Driving 4H (Lock) - The "4X4 HI" light will illuminate in the instrument cluster when this position is selected. This position is not recommended for use on dry pavement. This position is only intended for severe winter or off-road conditions, such as deep snow, ice or deep sand. Shifting between AWD (Auto) and 4H (Lock) Move the control from AWD to 4H at a stop or while driving at any speed. Driving off-road with truck and utility vehicles 4WD vehicles are specially equipped for driving on sand, snow, mud and rough terrain and have operating characteristics that are somewhat different from conventional vehicles, both on and off the road. How your vehicle differs from other vehicles Truck and utility vehicles can differ from some other vehicles. Your vehicle may be higher to allow it to travel over rough terrain without getting hung up or damaging underbody components. The differences that make your vehicle so versatile also make it handle differently than an ordinary passenger car. Maintain steering wheel control at all times, especially in rough terrain. Since sudden changes in terrain can result in abrupt steering wheel motion, make sure you grip the steering wheel from the outside. Do not grip the spokes. Drive cautiously to avoid vehicle damage from concealed objects such as rocks and stumps. You should either know the terrain or examine maps of the area before driving. Map out your route before driving in the area. To maintain steering and braking control of your vehicle, you must have all four wheels on the ground and they must be rolling, not sliding or spinning. Basic operating principles • Do not use 4WD on dry, hard surfaced roads. Doing so will produce excessive noise, increase tire wear and may damage drive components. 4WD modes are only intended for consistently slippery or loose surfaces. • Drive slower in strong crosswinds which can affect the normal steering characteristics of your vehicle. • Be extremely careful when driving on pavement made slippery by loose sand, water, gravel, snow or ice. 286 2008 F-150 (f12) Owners Guide (post-2002-fmt) USA (fus)
