{CAUTION:
Never do this.
Here two children are wearing the same
belt. The belt can not properly spread the
impact forces. In a crash, the two children
can be crushed together and seriously
injured. A belt must be used by only one
person at a time.
Q:What if a child is wearing a lap-shoulder
belt, but the child is so small that the
shoulder belt is very close to the child’s
face or neck?
A:If the child is sitting in a seat next to a
window, move the child toward the center of
the vehicle. Also seeRear Safety Belt
Comfort Guides on page 41. If the child is
sitting in the center rear seat passenger
position, move the child toward the safety belt
buckle. In either case, be sure that the
shoulder belt still is on the child’s shoulder, so
that in a crash the child’s upper body would
have the restraint the belts provide.

A booster seat (F-G) is a child restraint designed
to improve the t of the vehicle’s safety belt
system. Some booster seats have a shoulder belt
positioner, and some high-back booster seats
have a ve-point harness. A booster seat can also
help a child to see out the window.
Q:How Should I Use a Child Restraint?
A:A child restraint system is any device designed
for use in a motor vehicle to restrain, seat, or
position children. A built-in child restraint
system is a permanent part of the motor
vehicle. An add-on child restraint system is a
portable one, which is purchased by the
vehicle’s owner. To help reduce injuries, an
add-on child restraint must be secured in
the vehicle. With built-in or add-on child
restraints, the child has to be secured within
the child restraint.
When choosing an add-on child restraint, be
sure the child restraint is designed to be
used in a vehicle. If it is, it will have a label
saying that it meets federal motor vehicle
safety standards. Then follow the instructions
for the restraint. You may nd these
instructions on the restraint itself or in a
booklet, or both.

{CAUTION:
When an airbag inates, there may be
dust in the air. This dust could cause
breathing problems for people with a
history of asthma or other breathing
trouble. To avoid this, everyone in the
vehicle should get out as soon as it is
safe to do so. If you have breathing
problems but cannot get out of the vehicle
after an airbag inates, then get fresh air
by opening a window or a door. If you
experience breathing problems following
an airbag deployment, you should seek
medical attention.In many crashes severe enough to inate an
airbag, windshields are broken by vehicle
deformation. Additional windshield breakage may
also occur from the right front passenger
airbag.
Airbags are designed to inate only once.
After they inate, you will need some new
parts for your airbag system. If you do not get
them, the airbag system will not be there to
help protect you in another crash. A new
system will include airbag modules and
possibly other parts. The service manual for
your vehicle covers the need to replace
other parts.
Your vehicle has a crash sensing and
diagnostic module which records information
after a crash. SeeVehicle Data Collection and
Event Data Recorders on page 650.
Let only qualied technicians work on your
airbag system. Improper service can mean
that an airbag system will not work properly.
See your dealer for service.
