{Warning
Never leave a child, a helpless adult,
or a pet alone in a vehicle,
especially with the windows closed
in warm or hot weather. They can
be overcome by the extreme heat
and suffer permanent injuries or
even death from heat stroke.
The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear window is down and the front
windows are up. To reduce the sound,
open either a front window or the
sunroof, if equipped.

{Warning
Children could be seriously injured
or killed if caught in the path of a
closing window. Never leave the

90 SEATS AND RESTRAINTS
{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 has 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. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
You can lock the doors, turn off the interior lamps, and turn off the 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.
PLUG-IN vehicles have a high voltage
battery and a standard 12-volt battery.
If an airbag inflates or the vehicle has
been in a crash, the vehicle's sensing
system may shut down the high
voltage system. When this occurs, the
high voltage battery is disconnected
and the vehicle is not charging the
12-volt battery or the electrical system. The vehicle may start but it
shuts down once the 12-volt battery is
depleted. The airbag readiness light
and/or the 12-volt battery warning
light are displayed. Before the vehicle
can be operated again, it must be
serviced at your dealer.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
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 the vehicle covers the
need to replace other parts.
