WARNING: The non-adjustable head restraint is a safety device.
It should be installed whenever the seat is occupied.
WARNING: To minimize the risk of neck injury in the event of a
crash, head restraints must be installed properly.
Note: The SuperCab has rear outboard head restraints that are not
removable and are bolted to the back wall.
Folding up the rear seats (SuperCab)
1. Pull control to release seat
cushion.
2. Rotate seat cushion up until it
locks into vertical storage position.
Returning the seat to 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 control on the side of the seat to release seat cushion from
storage position.
2. Push seat cushion down until it locks into horizontal position.
