In the event that additional traction is required,
the transfer case 4H 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 and 4L posi-
tions are intended for loose, slippery road sur-
faces only and not intended for normal driving.
Driving in the 4H and 4L positions on hard-
surfaced roads will cause increased tire wear and
damage to the driveline components. Refer to
“Shifting Procedures” in this section for further
information on shifting into 4H or 4L.
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
positions at a given road speed. Take care not to
overspeed the engine.
2H to 4H or 4H to 2H
Shifting between 2H and 4H can be made with
the vehicle stopped or in motion. With the
vehicle in motion, the transfer case will engage/
disengage faster if you momentarily release the
accelerator pedal after completing the shift.
Apply a constant force when shifting the trans-
fer case lever.
4H to 4L or 4L to 4H
With the vehicle rolling at 2 to 3 mph (3 to
5 km/h), shift an automatic transmission into
NEUTRAL (N), or press the clutch pedal on a
manual transmission. While the vehicle is coast-
ing at 2 to 3 mph (3 to 5 km/h), shift the transfer
case lever firmly to the desired position. Do not
pause with the transfer case in N (Neutral). Once
the shift is completed, place the automatic trans-
mission into DRIVE or release the clutch pedal on
a manual transmission.
