light SATURN ION 2007 Service Manual

Airbag Readiness Light
There is an airbag readiness light on the
instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical
system for malfunctions. The light tells you if there
is an electrical problem. The system check
includes the airbag sensor, the airbag modules,
the wiring and the crash sensing and diagnostic
module. For more information on the airbag
system, seeAirbag System on page 68.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should go
out. This means the
system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should ash for a few
seconds when you turn the ignition key to RUN.
If the light does not come on then, have it xed so
it will be ready to warn you if there is a problem.

Passenger Airbag Status Indicator
If your vehicle has one of the indicators pictured in
the following illustrations, then your vehicle has
a passenger sensing system.
When the ignition key is turned to RUN or START,
the passenger airbag status indicator will light
ON and OFF, or the symbol for on and off,
for several seconds as a system check. Then,
after several more seconds, the status indicator
will light either ON or OFF, or either the on
or off symbol to let you know the status of the
right front passenger’s frontal airbag.
If the word ON or the on symbol is lit on the
passenger airbag status indicator, it means that
the right front passenger’s frontal airbag is enabled
(may inate).{CAUTION:
If the on indicator comes on when you have
a rear-facing child restraint installed in the
right front passenger’s seat, it means that
the passenger sensing system has not
turned off the passenger’s frontal airbag.
A child in a rear-facing child restraint can
be seriously injured or killed if the right
front passenger’s airbag inates. This is
because the back of the rear-facing child
restraint would be very close to the
inating airbag. Do not use a rear-facing
child restraint in the right front passenger’s
seat if the airbag is turned on.
Your vehicle has a rear seat that will accommodate
a rear-facing child restraint. A label on your sun
visor says, “Never put a rear-facing child seat
in the front.” This is because the risk to the
rear-facing child is so great, if the airbag deploys.

{CAUTION:
Even though the passenger sensing
system is designed to turn off the
passenger’s frontal airbag if the system
detects a rear-facing child restraint, no
system is fail-safe, and no one can
guarantee that an airbag will not deploy
under some unusual circumstance, even
though it is turned off. We recommend
that rear-facing child restraints be secured
in the rear seat, even if the airbag is off.
If the word OFF or the off symbol is lit on the
airbag status indicator, it means that the
passenger sensing system has turned off the right
front passenger’s frontal airbag. SeePassenger
Sensing System on page 77for more on this,
including important safety information.If, after several seconds, all status indicator lights
remain on, or if there are no lights at all, there
may be a problem with the lights or the passenger
sensing system. See your retailer for service.
{CAUTION:
If the off indicator and the airbag
readiness light ever come on together, it
means that something may be wrong with
the airbag system. If this ever happens,
have the vehicle serviced promptly,
because an adult-size person sitting in the
right front passenger seat may not have
the protection of the frontal airbag. See
Airbag Readiness Light on page 167.

Your vehicle’s hydraulic brake system is divided
into two parts. If one part is not working, the other
part can still work and stop you. For good
braking, though, you need both parts working well.
If the brake system warning light comes on,
there is a brake problem. Have your brake system
inspected right away.
When the ignition is on, the BRAKE light will come
on when you set your parking brake. The light
will stay on if your parking brake does not release
fully. A chime will also sound if the parking
brake is not fully released and the vehicle is
moving. If it stays on after your parking brake is
fully released, it means you have a brake problem.
The BRAKE light will also come on to indicate a
low brake uid level. SeeBrakes on page 308
for more information.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 oor. It may take longer to
stop. Make sure the parking brake is fully released.
Turn the ignition off and wait several seconds to
restart vehicle, if the light is still on, have the
vehicle towed for service. SeeTowing Your
Vehicle on page 256.
{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 have pulled
off the road and stopped carefully, have
the vehicle towed for service.

Anti-Lock Brake System
Warning Light
If your vehicle has anti-lock brakes, the anti-lock
brake system (ABS) warning light will come
on briey, as a check, when you start your vehicle.
If it does not, have your vehicle serviced so that
the light works properly when it needs to.
The ABS light is located
in the instrument panel
cluster, to the left of
the engine coolant
temperature gage.
If the light stays on longer than a few seconds
after you start your engine, or comes on and stays
on while you are driving, try resetting the system.To reset the system, do the following:
1. If you are driving, pull over when it is safe to
do so.
2. Be sure the vehicle is in PARK (P).
3. Turn off the ignition.
4. Then restart the engine.
If the light remains on after resetting the system or
comes on again while driving, your vehicle
needs service. If the ABS light is on, but the
regular brake system warning light is not on, the
anti-lock brakes are not working properly, but
the regular brakes are still functioning. Have your
vehicle serviced right away. If both brake lights
are on, you do not have anti-lock brakes, and
there’s a problem with your regular brakes as well.
Have your vehicle towed for service. SeeTowing
Your Vehicle on page 256.
The anti-lock brake system warning light should
come on briey when you turn the ignition
key to RUN. If the light does not come on then,
have it xed so it will be ready to warn you if there
is a problem.

Engine Coolant Temperature Gage
This gage measures the
temperature of the
vehicle’s engine coolant.
If the pointer moves into the shaded area, your
engine is too hot, the CHK GAGE message
will appear and a chime will sound to alert you to
the engine coolant temperature gage. See
Check Gage Message on page 184for more
information. If you have been operating your
vehicle under normal driving conditions, you should
pull off the road and stop your vehicle, be sure
the air conditioning is off, let the engine idle for a
few minutes, then turn off the engine.On vehicles with the 2.2L engine, under severe
conditions – hot ambient temperature, steep
grades and towing – your vehicle may experience
more transaxle shifting to avoid engine coolant
overheating. This is temporary and normal under
these conditions. This does not require engine
or transaxle service.
If your engine control system detects a failure in
the engine coolant temperature circuit, the
malfunction indicator lamp light will come on. The
coolant gage may read all the way hot or cold.
The engine cooling fan will be turned on to protect
the engine and transaxle. SeeMalfunction
Indicator Lamp on page 174for more information.
Notice:Driving with the engine coolant
temperature gage indicator in the shaded area
could cause your vehicle to overheat. Your
vehicle could be damaged, and it might not be
covered by your warranty. Never drive with
the engine coolant temperature gage indicator
in the shaded area.

Malfunction Indicator Lamp
Check Engine Light
Your vehicle has 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 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 awhile, the emission controls
might not work as well, your vehicle’s fuel
economy might not be as good, and the engine
might not run as smoothly. This could lead
to costly repairs that might not be covered by
your warranty.
Notice:Modications 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 this light to come on. Modications 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. SeeAccessories
and Modifications on page 270.

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 does not
come on, have it repaired. This light will also
come on during a malfunction in one of two ways:
Light Flashing— A misre condition has
been detected. A misre increases vehicle
emissions and may damage the emission
control system on your vehicle. Diagnosis and
service may be required.
Light On Steady— An emission control
system malfunction has been detected on your
vehicle. 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 ashing and remains on steady,
see “If the Light Is On Steady” following.
If the light continues to ash, 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 “If the Light Is On Steady”
following. If the light is still ashing, follow the
previous steps, and see your retailer for service as
soon as possible.

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. SeeFilling the Tank on page 275.
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.Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 272. 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, misring, 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 one or more of these conditions,
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, your retailer can check the vehicle. Your
retailer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.
