Four-Wheel Drive (If Equipped) Using the Electronic Shift on the Fly 4WD system (If Equipped) Note: Do not perform this operation if the rear wheels are slipping. Note: Some noise may be heard as the system shifts or engages; this is normal. Note: 4X4 high mode is not intended for use on dry pavement. You can move the control from 2H or 4H at a stop or while driving. The information display may display a message indicating a 4X4 shift is in progress. Once the shift is complete the message center will then display the system mode selected. E163190 2H (2WD) For general on-road driving. Sends power to the rear wheels only and should be used for street and highway driving. Provides optimal smoothness and fuel economy at high speeds. 4H (4X4 HIGH) Used for extra traction such as in snow or icy roads or in off road situations. This mode is not intended for use on dry pavement. 4L (4X4 LOW) Uses extra gearing to provide maximum power to all four wheels at reduced speeds. Intended only for off-road applications such as deep sand, steep grades, or pulling heavy objects. 4L (4x4 low) will not engage while the vehicle is moving above 3 mph (5 km/h); this is normal and should be no reason for concern. Refer to Shifting to/from 4L (4x4 low) for proper operation. Shifting between system modes Note: Momentarily releasing the accelerator pedal while performing a shift will improve engagement/disengagement times. If SHIFT DELAYED PULL FORWARD is displayed in the information display during the mode shift, transfer case gear tooth blockage is present. To alleviate this condition, place the transmission in a forward gear and move the vehicle forward approximately 5 feet (1.5 meters) to allow the transfer case to complete the mode shift. Shifting to/from 4L (4X4 low) Note: Some noise may be heard as the system shifts or engages; this is normal. Note: 4x4 low mode is not intended for use on dry pavement. 1. Bring the vehicle to a speed of 3 mph (5 km/h) or less. 2. Place the transmission in N (Neutral). 3. Move the 4WD control to the desired position. The information display will display a message indicating a 4X4 shift is in progress. The information display will then display the system mode selected. If any of the above shift conditions are not met, the shift will not occur and the information display will display information guiding the driver through the proper shifting procedures. 156 Super Duty (), enUSA
