An indicator light near the lever shows you the transfer case settings: 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 for extended periods of time. 4L (Four-Wheel Low): This setting also engages your front axle and delivers extra torque. You may never need 4L. It sends maximum power to all four wheels. You might choose 4L if you are driving off-road in deep sand, deep mud, deep snow, and while climbing or descending steep hills. When operating in Four-Wheel Low, the gear ratio provides additional torque when compared to four-wheel high. The transmission gear shift feel will be exaggerated. CAUTION: (Continued) 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 2-49. N (Neutral): Shift to this setting only when your vehicle needs to be towed. See Recreational Vehicle Towing on page 4-62 or Towing Your Vehicle on page 4-61. 2H (Two-Wheel High): This setting is used for driving in most street and highway situations. Your front axle is not engaged in two-wheel drive. This setting also provides the best fuel economy. 4H (Four-Wheel 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 your 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 high to 2H while the vehicle is moving. Your 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 four-wheel high. {CAUTION: Shifting the transfer case to NEUTRAL can cause your vehicle to roll even if the transmission is in PARK (P), or if you have a manual transmission, even if you are in gear.
