You can shift from Two-Wheel-Drive High to Four-Wheel-Drive High or Four-Wheel-Drive High to Two-Wheel-Drive High while the vehicle is moving. In extremely cold weather, it may be necessary to stop or slow the vehicle to shift into Four-Wheel-Drive High. Shifting from Two-Wheel-Drive High to Four-Wheel-Drive High • Shifts between Two-Wheel-Drive High and Four-Wheel-Drive High can be made at any vehicle speed. When Using the Manual Transfer Case • Shifting should be made using quick motions. Shifting slowly may make it more difficult to shift. • Shift the transfer case lever in one continuous motion into either the Four-Wheel-Drive High or Two-Wheel-Drive High position. • 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. • In extremely cold weather, it may be necessary to slow or stop the vehicle to shift into Four-wheel-Drive High until your vehicle has warmed up. • While in Four-Wheel High or Four-Wheel-Drive Low you may experience reduced fuel economy. • While in Four-Wheel-Drive High, your vehicle can be driven at any posted legal speed limit. • Avoid driving in Four-Wheel Drive on clean, dry pavement. It may cause your tires to wear faster, and make the transfer case harder to shift and run noisier. • If the transfer case shifter is in the NEUTRAL position and you have difficulty reaching the selected transfer case mode, with the engine running, shift the transmission momentarily to drive and then back to NEUTRAL. This will realign the gear teeth in the transfer case and allow you to complete the shift. 2-39
