Child Safety Seats
In the rear seats, install LATCH child safety
seats in the outboard seating positions only.
Use only a seat belt retained seat in the center
position.
To install a LATCH child safety seat, carefully
read and follow the instructions provided by
the manufacturer of the child restraint system.
These instructions describe how to slide the
child restraint system onto the seat's anchor
bars until you hear it "click" into place. You
may need to push the child restraint system
firmly against the seat back to ensure it fits
snugly.
