yellowblue 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 your front axle to give you extra power and also gives you a higher driveline ratio. It should be used only for off-road driving. You can shift from 2-Wheel High (2H) to 4-Wheel High (4H) or from 4-Wheel High (4H) to 2-Wheel High (2H) while the vehicle is moving. Your front axle will engage faster if you take your foot off the accelerator for a few seconds after you shift. In extremely cold weather, it may be necessary to stop or slow the vehicle to shift into 4-Wheel High (4H). To shift into or out of 4-Wheel Low (4L) or NEUTRAL (N): 1. Slow the vehicle to a roll, about 1 to 3 mph (2 to 5 km/h) and shift the transmission into NEUTRAL (N). 2. Shift the transfer case shift lever in one continuous motion. Don't pause in NEUTRAL (N) as you shift the transfer case into 4-Wheel Low (4L), or your 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 your tires to wear faster and make your transfer case harder to shift and run noisier. When your headlamps or parking lamps are on, rotate the thumbwheel next to the headlamp switch up to brighten or down to dim your transfer case indicator light. 2-21
