Shift Positions
For additional information on the appropriate use of each
transfer case mode position, see the information below:
4WD HI
This range is used on surfaces such as ice, snow, gravel,
sand, and dry hard pavement.
NEUTRAL
This range disengages both the front and rear driveshafts
from the powertrain. It is to be used for flat towing
behind another vehicle. Refer to “Recreational Towing”
in “Starting and Operating” for further information.
4WD LOW
This range is for low speed four-wheel drive. It locks the
front and rear driveshafts together and forces the front
and rear wheels to rotate at the same speed. It provides
additional traction and maximum pulling power for
loose, slippery road surfaces only. Do not exceed 25 mph
(40 km/h).
Shifting Procedures
4WD HI to 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition switch in the ON position or the engine running,
shift the transmission into NEUTRAL, and raise the
transfer case T-handle. The “4WD LOW” indicator light
in the instrument cluster will begin to flash and remain
on solid when the shift is complete. Release the T-handle. 5
