Questions and Answers About
Safety Belts
Q: Will I be trapped in the vehicleafter a crash if I am wearing a
safety belt?
A: You could be—whether you are
wearing a safety belt or not. But
your chance of being conscious
during and after an accident, so
you canunbuckle and get out, is
much greater 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 work with
safety 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. Q: If I am a good driver, and I
never drive far from home,
why should I wear safety
belts?
A: You may be an excellent driver,
but if you are in a crash —even
one that is not your fault —you
and your passenger(s) can be
hurt. Being a good driver does
not protect you from things
beyond your control, such as
bad drivers.
Most accidents occur within
40 km (25 miles) of home. And
the greatest number of serious
injuries and deaths occur at
speeds of less than
65 km/h (40 mph).
Safety belts are for everyone.
How to Wear Safety Belts
Properly
This section is only for people of
adult size.
Be aware that there are special
things to know about safety belts
and children. And there are different
rules for smaller children and
infants. If a child will be riding in the
vehicle, see Older Children
on
page 2‑40or Infants and Young
Childrenon page 2‑42. Follow
those rules for everyone's
protection.
It is very important for all occupants
to buckle up. Statistics show that
unbelted people are hurt more often
in crashes than those who are
wearing safety belts.
Occupants who are not buckled up
can be thrown out of the vehicle in a
crash. And they can strike others in
the vehicle who are wearing safety
belts.
Seats and Restraints 2-19
Lap-Shoulder Belt
All seating positions in the vehicle
have a lap-shoulder belt.
The following instructions explain
how to wear a lap-shoulder belt
properly.
1. Adjust the seat, if the seat isadjustable, 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.3. Push the latch plate into the
buckle until it clicks. 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 2‑23.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
If equipped with a shoulder belt
height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height
Adjustment” later in this section
for instructions on use and
important safety information.
4. To make the lap part tight, pull up on the shoulder belt.
It may be necessary to pull
stitching on the safety belt
through the latch plate to fully
tighten the lap belt on smaller
occupants.
Seats and Restraints 2-21
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 and near
frontal crash if the threshold
conditions for pretensioner
activation are met.
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 Safety Belt System Parts
After a Crash on page 2‑24.
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 olderchildren 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 for each outside
passenger position in the rear seat.
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. Place the guide over the belt,and insert the two edges of the
belt into the slots of the guide.
Seats and Restraints 2-23
The best way to protect the fetus is
to protect the mother. When a safety
belt is worn properly, it is more likely
that the fetus will not be hurt in a
crash. For pregnant women, as for
anyone, the key to making safety
belts effective is wearing them
properly.
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.
Safety System Check
Now and then, check that the safety
belt reminder light, safety belts,
buckles, latch plates, retractors and
anchorages are working properly.
Look for any other loose or
damaged safety belt system parts
that might keep a safety belt system
from doing its job. See your dealer/
retailer to have it repaired. Torn or
frayed safety belts may not protect
you in a crash. They can rip apart
under impact forces. If a belt is torn
or frayed, get a new one right away.
Make sure the safety belt reminder
light is working. SeeSafety Belt
Reminders
on page 4‑15for more
information.
Keep safety belts clean and dry.
See Safety Belt Care
on
page 2‑23.
Safety Belt Care
Keep belts clean and dry.
{WARNING
Do not bleach or dye safety belts.
It may severely weaken them. In
a crash, they might not be able to
provide adequate protection.
Clean safety belts only with mild
soap and lukewarm water.
2-26 Seats and Restraints
{WARNING
Airbags inflate with great force,
faster than the blink of an eye.
Anyone who is up against, or very
close to, any airbag when it
inflates can be seriously injured
or killed. Do not sit unnecessarily
close to the airbag, as you would
be if you were sitting on the edge
of your seat or leaning forward.
Safety belts help keep you in
position before and during a(Continued)
WARNING (Continued)
crash. Always wear your safety
belt, even with airbags. The driver
should sit as far back as possible
while still maintaining control of
the vehicle.
Occupants should not lean on or
sleep against the door or side
windows in seating positions with
seat-mounted side impact airbags
and/or roof-rail airbags.
{WARNING
Children who are up against,
or very close to, any airbag when
it inflates can be seriously injured
or killed. 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. Young
children and infants need the
protection that a child restraint
system can provide. Always
secure children properly in your
vehicle. To read how, see Older
Children
on page 2‑40or Infants
and Young Children
on
page 2‑42
.
Seats and Restraints 2-33
According to accident statistics,
children are safer when properly
secured in a rear seat in the correct
child restraint for their weight
and size.
We recommend that children 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 seat in
the front.”This is because the risk to
the rear-facing child is so great,
if the airbag deploys.{WARNING
A child in a rear-facing child
restraint can be seriously injured
or killed if the right front
passenger airbag inflates. This is
because the back of the
rear-facing child restraint would
be very close to the inflating
airbag. A child in a forward-facing
child restraint can be seriously
injured or killed if the right front
passenger airbag inflates and the
passenger seat is in a forward
position.
(Continued)
WARNING (Continued)
Even if the passenger sensing
system has turned off the right
front passenger frontal airbag and
seat-mounted side impact airbag
(if equipped), no system is
fail-safe. No one can guarantee
that an airbag will not deploy
under some unusual
circumstance, even though the
airbag(s) are off.
Secure rear-facing child restraints
in a rear seat, even if the
airbag(s) are 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.
