “If the Light Is On
Steady” following. If the light is still flashing, follow the
previous steps, and drive the vehicle to your retailer or
qualified service center for service.
ProCarManuals.com

If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
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.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently as designed since small amounts
of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure to install the fuel cap properly.
It
will take a few driving trips to turn the light off. Have you recently
changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not to run
as efficiently as designed. You may
notice this as stalling after start-up, stalling when
you
put the vehicle into gear, misfiring, hesitation on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause
the light
to
turn on.
If you experience this condition, change the fuel brand
you use.
It will require at least one full tank of the
proper fuel
to turn the light off.
If none of the above steps have made the light turn off,
have your retailer or qualified service center check the
vehicle. Your retailer has the proper test equipment and
diagnostic tools
to fix any mechanical or electrical
problems that may have developed.
