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 babies. If a child will be
riding in your vehicle, seeOlder Children on page 1-29
orInfants and Young Children on page 1-32. 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.
First, before you or your passenger(s) wear a safety
belt, there is important information you should know.Sit up straight and always keep your feet on the floor in
front of you. The lap part of the belt should be worn low
and snug on the hips, just touching the thighs. In a crash,
this applies force to the strong pelvic bones and you
would be less likely to slide under the lap belt. If you slid
under it, the belt would apply force on your abdomen.
This could cause serious or even fatal injuries. The
shoulder belt should go over the shoulder and across
the chest. These parts of the body are best able to take
belt restraining forces.
The shoulder belt locks if there is a sudden stop or crash.

If you ever pull the shoulder portion of a passenger
belt out all the way, you may engage the child
restraint locking feature. If this happens, just 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, seeSafety Belt
Extender on page 1-28.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle the
safety belt quickly if necessary.4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
See “Shoulder Belt Height Adjustment” later
in this section.
5. 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.

{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 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 LATCH attachment parts and
the vehicle’s safety belt assembly.Folding an empty rear seat with the safety belts
secured may cause damage to the safety belt or
the seat. When removing the child restraint,
always remember to return the safety belts to
their normal, stowed position before folding
the rear seat.
1. Attach and tighten the lower attachments to the
lower anchors. If the child restraint does not have
lower attachments or the desired seating position
does not have lower anchors, secure the child
restraint with the top tether and the safety belts.
Refer to your child restraint manufacturer
instructions and the instructions in this manual.
1.1. Find the lower anchors for the desired
seating position.
1.2. Put the child restraint on the seat.
1.3. Attach and tighten the lower attachments
on the child restraint to the lower anchors.

If you need to install more than one child restraint in the
rear seat, be sure to readWhere to Put the Restraint
on page 1-38.
1. Put the child restraint on the seat.
2. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle’s safety belt through or
around the restraint. The child restraint instructions
will show you how.
3. Push the latch plate into the buckle until it clicks.
Make sure the release button is positioned so
you would be able to unbuckle the safety belt
quickly if necessary.4. Pull the rest of the shoulder belt all the way
out of the retractor to set the lock.

5. Pull the rest of the shoulder belt all the way
out of the retractor to set the lock.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 find it
helpful to use your knee to push down on the
child restraint as you tighten the belt.

Keys
{CAUTION:
Leaving children in a vehicle with the ignition
key is dangerous for many reasons, children
or others could be badly injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
The windows will function with the keys in the
ignition and they could be seriously injured or
killed if caught in the path of a closing window.
Do not leave the keys in a vehicle with children.
The key can be used for the ignition and all door locks.
The key has a bar-coded key tag that the dealer/retailer
or qualified locksmith can use to make new keys.
Store this information in a safe place, not in your vehicle.
Notice:If you ever lock your keys in your vehicle,
you may have to damage the vehicle to get in.
Be sure you have spare keys.
If you are locked out of your vehicle, call Roadside
Assistance Center. SeeRoadside Assistance Program
on page 7-6.

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.
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.There are several ways to lock and unlock your vehicle.
If your vehicle is equipped with keyless entry, see
Remote Keyless Entry (RKE) System on page 2-3for
more information.
From the outside, use your key.
To lock the door from the
inside, slide the manual
lever on your door down.
To unlock the door, slide
the manual lever up.
Power Door Locks
On vehicles with power door locks, the switches are
located on the doors.
T:Press the bottom of the switch to lock all the doors
at once. Press the top of the switch to unlock all the
doors at once.
When a door is locked, the inside door handle will
not work.
