for each time the vehicle is
started.
For some fleet vehicles, the
feature is always ON and
cannot be turned OFF in the
infotainment system. The
vehicle will be delayed from
shifting from P (Park) each
time the driver attempts to do
so while the driver seat belt is
not buckled. Turning the

change this condition.
On some models, Buckle to
Drive may also delay shifting
out of P (Park) if a front
passenger seat belt is
unbuckled. 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

Lap-Shoulder Belt
All seating positions in the
vehicle have a
lap-shoulder belt.
If you are using a rear seating
position with a detachable
seat belt and the seat belt is
not attached, see Rear Seats
047 for instructions on
reconnecting the seat belt to
the mini-buckle.
The following instructions
explain how to wear a
lap-shoulder belt properly.
1. If the seat has a seat belt guide, the seat belt must
be routed through the
guide to properly position
the shoulder belt. If the
seat belt is not routed
through the guide, slide
the edge of the belt
webbing through the
opening on the guide. Be
sure the belt is not twisted. 2. Adjust the seat, if the seat
is adjustable, so you can sit
up straight. To see how,
see “Seats” in the Index.
3. Pick up the latch plate and
pull the belt across you. Do
not let it get twisted.
The lap-shoulder belt may
lock if you pull the belt
across you very quickly.
If this happens, let the belt
go back slightly to unlock
it. Then pull the belt across
you more slowly. If the shoulder portion of a
passenger belt is pulled
out all the way, the child
restraint locking feature
may be engaged. See Child
Restraint Systems
077.
If this occurs, let the belt
go back all the way and
start again. If the locking
feature stays engaged
after letting the belt go
back to stowed position on
the seat, move the seat
rearward or recline the
seat until the shoulder belt
retractor lock releases.
Engaging the child
restraint locking feature in
the front outboard seating
position may affect the
passenger sensing system.
See Passenger Sensing
System 066.
If the shoulder portion of
the driver belt is pulled out
all the way, the shoulder
belt retractor lock feature
may be engaged. If this
happens, let the belt go
back all the way and start

or frayed, have it replaced
immediately. If a belt is
twisted, it may be possible to
untwist by reversing the latch
plate on the webbing. If the
twist cannot be corrected, ask
your dealer to fix it.
Make sure the seat belt
reminder light is working. See
Seat Belt Reminders0115.
Keep seat belts clean and dry.
See Seat Belt Care 058.
Seat Belt Care
Keep belts clean and dry.
Seat belts should be properly
cared for and maintained.
Seat belt hardware should be
kept dry and free of dust or
debris. As necessary, exterior
hard surfaces and seat belt
webbing may be lightly
cleaned with mild soap and
water. Ensure there is not
excessive dust or debris in the
mechanism. If dust or debris
exists in the system please
see the dealer. Parts may need to be replaced to ensure
proper functionality of the
system.
{Warning
Do not bleach or dye seat
belt webbing. It may severely
weaken the webbing. In a
crash, they might not be
able to provide adequate
protection. Clean and rinse
seat belt webbing only with
mild soap and lukewarm
water. Allow the webbing
to dry.
Replacing Seat Belt
System Parts after a
Crash
{Warning
A crash can damage the
seat belt system in the
vehicle. A damaged seat belt
system may not properly
protect the person using it,
(Continued)
Warning (Continued)
resulting in serious injury or
even death in a crash. To
help make sure the seat belt
systems are working
properly after a crash, have
them inspected and any
necessary replacements
made as soon as possible.
After a minor crash,
replacement of seat belts may
not be necessary. But the seat
belt assemblies that were
used during any crash may
have been stressed or
damaged. See your dealer to
have the seat belt assemblies
inspected or replaced.
New parts and repairs may be
necessary even if the seat belt
system was not being used at
the time of the crash.
Have the seat belt
pretensioners checked if the
vehicle has been in a crash,
or if the airbag readiness light

Airbag System
The vehicle has the following
airbags:
.A frontal airbag for the
driver
.A frontal airbag for the front
outboard passenger
.A knee airbag for the driver.
.A knee airbag for the front
outboard passenger.
.A seat-mounted side impact
airbag for the driver
.A seat-mounted side impact
airbag for the front outboard
passenger
.A roof-rail airbag for the
driver and the passenger
seated directly behind the
driver
.A roof-rail airbag for the
front outboard passenger
and the passenger seated
directly behind the front
outboard passenger All vehicle airbags have the
word AIRBAG on the trim or
on a label near the deployment
opening.
For frontal airbags, the word
AIRBAG is on the center of the
steering wheel for the driver
and on the instrument panel
for the front outboard
passenger.
For knee airbags, the word
AIRBAG is on the lower part of
the instrument panel.
For seat-mounted side impact
airbags, the word AIRBAG is
on the side of the seatback or
side of the seat closest to
the door.
For roof-rail airbags, the word
AIRBAG is on the ceiling
or trim.
Airbags are designed to
supplement the protection
provided by seat belts. Even
though today's airbags are
also designed to help reduce
the risk of injury from the
force of an inflating bag, all
airbags must inflate very
quickly to do their job.
Here are the most important
things to know about the
airbag system:
{Warning
You can be severely injured
or killed in a crash if you are
not wearing your seat belt,
even with airbags. Airbags
are designed to work with
seat belts, not replace them.
Also, airbags are not
designed to inflate in every
crash. In some crashes seat
belts are the only restraint.
See When Should an Airbag
Inflate?
062.
Wearing your seat belt
during a crash helps reduce
your chance of hitting things
inside the vehicle or being
ejected from it. Airbags are
“supplemental restraints” to
the seat belts. Everyone in

