If the ON indicator still remains illuminated
while the OFF indicator turns off after
taking relevant corrective actions

inspection, it is recommended that on
subsequent trips the small adult always
take the rear seat.

front passenger’s seat, the SUBARU
advanced frontal airbag system may or
may not activate th e front passenger’s
SRS frontal airbag depending on the
