An indicator near the lever shows you the transfer case settings: To shift into or out of 4-WHEEL LOW (4L) or N (NEUTRAL): 2-Wheel High (2H): This setting is for driving in most street andhighway situations. Your front axle is not engaged in two-wheel drive. 4-Wheel High (4H): This setting engagesyour front axle tohelp drive your vehicle. Use 4H when you need extra traction, such as on wet or icy roads, or in most off-road situations. 1. Slow the vehicle to a roll, about 1 to 3 mph (2 to5 km/h) and shift the transmission into NEUTRAL (N). 2. Shift the transfer case shift lever in one quick, continuous motion. Don't pause inN (NEUTRAL) as you shift the transfer case into 4-WHEEL LOW (4L),or the gears could clash. Remember that driving in 4-WHEEL HIGH (4H) or 4-WHEEL LOW (4L)may reduce fuel economy. Also, driving in four-wheel drive on dry pavement could cause yourtires to wear faster and make your transfer case harder to shift and run noisier. When your headlamps or parking lamps are on, rotate the thumb wheel next to the headlamp switch up to brighten, and down to dim your transfer case indicator light. Neutral (N): Shift to this setting only when your vehicle needs to be towed or when using a power take-off. 4-Wheel Low (4L): This setting also engages yourfront axle to give you extra power and higher driveline ratio. a This position shouldbe used only for off-road driving. You can shift from 2-WHEEL HIGH (2H) to 4-WHEEL HIGH (4H) or from 4-WHEELHIGH (4H) to 2-WHEEL HIGH (2H) while the vehicle is moving.
