STARTING AND OPERATING 153
In the event that additional traction is required,
the transfer case 4H AUTO and 4L positions can
be used to lock the front and rear driveshafts
together, forcing the front and rear wheels to
rotate at the same speed. The 4H AUTO and 4L
positions are intended for loose, slippery road
surfaces only and not intended for normal
driving. Driving in the 4H AUTO and 4L positions
on hard-surfaced roads will cause increased tire
wear and damage to the driveline components

The instrument cluster alerts the driver that the
vehicle is in four-wheel drive, and the front and
rear driveshafts are locked together. The light
will illuminate when the transfer case is shifted
into the 4H AUTO position.
When operating your vehicle in 4L, the engine
speed will be approximately three times (four
times for Rubicon models) that of the 2H or 4H
AUTO 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.
Shifting Procedures
2H TO 4H AUTO OR 4H AUTO TO 2H
Shifting between 2H and 4H AUTO can be made
with the vehicle stopped or in motion. The
preferred shifting speed would be 0 to 45 mph
(72 km/h). With the vehicle in motion, the
transfer case will engage/disengage faster if you
momentarily release the accelerator pedal after
completing the shift. Do not accelerate while
shifting the transfer case. Apply a constant force
when shifting the transfer case lever.
2H/4H AUTO TO 4H PART TIME OR 4H PART
TIME TO 2H/4H AUTO
Shifting between 2H/4H AUTO to 4H PART TIME
can be made with the vehicle stopped or in
motion. The preferred shifting speed would be 0
to 45 mph (72 km/h). With the vehicle in
motion, the transfer case will engage/
disengage faster if you momentarily release the
accelerator pedal after completing the shift. Do
not accelerate while shifting the transfer case.
Apply a constant force when shifting the
transfer case lever.
NOTE:

Do not attempt to make a shift while only the
front or rear wheels are spinning. The front
and rear driveshaft 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.

Delayed shifts out of four-wheel drive may be
experienced due to uneven tire wear, low or
uneven tire pressures, excessive vehicle
loading, or cold temperatures.

Shifting effort will increase with speed, this is
normal.
During cold weather, you may experience
increased effort in shifting until the transfer
case fluid warms up. This is normal.
4H PART TIME/4H AUTO TO 4L OR 4L TO 4H
PART TIME/4H AUTO
With the vehicle rolling at 1 to 3 mph (2 to
5 km/h), shift the transmission into NEUTRAL
(N). While the vehicle is coasting at 1 to 3 mph
(2 to 5 km/h), shift the transfer case lever firmly
