Sensing System for Passenger
Airbag
The passenger sensing system, if equipped, will turn off
the right front passenger frontal airbag under certain
conditions. The driver airbags, seat‐mounted side
impact airbags, if equipped, and roof‐rail airbags are
not affected by this.
If the vehicle has one of the indicators pictured in the
following illustrations, then the vehicle has a passenger
sensing system for the right front passenger position.
The passenger airbag status indicator, if equipped, will
be visible on the overhead console when the vehicle is
started.

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 with a
free‐falling latch plate 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, if equipped.
See Passenger Sensing System
on page 2‑94for more information.If the belt stops before it reaches the buckle, for
lap‐shoulder belts with cinching latch plates, tilt the
latch plate and keep pulling the safety belt until it
can be buckled.

Safety Belt Pretensioners
This vehicle has safety belt pretensioners for
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, if the vehicle has 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. SeeReplacing Restraint System Parts After a
Crash on page 2‑102.
Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort
guides. If not, they are available through your dealer.
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. There is one guide, if equipped, for each outside
passenger position in the second row seat and the
third row, if the vehicle has one. Here is how to install
a comfort guide to the safety belt:Second Row
1. For the second row, remove the guide from its storage clip on the interior body.

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 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.
2-55

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 2‑46for 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. 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 2‑46.
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.
