iv Preface

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, see60/40 Split Bench
Seat (H3) on page 1-7or60/40 Split
Bench Seat (H3T) on page 1-9for
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.
Engaging the child restraint
locking feature in the right front
seating position may affect
the passenger sensing system.
SeePassenger Sensing
System on page 1-54for
more information.
1-20 Seats and Restraint System

{CAUTION
Do not attach more than one child
restraint to a single anchor.
Attaching more than one child
restraint to a single anchor could
cause the anchor or attachment to
come loose or even break during
a crash. A child or others could
be injured. To reduce the risk of
serious or fatal injuries during a
crash, attach only one child
restraint per anchor.
{CAUTION
Children can be seriously injured
or strangled if a shoulder belt is
wrapped around their neck and
the safety belt continues to
tighten. Buckle any unused safety
(Continued)
CAUTION (Continued)
belts behind the child restraint so
children cannot reach them. Pull
the shoulder belt all the way out
of the retractor to set the lock, if
your vehicle has one, after the
child restraint has been installed.
Notice:Do not let the LATCH
attachments rub against the
vehicle’s safety belts. This may
damage these parts. If necessary,
move buckled safety belts to avoid
rubbing the LATCH attachments.
Do not fold the empty rear seat
with a safety belt buckled. This
could damage the safety belt or
the seat. Unbuckle and return the
safety belt to its stowed position,
before folding the seat.
H3T Models

recommends that the top tether
be attached, attach and tightenthe top tether to the top tether
anchor (A), if equipped. Refer to
the child restraint instructions and
the following steps:
1.1. Put the child restraint on
the seat.
1.2. Pull the seatback forward
to access the top tether
anchors (A). See60/40 Split

If the position you are using
has a xed headrest or
head restraint and you are
using a dual tether,
route the tether around the
headrest or head restraint.
1.4. Attach the top tether to the
anchor (A). Make sure that
you secure the top tether to
the top tether anchor and not
to the seatback latch (B).
1.5. Push rearward on the
seatback until it locks
into its upright position.
Push and pull on the
seatback to make sure it is
secured properly.2. Attach and tighten the lower
attachments to the lower
anchors. If the child restraint
does not have lower attachments
or the desired seating position
does not have lower anchors,
secure the child restraint with the
top tether and the safety belts.
Refer to the child restraint
manufacturer instructions and the
instructions in this manual.
2.1. Find the lower anchors for
the desired seating position.
2.2. Attach and tighten the
lower attachments on
the child restraint to the
lower anchors.
3. Tighten the top tether. If the
headrest interferes with the
installation of the child restraint,
remove the headrest by
pressing the button on the
headrest post, at the top of the
seatback and lift to remove. Store
the headrest under the outboard
side of the rear seat.4. Push and pull the child restraint
in different directions to be sure
it is secure. When removing
the child restraint, reinsert
the headrest if it has been
removed from the seatback.

attachments to the lower
anchors. If the child restraint
does not have lower attachments
or the desired seating position
does not have lower anchors,

the top tether and the safety
belts. Refer to the child restraint
manufacturer instructions and
the instructions in this manual.
1.1. Find the lower anchors
for the desired seating
position.

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.5. For H3 models, pull the rest of the
shoulder belt all the way out of the
retractor to set the lock.6. To tighten the belt, push down on
the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint, it
may be helpful to use your knee
to push down on the child
restraint as you tighten the belt.
1-42 Seats and Restraint System

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, the off indicator on the
passenger airbag status indicator
should light and stay lit when
the vehicle is started. See
Passenger Airbag Status
Indicator on page 3-26.
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.5. Pull the rest of the shoulder belt
all the way out of the retractor to
set the lock.
Seats and Restraint System 1-45

If the Off Indicator is Lit for an
Adult-Size Occupant
If a person of adult-size is sitting in
the right front passenger seat, but
the off indicator is lit, it could be
because that person is not sitting
properly in the seat. If this happens,
use the following steps to allow thesystem to detect that person and
enable the right front passenger
frontal airbag and seat-mounted side
impact airbag (if equipped):
1. Turn the vehicle off.
2. Remove any additional material
from the seat, such as blankets,
cushions, seat covers, seat
heaters, or seat massagers.
3. Place the seatback in the fully
upright position.
4. Have the person sit upright in
the seat, centered on the seat
cushion, with legs comfortably
extended.
5. Restart the vehicle and have the
person remain in this position for
two to three minutes after the
on indicator is lit.
Additional Factors Affecting
System Operation
Safety belts help keep the passenger
in position on the seat during vehicle
maneuvers and braking, which helps
the passenger sensing system
maintain the passenger airbag
status. See “Safety Belts” and “Child
Restraints” in the Index for additional
information about the importance of
proper restraint use.
If the shoulder portion of the belt is
pulled out all the way, the child
restraint locking feature will be
engaged. This may unintentionally
cause the passenger sensing system
to turn the airbag(s) off for some
adult size occupants. If this happens,
just let the belt go back all the way
and start again.
