sensor SATURN AURA 2009 Owners Manual

Frontal airbags may inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash speed than
if the vehicle hits an object that does not deform.
If the vehicle hits a narrow object (like a pole), the
airbags could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle, the
airbags could inate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specic vehicle design.
Frontal airbags are not intended to inate during vehicle
rollovers, rear impacts, or in many side impacts.
In addition, the vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to crash
severity. The vehicle has electronic frontal sensors, which
help the sensing system distinguish between a moderate
frontal impact and a more severe frontal impact. For
moderate frontal impacts, dual-stage airbags inate at a
level less than full deployment. For more severe frontal
impacts, full deployment occurs.The vehicle has seat-mounted side impact and
roof-rail airbags. SeeAirbag System on page 1-56.
Seat-mounted side impact and roof-rail airbags are
intended to inate in moderate to severe side crashes.
Seat-mounted side impact and roof-rail airbags will inate
if the crash severity is above the system’s designed
threshold level. The threshold level can vary with specic
vehicle design.
Seat-mounted side impact and roof-rail airbags are
not intended to inate in frontal impacts, near-frontal
impacts, rollovers, or rear impacts. A seat-mounted side
impact airbag is intended to deploy on the side of the
vehicle that is struck. A roof-rail airbag is intended
to deploy on the side of the vehicle that is struck.
In any particular crash, no one can say whether an airbag
should have inated simply because of the damage to a
vehicle or because of what the repair costs were. For
frontal airbags, ination is determined by what the vehicle
hits, the angle of the impact, and how quickly the vehicle
slows down. For seat-mounted side impact and roof-rail
airbags, deployment is determined by the location and
severity of the side impact.

The passenger sensing system works with sensors that
are part of the right front passenger seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger
frontal airbag and seat-mounted side impact airbag
should be enabled (may inate) or not.
According to accident statistics, children are safer when
properly secured in a rear seat in the correct child
restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing
child restraint; a child riding in a forward-facing child
seat; an older child riding in a booster seat; and children,
who are large enough, using safety belts.
A label on the 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:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front passenger
airbag inates. This is because the back of the
rear-facing child restraint would be very close to the
inating airbag. A child in a forward-facing child
restraint can be seriously injured or killed if the right
front passenger airbag inates and the passenger
seat is in a forward position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag and
seat-mounted side impact airbag (if equipped),
no system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag(s) are off.
Secure rear-facing child restraints in a rear seat,
even if the airbag(s) are off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint in
a rear seat.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts of
the front seats, safety belts, the airbag sensing and
diagnostic module, steering wheel, instrument panel,
roof-rail airbag modules, ceiling headliner or pillar
garnish trim, overhead console, front sensors, side
impact sensors, or airbag wiring can affect the
operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position, which
includes sensors that are part of the passenger’s
seat. The passenger sensing system may not
operate properly if the original seat trim is replaced
with non-GM covers, upholstery or trim, or with GM
covers, upholstery or trim designed for a different
vehicle. Any object, such as an aftermarket seat
heater or a comfort enhancing pad or device,
installed under or on top of the seat fabric, couldalso interfere with the operation of the passenger
sensing system. This could either prevent proper
deployment of the passenger airbag(s) or prevent
the passenger sensing system from properly turning
off the passenger airbag(s). SeePassenger Sensing
System on page 1-65.
If you have any questions about this, you should
contact Customer Assistance before you modify
your vehicle. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this manual.
SeeCustomer Satisfaction Procedure on page 7-2.
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:If you have questions, call Customer Assistance.
The phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 7-2.
In addition, your dealer/retailer and the service manual
have information about the location of the airbag sensors,
sensing and diagnostic module and airbag wiring.

Delayed Headlamps
The delayed headlamps feature keeps the headlamps
on for 20 seconds after the key is turned to LOCK/OFF,
then the headlamps automatically turn off.
To override the 20 second delayed headlamp feature
while it is active turn the turn signal/multifunction
lever up one position and then back to AUTO.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional DRL are required on all vehicles rst sold
in Canada. The vehicle has a light sensor on top of the
instrument panel that controls the DRL. Do not cover this
sensor or the head lamps will be on when they are not
needed.The DRL system makes the low-beam headlamps come
on at a reduced brightness when the following conditions
are met:
The ignition is on.
The exterior lamps control is in AUTO.
The exterior lamps control is in the parking lamps
only position (This applies only to vehicles that are
rst sold in Canada).
The light sensor detects daytime light.
The parking brake is released or the vehicle is not in
P (Park).
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps, and instrument panel lights
are not on unless you turn the exterior lamps control to
the parking lamp position.
The regular headlamp system should be turned on
when they are needed.

