LOWERING THE SOFT TOP INTO
S
UNRIDER® POSITION
Use this QR code to access your digital
experience. If the temperature is below 72°F (24°C) and/or the top
has been folded down for a period of time, the top will
appear to have shrunk when you raise it, making it difficult
to put up. This is caused by a natural contraction of the
vinyl or acrylic materials of the fabric top.
Place the vehicle in a warm area. Pull steadily on the top
fabric. The vinyl will stretch back to its original size and the
top can then be installed.
If the temperature is 41°F (5°C)
or below, do not attempt to put the top down or roll the
rear or side curtains.
WARNING!
 The fabric quarter windows and fabric top are
designed only for protection against the elements.
Do not rely on them to contain occupants within the
vehicle or to protect against injury during an acci -
dent. Remember, always wear seat belts.
 Make sure hands and fingers are clear of all pinch
points when installing and removing the soft tops.
The lift assist mechanism and side bows may cause
serious injury if fingers or hands get caught in
between.
CAUTION!
The soft top is not designed to carry any additional
loads such as roof racks, spare tires, building, hunting,
or camping supplies, and/or luggage, etc. Also, it was
not designed as a structural member of the vehicle
and, thus, cannot properly carry any additional loads
other than environmental (rain, snow, etc.).
CAUTION!
Do not run a fabric top through an automatic car
wash. Window scratches and wax buildup may result.
 Do not lower the top when the temperature is below
41°F (5°C). Damage to the top may result.
 Do not move your vehicle until the top has been
either fully attached to the windshield frame, or fully
lowered.
 Do not fully lower the top with the windows installed.
Window and top damage may occur.
 For important information on cleaning and caring for
your vehicle's fabric top
Úpage 361.
 Do not use any tools (screwdrivers, etc.) to pry or
force any of the clamps, clips, or retainers securing
the soft top. Do not force or pry the soft top frame -
work when opening or closing. Damage to the top
may result.
Failure to follow these cautions may cause interior water
damage, stains or mildew on the top material:
 It is recommended that the top be free of water prior
to opening it. Operating the top, opening a door or
lowering a window while the top is wet may allow
water to drip into the vehicle's interior.
 Careless handling and storage of the soft top may
damage the seals, causing water to leak into the
vehicle's interior.
 The soft top must be positioned properly to ensure
sealing. Improper installation can cause water to leak
into the vehicle's interior.
CAUTION!

CAUTION!
 The hard top is not designed to carry any additional
loads, such as after-market roof racks, spare tires,
building materials, hunting or camping supplies, etc.
For optional Mopar® accessory roof racks
Úpage 102.
 Do not move your vehicle until the top has been
either fully attached to the front header, sport bar,
and body side or fully removed.
Failure to follow these cautions may cause interior
water damage, stains or mildew:
It is recommended that the top be free of water prior
to panel removal. Removing the top, opening a door
or lowering a window while the top is wet may allow
water to drip into the vehicle’s interior.
 The hard top assembly must be positioned properly
to ensure sealing. Improper installation can cause
water to leak into the vehicle’s interior.
 Careless handling and storage of the removable roof
panels may damage the seals, causing water to leak
into the vehicle’s interior.
 The front panel(s) must be positioned properly to
ensure sealing. Improper installation can cause
water to leak into the vehicle’s interior.

Service Forward Collision Warning (FCW)
Light — If Equipped
This warning light will illuminate to indicate a
fault in the Forward Collision Warning System.
Contact an authorized dealer for service
Úpage 255.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning properly
and service is required. Contact an authorized
dealer for service.
Cruise Control Fault Warning Light
This warning light will illuminate to indicate the
Cruise Control system is not functioning
properly and service is required. Contact an
authorized dealer.
Sway Bar Fault Warning Light
This light will illuminate when there is a fault in
the sway bar disconnect system Úpage 145.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is
displayed to indicate that the tire pressure is
lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel consumption may not
be guaranteed. Should one or more tires be in the condition previously
mentioned, the display will show the indications
corresponding to each tire.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire pressure
telltale when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pressure
telltale illuminates, you should stop and check your tires
as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under inflated tire
causes the tire to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver’s responsibility to
maintain correct tire pressure, even if underinflation has not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent
vehicle start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the system may
not be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or
wheels on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to
function properly.
CAUTION!

Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle, avoid
-
ing sharp braking and steering. If a tire puncture occurs,
repair immediately using the dedicated tire repair kit and
contact an authorized dealer as soon as possible.

CAUTION!
The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equipment
that is not of the same size, type, and/or style. After -
market wheels can cause sensor damage. Using after -
market tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inopera -
ble. After using an aftermarket tire sealant it is recom -
mended that you take your vehicle to an authorized
dealer to have your sensor function checked.

STARTING AND OPERATING141
FOUR-POSITION TRANSFER CASE —
I
F 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 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 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).
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. 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 141.
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 OR 4H TO 2H
Shifting between 2H and 4H 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.

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.

170STARTING AND OPERATING
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for
increased durability do not necessarily increase the
vehicle's GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size
listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
Curb Weight
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
Loading
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to ensure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should then
be determined separately to be sure that the load is
properly distributed over the front and rear axle. Weighing
the vehicle may show that the GAWR of either the front or
rear axles has been exceeded but the total load is within
the specified GVWR. If so, weight must be shifted from
front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier
items down low and be sure that the weight is distributed
equally. Stow all loose items securely before driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR
Úpage 169.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its "loaded and
ready for operation" condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
WARNING!
Do not load your vehicle any heavier than the GVWR or
the maximum front and rear GAWR. If you do, parts on
your vehicle can break, or it can change the way your
vehicle handles. This could cause you to lose control.
Overloading can shorten the life of your vehicle.

23_JL_OM_EN_USC_t.book Page 170

STARTING AND OPERATING173
(Continued)
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!
