172 STARTING AND OPERATING
N (Neutral)
Neutral — This range disengages both the front and
rear driveshafts from the powertrain. To be used
for flat towing behind another vehicle Ú page 217.
4L
Four-Wheel Drive Low Range — This range provides
low speed four-wheel drive. It maximizes torque to
the front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This range
provides additional traction and maximum pulling
power for loose, slippery road surfaces only. Do not
exceed 25 mph (40 km/h).
This transfer case is designed to be driven in the
two-wheel drive position (2H) or four-wheel drive
position (4H AUTO) for normal street and highway
conditions on dry hard surfaced roads. Driving the
vehicle in 2H will have greater fuel economy
benefits as the front axle is not engaged in 2H.
For variable driving conditions, the 4H AUTO mode
can be used. In this mode, the front axle is
engaged, but the vehicle's power is sent to the rear
wheels. Four-wheel drive will be automatically
engaged when the vehicle senses a loss of
traction. Because the front axle is engaged, this
mode will result in lower fuel economy than the 2H
mode.
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 positions are intended for
loose, slippery road surfaces 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. For further information on shifting
into 4H or 4L Ú page 172.
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 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 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.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (Neutral) position without first fully
engaging the parking brake. The transfer case N
(Neutral) position disengages both the front and
rear driveshafts from the powertrain, and will
allow the vehicle to roll, even if the automatic
transmission is in PARK (or manual transmission
is in gear). The parking brake should always be
applied when the driver is not in the vehicle.
