Lap-Shoulder Belt
All seating positions in the vehicle have a lap-shoulder
belt except for the center front passenger position (if
equipped), which has a lap belt. SeeLap Belt
on
page 2‑31for more information.
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 may
affect the passenger sensing system, if equipped.
See Passenger Sensing System
on page 2‑66for
more information. If the belt stops before it reaches the buckle, for
the rear center seating position, tilt the latch plate
and keep pulling the safety belt until it can be
buckled.
3. Push the latch plate into the buckle until it clicks.
If you find that the latch plate will not go fully into
the buckle, see if you are using the correct buckle.
Pull up on the latch plate to make sure it is secure.
If the belt is not long enough, see Safety Belt
Extender
on page 2‑32.
Position the release button on the buckle so that
the safety belt could be quickly unbuckled if
necessary.

Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort
guides. If not, they are available through your dealer/
retailer. The guides may provide added safety belt
comfort for older children who have outgrown booster
seats and for some adults. When installed and properly
adjusted, the comfort guide positions the belt away from
the neck and head.Here is how to install a comfort guide to the safety belt:
1. Remove the guide from its storage pocket on the
side of the seat.
2-28

To make the belt shorter, pull its free end as shown until
the belt is snug.
If the belt is not long enough, seeSafety Belt Extender
on page 2‑32.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the safety
belt quickly if necessary.
If you find that the latch plate will not go fully into the
buckle, see if you are using the correct buckle. Be sure
that the latch plate clicks when inserted into the buckle.
Safety Belt Extender
If the vehicle's safety belt will fasten around you, you
should use it.
But if a safety belt is not long enough, your dealer/
retailer 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
seats. To wear it, attach it to the regular safety belt. For
more information, see the instruction sheet that comes
with the extender.

Child Restraints
Older Children
Older children who have outgrown booster seats should
wear the vehicle's safety belts.The manufacturer's instructions that come with the
booster seat, state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder belt
until the child passes the below fit test:
.Sit all the way back on the seat. Do the knees
bend at the seat edge? If yes, continue. If no,
return to the booster seat.
.Buckle the lap-shoulder belt. Does the shoulder
belt rest on the shoulder? If yes, continue. If no, try
using the rear safety belt comfort guide. See
“Rear
Safety Belt Comfort Guides” underLap-Shoulder
Belt
on page 2‑25for more information. If the
shoulder belt still does not rest on the shoulder,
then return to the booster seat.
.Does the lap belt fit low and snug on the hips,
touching the thighs? If yes, continue. If no, return
to the booster seat.
.Can proper safety belt fit be maintained for length
of trip? If yes, continue. If no, return to the
booster seat.
If you have the choice, a child should sit in a position
with a lap-shoulder belt and get the additional restraint
a shoulder belt can provide.
2-33

Q: What is the proper way to wear safety belts?
A:An older child should wear a lap-shoulder belt and
get the additional restraint a shoulder belt can
provide. The shoulder belt should not cross the face
or neck. The lap belt should fit snugly below the
hips, just touching the top of the thighs. This applies
belt force to the child's pelvic bones in a crash.
It should never be worn over the abdomen, which
could cause severe or even fatal internal injuries in
a crash.
Also see “Rear Safety Belt Comfort Guides” under
Lap-Shoulder Belt on page 2‑25.
According to accident statistics, children and infants are
safer when properly restrained in the rear seating
positions than in the front seating positions.
In a crash, children who are not buckled up can strike
other people who are buckled up, or can be thrown out
of the vehicle. Older children need to use safety belts
properly.
{WARNING:
Never do this.
Never allow two children to wear the same safety
belt. The safety belt can not properly spread the
impact forces. In a crash, the two children can be
crushed together and seriously injured. A safety
belt must be used by only one person at a time.
2-34

{WARNING:
Never do this.
Children who are up against, or very close to, any
airbag when it inflates can be seriously injured or
killed. Never put a rear-facing child restraint in the
right front seat. Secure a rear-facing child restraint
in a rear seat. It is also better to secure a(Continued)
WARNING: (Continued)
forward-facing child restraint in a rear seat. If you
must secure a forward-facing child restraint in the
right front seat, always move the front passenger
seat as far back as it will go.
