CHEVROLET Tahoe - Manual (Page 162)

{ CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to
roll, even if the shift lever is in PARK (P).
So, be sure the transfer case is in a drive
gear — not in NEUTRAL. Always set the
parking brake.
Follow the proper steps to be sure your vehicle
will not move. See Shifting Into Park (P) on
page 157.
If you are pulling a trailer, see Towing a Trailer on
page 422.
