CAUTION:
{
A child in a rear-facing child restraint can be
seriously injured or killed if the passenger's
airbag inflates. This is because the back of the
rear-facing child restraint would be very close
to the inflating airbag. Do not use a rear-facing
child restraint in this vehicle unless the
passenger's airbag has been turned off.
Even though the airbag off switch is designed
to turn off the passenger's frontal airbag, no
system is fail-safe, and no one can guarantee
that an airbag will not deploy under some
unusual circumstance, even though it is turned
off. We recommend that rear-facing child
restraints be transported in vehicles with a
rear seat that will accommodate a rear-facing
child restraint, whenever possible.
If you need to secure a forward-facing child
restraint in the right front static seat or the
right front bench seat, always move the
passenger seat as far back as it will go.
