When Using the Manual Transfer Case

• Shifts into or out of Four-Wheel Drive Low or N (Neutral) should be made using quick motions to avoid excessive gear grinding.

Shifting slowly may make it more difficult to shift.

• 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 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.

• 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 D (Drive) and then back to N (Neutral). This will realign the gear teeth in the transfer case and allow you to complete the shift.
