ECU CHEVROLET COBALT 2006 1.G Owner's Manual

The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety belt.
The sensors are designed to detect the presence of
a properly-seated occupant and determine if the
passenger’s frontal 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.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat.
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:
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.
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 you need to 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.
1-63

The passenger sensing system is designed to turn off
the right front passenger’s frontal airbag if:
the right front passenger seat is unoccupied
the system determines that an infant is present in a
rear-facing infant seat
the system determines that a small child is present
in a forward-facing child restraint
the system determines that a small child is present
in a booster seat
a right front passenger takes his/her weight off of
the seat for a period of time
the right front passenger seat is occupied by a
smaller person, such as a child who has outgrown
child restraints
or if there is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has turned off the
passenger’s frontal airbag, the off indicator on the
instrument panel will light and stay lit to remind you that
the airbag is off.
If a child restraint has been installed and the on
indicator is lit, turn the vehicle off. Remove the child
restraint from the vehicle and reinstall the child restraint
following the child restraint manufacturer’s directions
and refer toSecuring a Child Restraint in the Right Front
Seat Position on page 1-50.If after reinstalling the child restraint and restarting the
vehicle, the on indicator is still lit, check to make sure that
the vehicle’s seatback is not pressing the child restraint
into the seat cushion. If this happens, slightly recline the
vehicle’s seatback and adjust the seat cushion if
possible. Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens, adjust
the head restraint.
If the on indicator is still lit, secure the child in the child
restraint in a rear seat position in the vehicle and
check with your dealer.
The passenger sensing system is designed to enable
(may inate) the right front passenger’s frontal airbag
anytime the system senses that a person of adult size is
sitting properly in the right front passenger’s seat. When
the passenger sensing system has allowed the airbag to
be enabled, the on indicator will light and stay lit to remind
you that the airbag is active.
For some children who have outgrown child restraints
and for very small adults, the passenger sensing system
may or may not turn off the right front passenger’s frontal
airbag, depending upon the person’s seating posture and
body build. Everyone in your vehicle who has
outgrown child restraints should wear a safety belt
properly — whether or not there is an airbag for that
person.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end or side sheet
metal or height, they may keep the airbag system
from working properly. Also, the airbag system may
not work properly if you relocate any of the airbag
sensors. 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:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the center console), or the
instrument panel can affect the operation of the
airbag system. 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.

Automatic Door Lock
If your vehicle has power door locks, the doors will
automatically lock when the shift lever is moved out of
PARK (P) for a vehicle with an automatic transmission.
For a vehicle with a manual transmission, the speed
must be greater than 5 mph (8 km/h).
The automatic door locking feature cannot be disabled.
Programmable Automatic
Door Unlock
If your vehicle has power locks, it has a programmable
automatic door unlock feature.
The doors can be programmed through the Driver
Information Center (DIC) to automatically unlock several
ways. SeeDIC Vehicle Personalization on page 3-43
for more information.
Rear Door Security Locks
Your vehicle has rear door security locks. These
prevent passengers from opening the rear doors from
the inside.
The rear door security
locks are located on the
inside edge of each
rear door. You must open
the rear doors to access
them. The label depicting
lock and unlock positions
is located near the lock.
To set the locks, do the following:
1. Insert the key into the security lock slot and
turn it so the slot is in the horizontal position.
2. Close the door.Security Lock Label
shown
2-9

When you want to open a rear door when the security
lock is on, do the following:
1. Unlock the door using the remote keyless entry
transmitter, if the vehicle has one, the power door
lock switch, or by lifting the rear door manual lock.
2. Open the door from the outside.
To cancel the rear door security lock, do the following:
1. Unlock the door and open it from the outside.
2. Insert the key into the security lock slot and turn it
so the slot is in the vertical position.
Lockout Protection
If your vehicle has power door locks, it will have this
feature. If you press the power door lock switch
when the key is in the ignition and any door is open, all
the doors will lock and the driver’s door will unlock.
Be sure to remove the key from the ignition when locking
your vehicle.
The lockout protection can be overridden by pressing
and holding the power door lock in the lock position for
three seconds.
Trunk
To release the trunk lid from the outside, use the key or
the remote keyless entry transmitter, if equipped.
{CAUTION:
It can be dangerous to drive with the trunk lid
open because carbon monoxide (CO) gas can
come into your vehicle. You cannot see or
smell CO. It can cause unconsciousness and
even death. If you must drive with the trunk lid
open or if electrical wiring or other cable
connections must pass through the seal
between the body and the trunk lid:
Make sure all other windows are shut.
Turn the fan on your heating or cooling
system to its highest speed and select the
control setting that will force outside air
into your vehicle. See Climate Control
System.
If you have air outlets on or under the
instrument panel, open them all the way.
SeeEngine Exhaust on page 2-32.

