Hummer 2006 H2 - Manual (Page 115)

{ CAUTION:
Full-time four-wheel drive vehicles with the
transfer case in NEUTRAL will allow the
vehicle to roll, even if your shift lever is in
PARK (P). So, be sure the transfer case is in a
drive gear — not in NEUTRAL. Always set your
parking brake.
Follow the proper steps to be sure your vehicle will not
move. See Shifting Into Park (P) on page 2-35.
If you are pulling a trailer, see Towing a Trailer on
page 4-63.
