When Should an Airbag Inate?
Frontal airbags are designed to inate 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 inate 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 inate 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 inate at different crash speeds.
For example:
If the vehicle hits a stationary object, the airbags
could inate at a different crash speed than if the
vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate 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 inate 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 inate at a different crash speed
than if the vehicle goes straight into the object.
Thresholds can also vary with specic vehicle design.
Frontal airbags are not intended to inate 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 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.
Your vehicle may or may not have roof-rail airbags.
SeeAirbag System on page 1-56. Roof-rail airbags are
intended to inate in moderate to severe side crashes.
In addition, these roof-rail airbags are intended to inate
during a rollover. 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.

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 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’s airbag inates. This is because
the back of the rear-facing child restraint
would be very close to the inating airbag.
CAUTION: (Continued)
CAUTION: (Continued)
Even though the passenger sensing system is
designed to turn off the right front 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 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 your vehicle does not have a rear seat that will
accommodate a rear-facing child restraint, we
recommend that rear-facing child restraints not be
transported in your vehicle, even if the airbag is off.

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, rollover sensor module, or airbag
wiring can affect the operation of the airbag system.
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 theseat 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 1-64.

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 can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
Daytime Running Lamps (DRL) are required on all
vehicles rst sold in Canada.
The DRL system will make your low-beam headlamps
come on at a reduced brightness in daylight when
the following conditions are met:
The ignition is on.
The exterior lamp band is in the automatic position.
The transmission is not in PARK (P).
The light sensor determines it is daytime.
The parking brake is released.
When the DRL are on, the low-beam headlamps will be
on at a reduced brightness. The taillamps, sidemarker
and other lamps will not be on. The instrument panel will
not be lit up either.When the exterior lamp band is turned to the headlamp
position, the low-beam headlamps come on. The
other lamps that come on with the headlamps will also
come on.
When the headlamps are turned off, the regular lamps
will go off, and the low-beam headlamps come on
to the reduced brightness.
To idle your vehicle with the DRL off, move the shift
lever to PARK (P). The DRL will stay off until the shift
lever is moved out of the PARK (P) position.
The regular headlamp system should be turned on
when needed.
Automatic Headlamp System
When it is dark enough outside and the exterior lamps
control is in the automatic position, the headlamps
will come on automatically. SeeHeadlamps on
page 3-14.
Your vehicle has a light sensor located on top of the
instrument panel. Make sure it is not covered, or
the headlamps will be on when you do not need them.
The system may also turn on the headlamps when
driving through a parking garage or tunnel.

This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s belt
is already buckled, neither the chime nor the light will
come on.
Passenger Safety Belt Reminder Light
Several seconds after the engine is started, a chime will
sound for several seconds to remind the front passenger
to buckle their safety belt. This would only occur if the
passenger airbag is enabled. SeePassenger Sensing
System on page 1-64for more information. The
passenger safety belt light, located on the instrument
panel, will come on and stay on for several seconds and
then ash for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
If the passenger’s safety belt is buckled, neither the
chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument panel
cluster, which shows the airbag symbol. The system
checks the airbag’s electrical system for malfunctions.
The light tells you if 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 1-56.
