Driving Shifting to A4WD Move the 4WD control back to A4WD at a stop or at speeds up to 88 km/h (55 mph). A4WD 4H 4L 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 (except models equipped with Auto 4WD). This may damage the drivelines and axles. 169
