There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may recognize him/
her as a child depending on his/her physique and posture.
*2: In the event the front passenger does not wear a seat belt.
*3: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/her as an
adult depending on his/her physique or posture.
*4: Never install a rear-facing child restraint system on the front passen- ger seat. A forward-facing child restraint system should only be
installed on the front passenger seat when it is unavoidable.
(→ P. 1 0 8 )
*5: In case the indicator is not illuminated, consult this manual as for installing the child restraint system properly. ( →P. 112)
