Four-Wheel Drive (If Equipped) 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 or from 4L (4x4 low) for proper operation. Note: Do not use 4L (4X4 LOW) on dry, hard surfaced roads. Doing so can produce excessive noise and increased tire wear. 4L (4X4 LOW) is only intended for consistently slippery or loose surfaces. Use of 4L (4X4 LOW) on these surfaces may produce some noise (such as occasional clunks), but will not damage drive components. Note: The AdvanceTrac system has the ability to take over control of the transfer case clutch and disable it during driving maneuvers when necessary. Shifting between system modes Note: Momentarily releasing the accelerator pedal while performing a shift will improve engagement/disengagement times. 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. Shifting to or from 4L (4X4 low) Note: Some noise may be heard as the system shifts or engages; this is normal. 152 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. If SHIFT DELAYED PULL FORWARD displays in the information display, a transfer case gear tooth blockage is present. To alleviate this condition, place the transmission in a forward gear, move your vehicle forward approximately 5 feet (1.5 meters), and shift the transmission back to N neutral to allow the transfer case to complete the range shift. Using the 2-Speed Automatic 4WD System (If Equipped) This system includes an electronically controlled transfer case with a high capacity clutch. The system is interactive with the road, continually monitoring and adjusting torque delivery to the front and rear wheels to optimize traction. Note: The AdvanceTrac system has the ability to take over control of the transfer case clutch and disable it during driving maneuvers when necessary. F150 (TF6)
