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.

Rear Seats
Rear Seat Reminder
If equipped, the message
REAR SEAT REMINDER LOOK
IN REAR SEAT displays under
certain conditions indicating
there may be an item or
passenger in the rear seat.
Check before exiting the
vehicle. This feature will activate when
a second row door is opened
while the vehicle is on or up to
10 minutes before the vehicle
is turned on. There will be an
alert when the vehicle is
turned off. The alert does not
directly detect objects in the
rear seat; instead, under
certain conditions, it detects
when a rear door is opened
and closed, indicating that
there may be something in the
rear seat.
The feature is active only once
each time the vehicle is turned
on and off, and will require
reactivation by opening and
closing the second row doors.
There may be an alert even
when there is nothing in the
rear seat; for example, if a
child entered the vehicle
through the rear door and left
the vehicle without the vehicle
being shut off.
The feature can be turned on
or off. Select Settings >
Vehicle > Rear Seat
Reminder > ON or OFF.
Folding the Seatback
Either side of the seatback
can be folded for more cargo
space. Fold a seatback only
when the vehicle is not
moving.
Caution
Folding a rear seat with the
seat belts still fastened may
cause damage to the seat or
the seat belts. Always
unbuckle the seat belts and
return them to their normal
stowed position before
folding a rear seat.

56 Seats and Restraints
To unlatch the belt, push the
button on the buckle. The belt
should return to its stowed
position.
Slide the adjustable stop along
the webbing toward the guide
loop when the seat belt is not
in use to prevent the latch
plate from rattling against the
interior trim.
Always stow the seat belt
slowly. If the seat belt webbing
returns quickly to the stowed
position, the retractor may
lock and cannot be pulled out.
If this happens, pull the seat
belt straight out firmly tounlock the webbing, and then
release it. If the webbing is still
locked in the retractor, see
your dealer.
Before a door is closed, be
sure the seat belt is out of the
way. If a door is slammed
against a seat belt, damage
can occur to both the seat
belt and the vehicle.
Seat Belt Pretensioners
This vehicle has seat belt
pretensioners for the front
outboard occupants. Although
the seat belt pretensioners
cannot be seen, they are part
of the seat belt assembly.
They can help tighten the seat
belts during the early stages
of a moderate to severe
frontal, near frontal, or rear
crash if the threshold
conditions for pretensioner
activation are met. Seat belt
pretensioners can also help
tighten the seat belts in a side
crash or a rollover event.
Pretensioners work only once.
If the pretensioners activate in
a crash, the pretensioners and
probably other parts of the
vehicle's seat belt system will
need to be replaced. See
Replacing Seat Belt System
Parts after a Crash
058.
Do not sit on the outboard
seat belt while entering or
exiting the vehicle or at any
time while sitting in the seat.
Sitting on the seat belt can
damage the webbing and
hardware.
Rear Seat Belt Comfort
Guides
Rear seat belt comfort guides
may provide added seat belt
comfort for older children who
have outgrown booster seats
and for some adults. When
installed on a shoulder belt,
the comfort guide positions
the shoulder belt away from
the neck and head.

62 Seats and Restraints
Driver Side Shown,
Passenger Side Similar
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.

Warning (Continued)
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.
