2006 Chevrolet Cobalt Owner ManualM

In many crashes severe enough to inate an airbag,
windshields are broken by vehicle deformation. Additional
windshield breakage may also occur from the right front
passenger airbag.
Airbags are designed to inate only once. After an
airbag inates, you will need some new parts for your
airbag system. If you do not get them, the airbag
system will not be there to help protect you in another
crash. A new system will include airbag modules and
possibly other parts. The service manual for your
vehicle covers the need to replace other parts.
Your vehicle is equipped with a crash sensing and
diagnostic module which records information after a
crash. SeeVehicle Data Collection and Event Data
Recorders on page 7-9.
Let only qualied technicians work on your airbag
system. Improper service can mean that your airbag
system will not work properly. See your dealer for
service.
Passenger Sensing System
If your vehicle has one of the indicators pictured in the
following illustrations, then your vehicle has a passenger
sensing system for the right front passenger’s position.
A passenger airbag status indicator on the instrument
panel will be visible when you turn your ignition key to
START or RUN. The words ON and OFF, or the symbol
for ON and OFF, will be visible on the instrument panel
during the system check. When the system check is
complete, either the word ON or the word OFF, or the
symbol for ON or the symbol for OFF will be visible.
SeePassenger Airbag Status Indicator on page 3-26.
The passenger sensing system will turn off the right
front passenger’s frontal airbag under certain conditions.
The driver’s airbag and the side airbags (if equipped)
are not part of the passenger sensing system.United States
Canada
1-62

If a person of adult-size is sitting in the right front
passenger’s seat, but the off indicator is lit, it could be
because that person is not sitting properly in the seat.
If this happens, turn the vehicle off and ask the person to
place the seatback in the fully upright position, then sit
upright in the seat, centered on the seat cushion, with the
person’s legs comfortably extended. Restart the vehicle
and have the person remain in this position for about two
minutes. This will allow the system to detect that person
and then enable the passenger’s airbag.
{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, 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’s seat may not have the protection
of the frontal airbag. SeeAirbag Readiness
Light on page 3-25for more on this, including
important safety information.
1-65

Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates. You
may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system. SeeAdding Equipment to Your
Airbag-Equipped Vehicle on page 1-67for more
information about modications that can affect how
the system operates.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.
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. You do not want the system to
inate while someone is working on your vehicle.
Your dealer 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 7-14.
{CAUTION:
For up to 10 seconds after the ignition key 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.
The airbag system does not need regular maintenance.

rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a

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.
2-16

To program the new key do the following:
1. Verify that the new key has a
1stamped on it.
2. Insert the already programmed key in the ignition
and start the engine. If the engine will not start, see
your dealer for service.
3. After the engine has started, turn the key to OFF,
and remove the key.
4. Insert the key to be programmed and turn it to the
RUN position within ve seconds of the original key
being turned to the OFF position.
5. The security light will turn off once the key has
been programmed.
6. Repeat Steps 1 through 5 if additional keys are to
be programmed.
If you are ever driving and the security light comes on
and stays on, you may be able to restart your engine if
you turn it off. Your PASS-Key
®III+ system, however,
is not working properly and must be serviced by
your dealer. Your vehicle is not protected by the
PASS-Key
®III+ system at this time.
If you lose or damage your PASS-Key
®III+ key, see
your dealer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Starting and Operating
Your Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Do not exceed
5,000 engine rpm. Avoid downshifting to brake,
or slow, the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new
brake linings are not yet broken in. Hard stops
with new linings can mean premature wear
and earlier replacement. Follow this breaking-in
guideline every time you get new brake
linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer (Automatic Transaxle) on page 4-39or
Towing a Trailer (Manual Transaxle) on
page 4-46for the trailer towing capabilities of
your vehicle and more information.
Following break-in, engine speed and load can be
gradually increased.
2-17

Ignition Positions
With the key in the ignition switch, you can turn it to
four different positions.
Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is all the way in. If
it is, turn the steering wheel left and right while you
turn the key hard. If none of this works, then
your vehicle needs service.
9(LOCK):This position locks your steering column.
It is a theft-deterrent feature. You will only be able
to remove your key when the ignition is turned to LOCK.
If you have an automatic transaxle, the ignition switch
cannot be turned to LOCK unless the shift lever is
in PARK (P).
If you have a manual transaxle, the ignition switch can
be turned to LOCK in any shift lever position.
{CAUTION:
If you have a manual transaxle removing the key
from the ignition switch will lock the steering
column and result in a loss of ability to steer the
vehicle. This could cause a collision. If you need
to turn the engine off while the vehicle is
moving, turn the key to ACC.
ACC (ACCESSORY):This position operates some of
your electrical accessories. It unlocks the steering wheel
and ignition.
