2008 CHEVROLET MALIBU sensor

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’s seat. The sensors
are designed to detect the presence of a properly-seated
occupant and determine if the right front passenger’s
frontal airbag and seat-mounted side impact airbag
should be enabled (may inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
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 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:
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
CAUTION: (Continued)
CAUTION: (Continued)
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.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle
and the airbag system. To purchase a service manual,
seeService Publications Ordering Information on
page 7-16.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected, an
airbag can still inate during improper service.
You can be injured if you are close to an
airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
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.
1-70

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, could also 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.

Headlamps on Reminder
If you open the driver’s door and turn off the
ignition while leaving the lamps on, you will hear a
warning chime.
Headlamps Off in Park
This feature works when the ignition is in the ON/RUN
position and it is dark outside. To turn the headlamps
off when it is dark outside but keep other exterior lights
on, turn the exterior lamp control to the parking lamp
position.
To turn on the headlamps along with the other lamps
when it is dark outside, turn the exterior lamp control to
the AUTO or headlamp position.
This function does not work for vehicles rst sold in
Canada.
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. DRL are helpful in many different driving conditions,
but they can be especially helpful in the short periods
after dawn and before sunset. 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. Make sure it is not covered, 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 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.
As with any vehicle, you should turn on the regular
headlamp system 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.
Your vehicle has a light sensor on top of the instrument
panel that controls the automatic headlamp system.
Make sure it is not covered or the automatic headlamp
system will be 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. See “Instrument Panel Brightness
Control” underInstrument 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 PARK (P) for this
function.
The regular headlamps should be used when needed.

Overhead Ambient Lighting
These lamps will automatically turn on and off as
controlled by the light sensor located on top of the
instrument panel.
Rear Reading Lamps
The vehicle’s dome lamp may have two rear reading
lamps. Press the lens of the reading lamps to turn them
on or off.
Trunk Lamp
The trunk lamp comes on when the trunk is open and
turns off when it is closed.
Battery Run-Down Protection
Your vehicle has a battery run-down protection feature
designed to protect the vehicle’s battery.
When any interior lamp (trunk, reading, or visor vanity)
is left on while the ignition is turned off, the battery
run-down protection system will automatically shut the
lamp(s) off after 20 minutes. This will avoid draining
the battery.
To reactivate the interior lamps, do one of the following:
Turn on the ignition.
Turn the exterior lamp control off and then on.
Open a door.
Press any Remote Keyless Entry (RKE) transmitter
button (if equipped).
Press the remote trunk release button.
Press the power door lock switch.
The battery run-down feature will also be activated
when any door on the vehicle is left open and the
ignition is in LOCK/OFF.

Power Outlet 115 Volt Alternating
Current
Your vehicle may have a power outlet that can be used
to plug in electrical equipment that uses a maximum
limit of 150 watts.
The power outlet is located
on the rear of the center
console.
An indicator light on the outlet turns on to show it is in
use. The light comes on when the ignition is in ON/RUN
and equipment requiring less than 150 watts is
plugged into the outlet, and no system fault is detected.The indicator light does not come on when the ignition
is in LOCK/OFF or if no equipment is plugged into
the outlet.
If you try to connect equipment using more than
150 watts or a system fault is detected, a protection
circuit shuts off the power supply and the indicator light
turns off. To reset the circuit, unplug the item and
plug it back in or turn the Remote Accessory Power
(RAP) off and then back on. SeeRetained Accessory
Power (RAP) on page 2-24. The power restarts
when equipment that operates within the limit is plugged
into the outlet and a system fault is not detected.
The power outlet is not designed for the following
electrical equipment and may not work properly if these
items are plugged into the power outlet:
Equipment with high initial peak wattage such as:
compressor-driven refrigerators and electric
power tools.
Other equipment requiring an extremely stable
power supply such as: microcomputer-controlled
electric blankets, touch sensor lamps, etc.
