INSTALLATION OF RADIO TRANSMITTING
EQUIPMENT
Special design considerations are incorporated into this
vehicle’s electronic system to provide immunity to radio
frequency signals. Mobile two-way radios and telephone
equipment must be installed properly by trained person-
nel. The following must be observed during installation.
The positive power connection should be made directly
to the battery and fused as close to the battery as possible.
The negative power connection should be made to body
sheet metal adjacent to the negative battery connection.
This connection should not be fused.
Antennas for two-way radios should be mounted on the
roof or the rear area of the vehicle. Care should be used
in mounting antennas with magnet bases. Magnets may
affect the accuracy or operation of the compass on
vehicles so equipped.
The antenna cable should be as short as practical and
routed away from the vehicle wiring when possible. Use
only fully shielded coaxial cable.
Carefully match the antenna and cable to the radio to
ensure a low Standing Wave Ratio (SWR).Mobile radio equipment with output power greater than
normal may require special precautions.
All installations should be checked for possible interfer-
ence between the communications equipment and the
vehicle’s electronic systems.
WARNING:
Operating, servicing and maintaining a
passenger vehicle or off-road highway
motor vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to
the State of California to cause cancer and
birth defects or other reproductive harm.
To minimize exposure, avoid breathing
exhaust, do not idle the engine except as
necessary, service your vehicle in a
well-ventilated area and wear gloves or
wash your hands frequently when servicing
your vehicle. For more information go to

DRIVING AND ALCOHOL
Drunken driving is one of the most frequent causes of
accidents.
Your driving ability can be seriously impaired with blood
alcohol levels far below the legal minimum. If you are
drinking, don’t drive. Ride with a designated non-
drinking driver, call a cab, a friend, or use public trans-
portation.
WARNING!
Driving after drinking can lead to an accident.
Your perceptions are less sharp, your reflexes are
slower, and your judgment is impaired when you
have been drinking. Never drink and then drive.
This manual illustrates and describes the operation of
features and equipment that are either standard or op-
tional on this vehicle. This manual may also include a
description of features and equipment that are no longer
available or were not ordered on this vehicle. Please
disregard any features and equipment described in this
manual that are not on this vehicle.
FCA US LLC reserves the right to make changes in design

RUN
•Driving position.
• All the electrical devices are available.
START
• The engine will start.
Page 57 of 630
NOTE:
•Once a heat setting is selected, heat will be felt within
two to five minutes.
• The engine must be running for the heated seats to
operate.
Vehicles Equipped With Remote Start
On models that are equipped with remote start, the heated
seats can be programmed to come on during a remote start.
This feature can be programmed through the Uconnect
system. Refer to “Uconnect Settings” in “Multimedia” for
further information.

2. Reach under the hood, move safety latch to the left andlift the hood.To Close The Hood
1. Hold up the hood with one hand and with the otherhand remove the support rod from its seat and reinsert
it into the locking tab.
2. Lower the hood to approximately 12 inches (30 cm) from the engine compartment and drop it. Make sure that the
hood is completely closed.

Instrument Cluster Descriptions
1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Speedometer •Indicates vehicle speed.
3. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather or up mountain
grades. It should not be allowed to exceed the upper
limits of the normal operating range.

— Battery Charge Warning Light
This light illuminates when the battery is not charging
properly. If it stays on while the engine is running, there
may be a malfunction with the charging system. Contact an
authorized dealer as soon as possible.
This indicates a possible problem with the electrical system
or a related component.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
an authorized dealer for service as soon as possible.

WARNING!(Continued)
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 “Cybersecurity” in “Mul-
timedia”.
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. For states that require an Inspection and Main-
tenance (I/M), this check verifies the “Malfunc-
tion Indicator Light (MIL)” is functioning and is
not on when the engine is running, and that the
OBD II system is ready for testing.
Normally, the OBD II system will be ready. The OBD II
system may notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace- ment. If the OBD II system should be determined not ready
for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle’s OBD II system is ready, you must do the follow-
ing:
1. Cycle the ignition switch to the ON position, but do not
crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the “Malfunction Indicator Light
(MIL)” symbol come on as part of a normal bulb check.
3. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about ten seconds and then return
to being fully illuminated until you turn OFF the igni-
tion or start the engine. This means that your vehicle’s
OBD II system is not readyand you should notproceed
to the I/M station.
