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 an accident — even one that is not your
fault — you and your passengers can be hurt.
Being a good driver does not protect you
from things beyond your control, such as bad
drivers.
Most accidents occur within 25 miles (40 km)
of home. And the greatest number of
serious injuries and deaths occur at speeds of
less than 40 mph (65 km/h).
Safety belts are for everyone.
How to Wear Safety Belts Properly
This part 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 babies.
If a child will be riding in your vehicle, see
Older Children on page 61orInfants and Young
Children on page 64. Follow those rules for
everyone’s protection.
First, you will want to know which restraint
systems your vehicle has.
We will start with the driver position.
Driver Position
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here is how to
wear it properly.
1. Close and lock the door.
2. Adjust the seat so you can sit up straight.
To see how, see “Seats” in the Index.

Safety Belt Use During Pregnancy
Safety belts work for everyone, including pregnant
women. Like all occupants, they are more likely
to be seriously injured if they do not wear
safety belts.
A pregnant woman should wear a lap-shoulder
belt, and the lap portion should be worn as low as
possible, below the rounding, throughout the
pregnancy.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.
Right Front Passenger Position
To learn how to wear the right front passenger’s
safety belt properly, seeDriver Position on
page 43.
The right front passenger’s safety belt works the
same way as the driver’s safety belt — except
for one thing. If you ever pull the shoulder portion
of the belt out all the way, you will engage the
child restraint locking feature which may turn off
the passenger’s frontal airbag. If this happens, just
let the belt go back all the way and start again.
51

The safety belt locks if there is a sudden stop or a
crash, or if you pull the belt very quickly out of
the retractor.
{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 against your body.
To unlatch the belt, push the button on the buckle.
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.
56

{CAUTION:
Each top tether anchor and lower anchor
in the vehicle is designed to hold only
one child restraint. 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 if this
happens. To help prevent injury to people
and damage to your vehicle, 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. Secure any unused
safety belts behind the child restraint so
children cannot reach them. Pull the
shoulder belt all the way out of the
retractor to set the lock, if your vehicle
has one, after the child restraint has
been installed. Be sure to follow the
instructions of the child restraint
manufacturer.
Notice:Contact between the child restraint or
the LATCH attachment parts and the vehicle’s
safety belt assembly may cause damage to
these parts. Make sure when securing unused
safety belts behind the child restraint that
there is no contact between the child restraint
or the LATCH attachment parts and the
vehicle’s safety belt assembly.
80

4. Pull the rest of the shoulder belt all the way
out of the retractor to set the lock.5. To tighten the belt, push down on the child
restraint, pull the shoulder portion of the belt
to tighten the lap portion of the belt and
feed the shoulder belt back into the retractor.
If you are using a forward-facing child
restraint, you may nd it helpful to use your
knee to push down on the child restraint
as you tighten the belt.
84

6. To tighten the belt, push down on the child
restraint, pull the shoulder portion of the belt
to tighten the lap portion of the belt and
feed the shoulder belt back into the retractor.
If you are using a forward-facing child
restraint, you may nd it helpful to use your
knee to push down on the child restraint
as you tighten the belt. You should not be able
to pull more of the belt from the retractor
once the lock has been set.
7. Push and pull the child restraint in different
directions to be sure it is secure.8. If the airbag is off, the off indicator will be lit
and stay lit when the key is turned to RUN
or START.
If a child restraint has been installed and the
on indicator is lit, turn the vehicle off. Remove the
child restraint from the vehicle and reinstall the
child restraint.
If after reinstalling the child restraint and restarting
the vehicle, the on indicator is still lit, check to
make sure that the vehicle’s seatback is not
pressing the child restraint into the seat cushion.
If this happens, slightly recline the vehicle’s
seatback and adjust the seat cushion if possible.
Also make sure the child restraint is not trapped
under the vehicle head restraint. If this happens,
adjust the head restraint.
If the on indicator is still lit, secure the child in
the child restraint in a rear seat position in
the vehicle and check with your dealer.
To remove the child restraint, just unbuckle the
vehicle’s safety belt and let it go back all the way.
The safety belt will move freely again and be
ready to work for an adult or larger child
passenger.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers, especially children, can
easily open the doors and fall out
of a moving vehicle. When a door is
locked, the handle will not open it.
You increase the chance of being
thrown out of the vehicle in a crash if
the doors are not locked. So, wear
safety belts properly and lock the
doors whenever you drive.
CAUTION: (Continued)
CAUTION: (Continued)

Young children who get into unlocked
vehicles may be unable to get out. A
child can be overcome by extreme
heat and can suffer permanent injuries
or even death from heat stroke.
Always lock your vehicle whenever
you leave it.
Outsiders can easily enter through an
unlocked door when you slow down
or stop your vehicle. Locking your
doors can help prevent this from
happening.
