Driving Using the electronic shift 4WD system (if equipped) 2H (4X2 High) - Power to the rear wheels only; 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. 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 2H (4X2 High) and 4H (4X4 High) • Move the 4WD control between 2H (4X2 High) and 4H (4X4 High) at any forward speed. The message center will display 4X4 SHIFT IN PROGRESS during the system shift. "4X4 HIGH" will display in the message center. Note: Momentarily releasing the accelerator pedal while preforming 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. Shifting to/from 4L (4X4 Low) 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. 299 2009 F-150 (f12) Owners Guide (own2002), 3rd Printing USA (fus)
