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

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.
