Head Restraints - Hummer 2003 H2 Owner's Manual

CAUTION:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts can't do their job when
you're reclined like this.
The shoulder belt can't do its job. In a crash, you
could go into it, receiving neck or other injuries.
The lap belt can't do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt
properly.

Head Restraints

Adjust your head restraint so that the top of the restraint
is closest to the top of your head. This position reduces
the chance of a neck injury in a crash.
