INTRODUCTION
Congratulations on selecting your new FCA US LLC ve-
hicle. Be assured that it represents precision workmanship,
distinctive styling, and high quality.
This is a specialized utility vehicle. It can go places and
perform tasks that are not intended for conventional pas-
senger cars. It handles and maneuvers differently from
many passenger cars, both on-road and off-road, so take
time to become familiar with your vehicle.
The two-wheel drive version of this vehicle was designed
for on-road use only. It is not intended for off-road driving
or use in other severe conditions suited for a four-wheel
drive vehicle.
Before you start to drive this vehicle, read the Owner’s
Manual. Be sure you are familiar with all vehicle controls,
particularly those used for braking, steering, transmission,
and transfer case shifting. Learn how your vehicle handles
on different road surfaces. Your driving skills will improve
with experience. When driving off-road, or working the
vehicle, don’t overload the vehicle, or expect the vehicle to
overcome the natural laws of physics.
Always observe federal, state, provincial, and local laws
wherever you drive.As with other vehicles of this type, failure to operate this
vehicle correctly may result in loss of control or a collision.
Refer to “Driving Tips” in “Starting And Operating” for
further information.
This Owner’s Manual has been prepared with the assis-
tance of service and engineering specialists to acquaint you
with the operation and maintenance of your vehicle. It is
supplemented by Warranty Information, and various
customer-oriented documents. Please take the time to read
these publications carefully. Following the instructions and
recommendations in this manual will help assure safe and
enjoyable operation of your vehicle.

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.).
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
coating on 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.
CAUTION!
• Do not run a fabric top through an automatic car
wash. Window scratches and wax build up 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 lower the top with the windows installed.
Window and top damage may occur.
• Refer to “Appearance Care For Fabric Top Models”
in “Bodywork” in “Servicing And Maintenance” for
further information. It contains important informa-
tion on cleaning and caring for your vehicle’s fabric
top.
• 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.

Oil Change Required
Your vehicle is equipped with an engine oil change indi-
cator system. The “Oil Change Required” message will
display in the instrument cluster display for approximately
10 seconds after a single chime has sounded to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON position. To
turn off the message temporarily, push and release the
MENUbutton. To reset the oil change indicator system
(after performing the scheduled maintenance), perform the
following procedure:
1. Turn the ignition switch to the ON position. Do not start
the engine.
2. Fully push the accelerator pedal slowly three times within 10 seconds.
3. Turn the ignition switch to the LOCK position.
NOTE: If the indicator message illuminates when you
start the vehicle, the oil change indicator system did not
reset. If necessary, repeat this procedure.
WARNING/INDICATOR LIGHTS AND MESSAGES
The warning/indicator light switches on in the instrument
panel together with a dedicated message and/or acoustic
signal when applicable. These indications are indicative
and precautionary and as such must not be considered as
exhaustive and/or alternative to the information contained
in the Owner Manual, which you are advised to read
carefully in all cases. Always refer to the information in this
chapter in the event of a failure indication.
All active telltales will display first, if applicable. The
system check menu may appear different based upon
equipment options and current vehicle status. Some tell-
tales are optional and may not appear.

As an added safety feature, your vehicle has been equipped
with a Tire Pressure Monitoring System (TPMS) that illumi-
nates a low tire pressure telltale when one or more of your
tires is significantly under-inflated. 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.
Under-inflation 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 main-
tain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunc-
tion 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 todetect 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!
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 equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Using
aftermarket tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inoper-
able. After using an aftermarket tire sealant it is
recommended that you take your vehicle to an autho-
rized dealer to have your sensor function checked.

Onboard Diagnostic System (OBD II) Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emissions
controls. Authorized service technicians may need to ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
WARNING!
•ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the OBD
II connection port, such as a driver-behavior tracking
device, it may:
• Be possible that vehicle systems, including safety
related systems, could be impaired or a loss of
vehicle control could occur that may result in an
accident involving serious injury or death.
• Access, or allow others to access, information
stored in your vehicle systems, including personal
information. For further information, refer to “Privacy Practices” and
“Uconnect CyberSecurity” in “All About Uconnect Access”
in your Owner ’s Manual Radio Supplement and “Cyber-
security” in “Multimedia”.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is possibly loose, improperly
installed, or damaged. A “gASCAP” message will be
displayed in the odometer. Tighten the gas cap until a
clicking
sound is heard. This is an indication that the gas
cap is properly tightened. Push the odometer reset button
to turn the message off. If the problem persists, the
message will appear the next time the vehicle is started.
This might indicate a damaged cap. If the problem is
detected twice in a row, the system will turn on the MIL.
Resolving the problem will turn the MIL off.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass an
inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.

the intended path, ESC applies the brake of the appropriate
wheel to assist in counteracting the oversteer or understeer
condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster), starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during accel-
eration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
WARNING!
•Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. ESC cannot prevent accidents, including
(Continued)
WARNING! (Continued)
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC equipped
vehicle must never be exploited in a reckless or dan-
gerous manner which could jeopardize the user ’s safety
or the safety of others.
•Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteristics
of your vehicle, and may negatively affect the perfor-
mance of the ESC system. Changes to the steering
system, suspension, braking system, tire type and size
or wheel size may adversely affect ESC performance.
Improperly inflated and unevenly worn tires may also
degrade ESC performance. Any vehicle modification or
poor vehicle maintenance that reduces the effective-
ness of the ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal injury and
death.

SAFETY 219

AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitor System (TPMS)
The Tire Pressure Monitoring System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
The tire pressure will vary with temperature by about 1 psi
(7.0 kPa) for every 12°F (6.5°C). This means that when the
outside temperature decreases, the tire pressure will de-
crease. Tire pressure should always be set based on cold
inflation tire pressure. This is defined as the tire pressure
after a vehicle has not been driven for more than three
hours, or driven less than 1 mile (1.6 km) after a three-hour
period. Refer to “Tires” in “Servicing and Maintenance” for
information on how to properly inflate the vehicle’s tires.
The tire pressure will also increase as the vehicle is driven;
this is normal and there should be no adjustment for this
increased pressure.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects, or
natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turnoff until the tire pressure is at or above recommended cold
placard pressure. Once the “Tire Pressure Monitoring Tell-
tale Light” has been illuminated, the tire pressure must be
increased to the recommended cold placard pressure in
order for the “Tire Pressure Monitoring Telltale Light” to be
turned OFF.
NOTE:
When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
The system will automatically update and the “Tire Pres-
sure Monitoring Telltale Light” will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) air pressure of 35 psi
(241 kPa). If the ambient temperature is 68°F (20°C) and the
measured tire pressure is 30 psi (207 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pressure to
approximately 26 psi (179 kPa). This tire pressure is suffi-
ciently low enough to turn ON the “Tire Pressure Moni-
toring Telltale Light.” Driving the vehicle may cause the
tire pressure to rise to approximately 30 psi (207 kPa), but
