FORD 2004 Ranger v.2 - Manual (Page 36)

Parking
Before leaving the driver’s seat, make sure that the gearshift is engaged
in P (Park) with an automatic transmission or either 1 (First) or R
(Reverse) with a manual transmission. Set the parking brake fully, shut
off the ignition and remove the key.
Some 4WD vehicles include a Neutral mode. When the transfer case is in
the N (Neutral) position, the engine and transmission are disconnected
from the rest of the driveline. Therefore, the vehicle is free to roll even if
the automatic transmission is in P (Park) or the manual transmission is
in gear.
Do not leave the vehicle unattended with the transfer case in N
(Neutral) position. Always set the parking brake fully and turn
off the ignition when leaving the vehicle. If you do not follow these
precautions your vehicle may move unexpectedly and injure someone.
