Fuel And AdBlue® (UREA) Filler Location
Refilling With Nozzles
You can fill up at any AdBlue® (UREA)
distributor.
Proceed as follows:
Insert the AdBlue® (UREA) nozzle in the
filler, start refilling and stop refilling at the
first shut-off (the shut-off indicates that
the AdBlue® (UREA) tank is full). Do not
proceed with the refilling, to prevent
spillage of AdBlue® (UREA).
Extract the nozzle. Refilling With Containers
Proceed as follows:
Check the expiration date.
Read the advice for use on the label before
pouring the content of the bottle into the
AdBlue® (UREA) tank.
If systems which cannot be screwed in
(e.g. tanks) are used for refilling, after the
indication appears on the instrument
panel display refer to “Warning lights And
Messages” in the “Getting To Know Your
Instrument Panel” for further information,
fill the AdBlue® (UREA) tank with no
more than 1.6 Gallons (6 liters).
If containers which can be screwed to the
filler are used, the reservoir is full when
the AdBlue® (UREA) level in the
container stops pouring out. Do not
proceed further.
Operations After Refilling
Proceed as follows:
Fit the cap back on the AdBlue® (UREA)
filler by turning it clockwise and screwing
it completely.
Place the ignition to RUN (it is not neces-
sary to start the engine).
Wait for the indication on the instrument
panel to switch off before moving the car.
The indication may stay on for a few
seconds to approximately half a minute. If
the engine is started and the car is moved,
the indication will remain on for longer.
This will not compromise engine opera-
tion.
If the AdBlue® (UREA) was topped up
when the tank was empty, wait for
2 minutes before starting the engine.

FUSES
General Information
The fuses protect electrical systems against
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
discharge.
Blade Fuses
WARNING!
When replacing a blown fuse, always use
an 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 mate-
rial. Do not place a fuse inside a circuit
breaker cavity or vice versa. Failure to
use proper fuses may result in serious
personal injury, fire and/or property
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.
If a general protection fuse for safety
systems (air bag system, braking
system), power unit systems (engine
system, transmission system) or steering
system blows, contact an authorized
dealer.
CAUTION!
If it is necessary to wash the engine
compartment, take care not to directly hit
the fuse box, and the windshield wiper
motors with water.

3. Place the transmission in PARK (P) (autotransmission) or in Gear (manual trans -
mission) and place the ignition in the
OFF position.
4. Apply the parking brake.
(B) Setting Up To Use Tire Service Kit:
1. Push in the Mode Select Knob and turn to the Sealant Mode position.
2. Uncoil the Sealant Hose and then remove the cap from the fitting at the end of the
hose.
3. Place the Tire Service Kit flat on the ground next to the deflated tire.
4. Remove the cap from the valve stem and then screw the fitting at the end of the
Sealant Hose onto the valve stem.
5. Uncoil the Power Plug and insert the plug into the vehicle’s 12 Volt power outlet.
NOTE:
Do not remove foreign objects (e.g., screws
or nails) from the tire.
(C) Injecting Tire Service Kit Sealant Into
The Deflated Tire:
Always start the engine before turning ON
the Tire Service Kit.
NOTE:
Manual transmission vehicles must have the
parking brake engaged and the gear selector
in NEUTRAL.
After pushing the Power Button, the
sealant (white fluid) will flow from the
Sealant Bottle through the Sealant Hose
and into the tire.
NOTE:
Sealant may leak out through the puncture in
the tire. If the sealant (white fluid) does not flow within
0 – 10 seconds through the Sealant Hose:
1. Push the Power Button to turn Off the
Tire Service Kit. Disconnect the Sealant
Hose from the valve stem. Make sure the
valve stem is free of debris. Reconnect
the Sealant Hose to the valve stem.

NOTE:
If the Mode Select Knob is on Air Mode and
the pump is operating, air will dispense from
the Air Pump Hose only, not the Sealant
Hose.
If the sealant (white fluid) does flow through the
Sealant Hose: 1. Continue to operate the pump until
sealant is no longer flowing through the
hose (typically takes 30 - 70 seconds). As the sealant flows through the Sealant
Hose, the Pressure Gauge can read as

SERVICING AND MAINTENAN
CESCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the car under the best condi-
tions. For this reason, Jeep has planned a
series of checks and services at fixed
distance intervals and, where provided, at
fixed time intervals, as described in the
Scheduled Servicing plan. To keep the car’s
efficiency in tip-top condition, in the
following Scheduled Service plan pages a
few additional checks are listed that should
be carried out more frequently with respect
to the normal coupon redemption schedule.
Scheduled Servicing is offered by all autho -
rized dealerships according to fixed time or
mileage intervals. If, during each operation,
in addition to the ones scheduled, the need
arises for further replacements or repairs,
these may be carried out with the owner's
explicit agreement only.
The technicians at your dealership know your
vehicle best, and have access to factory
trained information, genuine Mopar parts,
and specially designed electronic and
mechanical tools that can help prevent
future costly repairs. If your car is used
frequently for towing, the interval between
one scheduled servicing operation and the next should be reduced. More frequent main
-
tenance may be needed for vehicles in severe
operating conditions, such as dusty areas
and very short trip driving.
NOTE:
Scheduled Servicing interventions are set
out by the Manufacturer. Failure to have
them carried out may invalidate the
warranty. It is advised to inform an autho -
rized dealership of any small operating irreg -
ularities without waiting for the next service.
Scheduled Servicing — Gasoline Engine
The oil change indicator system will remind
you that it is time to take your vehicle in for
engine oil replacement.
An “Oil Change Required” message will be
displayed in the instrument cluster and a
single chime will sound, indicating that an
oil change is necessary.
The oil change indicator message will illumi -
nate approximately 7,000 miles
(11,200 km) after the most recent oil
change was performed. Have your vehicle
serviced as soon as possible, within
500 miles (800 km). NOTE:
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle’s oil if it has been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
Change your engine oil more often if you
drive your vehicle off-road for an extended
period of time (refer to the “Heavy Duty
Use of Vehicle” section).
Under no circumstances should oil change
intervals exceed 7,500 miles
(12,000 km) or 12 months, whichever
comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.

-
tion in the table, continue with the sched -

maintenance items may result in damage
to the vehicle.
