Four-Wheel Drive If your vehicle has four-wheel drive, you can send your engine's driving power to all four wheels for extra traction. To get the most satisfaction out of four-wheel drive, you must be familiar with its operation. Read the part that follows before using four-wheel drive. You should use two-wheel-drive high for most normal driving conditions. Notice: Driving on clean, dry pavement in four-wheel drive for an extended period of time may cause premature wear on your vehicle's powertrain. Do not drive on clean, dry pavement in four-wheel drive on pavement for extended periods of time. Use these buttons to shift into and out of four-wheel drive. You can choose from the following: 2m(Two-Wheel High): This setting is for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. N (Neutral): Shift the vehicle's transfer case to NEUTRAL only when towing your vehicle. {CAUTION: Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P). You or someone else could be seriously injured. Be sure to set the parking brake before placing the transfer case in NEUTRAL. See Parking Brake on page 2-29. The transfer case buttons are located to the right of the steering wheel on the instrument panel. 4m(Four-Wheel High): This setting engages your front axle to help drive your vehicle. Use four-wheel high when you need extra traction, such as on snowy or icy roads, or in most off-road situations. 4n(Four-Wheel Low): This setting also engages your front axle to give you extra traction. It sends the maximum power to all four wheels. You might choose four-wheel low if you were driving off-road in sand, mud or deep snow and climbing or descending steep hills. 2-26
