Rear Seat Operation (All Split Bench
and Hybrid Full Bench)

Folding Rear Seat

On a vehicle with a second row 60/40 split seat either
side of the rear seat may be folded for added cargo
space.
Notice: Folding a rear seat with the safety belts still
fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts and
return them to their normal stowed position before
folding a rear seat.
Make sure that nothing is on the seat.
To fold the seat, slowly pull the seat cushion up.
To return the seat to the normal seating position, slowly
pull the seat cushion down.
WARNING:
A safety belt that is improperly routed, not
properly attached, or twisted will not provide the
protection needed in a crash. The person wearing
the belt could be seriously injured. After raising
the rear seatback, always check to be sure that
the safety belts are properly routed and attached,
and are not twisted.
