Protecting Adults
Do not place hard or sharp objects
between yourself and an airbag.
Carrying hard or sharp objects on
your lap, or driving with a pipe or
other sharp object in your mouth,
can result in injuries if your
airbags inflate.
Keep your hands and arms away
from the airbag covers.
If your hands or arms are close to
the SRS covers in the center of the
steering wheel and on top of the
dashboard, they could be injured if
the airbags inflate.
