Seatback Latches - GMC 2001 Sierra 1500 Pickup Owner's Manual

On some models, the head restraints tilt forward and
rearward also.
To tilt the head restraints forward, grasp the top of the
restraint and move it forward to where you want it to go
until you hear a click. It will then be locked into that
position until you need to move it again. Pulling it
forward past the last position will allow the restraint to
return to its upright position.

CAUTION:
If the seatback isn't locked, it could move forward
in a sudden stop or crash. That could cause injury
to the person sitting there. Always press rearward
on the seatback to be sure it is locked.

The seatbacks fold forward to let you access the rear
of the cab.
To return the seatback to the upright position, push the
seatback rearward until it latches. After returning the
seatback to its upright position, try to pull the seatback
forward to make sure it is locked.
To fold a front seatback
forward, pull this lever
toward the front of the
vehicle to release the
seatback. The lever is
located on the outboard
side of the seat cushion.
