STARTING AND OPERATING
FOUR–WHEEL DRIVE OPERATION
WARNING!
Failure to engage a transfer case position completely
can cause transfer case damage or loss of power and
vehicle control. You could have a collision. Do not
drive the vehicle unless the transfer case is fully
engaged.
FOUR-POSITION TRANSFER CASE —
IF EQUIPPED
Four-Wheel Drive Gear Selector
The transfer case provides four positions:
•
2H — Two-Wheel Drive High Range
•
4H — Four-Wheel Drive High Range
•
N (Neutral)
•
4L — Four-Wheel Drive Low Range
For additional information on the appropriate use of
each transfer case position, see the following:
2H
Two-Wheel Drive High Range — This range is for normal
street and highway driving on dry, hard surfaced roads.
4H
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 pro-
vides additional traction for loose, slippery road sur-
faces only.
N (Neutral)
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.
N (Neutral) — This range disengages both the front and
rear driveshafts from the powertrain. To be used for flat
towing behind another vehicle
page 169.
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).
The transfer case is intended to be driven in the 2H
position for normal street and highway conditions, such
as hard-surfaced roads.
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. Driv-
ing in the 4H and 4L positions on hard-surfaced roads
will cause increased tire wear and damage to the drive-
line components. For further information on shifting
into 4H or 4L
page 137.
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 Rubi-
con 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.
