FUSES
WARNING!
• When replacing a blown fuse, always usean appropriate replacement fuse with
the same amp rating as the original fuse.
Never replace a fuse with another fuse of
higher amp rating. Never replace a
blown fuse with metal wires or any other
material. Do not place a fuse inside a
circuit breaker cavity or vice versa. Fail-
ure to use proper fuses may result in
serious personal injury, fire and/or prop-
erty damage.
• Before replacing a fuse, make sure that
the ignition is off and that all the other
services are switched off and/or disen-
gaged.
• If the replaced fuse blows again, contact
an authorized dealer.
WARNING!

excessive current.
When a device does not work, you must check
the fuse element inside the blade fuse for a
break/melt.
Also, please be aware that when using power
outlets for extended periods of time with the
engine off may result in vehicle battery dis-
charge.
Underhood Fuses
The Power Distribution Center is located in
the engine compartment near the battery.
This center contains cartridge fuses, mini-
fuses and relays. A label that identifies each
component is printed on the inside of the

JUMP STARTING
If your vehicle has a discharged battery, it can
be jump started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump starting
can be dangerous if done improperly, so please
follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack,
follow the manufacturer’s operating instruc-
tions and precautions.
WARNING!
Do not attempt jump starting if the battery
is frozen. It could rupture or explode and
cause personal injury.
CAUTION!
Do not use a portable battery booster pack
or any other booster source with a system
voltage greater than 12 Volts or damage to
the battery, starter motor, alternator or
electrical system may occur.
Preparations For Jump Start
The battery in your vehicle is located in the
front of the engine compartment, behind the
left headlight assembly.
WARNING!
• Take care to avoid the radiator coolingfan whenever the hood is raised. It can
start anytime the ignition switch is ON.
WARNING!
You can be injured by moving fan
blades.
• Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
• Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
1. Apply the parking brake, shift the auto- matic transmission into PARK (manual
transmission in NEUTRAL) and turn the
ignition to LOCK.

Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
devices to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
NOTE:
• You must ensure that the Auto Park Brakefeature is disabled before towing this ve-
hicle, to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake
feature is enabled or disabled via the cus-
tomer programmable features in the
Uconnect Settings.
• Vehicles with a discharged battery or total electrical failure when the electric park
brake (EPB) is engaged, will need a wheel
dolly or jack to raise the rear wheels off the
ground when moving the vehicle onto a
flatbed. If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.
Note that the Safehold feature will engage
the Electric Park Brake whenever the driver's
door is opened (if the battery is connected,
ignition is ON, transmission is not in PARK,
and brake pedal is released). If you are towing
this vehicle with the ignition in the ON/RUN
mode, you must manually disable the Elec-
tric Park Brake each time the driver's door is
opened, by pressing the brake pedal and then
releasing the EPB.
If the vehicle’s battery is discharged, refer to
“Gear Selector Override” in this section for
instructions on shifting the automatic trans-
mission out of PARK so that the vehicle can
be moved.
CAUTION!
• Do not use sling-type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flatbed
truck, do not attach to front or rear
CAUTION!
suspension components. Damage to
your vehicle may result from improper
towing.
• Ensure that the Electric Park Brake is
released, and remains released, while
being towed.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Front-Wheel Drive (FWD) Models — With
Key Fob
The manufacturer recommends towing your
vehicle with all four wheels OFFthe ground
using a flatbed.

Checking Oil Level
To assure proper engine lubrication, the en-
gine oil must be maintained at the correct
level. Check the oil level at regular intervals,
such as every fuel stop. The best time to
check the engine oil level is about five min-
utes after a fully warmed up engine is shut
off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings.
There are three possible dipstick types,
• Crosshatched zone.
• Crosshatched zone marked SAFE.
• Crosshatched zone marked with MIN at thelow end of the range and MAX at the high
end of the range.
NOTE:
Always maintain the oil level within the cross-
hatch markings on the dipstick.
Adding 1 quart (1.0 liters) of oil when the
reading is at the low end of the dipstick range
will raise the oil level to the high end of the
range marking.
CAUTION!
Overfilling or underfilling the crankcase
will cause aeration or loss of oil pressure.
This could damage your engine.
Cooling System
WARNING!
• You or others can be badly burned by hot engine coolant (antifreeze) or steam
from your radiator. If you see or hear
steam coming from under the hood, do
not open the hood until the radiator has
had time to cool. Never open a cooling
system pressure cap when the radiator
or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling
fan, disconnect the fan motor lead or
turn the ignition to the OFF mode. The
WARNING!
fan is temperature controlled and can
start at any time the ignition is in the ON
mode.
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty, the sys-
tem should be drained, flushed, and refilled
with fresh PARAFLU
UPFormula OAT (Or-
ganic Additive Technology) or equivalent
meeting the requirements of FCA Material
Standard MS.90032. by an authorized
dealer. Check the front of the A/C condenser
for any accumulation of bugs, leaves, etc. If
dirty, clean by gently spraying water from a
garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the coolant
recovery bottle and radiator. Inspect the en-

• Do not drain the engine cooling system.
• Whenever you leave the vehicle is station-ary for two weeks or more, run idle the
engine for approximately five minutes, with
the air conditioning system on and high fan
speed. This will ensure a proper lubrication
of the system, thus minimizing the possi-
bility of damage to the compressor when
the vehicle is put back into operation.
NOTE:
When the vehicle has not been started or driven
for at least 30 days, an Extended Park Start
Procedure is required to start the vehicle. Refer
to “Starting The Engine” in “Starting And
Operating” for further information.
CAUTION!
Before removal of the positive and nega-
tive terminals to the battery, wait at least a
minute with ignition switch in the OFF
position and close the driver’s door. When
reconnecting the positive and negative ter-
minals to the battery be sure the ignition
switch is in the OFF position and the
driver’s door is closed.
BODYWORK
Preserving The Bodywork
Washing
• Wash your vehicle regularly. Always wash your vehicle in the shade using a mild car
wash soap, and rinse the panels completely
with clear water.
• Use a high quality cleaner wax to remove road film, stains and to protect your paint
finish. Take care never to scratch the paint.
• Avoid using abrasive compounds and power buffing that may diminish the gloss or thin
out the paint finish.
CAUTION!
• Do not use abrasive or strong cleaning materials such as steel wool or scouring
powder that will scratch metal and
painted surfaces.
• Use of power washers exceeding
1,200 psi (8,274 kPa) can result in
damage or removal of paint and decals.
Special Care
• If you drive on salted or dusty roads or if youdrive near the ocean, hose off the undercar-
riage at least once a month.
• It is important that the drain holes in the lower edges of the doors, rocker panels, and
trunk be kept clear and open.
• If you detect any stone chips or scratches in the paint, touch them up immediately. The
cost of such repairs is considered the re-
sponsibility of the owner.
• If your vehicle is damaged due to a collision or similar cause that destroys the paint and
protective coating, have your vehicle re-
paired as soon as possible. The cost of such
repairs is considered the responsibility of
the owner.
