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
cluster) alerts the driver that the vehicle is in four wheel
drive and that the front and rear driveshafts are locked
together. This light illuminates when the transfer case is
shifted into the 4H position.
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 (four times for Rubicon mod-
els) that of the 2H or 4H positions at a given road speed.
Take care not to overspeed the engine.
Proper operation of four wheel drive vehicles depends on
tires of equal size, type, and circumference on each
wheel. Any difference will adversely affect shifting and
cause damage to the transfer case.
Because four wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
