50 SEATS AND RESTRAINTS
Heated Rear Seats
{Warning
If temperature change or pain to
the skin cannot be felt, the seat
heater may cause burns. See the
Warning underHeated and
Ventilated Front Seats 045.
If available, the buttons are on the
rear of the center console.
With the engine running, press
Mor
Lto heat the left or right outboard
seat cushion. An indicator on the
climate control display appears when
this feature is on. This feature turns on at the highest
setting. With each press of the button,
the heated seat changes to the next
lower setting, and then the off setting.
Three lights indicate the highest
setting, and one light indicates the
lowest. If the heated seats are on high,
the level may automatically be
lowered after approximately
30 minutes.
Third Row Seats
{Warning
Using the third row seating position
while the second row is folded,
or pushed forward in the entry
position, could cause injury in a
sudden stop or crash. Be sure to
return the seat to the passenger
seating position. Push and pull on
the seat to make sure it is locked
into place.
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.
Folding the Seatback
1. Remove objects on the floor in
front of or on the second row seat,
or in the seat tracks on the floor.
2. If the second row seat is in the full rear position, adjust it forward to
allow the third row seat to fold
fully flat.

56 SEATS AND RESTRAINTS
Never route the lap or shoulder belt
over an armrest.
{Warning
The seat belt can be pinched if it is
routed under plastic trim on the
seat, such as trim around the rear
seatback folding handle or side
airbag. In a crash, pinched seat
belts might not be able to provide
adequate protection. Never allow
seat belts to be routed under plastic
trim pieces.
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
The following instructions explain
how to wear a lap-shoulder belt
properly.1. Adjust the seat, if the seat is adjustable, so you can sit up
straight. To see how, see “Seats”in
the Index.
2. 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 076. 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.

60 SEATS AND RESTRAINTS
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,
frayed, or twisted seat belts may not
protect you in a crash. Torn or frayed
seat belts can rip apart under impact
forces. If a belt is torn or frayed, haveit 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 Reminders
0 113.
Keep seat belts clean and dry. See Seat
Belt Care 060.
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,
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.

SEATS AND RESTRAINTS 61
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
stays on after you start the vehicle or
while you are driving. SeeAirbag
Readiness Light 0114.
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 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
for the second and third row
passengers seated directly behind
the driver
.A roof-rail airbag for the front
outboard passenger and for the
second and third row passengers
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? 064.
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 (Continued)
