Four-Wheel Drive (If Equipped) 221 Using the Electronic Shift on the Fly 4WD system (If Equipped) 2H (4X2) - Delivers power to the 2H rear wheels only. This mode is 4H appropriate for normal on-road 4L driving and provides the best fuel economy and smoothness. 4H (4X4 HIGH) - provides mechanically locked four-wheel drive power to the front and rear wheels. This position is not recommended for use on dry pavement. This position is only intended for off-road or winter conditions, such as deep snow, ice or shallow sand. Note: Do not use 4H (4X4 HIGH) on dry, hard surfaced roads. Doing so can produce excessive noise and increased tire wear. 4H (4X4 HIGH) is only intended for consistently slippery or loose surfaces. 4L (4X4 LOW) - Provides mechanically locked four-wheel drive when extra power at reduced speeds is required. This position is not recommended for use on dry pavement. Use this position for off-road low-speed operation or when extra power is required, such as climbing steep grades, going through deep sand or pulling a boat out of the water. 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. 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. 2013 F-150 (f12) Owners Guide gf, 3rd Printing, February 2013 USA (fus)
