light SATURN AURA 2010 Workshop Manual

Airbag Readiness Light
The system checks the airbag’s electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the airbag
modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, seeAirbag System on page 2-58.
The airbag readiness light
flashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
fixed immediately.{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also come
on. SeeDIC Warnings and Messages on page 4-42
for more information.

Passenger Airbag Status Indicator
The vehicle has a passenger sensing system. See
Passenger Sensing System on page 2-68for important
safety information. The instrument panel has a
passenger airbag status indicator.
When the vehicle is started, the passenger airbag status
indicator will light ON and OFF, or the symbol for on
and off, for several seconds as a system check. If you
are using remote start to start the vehicle from a
distance, if equipped, you may not see the 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 frontal and seat-mounted side impact
airbags.If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger frontal airbag and seat-mounted side impact
airbag are enabled (may inflate).
If the word OFF or the off symbol is lit on the passenger
airbag status indicator, it means that the passenger
sensing system has turned off the right front passenger
frontal and seat-mounted side impact airbag.
If, after several seconds, both 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 dealer/retailer for service.
{WARNING:
If the airbag readiness light ever comes on and
stays on, it means that something may be wrong
with the airbag system. To help avoid injury to
yourself or others, have the vehicle serviced right
away. SeeAirbag Readiness Light on page 4-28
for more information, including important safety
information. United States

when the ignition key is
turned to START, but
the engine is not running,
as a check to show it
is working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a
problem with the charging system. A charging system
message in the Driver Information Center (DIC) can also
appear. SeeDIC Warnings and Messages on page 4-42
for more information. This light could indicate that
there are problems with a generator drive belt, or that
there is an electrical problem. Have it checked right
away. If the vehicle must be driven a short distance with
the light on, turn off accessories, such as the radio
and air conditioner.
Brake System Warning Light
The vehicle’s hydraulic brake system is divided into two
parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking both
parts need to be working.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.

been pulled off the road and carefully stopped,
have the vehicle towed for service.
This light comes on briefly when the ignition key is
turned to ON/RUN. If it does not, have the vehicle
serviced by your dealer/retailer. If the system is working
normally the indicator light will then go off.
When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The
light stays on if the parking brake does not fully release.
If it stays on after the parking brake is fully released,
it means there is a brake problem.
The Driver Information Center (DIC) may display a
BRAKE FLUID message. SeeDIC Warnings and
Messages on page 4-42for more information.
If the light comes on while driving, pull off the road and
stop carefully. The pedal may be harder to push or it
may go closer to the floor. It may take longer to stop. Try

Electronic Stability Control
(ESC)/Traction Control System
(TCS) Indicator/Warning Light
The Electronic Stability
Control (ESC) system or
the Traction Control
System (TCS)
indicator/warning light
comes on briefly when the
engine is started.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
If this light is on while certain DIC messages display,
this indicates that the ESC and TCS are not working or
are disabled.If this light is on and not flashing, the TCS and
potentially the ESC system have been disabled. Check
the DIC messaging to determine which feature(s) is
no longer functioning and whether it is because of the
driver turning off the feature(s), or because the system is
not working properly and the vehicle requires service.
If the TCS is disabled, wheel spin is not limited. If
the ESC system is disabled, the system does not aid in
maintaining directional control of the vehicle.
If the indicator/warning light is on and flashing, the TCS
or the ESC system is actively working. Check the
DIC messaging for details to determine which system is
working. If the LOW TRACTION message appears,
the system is limiting wheel spin. If the ESC ACTIVE
message appears, the system is aiding in maintaining
directional control of the vehicle.

This light comes on briefly
while starting the vehicle.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
Notice:Driving with the engine coolant temperature
warning light on could cause the vehicle to
overheat. SeeEngine Overheating on page 6-28. The
vehicle’s engine could be damaged, and it might
not be covered by the vehicle warranty. Never drive
with the engine coolant temperature warning
light on.
The engine coolant temperature warning light comes on
when the engine has overheated.
If this happens pull over and turn off the engine as soon
as possible. SeeEngine Overheating on page 6-28
for more information.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, the light comes
on and a chime sounds, the engine is too hot. It means
that the engine coolant has overheated.

