NOTE: Dash mounted four wheel drive indicator lights are off when your vehicle is in neutral. To shift from N (Neutral) to either 4H or 4L, stop the vehicle and engage the parking brake. Place the automatic transmission into N (Neutral) or depress the clutch on manual transmission vehicles. Push the transfer case shift lever to the desired position. If it is difficult to shift into either 4H or 4L, it may be necessary to let the vehicle roll slightly and/or turn off the engine (particularly on vehicles equipped with automatic transmissions). Driving Off Road with 4-Wheel Drive Most vehicles with four-wheel drive are especially equipped for driving on sand, snow, mud, or rough terrain and have operating characteristics that are somewhat different from conventional vehicles, both off and on the road. The driving tips below will help you learn to use four-wheel drive. u Do not use 4WD LOW on dry, hard-surfaced roads. u Special maintenance procedures are necessary after operating with drive components in water. u Manual locking hubs must be in LOCK position before shifting into four-wheel drive. When using four-wheel drive, 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 rim from the outside. Do not grip the spokes. 172
