For safety and security
■Unoccupied
■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 not re cognize him/her as an adult depending on
his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: For some children, child in se at, child in booster seat or child in convertible seat, the sys-
tem may not recognize him/her as a child. F actors which may affect this can be the phy-
sique or posture.
*5: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint syst em should only be installed on the front passenger seat
when it is unavoidable. ( P.45)
*6: In case the indicator light is not illuminated, consult this manual on how to install the child
restraint system properly. ( P.46)
