2H (Two-Wheel Drive High): This setting is used for driving in most street and highway situations. The front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. 4H (Four-Wheel Drive High): Use this setting when you need extra traction, such as on snowy or icy roads or in most off-road situations. This setting also engages the front axle to help drive your vehicle. This is the best setting to use when plowing snow. You can shift from 2H to 4H or 4H to 2H while the vehicle is moving. The front axle will engage faster if you take your foot off of the accelerator for a couple of seconds after you shift. In extremely cold weather, it may be necessary to stop or slow the vehicle to shift into 4H. When Using the Manual Transfer Case • Shifting should be made using quick motions. Shifting slowly may make it more difficult to shift. • You may notice that it is harder to shift when the vehicle is cold. After the vehicle warms up the shifting will return to normal. • While in 4H or 4L you may experience reduced fuel economy. • Avoid driving in four-wheel drive on clean, dry pavement. Doing this may cause the tires to wear faster, and make your transfer case harder to shift, and run noisier. Shifting from 2H (Two-Wheel Drive High) to 4H (Four-Wheel Drive High) • Shifts between 2H and 4H can be made at any vehicle speed. • It is easiest to shift the transfer case when maintaining a constant speed or during a slight acceleration. If possible, avoid shifting while slowing down, as it will make it harder to shift. 156