Automatic Headlamp System
When it is dark enough outside, the automatic headlamp
system turns on the headlamps at the normal brightness
along with other lamps such as the taillamps, sidemarker,
parking lamps, and the instrument panel lights. The radio
lights will also be dim.
The vehicle has a light sensor on top of the instrument
panel that controls the automatic headlamp system.
Do not cover the sensor or the automatic headlamp
system will turn on when it is not needed.
There is a delay in the transition between the daytime
and nighttime operation of the DRL and the automatic
headlamp systems so that driving under bridges or
bright overhead street lights does not affect the system.
The DRL and automatic headlamp systems will only be
affected when the light sensor sees a change in lighting
lasting longer than this delay.
If vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes about one minute for
the automatic headlamp system to change to DRL if it is
light outside. During that delay, the instrument panel
cluster may not be as bright as usual. Make sure the
instrument panel brightness control is in the full bright
position. SeeInstrument Panel Brightness on page 3-16.To idle the vehicle with the automatic headlamp system
off, turn the ignition on and set the exterior light switch to
the off/on position. For vehicles rst sold in Canada, the
transmission must stay in P (Park) for this function.
The regular headlamps should be used when needed.
Fog Lamps
For vehicles with fog lamps, the button for this feature is
located on the instrument panel, to the left of the
steering wheel.
The ignition must be on for the fog lamps to work.
#:Press to turn the fog lamps on or off. An indicator
light comes on when the fog lamps are on.
The parking lamps automatically turn on and off when
the fog lamps are turned on and off.
The fog lamps turn off while the high-beam headlamps
are turned on.
Some localities have laws that require the headlamps to
be on along with the fog lamps.

Do not to cover the sensor located on the top of the
instrument panel near the windshield. This sensor
regulates air temperature based on the intensity of
the sun.
Also do not cover the sensor grille on the lower right
side of the climate control faceplate, as this regulates
the inside temperature.
To avoid blowing cold air at engine start-up in cold
weather, the system delays turning on the fan until
warm air is available. The length of delay depends
on the engine coolant temperature. Turning the fan
knob overrides this delay and changes the fan to
the selected speed.

Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime
sounds for several seconds to remind the front passenger
to buckle their safety belt. This only occurs if the
passenger airbag is enabled. SeePassenger Sensing
System on page 1-65for more information. The
passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then ashes for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger safety belt is buckled, neither the
chime nor the light comes on.
The front passenger safety belt warning light and
chime may turn on if an object is put on the seat such
as a briefcase, handbag, grocery bag, laptop or other
electronic device. To turn off the warning light and or
chime, remove the object from the seat or buckle the
safety belt.
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 1-56.
The airbag readiness light
ashes for a few seconds
when the engine is started.
If the light does not come
on then, have it xed

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure readings
to a receiver located in the vehicle.
Each tire, including the spare (if provided), should be
checked monthly when cold and inated to the ination
pressure recommended by the vehicle manufacturer
on the vehicle placard or tire ination pressure label.
(If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire ination
pressure label, you should determine the proper
tire ination pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one
or more of your tires is signicantly under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inate them to the proper pressure.
Driving on a signicantly under-inated tire causes the
tire to overheat and can lead to tire failure. Under-ination
also reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if under-ination
has not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indicator
is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will ash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur
for a variety of reasons, including the installation of
replacement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to ensure that
the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
SeeTire Pressure Monitor Operation on page 5-55for
additional information.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor
System (TPMS). The TPMS is designed to warn
the driver when a low tire pressure condition exists.
TPMS sensors are mounted onto each tire and wheel
assembly, excluding the spare tire and wheel assembly.
The TPMS sensors monitor the air pressure in the
vehicle’s tires and transmits the tire pressure readings
to a receiver located in the vehicle.
When a low tire pressure
condition is detected, the
TPMS turns on the low
tire pressure warning light
located on the instrument
panel cluster.
At the same time a message to check the pressure in
a specic tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and the
DIC warning message come on at each ignition cycle
until the tires are inated to the correct ination pressure.
Using the DIC, tire pressure levels can be viewed by the
driver. For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays on page 3-43andDIC Warnings and Messages
on page 3-45.
