114 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
NOTE: If there are child seats in both of the outboard (left
and right) seating positions, the tether strap hooks of
both child seats should be connected to the center tether
strap loop. This is the correct way to tether two outboard
child seats.
Center Seat:
1. Raise the head restraint and reach between the rear
seat and rear glass to access the tether strap loop.

2. Place a child restraint on the seat and adjust the tether
strap so that it will reach over the seat back, under the
head restraint, through the tether strap loop behind
the seat and over to the tether strap loop behind either
the right or left outboard seat.
