Chevrolet 1993 S-10 Pickup Owner's Manual page 209

Before towing you should:
1. Set the parking brake firmly.
2. Place the auto'matic transmission in P (Park) or the manual transmission
in th:e lowest gear (1 st gear).
3. Firmly attach the vehicle being towed to the tow vehicle. Refer to the
hitch manufacturer's instructions.
Shifting the transfer case to N (Neutral) can cause your vehicle to
roll even if the transmission
is
in P (Park), for an automatic
transmission, or if your vehicle is in gear, for a manual transmission.
This is because the transfer case overrides the transmission.
