How to Wear Safety Belts Properly
Adults
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 the part of this manual called ªChildren.º
Follow those rules for everyone's protection.
First, you'll want to know which restraint systems your
vehicle has.
We'll start with the driver position.
Driver Position
This part describes the driver's restraint system.
Lap-Shoulder Belt
The driver has a lap-shoulder belt. Here's how to wear
it properly.
1. Close and lock the door.
2. Adjust the seat (to see how, see ªSeatsº in the Index)
so you can sit up straight.
3. Pick up the latch plate and pull the belt across you.
Don't let it get twisted.
4. 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 isn't long enough, see ªSafety Belt
Extenderº at the end of this section.
Make sure the release button on the buckle is positioned
so you would be able to unbuckle the safety belt quickly
if you ever had to.

The best way to protect the fetus is to protect the
mother. When a safety belt is worn properly, it's more
likely that the fetus won't 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, see ªDriver Positionº earlier in this section.
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 lap portion of the belt out all the way,
you will engage the child restraint locking feature. If
this happens, just let the belt go back all the way and
start again.
Air Bag System
This part explains the air bag system.
Your vehicle has ªNext Generationº frontal air
bags
-- one air bag for the driver and another air bag
for the right front passenger.
Next Generation frontal air bags are designed to help
reduce the risk of injury from the force of an inflating
air bag. But even these air bags must inflate very
quickly if they are to do their job and comply with
federal regulations.Here are the most important things to know about the air
bag system:
CAUTION:
You can be severely injured or killed in a crash if
you aren't wearing your safety belt
-- even if you
have air bags. Wearing your safety belt during a
crash helps reduce your chance of hitting things
inside the vehicle or being ejected from it. Air
bags are ªsupplemental restraintsº to the safety
belts. All air bags
-- even Next Generation air
bags
-- are designed to work with safety belts,
but don't replace them. Air bags are designed to
work only in moderate to severe crashes where
the front of your vehicle hits something. They
aren't designed to inflate at all in rollover, rear,
side or low
-speed frontal crashes. And, for
unrestrained occupants, Next Generation air
bags may provide less protection in frontal
crashes than more forceful air bags have
provided in the past. Everyone in your vehicle
should wear a safety belt properly
-- whether or
not there's an air bag for that person.

4. Pull the rest of the shoulder belt all the way out of
the retractor to set the lock.5. To tighten the belt, feed the shoulder belt back into the
retractor while you push down on the child restraint. If
you're 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.
6. Push and pull the child restraint in different
directions to be sure it is secure.
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.

Your vehicle has one
double
-sided key for the
ignition and all door locks.
If you ever lose your key, your dealer will be able to
assist you with obtaining a new one.Door Locks
CAUTION:
Unlocked doors can be dangerous.
Passengers -- especially children -- can easily
open the doors and fall out. When a door is
locked, the inside handle won't open it.
Outsiders can easily enter through an unlocked
door when you slow down or stop your vehicle.
This may not be so obvious: You increase the
chance of being thrown out of the vehicle in a
crash if the doors aren't locked. Wear safety belts
properly, lock your doors, and you will be far
better off whenever you drive your vehicle.
There are several ways to lock and unlock your vehicle.
From the outside, use your key.

On the passenger side of the
rear cargo door or tailgate,
there is a power lock switch
which can be used to lock or
unlock all of the doors.
On vehicles with cargo doors, if the rear cargo lock
switch is pressed with the cargo doors open, all of the
doors will lock five seconds after the cargo doors are
closed. If the cargo doors are closed, the vehicle's doors
will lock when a power door lock switch is pressed.Child Security Locks (If Equipped)
With this feature, you can
lock the rear side doors so
they can't be opened from
the inside by passengers.
Move the button up to engage the security feature.
Move the button down to return the door locks to
normal operation.
Leaving Your Vehicle
If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out, and
close the door.
