1-10 Seats and Restraint System

First, before you or your
passenger(s) wear a safety belt,
there is important information
you should know.
Sit up straight and always keep your
feet on the oor in front of you. The
lap part of the belt should be worn
low and snug on the hips, justtouching the thighs. In a crash, this
applies force to the strong pelvic
bones and you would be less likely to
slide under the lap belt. If you slid
under it, the belt would apply force
on your abdomen. This could
cause serious or even fatal injuries.
The shoulder belt should go over
the shoulder and across the chest.
These parts of the body are best able
to take belt restraining forces.
The shoulder belt locks if there is a
sudden stop or crash.Q:What is wrong with this?
A:The shoulder belt is too loose.
It will not give as much
protection this way.
{CAUTION
You can be seriously hurt if your
shoulder belt is too loose. In a
crash, you would move forward
too much, which could increase
injury. The shoulder belt should t
snugly against your body.

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

Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger seating
positions.
Adjust the height so that the shoulder
portion of the belt is centered on the
shoulder. The belt should be away
from the face and neck, but not
falling off of the shoulder. Improper
shoulder belt height adjustment
could reduce the effectiveness of the
safety belt in a crash.
To move it down, press the release
button (A) and move the height
adjuster to the desired position.
You can move the height adjuster up
just by pushing up on the shoulder
belt guide.
After the adjuster is set to the desired
position, try to move it down without
pushing the button to make sure it
has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for the front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety belts
during the early stages of a moderate
to severe frontal, near frontal, or rear
crash if the threshold conditions for
pretensioner activation are met. And,
for vehicles with side impact airbags,
safety belt pretensioners can help
tighten the safety belts in a side
crash or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash,
they will need to be replaced, and
probably other new parts for the
vehicle’s safety belt system. See
Replacing Restraint System Parts
After a Crash on page 1-60.

{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

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.
