48 Seats and Restraints Active Head Restraints Your vehicle has an Active Head
Restraint System in the front
outboard seating positions. These
automatically activate to reduce the
risk of neck injury if the vehicle is hit
from behind.

activated due to a rear collision,
you must return the vehicle to the
dealer for inspection and
re-setting or replacement of the
system. Rear Seats The vehicle ’ s rear seats have
non-adjustable head restraints in the
outboard seating positions.
The rear head restraints are
designed to be removed. See

56 Seats and Restraints Pull up on the latch plate to
make sure it is secure. If the
belt is not long enough, see
Seat Belt Extender 0 58 .
Position the release button on
the buckle so that the seat belt
could be quickly unbuckled if
necessary.
4. To make the lap part tight, pull
up on the shoulder belt. To unlatch the belt, push the button
on the buckle. The belt should
return to its stowed position.
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 to unlock
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 Presenter The seat belt presenters bring the
front outboard seat belts to the front
to help fasten them.
The presenter comes out when:
.
The respective door is closed
and the ignition is turned on.
.
The ignition is on and the door is
closed.
The presenter may automatically
retract when any of the following
occur:
.
The respective door is opened
again.

58 Seats and Restraints that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making seat
belts effective is wearing them
properly.
Seat Belt Extender If the vehicle's seat belt will fasten
around you, you should use it.
But if a seat belt is not long enough,
your dealer will order you an
extender. When you go in to order it,
take the heaviest coat you will wear,
so the extender will be long enough
for you. To help avoid personal
injury, do not let someone else use
it, and use it only for the seat it is
made to fit. The extender has been
designed for adults. Never use it for
securing child restraints. For more
information on the proper use and fit
of seat belt extenders see the
instruction sheet that comes with
the extender. Safety System Check Periodically check the seat belt
reminder, seat belts, buckles, latch
plates, retractors, shoulder belt
height adjusters (if equipped), and
seat belt anchorages to make sure
they are all in working order. Look
for any other loose or damaged seat
belt system parts that might keep a
seat belt system from performing
properly. See your dealer to have it
repaired. Torn or frayed seat belts
may not protect you in a crash.
They can rip apart under impact
forces. If a belt is torn or frayed,
have it replaced immediately.
Make sure the seat belt reminder
light is working. See Seat Belt
Reminders 0 100 .
Keep seat belts clean and dry. See
Seat Belt Care 0 58 .
Seat Belt Care Keep belts clean and dry. { WarningDo 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.
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.

60 Seats and Restraints For seat-mounted side impact
airbags, the word AIRBAG is on the
side of the seatback closest to
the door.
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:
{ WarningYou 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? 0 62 .
(Continued) Warning (Continued) 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 the
vehicle should wear a seat belt
properly, whether or not there is
an airbag for that person.
{ WarningBecause 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
(Continued) Warning (Continued) crash. Always wear the seat belt,
even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the 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 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. To read
how, see Older Children 0 71 or
Infants and Young Children 0 72 .

Seats and Restraints 65designed to deploy in moderate to
severe side crashes depending on
the location of the impact, as well as
in a severe frontal impact. Roll bars
are not designed to deploy in rear
impacts.
The roll bars deploy with the
convertible top open or closed. If the
roll bars deploy, do not operate the
convertible top.
Do not place any objects on the
covers of the roll bars behind the
head restraints.
Have the roll bars checked if the
vehicle has been in a crash, or if the
airbag readiness light stays on after
starting or driving the vehicle. See
Airbag Readiness Light 0 101 .
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 center stack when
the vehicle is started. The words ON and OFF will be
visible during the system check.
When the system check is
complete, either the word ON or the
word OFF will be visible. See
Passenger Airbag Status Indicator
0 101 .
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.
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.
{ WarningA 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.
