seat. The weight of a child restraint and its
"footprint" vary for different kinds of chi ld re-
straints and for the d ifferent models of the
same kind of child restraint offered by child
restraint manufacturers .
The weight ranges for the individual types,
makes and mode ls of ch ild restra ints that the
NHTSA has specified in the Safety Standard
together with the weight ranges of typical in-
fants and typical 1 year-old child have been
stored in the control unit of the Advanced Air-
bag System. When a ch ild restrai nt is being
used on the front passenger seat with a typi -
cal 1 yea r-old chi ld, the Advanced Airbag Sys-
tem compares the weight measured by the
weight sensing mat with the information stor-
ed in the electronic contro l unit.
The electron ic cont rol unit a lso registers the
tension on the front passenger safety belt.
The tension on the safety be lt for the front
passenger seat will be different for an adult
who is properly using the safety belt as com-
pared to the tension on the belt when it is
used to attach a child restraint to the seat.
The sensor below the latch for the safety belt
for the front seat passenger measures the
tension on the be lt . The input from this sen-
sor is then used with the we ight to "dec ide",
whe t her there is a ch ild restraint w ith a typ ical
1 year-o ld child on the front passenger seat
and whether or not the airbag must be turned
off.
Child restraints and Advanced Airbags
Regardless of the child restraint that you use,
make sure that it has been certified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu-
facturer for use with an airbag . Always be sure
that the ch ild restraint is properly insta lled at
one of the rear seat ing pos itions . If in excep-
tional circumstances you must use it on the
front passenger seat, carefu lly read all of the
info rmation on child safety and Advanced Air-
bags and heed a ll of the applicable WARN-
INGS. Make certain that the child restraint is
correctly recognized by the weig ht-sensing
mat inside the front passenger seat, that the
front passenger airbag is turned off and that
the a irbag status is a lways correct ly signa led
by the
PASSENGER AIR BAG OFF
light.
Many types and models of child restraints
have been available over the years, new mod-
els are introduced regu larly incorporating new
and improved des igns and o lder models are
taken out of product ion. Child restraints are
not standard ized . Child restraints of the same
type typically have d ifferent weights and sizes
and different 'footpr ints,' the size and shape
of the bo ttom of the ch ild restra int t hat sits
on the seat, when they are inst all ed on a vehi-
cle seat. These d ifferences make it virtually
impossible to certify compliance with the re -
quirements for advanced airbags with each
and every ch ild restraint that has ever been
sold in the past or will be sold over the course
of the useful life of your veh icle.
For this reason, the United States National
Highway Traffic Safety Administrat ion has
published a list of spec ific type, makes and
models of child restraints that mus t be used
to certify comp liance of the Advanced Airbag
System in your veh icle w ith the suppression
requirements of Federal Motor Vehicle Safety
Standard 208. These chi ld restraints are :
