Installation of Child Seat
All child restraint systems are designed to be secured by lap belts or
the lap belt portion of a lap-shoulder belt. Children could be
endangered in a crash, if their child restraints are not properly
secured. Follow the child seat manufacturer's instructions when
installing the seat.
Your Honda automobile is equipped with attachment points
specifically for a rear seat mounted child restraint system which
uses a top tether.
The tether attachment points are located on the rear tray, just
behind the rear seat-back.
The automatic lap/shoulder restraint system at the front passenger
seat cannot be used to secure a child restraint system. Instead, an
optional lap belt must be installed specifically for securing a child
restraint system. Two anchor points have been provided behind the
front passenger seat for installation. The optional lap belt is available
from your Honda dealer.