Warning (Continued)
the vehicle should wear a
seat belt properly, whether
or not there is an airbag for
that person.
{Warning
Because airbags inflate with
great force and faster than
the blink of an eye, anyone
who is up against, or very
close to, any airbag when it
inflates can be seriously
injured or killed. Do not sit
unnecessarily close to any
airbag, as you would be if
sitting on the edge of the
seat or leaning forward.
Seat belts help keep you in
position before and during a
crash. Always wear a seat
belt, even with airbags. The
driver should sit as far back
as possible while still
maintaining control of the(Continued)
Warning (Continued)
vehicle. The seat belts and
the front outboard
passenger airbags are most
effective when you are
sitting well back and upright
in the seat with both feet on
the floor.
Occupants should not lean
on or sleep against the door
or side windows in seating
positions with seat-mounted
side impact airbags and/or
roof-rail airbags.
{Warning
Children who are up against,
or very close to, any airbag
when it inflates can be
seriously injured or killed.
Always secure children
properly in the vehicle.(Continued)
Warning (Continued)
To read how, see Older
Children072 or
Infants and Young Children

There is an airbag readiness
light on the instrument cluster,
which shows the airbag
symbol.
The system checks the airbag
electrical system for
malfunctions. The light tells
you if there is an electrical
problem. See Airbag
Readiness Light 0116.

Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position.
The passenger airbag status
indicator will light on the
overhead console when the
vehicle is started.
The words ON and OFF, and
the symbols for on and off, will
be visible during the system
check. When the system check
is complete, either the word
ON or OFF, and the symbol for
on or off, will be visible. See
Passenger Airbag Status
Indicator0117.
The passenger sensing
system turns off the front
outboard passenger frontal
airbag and knee airbag under certain conditions. No other
airbag is affected by the
passenger sensing system.
The passenger sensing
system works with sensors
that are part of the front
outboard passenger seat and
seat belt. The sensors are
designed to detect the
presence of a properly seated
occupant and determine if the
front outboard passenger
frontal airbag and knee airbag
should be allowed to inflate
or not.
According to accident
statistics, children are safer
when properly secured in a
rear seat in the correct child
restraint for their weight
and size.
Whenever possible, children
aged 12 and under should be
secured in a rear seating
position.
Never put a rear-facing child
seat in the front. This is
because the risk to the
rear-facing child is so great,
if the airbag inflates.
{Warning
A child in a rear-facing child
restraint can be seriously
injured or killed if the
passenger frontal airbag
inflates. This is because the
back of the rear-facing child
restraint would be very
close to the inflating airbag.
A child in a forward-facing
child restraint can be
seriously injured or killed if
the passenger frontal airbag
inflates and the passenger
seat is in a forward position.
Even if the passenger
sensing system has turned
off the front outboard
passenger airbag(s), no
system is fail-safe. No one
can guarantee that an

Warning (Continued)
airbag will not deploy under
some unusual circumstance,
even though the airbag(s)
are off.
Never put a rear-facing child
restraint in the front seat,
even if the airbag is off.
If securing a forward-facing
child restraint in the front
outboard passenger seat,
always move the seat as far
back as it will go. It is better
to secure child restraints in
the rear seat. Consider
using another vehicle to
transport the child when a
rear seat is not available.
The passenger sensing
system is designed to turn off
the front outboard passenger
frontal airbag and knee
airbag if:
.The front outboard
passenger seat is
unoccupied.
.The system determines an
infant is present in a child
restraint.
.A front outboard passenger
takes his/her weight off of
the seat for a period of time.
When the passenger sensing
system has turned off the
front outboard passenger
frontal airbag and knee airbag,
the OFF indicator will light and
stay lit as a reminder that the
airbags are off. See Passenger
Airbag Status Indicator 0117.
The passenger sensing
system is designed to turn on
the front outboard passenger
frontal airbag and knee airbag,
anytime the system senses
that a person of adult size is
sitting properly in the front
outboard passenger seat.
When the passenger sensing
system has allowed the
airbags to be enabled, the ON
indicator will light and stay lit
as a reminder that the airbags
are active. For some children, including
children in child restraints, and
for very small adults, the
passenger sensing system
may or may not turn off the
front outboard passenger
frontal airbag and knee airbag,
depending upon the person's
seating posture and body
build. Everyone in the vehicle
who has outgrown child
restraints should wear a seat
belt properly
—whether or not
there is an airbag for that
person.
{Warning
If the airbag readiness light
ever comes on and stays on,
it means that something may
be wrong with the airbag
system. To help avoid injury
to yourself or others, have
the vehicle serviced right
away. See Airbag Readiness
Light 0116 for more
information, including
important safety
information.
