The roof-rail airbags for the
driver, front outboard
passenger, and second row
outboard passengers 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 (Continued)
Warning (Continued)
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.
Do not use seat accessories
that block the inflation path
of a seat-mounted side
impact airbag.
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.
When Should an
Airbag Inflate?
This vehicle is equipped with
airbags. See Airbag System
059. Airbags are designed to
inflate if the impact exceeds
the specific airbag system's
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. The
vehicle has electronic sensors
that help the airbag system
determine the severity of the
impact. Deployment
thresholds can vary with
specific vehicle design.
Frontal airbags are designed
to inflate in moderate to
severe frontal crashes to help
reduce the potential for
severe injuries, mainly to the
driver's or front outboard
passenger's head and chest.

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. After turning the
ignition off and then on again,
the fuel system will return to
normal operation; the doors
can be locked, the interior
lamps can be turned off, and
the hazard warning flashers
can be turned off using the
controls for those features.
If any of these systems are
damaged in the crash they
may not operate as normal.
{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 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.
.The vehicle has a crash
sensing and diagnostic
module which records
information after a crash.
See Vehicle Data Recording
and Privacy
0496 and
Event Data Recorders 0497.
.Let only qualified technicians
work on the airbag system.
Improper service can mean
that an airbag system will
not work properly. See your
dealer for service.

Battery Load
Management
The vehicle has Electric Power
Management (EPM), which
estimates the battery's
temperature and state of
charge. It then adjusts the
voltage for best performance
and extended life of the
battery.
When the battery's state of
charge is low, the voltage is
raised slightly to quickly bring
the charge back up. When thestate of charge is high, the
voltage is lowered slightly to
prevent overcharging. If the
vehicle has a voltmeter gauge
or a voltage display on the
Driver Information Center
(DIC), you may see the voltage
move up or down. This is
normal. If there is a problem,
an alert will be displayed.
The battery can be discharged
at idle if the electrical loads
are very high. This is true for
all vehicles. This is because
the generator (alternator) may
not be spinning fast enough at
idle to produce all the power
that is needed for very high
electrical loads.
A high electrical load occurs
when several of the following
are on, such as: headlamps,
high beams, fog lamps, rear
window defogger, climate
control fan at high speed,
heated seats, engine cooling
fans, and loads plugged into
accessory power outlets.
EPM works to prevent
excessive discharge of the
battery. It does this by
balancing the generator's
output and the vehicle's
electrical needs. It can
increase engine idle speed to
generate more power,
whenever needed. It can
temporarily reduce the power
demands of some accessories.
Normally, these actions occur
in steps or levels, without
being noticeable. In rare cases
at the highest levels of
corrective action, this action
may be noticeable to the
driver. If so, a DIC message
might be displayed. If a battery
message is displayed, it is
recommended that the driver
reduce the electrical loads as
much as possible. See Driver
Information Center (DIC) (Base
Level)
0129 or
Driver Information Center
(DIC) (Uplevel) 0132.
