To turn off the right front passenger's air bag, insert
your ignition key into the switch, push in, and move the
switch to AIR BAG OFF.The AIR BAG OFF light will come on to let you know
that the right front passenger's air bag is off. The right
front passenger's air bag will remain off until you turn it
back on again, and the AIR BAG OFF light will stay on
to remind you that the air bag is off.
CAUTION:
If the air bag readiness light ever comes on when
you have turned off the air bag, it means that
something may be wrong with the air bag system.
The right front passenger's air bag could inflate
even though the switch is off. If this ever
happens, don't let anyone whom the national
government has identified as a member of a
passenger air bag risk group sit in the right front
passenger's position (for example, don't secure a
rear
-facing child restraint in your vehicle) until
you have your vehicle serviced.

To turn the right front passenger's air bag on again,
insert your ignition key into the switch, push in, and
move the switch to the ON position.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts of the air bag system in several places
around your vehicle. You don't want the system to
inflate while someone is working on your vehicle. Your
dealer and the service manual have information about
servicing your vehicle and the air bag system. To
purchase a service manual, see ªService and Owner
Publicationsº in the Index.
CAUTION:
For up to two minutes after the ignition key is
turned off and the battery is disconnected, an air
bag can still inflate during improper service. You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do so.
The air bag system does not need regular maintenance.

1-30 Adding Equipment to Your Air
Bag-Equipped Vehicle
Q:If I add a push bumper or a bicycle rack to the
front of my vehicle, will it keep the air bags
from working properly?
A:As long as the push bumper or bicycle rack is
attached to your vehicle so that the vehicle's basic
structure isn't changed, it's not likely to keep the
air bags from working properly in a crash.
Q:Is there anything I might add to the front of the
vehicle that could keep the air bags from
working properly?
A:Yes. If you add things that change your vehicle's
frame, bumper system, front end sheet metal or
height, they may keep the air bag system from
working properly. Also, the air bag system may not
work properly if you relocate any of the air bag
sensors. If you have any questions about this, you
should contact Customer Assistance before you
modify your vehicle. (The phone numbers and
addresses for Customer Assistance are in Step Two of
the Customer Satisfaction Procedure in this manual.
See ªCustomer Satisfaction Procedureº in the Index.)
Center Passenger Position
Lap Belt
If your vehicle has a bench seat, someone can sit in the
center position.

1-31
When you sit in a center seating position, you have a lap
safety belt, which has no retractor. To make the belt
longer, tilt the latch plate and pull it along the belt.To make the belt shorter, pull its free end as shown until
the belt is snug.
Buckle, position and release it the same way as the lap
part of a lap
-shoulder belt. 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.

1-32
Rear Seat Passengers
(Extended Cab Jump Seats)
Lap Belt
These are reserve seating positions equipped with lap belts
only. (If your extended cab pickup has the optional side
access panel, there's only one reserve seating position.)
It's very important for rear seat passengers to buckle up!
Accident statistics show that unbelted people in the rear
seat are hurt more often in crashes than those who are
wearing safety belts.Rear passengers who aren't safety belted can be thrown
out of the vehicle in a crash. And they can strike others
in the vehicle who are wearing safety belts.
Each jump seat has a lap belt with no retractor.
To make the belt longer, tilt the latch plate and pull it
along the belt.

1-33
To make it shorter, pull the belt as shown until it is snug.
Buckle and position it the same way as the lap part of
the driver's safety belt (see ªDriver Positionº in the
Index). 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. To unlatch the belt, just
push the button on the buckle.
Don't use child restraints on these seats. They won't
work properly.
Children
Everyone in a vehicle needs protection! That includes
infants and all children smaller than adult size. 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.
Smaller Children and Babies
CAUTION:
Children who are up against, or very close to, any
air bag when it inflates can be seriously injured
or killed. Air bags plus lap
-shoulder belts offer
the best protection for adults, but not for young
children and infants. Neither the vehicle's safety
belt system nor its air bag 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.

1-34
CAUTION:
Smaller children and babies should always be
restrained in a child or infant restraint. The
instructions for the restraint will say whether it is
the right type and size for your child. A very
young child's hip bones are so small that a
regular belt might not stay low on the hips, as it
should. Instead, the belt will likely be over the
child's abdomen. In a crash, the belt would apply
force right on the child's abdomen, which could
cause serious or fatal injuries. So, be sure that
any child small enough for one is always properly
restrained in a child or infant restraint.
Infants need complete support, including support for the
head and neck. This is necessary because an infant's
neck is weak and its head weighs so much compared
with the rest of its body. In a frontal crash, an infant in a
rear
-facing restraint settles into the restraint, so the crash
forces can be distributed across the strongest part of the
infant's body, the back and shoulders. A baby should be
secured in an appropriate infant restraint. This is so
important that many hospitals today won't release a
newborn infant to its parents unless there is an
infant restraint available for the baby's first trip in a
motor vehicle.

1-35
CAUTION:
Never hold a baby in your arms while riding in a
vehicle. A baby doesn't weigh much
-- until a
crash. During a crash a baby will become so
heavy you can't hold it. For example, in a crash
at only 25 mph (40 km/h), a 12
-lb. (5.5 kg) baby
will suddenly become a 240
-lb. (110 kg) force on
your arms. The baby would be almost impossible
to hold.
Secure the baby in an infant restraint, but be
sure to turn off the passenger's air bag. See ªAir
Bag Off Switchº and ªSecuring a Child Restraint
in the Right Front Seat Positionº in the Index
for more on this, including important
safety information.

Child Restraints
Every time infants and young children ride in
vehicles, they should have protection provided by
appropriate restraints.
Q:What are the different types of add-on
child restraints?
A:Add-on child restraints are available in four basic
types. When selecting a child restraint, take into
consideration not only the child's weight and size,
but also whether or not the restraint will be
compatible with the motor vehicle in which it
will be used.

1-37
An infant car bed (A) is a special bed made for use
in a motor vehicle. It's an infant restraint system
designed to restrain or position a child on a
continuous flat surface. With an infant car bed,
make sure that the infant's head rests toward the
center of the vehicle.A rear-facing infant restraint (B) positions an infant
to face the rear of the vehicle. Rear
-facing infant
restraints are designed for infants of up to about
20 lbs. (9 kg) and about one year of age. This type
of restraint faces the rear so that the infant's head,
neck and body can have the support they need in
a frontal crash. Some infant seats come in two
parts
-- the base stays secured in the vehicle and
the seat part is removable.
