STARTING AND OPERATING 155
The transfer case provides four mode positions:
2H (2WD High) — Two-Wheel Drive High
Range
4H (4WD High) —Four-Wheel Drive High
Range
N (Neutral)
4L (4WD Low) — Four-Wheel Drive Low Range
For additional information on the appropriate
use of each transfer case mode position, see
the information below:
2WD High
Two-Wheel Drive High Range — This range is for
normal street and highway driving on dry, hard
surfaced roads.
4WD High
Four-Wheel Drive High Range — This range
maximizes torque to the front driveshaft, forcing
the front and rear wheels to rotate at the same
speed. This range provides additional traction
for loose, slippery road surfaces only.
N (Neutral)
N (Neutral) — This range disengages both the
front and rear driveshafts from the powertrain.
To be used for flat towing behind another
vehicle Ú page 199.
4WD Low
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).
The transfer case is intended to be driven in the
2WD High position for normal street and
highway conditions, such as hard-surfaced
roads.
In the event that additional traction is required,
the transfer case 4WD High and 4WD Low
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 4WD
High and 4WD Low positions are intended for
loose, slippery road surfaces only and not
intended for normal driving. Driving in the 4WD
High and 4WD Low 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 4WD High or 4WD
Low.
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 4WD High position.
When operating your vehicle in 4WD Low, the
engine speed will be approximately three times
(four times for Rubicon models) that of the 2WD
High or 4WD High positions at a given road
speed. Take care not to overspeed the engine.
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 power-
train, 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.
