properly.
If your vehicle has rear head restraints
that fold down, always return them to
the full upright position whenever an
occupant is seated in the seat.

Reclining Seatbacks
{Warning
Sitting in a reclined position when the
vehicle is in motion can be dangerous.
Even when buckled up, the seat belts
cannot do their job.
The shoulder belt will not be against
your body. Instead, it will be in front of
you. In a crash, you could go into it,
receiving neck or other injuries.
The lap belt could go up over your
abdomen. The belt forces would be there,
not at your pelvic bones. This could cause
serious internal injuries.
For proper protection when the vehicle is
in motion, have the seatback upright.
Then sit well back in the seat and wear
the seat belt properly.

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 >

46 Seats and Restraints
When riding in a vehicle, you travel as fast
as the vehicle does. If the vehicle stops
suddenly, you keep going until something
stops you. It could be the windshield, the
instrument panel, or the seat belts!
When you wear a seat belt, you and the
vehicle slow down together. There is more
time to stop because you stop over a longer
distance and, when worn properly, your
strongest bones take the forces from the
seat belts. That is why wearing seat belts
makes such good sense.
Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle after acrash if I am wearing a seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your chance
of being conscious during and after a
crash, so you canunbuckle and get out,
is much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems only.
They work withseat belts —not instead
of them. Whether or not an airbag is
provided, all occupants still have to
buckle up to get the most protection. Also, in nearly all states and in all
Canadian provinces, the law requires
wearing seat belts.
Buckle To Drive
If equipped, this feature delays the vehicle
from being shifted out of P (Park) when
Teen Driver is active, and the driver seat
belt is not buckled. See
Teen Driver0163.
If the vehicle is on and the brake pedal is
pressed with the vehicle in P (Park) but the
driver seat belt is not buckled, a message
displays in the Driver Information
Center (DIC) and the vehicle will be delayed
from shifting out of P (Park). Buckle the
driver seat belt to clear the message and
shift out of P (Park). Shifting from P (Park)
will be delayed once for each time the
vehicle is started.
For some fleet vehicles, shifting out of
P (Park) will be delayed each time the driver
attempts to do so while the driver seat belt
is not buckled, whether Teen Driver is ON or
OFF. Turning the vehicle off then on will not
change this condition.
On some models, Buckle to Drive may also
delay shifting out of P (Park) if a front
passenger is unbuckled under similar
conditions. A message displays in the DIC. Buckle the front passenger seat belt to shift
out of P (Park). This feature may delay the
vehicle from shifting out of P (Park) if an
object, such as a briefcase, handbag, grocery
bag, laptop, or other electronic device, is on
the front passenger seat. If this happens,
remove the object from the seat or buckle
the seat belt to shift out of P (Park).
If the driver, or on some vehicles, the
present front passenger seat belt remains
unbuckled, the DIC message will turn off
after several seconds and the vehicle can be
shifted out of P (Park). See
“Seat Belts”and
“Child Restraints” in the Index for
information about the importance of proper
restraint use.
If the driver seat belt or the front passenger
seat belt is unbuckled when driving, the seat
belt reminder chime and light(s) will come
on. See Seat Belt Reminders 099. This
feature may not function properly if the
airbag readiness light is on. See Airbag
Readiness Light 099.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
