CAUTION:
Four-wheel drive vehicles with the transfer
case in NEUTRAL will allow the vehicle to roll,
even if the automatic transmission 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) (Automatic
Transmission) on page 2-34.
If you are pulling a trailer, see Towing a Trailer on
page 4-44.
