2010 CHEVROLET HHR ECU

Airbag System
The vehicle has the following airbags:
.A frontal airbag for the driver.
.A frontal airbag for the right front passenger.
The vehicle may have the following airbags:
.A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
.A roof-rail airbag for the right front passenger and
the passenger seated directly behind that
passenger.
All of the airbags in your vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and on
the instrument panel for the right front passenger.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim. Even if you do not have a right front passenger seat in
your vehicle there is still an active frontal airbag in the
right side of the instrument panel. Do not place cargo in
front of this airbag.
{WARNING:
Be sure that cargo is not near an airbag. In a
crash, an inflating airbag might force that object
toward a person. This could cause severe injury
or even death. Secure objects away from the
area in which an airbag would inflate. For more
information, see
Where Are the Airbags?
on
page 2‑63
and Loading the Vehicleon
page 5‑24
.
Airbags are designed to supplement the protection
provided by safety belts. Even though today's airbags
are also designed to help reduce the risk of injury from
the force of an inflating bag, all airbags must inflate very
quickly to do their job.
2-60

{WARNING:
Children who are up against, or very close to, any
airbag when it inflates can be seriously injured or
killed. Airbags plus lap-shoulder belts offer
protection for adults and older children, but not for
young children and infants. Neither the vehicle's
safety belt system nor its airbag system is
designed for them. Young children and infants
need the protection that a child restraint system
can provide. Always secure children properly in
your vehicle. To read how, seeOlder Children
on
page 2‑35
or Infants and Young Childrenon
page 2‑38
.
There is an airbag
readiness light on the
instrument panel cluster,
which shows the airbag
symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. See Airbag Readiness Light
on page 4‑27for
more information.

Driver Side shown, Passenger Side similar
If your vehicle has roof-rail airbags for the driver, right
front passenger, and second row outboard passengers,
they are in the ceiling above the side windows.
{WARNING:
If something is between an occupant and an
airbag, the airbag might not inflate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inflating airbag must be kept clear. Do not put
anything between an occupant and an airbag,
and do not attach or put anything on the steering
wheel hub or on or near any other airbag
covering.
Never secure anything to the roof of a vehicle with
roof-rail airbags by routing a rope or tie down
through any door or window opening. If you do,
the path of an inflating roof-rail airbag will be
blocked.

Passenger Sensing System
If the vehicle has one of the passenger airbag status
indicators pictured in the following illustrations, then the
vehicle has a passenger sensing system for the right
front passenger position. The passenger airbag status
indicator, if equipped, is visible on the instrument panel
when the vehicle is started.
In addition, if the vehicle has a passenger sensing
system for the right front passenger position, the label
on the vehicle's sun visors refer to“ADVANCED
AIRBAGS”.
United StatesCanada
The words ON and OFF, or the symbol for on and off,
will be visible during the system check. If you are using
remote start, if equipped, to start the vehicle from a
distance, you may not see the system check. When the system check is complete, either the word
ON or the word OFF, or the symbol for on or off, will be
visible. See
Passenger Airbag Status Indicator
on
page 4‑28.
The passenger sensing system will turn off the right
front passenger frontal airbag under certain conditions.
The driver airbag and roof‐rail airbags are not affected
by the passenger sensing system.
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 should be enabled
(may inflate) 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.
2-70

{WARNING:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inflates. This is because the
back of the rear-facing child restraint would be
very close to the inflating airbag. A child in a
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inflates and the passenger seat is in a forward
position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that
an airbag will not deploy under some unusual
circumstance, even though the airbag is
turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is 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.If the vehicle does not have a rear seat that will
accommodate a rear‐facing child restraint, a rear‐facing
child restraint should not be installed in the vehicle,
even if the airbag is off.
The passenger sensing system is designed to turn off
the right front passenger frontal airbag if:
.The right front passenger seat is unoccupied.
.The system determines that an infant is present in
a child restraint.
.A right front passenger takes his/her weight off of
the seat for a period of time.
.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
right front passenger frontal airbag, the off indicator will
light and stay lit to remind you that the airbag is off. See
Passenger Airbag Status Indicator on page 4‑28.
2-71

If the On Indicator is Lit for a Child
Restraint
If a child restraint has been installed and the on
indicator is lit:1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets, cushions, seat covers, seat heaters,
or seat massagers.
4. Reinstall the child restraint following the directions provided by the child restraint manufacturer and
refer to Securing a Child Restraint in the Right
Front Seat Position on page 2‑56. 5. If, after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, turn the
vehicle off. Then slightly recline the vehicle
seatback and adjust the seat cushion, if adjustable,
to make sure that the vehicle seatback is not
pushing the child restraint into the seat cushion.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint. See Head Restraints
on
page 2‑2.
6. Restart the vehicle. The passenger sensing system may or may not
turn off the airbag for a child in a child restraint
depending upon the child's seating posture and
body build. It is better to secure the child restraint
in a rear seat.
If no rear seat is available, do not install a child
restraint in this vehicle.
