Vehicles with Rear Seats
The top tether anchors are located in a storage
compartment behind the rear seats. Lift the
lid of the storage compartment to access the
anchors. You may have to fold back the cargo mat
to access the storage compartment and the top
tether anchors. Be sure to use an anchor located
on the same side of the vehicle as the seating
position where the child restraint will be placed.
Vehicles without Rear Seats
If the vehicle does not have rear seats, there will
be an exposed top tether anchor for the front
passenger position located on the floor behind the
front passenger's seat.
