FORD 2013 F-550 v.3 - Manual (Page 213)

• Move the transfer case lever from 4H (4x4 High) to 2H (2WD) at a stop
or a vehicle speed below 3 mph (5 km/h), then disengage the locking
hubs (optional) by rotating the hub lock control from LOCK to FREE.
• For proper operation, make sure that both indicator arrows on the
hub are aligned, and that both hubs are set to either FREE or LOCK.
Shifting to/from 4L (4x4 Low)
1. Bring the vehicle to a stop or a speed below 3 mph (5 km/h).
2. Place the transmission in N (Neutral).
3. Move the transfer case shift lever through N (Neutral) directly to the
desired position.
4. If the transfer case does not, or only partially moves to the desired
position, perform a shift with the transmission in N (Neutral) and the
vehicle rolling at a speed below 3 mph (5 km/h).
5. If shifting to 2H (2WD) with the vehicle at a complete stop, disengage
the locking hubs (optional) by rotating the hub lock control from LOCK
to FREE.
Using the N (Neutral) position
WARNING: Do not leave the vehicle unattended with the
transfer case in the N (Neutral) position. Always set the parking
brake fully and turn off the ignition when leaving the vehicle.
The transfer case neutral position
overrides the transmission and puts
the vehicle in neutral regardless of
transmission gearshift lever position.
The vehicle can move forward or
backwards.
This position should only be used
when towing the vehicle.
