When Using the Manual Transfer Case • Shifting should be made using quick motions. Shifting slowly may make it more difficult to shift. 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. • 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. • Shift the transfer case lever in one continuous motion into either the Four-Wheel-Drive High or Two-Wheel-Drive High position. • While in Four-Wheel High or Four-Wheel-Drive Low you may experience reduced fuel economy. • Avoid driving in Four-Wheel Drive on clean, dry pavement. It may cause your tires to wear faster, make the transfer case harder to shift, and run noisier. • In extremely cold weather, it may be necessary to slow or stop the vehicle to shift into Four-Wheel-Drive High until the vehicle has warmed up. • If the transfer case shifter is in the N (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 N (Neutral). This will realign the gear teeth in the transfer case and allow you to complete the shift. • While in Four-Wheel-Drive High, the vehicle can be driven at any posted legal speed limit. 2-39
