Seats and Restraints 3-45
How Does an Airbag
Restrain?
In moderate to severe frontal or
near frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact
the inside of the vehicle.
Airbags supplement the protection
provided by safety belts. Frontal
airbags distribute the force of the
impact more evenly over the
occupant's upper body, stopping
the occupant more gradually.
Seat‐mounted side impact and
roof-rail airbags distribute the force
of the impact more evenly over the
occupant's upper body.Rollover capable roof-rail airbags
are designed to help contain the
head and chest of occupants in
the outboard seating positions in
the first, second, and third rows,
if equipped with a third row seat.
The rollover capable roof-rail
airbags are designed to help
reduce the risk of full or partial
ejection in rollover events, although
no system can prevent all such
ejections.
But airbags would not help in
many types of collisions, primarily
because the occupant's motion is
not toward those airbags. See
When
Should an Airbag Inflate? on
page 3‑43 for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See After
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated.
Roof-rail airbags may still be at
least partially inflated for some
time after they deploy. Some
components of the airbag module
may be hot for several minutes. For
location of the airbag modules, see
What Makes an Airbag Inflate? on
page 3‑44.
The parts of the airbag that come
into contact with you may be
warm, but not too hot to touch.

3-46 Seats and Restraints
There may be some smoke and
dust coming from the vents in the
deflated airbags. Airbag inflation
does not prevent the driver from
seeing out of the windshield or
being able to steer the vehicle, nor
does it prevent people from leaving
the vehicle.
{WARNING
When an airbag inflates, there
may be dust in the air. This dust
could cause breathing problems
for people with a history of
asthma or other breathing trouble.
To avoid this, everyone in the
vehicle should get out as soon
as it is safe to do so. If you have
breathing problems but cannot
get out of the vehicle after an
airbag inflates, then get fresh air
by opening a window or a door.
If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.The vehicle may have a feature
that may automatically unlock the
doors, turn on the interior lamps and
hazard warning flashers, and shut
off the fuel system after the airbags
inflate. You can lock the doors, turn
off the interior lamps and hazard
warning flashers by using the
controls for those features.{WARNING
A crash severe enough to
inflate the airbags may have also
damaged important functions
in the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage
may also occur from the right front
passenger airbag.
.Airbags are designed to inflate
only once. After an airbag
inflates, you will need some
new parts for the 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.
.The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See
Vehicle Data
Recording and Privacy on
page 13‑14 andEvent Data
Recorders on page 13‑15.

Voltmeter Gauge
When the engine is not running, but
the ignition is on, this gauge shows
the battery's state of charge in
DC volts. When the engine is running, the
gauge shows the condition of the
charging system. The charging
system regulates voltage based on
the state of the battery for improved
fuel economy and battery life.
The gauge may transition from a
higher to lower or a lower to higher
reading, this is normal. Readings
between the low and high warning
zones indicate the normal operating
range. The gauge may also read
low during the fuel economy mode,
this is normal.
Readings in the low warning zone
may occur when a large number of
electrical accessories are operating
in the vehicle and the engine is left
at an idle for an extended period.
This condition is normal since the
charging system is not able to
provide full power at engine idle.
As engine speeds are increased,
this condition should correct itself
as higher engine speeds allow
the charging system to create full
power. If there is a problem with
the battery charging system, thislight will come on or the SERVICE
BATTERY CHARGING SYSTEM
DIC message will display. See
Battery Voltage and Charging
Messages on page 5‑38
and
Charging System Light on
page 5‑20 for more information.
Safety Belt Reminders
Driver Safety Belt Reminder
Light
When the engine is started, a
chime sounds for several seconds
to remind a driver to fasten the
safety belt, unless the driver safety
belt is already buckled.
The safety belt light comes on and
stays on for several seconds, then
flashes for several more.
