Buick 2007 Rainier - Manual (Page 15)

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.
Pull the head restraint
up to raise it.
To lower the head restraint, press the button,
located on the top of the seatback, and push the
head restraint down.
