Driving Using a manual 4WD system (if equipped) 2H 4H N 4L 2H (2WD High) - Power to the rear wheels only; used for street and highway driving. Provides optimal smoothness and fuel economy at high speeds. 4H (4WD High) - Used for extra traction such as in snow or icy roads or in off-road situations. Not intended for use on dry pavement. N (Neutral) - No power to either front or rear wheels. 4L (4WD 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 (4WD 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 (4WD Low) for proper operation. Shifting between 2H (2WD high) and 4H (4WD high) • Move the transfer case lever between 2H (2WD High) and 4H (4WD High) at a stop or any forward speed up to 55 mph (88 km/h). 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 (4WD Low) 1. Bring the vehicle to a complete stop. 2. Place the transmission in N (Neutral). 3. Move the transfer case lever through N (Neutral) directly to the desired position. • If the transfer case will not engage into 4L (4WD Low), allow the vehicle to coast at a speed below 3 mph (5 km/h), then repeat Steps 2 and 3. 283 2008 F-150 (f12) Owners Guide (post-2002-fmt) USA (fus)
