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

the ignition switch is turned to the OFF position.
The Axle Lock disengages at speeds above 30 mph
(48 km/h), and will automatically re-lock once vehicle
speed is less than 10 mph (16 km/h).
AXLE LOCK (TRU-LOK) REAR ONLY —
I
F EQUIPPED
The rear axle may be locked in 4H if the proper conditions
are met.
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.
WARNING!

rear locker under some conditions.
If this occurs, the rear axle will automatically re-lock as
soon as the system allows.
ELECTRONIC SWAY BAR DISCONNECT —
I
F EQUIPPED
Your vehicle may be equipped with an electronic
disconnecting stabilizer/sway bar. This system allows
greater front suspension travel in off-road situations.
This system is controlled by the SWAY BAR switch located
on the instrument panel (to the right of the steering
column).
SWAY BAR Switch
Push the SWAY BAR switch to activate the system. Push
the switch again to deactivate the system. The Sway Bar
Indicator Light (located in the instrument cluster) will
illuminate when the bar is disconnected. The Sway Bar
Indicator Light will flash during activation transition, or when activation conditions are not met. The stabilizer/
sway bar should remain in on-road mode during normal
driving conditions.
To disconnect the stabilizer/sway bar, shift to either 4H or
4L and push the SWAY BAR switch to obtain the off-road
position
Úpage 140. The Sway Bar Indicator Light will
flash until the stabilizer/sway bar has been fully
disconnected.
NOTE:The stabilizer/sway bar may be torque locked due to left
and right suspension height differences. This condition is
due to driving surface differences or vehicle loading. In
order for the stabilizer/sway bar to disconnect/reconnect,
the right and left halves of the bar must be aligned. This
alignment may require that the vehicle be driven onto level
ground or rocked from side to side.
WARNING!
Ensure the stabilizer/sway bar is reconnected before
driving on hard surfaced roads or at speeds above
18 mph (29 km/h); a disconnected stabilizer/sway bar may contribute to the loss of vehicle control, which
could result in serious injury. Under certain
circumstances, the front stabilizer/sway bar enhances
vehicle stability and assists with vehicle control. The
system monitors vehicle speed and will attempt to
reconnect the stabilizer/sway bar at speeds over
18 mph (29 km/h). This is indicated by a flashing or solid Sway Bar Indicator Light. Once vehicle speed is
reduced below 14 mph (22 km/h), the system will once
again attempt to return to off-road mode.

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

Wait five seconds before removing the fuel nozzle
to allow excess fuel to drain from the nozzle.
5. Remove the fuel nozzle, reinstall fuel cap and close fuel filler door.
NOTE:Tighten the fuel filler cap about a quarter turn until you
hear one click. This is an indication that the cap is properly
tightened.
AVOID USING CONTAMINATED FUEL
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper
maintenance of the engine fuel filter and fuel tank is
essential see
Úpage 321.
BULK FUEL STORAGE — DIESEL FUEL
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with water
will promote the growth of “microbes.” These microbes
form “slime” that will clog the fuel filtration system and
lines. Drain condensation from the supply tank and
change the line filter on a regular basis.
NOTE:When a diesel engine is allowed to run out of fuel, air is
pulled into the fuel system.
If the vehicle will not start see
Úpage 323.
DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic
Reduction (SCR) system to meet the very stringent diesel
emissions standards required by the Environmental
Protection Agency.
The purpose of the SCR system is to reduce levels of NOx
(oxides of nitrogen emitted from engines) that are harmful
to our health and the environment to a near-zero level. A
small quantity of Diesel Exhaust Fluid (DEF) is injected into
the exhaust upstream of a catalyst where, when
vaporized, it converts smog-forming nitrogen oxides (NOx)
into harmless nitrogen (N2) and water vapor (H2O), two
natural components of the air we breathe. You can
operate with the comfort that your vehicle is contributing
to a cleaner, healthier world environment for this and
generations to come.
1 — Diesel Fuel Filler
2 — DEF Filler
CAUTION!
For diesel engines, only use diesel fuel for motor
vehicles in accordance with ASTM D-975 Grade S15
specifications. The use of other products or mixtures
may damage the engine beyond repair and
consequently void the warranty, due to the damage
caused. If you accidentally introduce other types of fuel
into the tank, do not start the engine. Empty the tank. If
the engine has been run for even an extremely limited
amount of time, you must not only drain the fuel tank,
but the rest of the supply circuit as well.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.

TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
Weight Distribution
Consider the following items when computing the weight
on the rear axle of the vehicle:
The tongue weight of the trailer.
The weight of any other type of cargo or equipment put
in or on your vehicle.
The weight of the driver and all passengers.
NOTE:Remember that everything put into or on the trailer adds
to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the Tire And Loading Information Placard for the
maximum combined weight of occupants and cargo for
your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended:
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
Make certain that the load is secured in the trailer
and that it will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
When hauling cargo, or towing a trailer, do not over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance, or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, chassis structure, or tires.
Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross
the chains under the trailer tongue and allow enough
slack for turning corners.
Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. Always block or "chock" the trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch utilized
CAUTION!
Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!
