CAUTION:
{
If the right front passenger's air bag is turned
off for a person who isn't in a risk group
identified by the national government, that
person won't have the extra protection of an
air bag. In a crash, the air bag wouldn't be able
to inflate and help protect the person sitting
there. Don't turn off the passenger's air bag
unless the person sitting there is in a risk
group. See "Air Bag Off Switch" in the
Index for more on this, including important
safety information.
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 the right front passenger's seat)
until you have your vehicle serviced. See "Air
Bag Off Switch" for more on this, including
important safety information.
