Head Restraints - GMC Sierra 2008 Owner's Manual

Power Reclining Seatbacks
If the seats have power reclining seatbacks, the control
used to recline them is located on the outboard side
of the seat behind the power seat control.
•
To recline the seatback, tilt the top of the
control rearward.
•
To bring the seatback forward, tilt the top of the
control forward.
Do not have a seatback reclined if your vehicle
is moving.

Head Restraints

Adjust the head restraint so that the top of the restraint
is at the same height as the top of the occupant's
head. This position reduces the chance of a neck
injury in a crash.
