Four-Wheel Drive (If Equipped) Shifting between system modes Note: Do not perform these operations if the rear wheels are slipping. Note: Some noise may be heard as the 4x4 system shifts or engages. This is normal. In order to reduce engagement noise, it is recommended that all shifts be performed at speeds below 3 mph (5 km/h). Note: The vehicle should not be driven in 4X4 High with the hub locks disengaged as this condition may damage driveline system components. Engage the locking hubs by rotating the hub lock control from FREE to LOCK, then move the transfer case lever from 2H (2WD) to 4H (4x4 High) at a stop or a vehicle speed below 3 mph (5 km/h). 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). E163189 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. 155 Super Duty (), enUSA
