or the safety belts!
With safety belts, you slow down as the vehicle does.
You get more time to stop. You stop over more distance,
and your strongest bones take the forces. That is why
safety belts make such good sense.
Questions and Answers About Safety
Belts
Q:Will I be trapped in the vehicle after a crash if I
am wearing a safety belt?
A:Youcouldbe — whether you are wearing a safety
belt or not. But your chance of being conscious
during and after an accident, so youcanunbuckle
and get out, ismuchgreater if you are belted.
And you can unbuckle a safety belt, even if you are
upside down.
Q:If my vehicle has airbags, why should I have to
wear safety belts?
A:Airbags are supplemental systems only; so they
workwithsafety belts — not instead of them.
Whether or not an airbag is provided, all occupants
still have to buckle up to get the most protection.
That is true not only in frontal collisions, but
especially in side and other collisions.

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
or near frontal crash if the threshold conditions for
pretensioner activation are met. And, if your 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 1-71.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.There is one guide for each outside passenger position
in the rear seat. Here is how to install the comfort
guide to the shoulder belt:
1. Slide the guide off of its storage clip located
between the interior body and the seatback or from
the storage pocket on the side of the seat.
2. Place the guide over the belt and insert the two
edges of the belt into the slots of the guide.

Infants and Young Children
Everyone in a vehicle needs protection! This includes
infants and all other children. Neither the distance
traveled nor the age and size of the traveler changes
the need, for everyone, to use safety restraints. In fact,
the law in every state in the United States and in
every Canadian province says children up to some age
must be restrained while in a vehicle.
{CAUTION:
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Never leave
children unattended in a vehicle and never allow
children to play with the safety belts.
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. Every time
infants and young children ride in vehicles, they should
have the protection provided by appropriate child
restraints.
Children who are not restrained properly can strike
other people, or can be thrown out of the vehicle.

{CAUTION:
Never do this.
Children who are up against, or very close to, any
airbag when it inates 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
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.
1-37

Where to Put the Restraint
According to accident statistics, children and infants are
safer when properly restrained in a child restraint
system or infant restraint system secured in a rear
seating position.
We recommend that children and child restraints be
secured in a rear seat, including: an infant or a
child riding in a rear-facing child restraint; a child riding
in a forward-facing child seat; an older child riding in
a booster seat; and children, who are large enough,
using safety belts.
A label on the sun visor says, “Never put a rear-facing
child restraint in the front.” This is because the risk
to the rear-facing child is so great, if the airbag deploys.
{CAUTION:
A child in a rear-facing child restraint can be
seriously injured or killed if the right front
passenger airbag inates. This is because the
back of the rear-facing child restraint would be
very close to the inating airbag. A child in a
CAUTION: (Continued)
CAUTION: (Continued)
forward-facing child restraint can be seriously
injured or killed if the right front passenger airbag
inates and the passenger seat is in a forward
position.
Even if the passenger sensing system has turned
off the right front passenger frontal airbag, no
system is fail-safe. No one can guarantee that an
airbag will not deploy under some unusual
circumstance, even though it is turned off.
Secure rear-facing child restraints in a rear
seat, even if the airbag is off. If you secure a
forward-facing child restraint in the right front seat,
always move the front passenger seat as far back
as it will go. It is better to secure the child restraint
in a rear seat.
SeePassenger Sensing System on page 1-64for
additional information.
When securing a child restraint in a rear seating
position, study the instructions that came with the child
restraint to make sure it is compatible with this
vehicle.
