" Side airbags
In response to a severe side impact, the side airbags for
the driver or front passenger work together with the seat
belts to help reduce injury by inflating. The side airbags
help to reduce injuries mainly to the driver's or front
passenger's chest.
The side airbag on the passenger seat will not activate if there
is no passenger sitting in the front passenger seat. However,
the side airbag on the passenger seat may deploy if luggage
is put in the seat, or the seat belt is buckled up regardless of
the presence of the occupant in the seat.
Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver and passenger when the side airbags are
inflated.
Be sure to wear your seat belt properly.
