Seating and Safety Restraints
For Convertible only:
1. Route the child safety seat tether strap over the back of the seat.
For vehicles with adjustable head restraints, route the tether strap under
the head restraint and between the head restraint posts, otherwise route
the tether strap over the top of the seatback.
The tether anchors on the
convertible are located rearward of
the seatback in the convertible top
sling.
Note: For easier access, attach the
tether with the convertible top up.
Note: The attachments for the
convertible boot located on the back
of the head restraints are not tether
anchors.