Remote Trunk Release
To open the trunk from
inside the vehicle, press
the remote trunk release
button located inside
the driver’s storage
compartment located on
the lower left side of
the instrument panel.
SeeInstrument Panel Overview on page 3-4orDriver’s
Storage Compartment on page 2-37.
The remote trunk release works when the ignition is
either off or in ACC, or the vehicle speed is less
than 2 mph (3 km/h).
Emergency Trunk Release Handle
Notice:Do not use the emergency trunk release
handle as a tie-down or anchor point when securing
items in the trunk as it could damage the handle.
The emergency trunk release handle is only
intended to aid a person trapped in a latched trunk,
enabling them to open the trunk from the inside.
There is a glow-in-the-dark emergency trunk release
handle located on the inside of the trunk lid of your
vehicle. This handle will glow following exposure to light.
Pull the release handle and push the trunk lid open
from the inside to open the trunk.
2-11

Visor Vanity Mirror
Your vehicle may have a driver’s side vanity mirror.
Swing down the sun visor and lift the cover to expose
the mirror.
Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Content Theft-Deterrent
Your vehicle may have a
content theft-deterrent
alarm system.
Arming the System
With the ignition off, you can arm the system by doing
any one of the following:
Press the remote keyless entry transmitter lock
button.
Press the power door lock switch while the driver’s
door is open.
The system will arm after either of these things occur:
Thirty seconds after all the doors are closed.
Sixty seconds with any door open.
If you press the lock button on the transmitter a second
time while all the doors are closed, the system will
arm immediately. The system will still arm in 60 seconds
if a door is open. When the open door is closed, it will
also become armed.
The security light, located on the instrument panel
cluster, will turn on to indicate that arming has been
initiated. Once the system is armed, the security light will
ash once every three seconds.
If the security light is ashing twice per second, this
means that a door is open.
If you do not want to arm the system, you may lock the
car with the manual lock knobs on the doors.
2-14

Disarming the System
You can disarm the system by doing any one of the
following:
Press the remote keyless entry transmitter unlock
button.
Turn the ignition on.
If the system is armed and the trunk is opened using
the trunk release button on the transmitter, the system
will temporarily disarm itself and re-arm when the
trunk has been closed. This allows you to exit the
vehicle, lock the doors using the transmitter, and open
the trunk using the transmitter without having to
disarm and re-arm the system.
Once the system is disarmed, the security light will stop
ashing.
How the System Alarm is Activated
If the system is armed, it can be activated by either:
Opening the driver’s door or trunk. This will
cause a ten second pre-alarm chirp followed by a
thirty second full alarm of horn and lights.
Opening any other door. This will immediately
cause a full alarm of horn and lights for
thirty seconds.
When an alarm event has nished, the system will
re-arm itself automatically.
How to Turn Off the System Alarm
To turn off the system alarm, do one of the following:
Press the lock button on the remote keyless
entry transmitter. The system will then re-arm itself.
Press the unlock button on the remote keyless entry
transmitter. This will also disarm the system.
Insert the key in the ignition and turn it on. This will
also disarm the system.
How to Detect a Tamper Condition
If you hear three chirps when you press the unlock, lock,
or trunk release buttons on the remote keyless
transmitter, it means that the content theft security
system alarm was previously activated.

PASS-Key
®III+ uses a radio frequency transponder in
the key that matches a decoder in your vehicle.
PASS-Key®III+ Operation
Your vehicle is equipped with PASS-Key®III+
(Personalized Automotive Security System)
theft-deterrent system. PASS-Key
®III+ is a passive
theft-deterrent system. This means you do not have to
do anything special to arm or disarm the system. It
works when you insert or remove the key from
the ignition.
When the PASS-Key
®III+ system senses that someone
is using the wrong key, it prevents the vehicle from
starting. Anyone using a trial-and-error method to start
the vehicle will be discouraged because of the high
number of electrical key codes.When trying to start the vehicle if the engine does not
start and the security light on the instrument panel
cluster comes on, the key may have a damaged
transponder. Turn the ignition off and try again.
If the engine still does not start, and the key appears to be
not damaged, try another ignition key. At this time, you
may also want to check the fuse, seeFuses and Circuit
Breakers on page 5-98. If the engine still does not start
with the other key, your vehicle needs service. If your
vehicle does start, the rst key may be faulty. See your
dealer who can service the PASS-Key
®III+ to have a
new key made. In an emergency, contact Roadside
Assistance. SeeRoadside Assistance Program on
page 7-6.
It is possible for the PASS-Key
®III+ decoder to “learn”
the transponder value of a new or replacement key.
Up to 10 keys may be programmed for the vehicle. The
following procedure is for programming additional keys
only. If all the currently programmed keys are lost or do
not operate, you must see your dealer or a locksmith who
can service PASS-Key
®III+ to have keys made and
programmed to the system.
See your dealer or a locksmith who can service
PASS-Key
®III+ to get a new key blank that is cut
exactly as the ignition key that operates the system.
