When Should an Airbag Inflate?
Frontal airbags are designed to inflate in moderate to
severe frontal or near-frontal crashes to help reduce the
potential for severe injuries mainly to the driver's or right
front passenger's head and chest. However, they are
only designed to inflate if the impact exceeds a
predetermined deployment threshold. Deployment
thresholds are used to predict how severe a crash is
likely to be in time for the airbags to inflate and help
restrain the occupants.
Whether your frontal airbags will or should deploy is not
based on how fast your vehicle is traveling. It depends
largely on what you hit, the direction of the impact, and
how quickly your vehicle slows down.
Frontal airbags may inflate at different crash speeds.
For example:
.If the vehicle hits a stationary object, the airbags
could inflate at a different crash speed than if the
vehicle hits a moving object.
.If the vehicle hits an object that deforms, the
airbags could inflate at a different crash speed
than if the vehicle hits an object does not deform.
.If the vehicle hits a narrow object (like a pole), the
airbags could inflate 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 inflate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specific vehicle design.
Frontal airbags are not intended to inflate during vehicle
rollovers, rear impacts, or in many side impacts.
In addition, your vehicle has dual-stage frontal airbags.
Dual-stage airbags adjust the restraint according to
crash severity. Your vehicle has an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more severe
frontal impact. For moderate frontal impacts, dual-stage
airbags inflate at a level less than full deployment. For
more severe frontal impacts, full deployment occurs.
Your vehicle may or may not have roof-rail airbags. See
Airbag System
on page 2‑58. Roof-rail airbags are
intended to inflate in moderate to severe side crashes.
In addition, these roof-rail airbags are intended to inflate
during a rollover. Roof-rail airbags will inflate if the crash
severity is above the system's designed threshold level.
The threshold level can vary with specific vehicle
design.
Roof-rail airbags are not intended to inflate in frontal
impacts, near-frontal impacts, or rear impacts.
A roof-rail airbag is intended to deploy on the side of the
vehicle that is struck or if the sensing system predicts
that the vehicle is about to roll over.

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 4‑27. 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.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer and the service manual
have information about servicing the vehicle and the
airbag system. To purchase a service manual, see
Service Publications Ordering Information
on
page 8‑14.
{WARNING:
For up to 10 seconds after the ignition is turned off
and the battery is disconnected, an airbag can still
inflate during improper service. You can be injured
if you are close to an airbag when it inflates. 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 qualified 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 the 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, front sensors, side impact sensors,
rollover sensor module, or airbag wiring can affect
the operation of the airbag system.
In addition, the vehicle may have a passenger
sensing system for the right front passenger
position, which includes sensors that are part of the
passenger 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,
2-72

Black plate (73,1)Chevrolet HHR Owner Manual - 2011
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 2‑66.

Different Size Tires and Wheels
on page 6‑65for
additional important information.
Q: Because I have a disability, I have to get my vehicle modified. How can I find 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 8‑2.
In addition, your dealer and the service manual have
information about the location of the airbag sensors,
sensing and diagnostic module and airbag wiring.
Restraint System Check
Checking the Restraint Systems
Safety Belts
Now and then, check that the safety belt reminder light,
safety belts, buckles, latch plates, retractors, and
anchorages are all working properly.
Look for any other loose or damaged safety belt system
parts that might keep a safety belt system from doing its
job. See your dealer to have it repaired. Torn or frayed
safety belts may not protect you in a crash. They can rip
apart under impact forces. If a belt is torn or frayed, get
a new one right away.
Make sure the safety belt reminder light is working. See
Safety Belt Reminders
on page 4‑25for more
information.
Keep safety belts clean and dry. See Care of Safety
Belts
on page 6‑95.

Wiper Activated Headlamps
The headlamps and parking lamps are activated
15 seconds after the windshield wipers are turned on.
For this feature to work, automatic lighting must be
enabled. SeeHeadlamps
on page 4‑11for additional
information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They also turn off
15 seconds after the windshield wiper control is
turned off.
Headlamps on Reminder
If the drivers door is opened with the ignition off and the
lamps on, a warning chime will sound. This indicates
that the headlamps are still on.
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 daytime running lamps are required on
all vehicles first sold in Canada. The vehicle has a light sensor on top of the instrument
panel. Do not cover this sensor or the headlamps will
come on when they are not needed.
The DRL system will make the headlamps come on at
reduced brightness when the following conditions
are met:
.The ignition is on.
.The exterior lamp control is turned to AUTO.
.The light sensor detects daytime light.
.The shift lever is not in P (Park).
While the DRL system is on, the taillamps, sidemarker
lamps, and instrument panel lights will not be on.
For vehicles with an Automatic Transmission, the
DRL system is off any time the vehicle is in P (Park).
For vehicles with a Manual Transmission, the DRL
system will be off when the vehicle is first started, the
park brake is applied, and the vehicle has not moved.
The DRL system on U.S. vehicles can also be turned
off by using the off/on switch for one ignition cycle.
The regular headlamp system should be turned on
when needed.

Automatic Headlamp System
When it is dark enough outside, the automatic system
turns on the headlamps at the normal brightness along
with other lamps such as the taillamps, sidemarker,
parking lamps, instrument panel lights, and interior
switch backlighting.
Do not cover the light sensor, located on top of the
instrument panel. If the sensor is covered the
headlamps may remain on when they are not needed.
If the vehicle is driven through a parking garage,
overcast weather or a tunnel, the automatic headlamp
system may turn on.
There is a delay in the transition between the daytime
and nighttime operation of the automatic lamp control
system so that driving under bridges or bright overhead
street lights does not affect the system. The automatic
lamp control system will only be affected when the light
sensor sees a change in lighting lasting longer than this
delay.
If the vehicle is started in a dark garage, the automatic
lamp system turns on immediately. Once the vehicle
exits the garage, it will take about 20 seconds for the
automatic lamp 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 theinstrument panel brightness control is in the full bright
position. See
Instrument Panel Brightnesson
page 4‑14.
To idle the vehicle with the system off, turn the ignition
on and turn the exterior light switch to the off/on
position. For vehicles first sold in Canada, the
transmission must stay in P (Park) for this function or
the parking brake must be set for vehicles with manual
transmissions.
Turn on the regular headlamps when they are needed.
Fog Lamps
For vehicles with fog lamps, the button is located on the
instrument panel, to the right of the steering wheel.
The ignition must be on to use the fog lamps.
#: Press to turn the fog lamps on and off. An indicator
light on the button 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 will 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.

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 2‑58.
The airbag readiness light
flashes for a few seconds
when the engine is
started. If the light does
not come on then, have it
fixed immediately.
{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also
come on. See DIC Warnings and Messages