Tire Pressure Light
For vehicles with a tire pressure monitoring system, this
light comes on briefly when the engine is started. It
provides information about tire pressures and the Tire
Pressure Monitoring System.
When the Light is On Steady
This indicates that one or more of the tires are
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC) on page 4-39for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. SeeInation - Tire Pressure on page 6-51for
more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about
a minute and stays on steady for the remainder of
the ignition cycle. This sequence repeats with every
ignition cycle. SeeTire Pressure Monitor Operation on
page 6-54for more information.
Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It
ensures that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on, but
the engine is not running,
as a check to show it
is working. If it does not,
have the vehicle serviced
by your dealer/retailer.
4-34
ProCarManuals.com

If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.
Malfunctions often are indicated by the system before
any problem is apparent. Being aware of the light
can prevent more serious damage to the vehicle. This
system assists the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is continually driven with this
light on, after a while, the emission controls
might not work as well, the 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 the vehicle warranty.
Notice:Modications made to the engine,
transmission, exhaust, intake, or fuel system of the
vehicle or the replacement of the original tires
with other than those of the same Tire Performance
Criteria (TPC) can affect the vehicle’s emission
controls and can cause this light to come on.
Modications to these systems could lead to costly
repairs not covered by the vehicle warranty. This
could also result in a failure to pass a required
Emission Inspection/Maintenance test. See
Accessories and Modifications on page 6-3.This light comes on during a malfunction in one of
two ways:
Light Flashing:A misfire condition has been detected.
A misfire increases vehicle emissions and could
damage the emission control system on the vehicle.
Diagnosis and service might be required.
To prevent more serious damage to the vehicle:
•Reduce vehicle speed.
•Avoid hard accelerations.
•Avoid steep uphill grades.
•If towing a trailer, reduce the amount of cargo being
hauled as soon as it is possible.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park the vehicle.
Turn the key off, wait at least 10 seconds, and restart
the engine. If the light is still flashing, follow the previous
steps and see your dealer/retailer for service as soon
as possible.

Light On Steady:An emission control system
malfunction has been detected on the vehicle. Diagnosis
and service might be required.
An emission system malfunction might be corrected by
doing the following:
•Make sure the fuel cap is fully installed. SeeFilling
the Tank on page 6-10. The diagnostic system can
determine if the fuel cap has been left off or
improperly installed. A loose or missing fuel cap
allows fuel to evaporate into the atmosphere. A few
driving trips with the cap properly installed should
turn the light off.
•If the vehicle has been driven through a deep
puddle of water, the vehicle’s electrical system
might be wet. The condition is usually corrected
when the electrical system dries out. A few driving
trips should turn the light off.
•Make sure to fuel the vehicle with quality fuel. Poor
fuel quality causes the engine not to run as
efficiently as designed and can cause: stalling after
start-up, stalling when the vehicle is changed
into gear, misfiring, hesitation on acceleration, or
stumbling on acceleration. These conditions
might go away once the engine is warmed up.
If one or more of these conditions occurs, change
the fuel brand used. It will require at least one
full tank of the proper fuel to turn the light off.
SeeGasoline Octane on page 6-6.If none of the above have made the light turn off, your
dealer/retailer can check the vehicle. The dealer/retailer
has the proper test equipment and diagnostic tools to
fix any mechanical or electrical problems that might have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
might begin programs to inspect the emission control
equipment on the vehicle. Failure to pass this inspection
could prevent getting a vehicle registration.
Here are some things to know to help the vehicle pass
an inspection:
•The vehicle will not pass this inspection if the check
engine light is on with the engine running, or if the
key is in ON/RUN and the light is not on.
•The vehicle will not pass this inspection if the
OBD II (on-board diagnostic) system determines
that critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if the battery has recently been
replaced or if the battery has run down. The
diagnostic system is designed to evaluate critical
emission control systems during normal driving.
4-36
ProCarManuals.com

This can take several days of routine driving. If this
has been done and the vehicle still does not
pass the inspection for lack of OBD II system
readiness, your dealer/retailer can prepare
the vehicle for inspection.
Oil Pressure Light
{WARNING:
Do not keep driving if the oil pressure is low. The
engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
This light comes on briefly while starting the engine. If it
does not, have the vehicle serviced by your dealer/
retailer. If the system is working normally the indicator
light then goes off.
If the light comes on and stays on, it means that oil is
not flowing through the engine properly. The vehicle
could be low on oil and it might have some other system
problem.
