1-14 Seats and Restraint System

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 safety
belt and the safety belt is not
attached, seeThird Row Seats on
page 1-12for instruction on
reconnecting the safety belt to the
mini-buckle.
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.
If this happens, let the belt go
back all the way and start again.3. Push the latch plate into the
buckle until it clicks.
4. Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, seeSafety
Belt Extender on page 1-28.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
Seats and Restraint System 1-23

Do not secure a child seat in a
position without a top tether anchor
if a national or local law requires
that the top tether be anchored, or if
the instructions that come with
the child restraint say that the top
strap must be anchored.
In Canada, the law requires that
forward-facing child restraints have
a top tether, and that the tether
be attached.You will be using the lap-shoulder
belt to secure the child restraint
in this position. Follow the
instructions that came with
the child restraint.
1. Move the seat as far back as it
will go before securing the
forward-facing child restraint.
When the passenger sensing
system has turned off the
right front passenger frontal
airbag and seat-mounted side
impact airbag, the off indicator on
the passenger airbag status
indicator should light and stay lit
when the vehicle is started.
SeePassenger Airbag Status
Indicator on page 3-36.
2. Put the child restraint on
the seat.3. Pick up the latch plate, and run
the lap and shoulder portions of
the vehicle’s safety belt
through or around the restraint.
The child restraint instructions
will show you how.
4. Push the latch plate into the
buckle until it clicks.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
1-46 Seats and Restraint System

{CAUTION
Airbags inate with great force,
faster than the blink of an eye.
Anyone who is up against, or very
close to, any airbag when it
inates can be seriously injured or
killed. Do not sit unnecessarily
close to the airbag, as you would
be if you were sitting on the edge
of your seat or leaning forward.
Safety belts help keep you in
position before and during a
crash. Always wear your safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
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.
{CAUTION
Children who are up against, or
very close to, any airbag when it
inates can be seriously injured or
killed. Airbags plus lap-shoulder
belts offer protection for adults
and older children, but not for
young children and infants.
Neither the vehicle’s safety belt
system nor its airbag system is
designed for them. Young children
and infants need the protection
that a child restraint system can
provide. Always secure children
properly in your vehicle. To read
how, seeOlder Children on
page 1-29orInfants and Young
Children on page 1-31.There is an airbag readiness light
on the instrument panel 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. SeeAirbag
Readiness Light on page 3-36for
more information.
Seats and Restraint System 1-49

When the passenger sensing
system has turned off the right front
passenger frontal airbag, the off
indicator will light and stay lit
to remind you that the airbag is off.
SeePassenger Airbag Status
Indicator on page 3-36.
The passenger sensing system is
designed to turn on (may inate) the
right front passenger frontal airbag
anytime the system senses that a
person of adult size is sitting properly
in the right front passenger seat.
When the passenger sensing
system has allowed the airbag to be
enabled, the on indicator will light
and stay lit to remind you that
the airbag is 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
right front passenger frontal airbag,
depending upon the person’s seating
posture and body build. Everyone in
the vehicle who has outgrown childrestraints should wear a safety belt
properly —whether or not there is an
airbag for that person.
{CAUTION
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.
SeeAirbag Readiness Light on
page 3-36for more information,
including important safety
information.
If the On Indicator is Lit for a
Child Restraint
If a child restraint has been installed
and the on indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from
the vehicle.3. Remove any additional items
from the seat such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
4. Reinstall the child restraint
following the directions provided
by the child restraint
manufacturer and refer to
Securing a Child Restraint in the
Right Front Seat Position on
page 1-45.
5. If, after reinstalling the child
restraint and restarting the
vehicle, the on indicator is still lit,
turn the vehicle off. Then
slightly recline the vehicle
seatback and adjust the seat
cushion, if adjustable, to
make sure that the vehicle
seatback is not pushing the child
restraint into the seat cushion.
Also make sure the child restraint
is not trapped under the vehicle
head restraint. If this happens,
adjust the head restraint.
SeeHead Restraints on
page 1-2.
