142STARTING AND OPERATING
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 experi -
enced due to uneven tire wear, low or uneven tire pres -
sures, 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 TO 4L OR 4L TO 4H
With the vehicle rolling at 1 to 3 mph (2 to 5 km/h), shift an automatic transmission into NEUTRAL (N), or press the
clutch pedal on a manual transmission. While the vehicle
is coasting at 1 to 3 mph (2 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 transmission into DRIVE
or release the clutch pedal on a manual transmission.
NOTE:Shifting into or out of 4L is possible with the vehicle
completely stopped; however, difficulty may occur due to
the mating teeth not being properly aligned. Several
attempts may be required for clutch teeth alignment and
shift completion to occur. The preferred method is with the vehicle rolling at 1 to 3 mph (2 to 5 km/h). Avoid
attempting to engage or disengage 4L with the vehicle
moving faster than 1 to 3 mph (2 to 5 km/h).
During cold weather, you may experience increased effort
in shifting until the transfer case fluid warms up. This is
normal.
FIVE-POSITION TRANSFER CASE —
I
F EQUIPPED

Four-Wheel Drive Gear Selector

The transfer case provides five mode positions:
 2H — Two-Wheel Drive High Range
 4H AUTO — Four-Wheel Drive Auto High Range
 4H PART TIME — Four-Wheel Drive Part Time High
Range
 N (Neutral)
 4L — Four-Wheel Drive Low Range
For additional information on the appropriate use of each
transfer case mode 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 AUTO
Four-Wheel Drive Auto High Range — This range sends
power to the front wheels. The four-wheel drive system will
be automatically engaged when the vehicle senses a loss
of traction. Additional traction for varying road conditions.
4H PART TIME
Four-Wheel Drive Part Time 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.
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.

23_JL_OM_EN_USC_t.book Page 142

STARTING AND OPERATING143
N (Neutral)
Neutral — This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat towing
behind another vehicle
Úpage 176.
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.
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
Úpage 143.
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.
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 experi -
enced due to uneven tire wear, low or uneven tire pres -
sures, 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.
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.

144STARTING AND OPERATING
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
an automatic transmission into NEUTRAL (N), or press the
clutch pedal on a manual transmission. While the vehicle
is coasting at 1 to 3 mph (2 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 transmission into DRIVE
or release the clutch pedal on a manual transmission.
NOTE:Shifting into or out of 4L is possible with the vehicle
completely stopped; however, difficulty may occur due to
the mating teeth not being properly aligned. Several
attempts may be required for clutch teeth alignment and
shift completion to occur. The preferred method is with the
vehicle rolling at 1 to 3 mph (2 to 5 km/h). Avoid attempting to engage or disengage 4L with the vehicle
moving faster than 1 to 3 mph (2 to 5 km/h).
TRAC-LOK REAR AXLE — IF EQUIPPED
The Trac-Lok rear axle provides a constant driving force to
both rear wheels and reduces wheel spin caused by the
loss of traction at one driving wheel. If traction differs
between the two rear wheels, the differential automatically proportions the usable torque by providing
more torque to the wheel that has traction.
Trac-Lok is especially helpful during slippery driving
conditions. With both rear wheels on a slippery surface, a
slight application of the accelerator will supply maximum
traction.
AXLE LOCK (TRU-LOK) FRONT AND
R
EAR — IF EQUIPPED
The AXLE LOCK switch is located on the instrument panel
(to the right of the steering column).

Axle Lock Switch Panel

This feature will only activate when the following
conditions are met:

ELECTRO-HYDRAULIC POWER STEERING
Your vehicle is equipped with an Electro-Hydraulic Power
Steering system that provides increased vehicle response
and ease of maneuverability. The system adapts to
different driving conditions. If the Electro-Hydraulic Power
Steering system experiences a fault that prevents it from
providing power steering assist, then the system will
provide mechanical steering capability.
WARNING!

If the stabilizer/sway bar will not return to on-road mode,
the Sway Bar Indicator Light will flash in the instrument
cluster and vehicle stability may be reduced. Do not
attempt to drive the vehicle over 18 mph (29 km/h).
Driving faster than 18 mph (29 km/h) with a discon -
nected stabilizer/sway bar may contribute to the loss of
vehicle control, which could result in serious injury.

CAUTION!
Extreme steering maneuvers may cause the electrically
driven pump to reduce or stop power steering
assistance in order to prevent damage to the system.
Normal operation will resume once the system is
allowed to cool.

23_JL_OM_EN_USC_t.book Page 146

STARTING AND OPERATING147
If the “SERVICE POWER STEERING” message and a
flashing icon are displayed on the instrument cluster
screen, it indicates that the vehicle needs to be taken to
an authorized dealer for service. It is likely the vehicle has
lost power steering assistance
Úpage 108.
If the “POWER STEERING HOT” message and an icon are
displayed on the instrument cluster screen, it indicates
that extreme steering maneuvers may have occurred,
which caused an over temperature condition in the power
steering system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, pull over
and let vehicle idle for a few moments until the light turns
off
Úpage 108.
NOTE:
 Even if power steering assistance is no longer opera -
tional, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at very low vehicle speeds
and during parking maneuvers.
 If the condition persists, see an authorized dealer for
service.

Push the Adaptive Cruise Control (ACC) on/off button until
one of the following appears in the instrument cluster
display:
WARNING!
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver involve -
ment. It is always the driver’s responsibility to be
attentive of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle ahead and,
most importantly, brake operation to ensure safe
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a colli -
sion and death or serious personal injury.
 The ACC system:
 Does not react to pedestrians, oncoming vehi -
cles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
 Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.
 Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.On vehicles with an automatic transmission, will
bring the vehicle to a complete stop while
following a vehicle ahead and hold the vehicle
for two seconds in the stop position. If the
vehicle ahead does not start moving within two
seconds, the ACC system will display a message
that the system will release the brakes and that
the brakes must be applied manually. An
audible chime will sound when the brakes are
released.
 You should not utilize the ACC system:
 When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa-
tions (i.e., in highway construction zones).
 When entering a turn lane or highway off-ramp;
when driving on roads that are winding, icy,
snow-covered, slippery, or have steep uphill or
downhill slopes.
 When towing a trailer up or down steep slopes.
 When circumstances do not allow safe driving at
a constant speed.
