CAUTION:
{
If something is between an occupant and an
airbag, the airbag might not inflate properly
or it might force the object into that person
causing severe injury or even death. The path
of an inflating airbag must be kept clear.
Do not put anything between an occupant and
an airbag, and do not attach or put anything
on the steering wheel hub or on or near any
other airbag covering.
Do not use seat accessories that block the
inflation path of a seat-mounted side impact
airbag.
