Operating Instructions/Precautions
The transfer case provides four mode positions two
(rear) wheel drive high range, four wheel drive high
range, neutral, and four wheel drive low range.
This transfer case is intended to be driven in the two
wheel drive (2H) position for normal street and highway
conditions such as dry hard surfaced roads.
In the events when additional traction is required, the
transfer case 4H and 4L positions can be used to lock the
front and rear driveshafts together and force the front
and rear wheels to rotate at the same speed. This is
accomplished by simply moving the shift lever to these
positions. The 4H and 4L positions are intended for loose,
slippery road surfaces only. Driving in the 4H and 4L
positions on dry hard surfaced roads may cause in-
creased tire wear and damage to the driveline compo-
nents.
The 4WD indicator light, located in the instrument panel,
alerts the driver that the vehicle is in four wheel drive
and that the front and rear driveshafts are locked to-
gether. This light illuminates when the transfer case is
shifted to either the 4H or 4L positions.
NOTE: Do not attempt to make a shift while only the
front or rear wheels are spinning. The transfer case is not
equipped with a synchronizer and therefore the front and
rear driveshafts speeds must be equal for the shift to take
place. Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.
When operating your vehicle in 4L, the engine speed is
approximately three times that of the 2H or 4H positions
at a given road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).
