Safety
information
WARNING
To ensure the front-seat passenger airbag
function, the system must be able to detect
whether a person is sitting in the front passenj ger seat. The entire seat cushion area must be
used for this purpose. There is a risk of injuries or danger to life. Make sure that the front pasj
senger keeps his or her feet in the floor area.
Malfunction
of
the
automatic

instance a correctly seated person of suffij cient size is detected on the seat. The airj
bags on the front passenger side are actij vated.
Detected
child
restraint
systems
The system generally detects children seated in
a child restraint system, particularly in child rej
straint systems required by NHTSA at the point
in time when the vehicle was manufactured. Afj
ter installing a child restraint system, make sure that the indicator light for the front-seat passenj
ger airbags lights up. This indicates that the child
restraint system has been detected and the
front-seat passenger airbags are not activated.
Strength
of
