When Using the Manual Transfer Case • Shifting should be made using quick motions. Shifting slowly may make it more difficult to shift. • In extremely cold weather, it may be necessary to slow or stop the vehicle to shift into four-wheel high until your vehicle has warmed up. • 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, your vehicle can be driven at any posted legal speed limit. Shifting In or Out of 4L (Four-Wheel Low) Notice: Shifting the transfer case into 4L while moving at speeds faster than 3 mph (5 km/h) may cause premature wear to the transfer case, and may cause the gears to grind. To avoid causing premature wear, and grinding the gears, do not shift the transfer case into 4L while the vehicle is moving faster than 3 mph (5 km/h). Shifts into 4L can be made with the vehicle at a stop, or while slowly rolling about 1 to 3 mph (2 to 5 km/h). • While in 4H or 4L you may experience reduced fuel economy. • Avoid driving in four-wheel drive on clean, dry pavement. It may cause your tires to wear faster, and make your transfer case harder to shift and run noisier. Shifting from 2H (Two-Wheel High) to 4H (Four-Wheel High) • Shifts between 2H and 4H can be made at any vehicle speed. • Shift the automatic transmission into NEUTRAL (N), or with a manual transmission, press the clutch pedal, or shift into NEUTRAL (N). • It is easiest to shift the transfer case when maintaining a constant speed or a slight acceleration. If possible, avoid shifting while slowing down, as it will may make it harder to shift. • Shift the transfer case shift lever in one continuous motion into the 4L position. • Shift your transfer case lever in one continuous motion into either the 4H or 2H position. • When in 4L do not drive faster than 45 mph. This will reduce wear and extend the life of your transfer case. 2-39
