manual on-off switch is on. ( P. 51) The force of the rapid inflation of the frontpassenger airbag can cause death or serious
injury to children in the event of an accident.

WARNING
■When using a child restraint system
●When a junior seat is installed, always ensure that the shoulder belt is positioned across the center of the child’s shoulder. Th e belt should be kept away from the child’s
neck, but not so that it could fall off the child’s shoulder.
●Use child restraint system suitable to the age and size of the child and install it to the rear seat.
●Only put a forward-facing child restraint sys-
tem on the front seat when unavoidable. When installing a forward-facing childrestraint on the front passenger seat, move
the seat as far back as possible. Failing to do so may result in death or serious injury if theairbags deploy (inflate).
●Do not allow the child to lean his/her head orany part of his/her body against the door orthe area of the seat, front or rear pillars, or
roof side rails from which the SRS side airbags or SRS curtain shield airbags deployeven if the child is seat ed in the child restraint
system. It is dangerous if the SRS side airbags and curtain shield airbags inflate, and theimpact could cause death or serious injury to
the child.
●If the driver’s seat interferes with the childrestraint system and prevents it from being
attached correctly, attach the child restraint system to the right-hand rear seat (left-handdrive vehicles) or the left-hand rear seat
(right-hand drive vehicles). ( P. 65, 72)
