Returning the Seat to the Seating Position
WARNING: Make sure that cargo or any objects are not trapped
underneath the seat cushion before returning the seat cushion to
its original position, and that the seat cushion locks into place. Failure
to do so may prevent the seat from operating properly in the event of a
crash, which could increase the risk of serious injury.
1. Pull the control on the side of the seat to release the seat cushion
from the storage position.
2. Push the seat cushion down until it locks into the horizontal position.
Folding Up the Rear Seats (SuperCrew Vehicles Only)
The rear seat has a split 60/40 cushion. Each seat cushion can be flipped
up into a vertical storage position.
Note: The handle on the bottom of the seat cushion does not need to be
pulled to lift the seat cushion to the storage position.
