Enhanced Accident Response System
In the event of an impact, if the communica-
tion network remains intact, and the power
remains intact, depending on the nature of
the event, the ORC will determine whether to
have the Enhanced Accident Response Sys-
tem perform the following functions:
• Cut off fuel to the engine (If Equipped)
• Cut off battery power to the electric motor
(If Equipped)
• Flash hazard lights as long as the battery
has power
• Turn on the interior lights, which remain on
as long as the battery has power or for 15
minutes from the intervention of the En-
hanced Accident Response System.
• Unlock the power door locks.
Your vehicle may also be designed to perform
any of these other functions in response to
the Enhanced Accident Response System:
• Turn off the Fuel Filter Heater, Turn off the
HVAC Blower Motor, Close the HVAC Circu-
lation Door• Cut off battery power to the:
– Engine
– Electric Motor (if equipped)
– Electric power steering
– Brake booster

After an accident, remember to cycle the
ignition to the STOP (OFF/LOCK) position
and remove the key from the ignition switch
to avoid draining the battery. Carefully check
the vehicle for fuel leaks in the engine com-
partment and on the ground near the engine
compartment and fuel tank before resetting
the system and starting the engine. If there
are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any
doubt, contact an authorized dealer.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Re-
sponse System functions after an event, the
ignition switch must be changed from igni-
tion START or ON/RUN to ignition OFF. Care-
fully check the vehicle for fuel leaks in the
engine compartment and on the ground near
the engine compartment and fuel tank before
resetting the system and starting the engine.

CAUTION!
For diesel engines, only use diesel fuel for
motor vehicles in accordance with EN 590
European specifications. The use of other
products or mixtures may damage the en-
gine beyond repair and consequently void
the warranty, due to the damage caused. If
you accidentally introduce other types of
fuel into the tank, do not start the engine.
Empty the tank. If the engine has been run
for even an extremely limited amount of
time, you must not only drain the fuel
tank, but the rest of the supply circuit as
well.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can
cause severe damage to the engine fuel sys-
tem. Proper maintenance of the engine fuel
filter and fuel tank is essential. Refer to
“Dealer Service” in “Servicing And Mainte-
nance” in your Owner’s Manual for further
information.
AdBlue® (UREA) — If Equipped
The vehicle is equipped with an UREA injec-
tion system and Selective Catalytic Reduc-
tion to meet emission standards. These two
systems ensure compliance with the diesel
emissions requirements; at the same, they
ensure fuel-efficiency, handling, torque and
power. For messages and system warnings,
refer to the "Warning Lights And Messages" in
the "Getting To Know Your Instrument Panel"
section. AdBlue
®is a very stable product
with a long shelf life. Stored at temperatures
LOWER than 90 °F (32 °C), it has a shelf life
of at least one year. For more information on
the AdBlue
®liquid type, see the “Fluids and
lubricants” in the “Technical specifications”
section. The vehicle is equipped with an
automatic AdBlue
®heating system when the
engine starts allowing the system to work
correctly at temperatures lower than 12 °F
(-11 °C).
NOTE:
• AdBlue
®freezes at temperatures lower
than 12 °F (-11 °C).• Your vehicle is equipped with a AdBlue
®
injection system. You may occasionally
hear an audible clicking noise from under
the vehicle at a stop. This is normal opera-
tion.
• The AdBlue
®pump will run for a period of
time after engine shutdown to purge the
AdBlue
®system. This is normal operation
and may be audible from the rear of the
vehicle.
AdBlue® Storage
AdBlue®is considered a very stable product
with a long shelf life. If AdBlue®is kept in
temperatures between 10° and 90°F
(-12° and 32°C), it will last a minimum of
one year.
AdBlue
®is subject to freezing at the lowest
temperatures. For example, AdBlue®may
freeze at temperatures at or below 12° F
(-11° C). The system has been designed to
operate in this environment.

Bulb Replacement
High Intensity Discharge Headlamps (HID)
—
If Equipped
The headlamps are a type of high voltage
discharge tube. High voltage can remain in
the circuit even with the headlamp switch off
and the key removed.Because of this, you
should not attempt to service a headlamp bulb
yourself. If a headlamp bulb fails, take your
vehicle to an authorized dealer for service.
WARNING!
A transient high voltage occurs at the bulb
sockets of High Intensity Discharge (HID)
headlamps when the headlamp switch is
turned ON. It may cause serious electrical
shock or electrocution if not serviced prop-
erly. See your authorized dealer for
service.NOTE:
On vehicles equipped with High Intensity
Discharge (HID) headlamps, when the head-
lamps are turned on, there is a blue hue to
the lamps. This diminishes and becomes
more white after approximately 10 seconds,
as the system charges.
Halogen Headlamps — If Equipped
NOTE:
We advise referring to an authorized dealer.
NOTE:
Lens fogging can occur under certain atmo-
spheric conditions. This will usually clear as
atmospheric conditions change to allow the
condensation to change back to vapor. Turn-
ing the lamps on will usually accelerate the
clearing process.
1. Open the hood.
2. Access the back of the headlamp.NOTE:
• The air filter housing must be removed.
• The windshield washer reservoir may
need to be rotated out of the way by
removing the fastener.
• Coolant reservoir (if equipped) will
need to be repositioned by removing
the fasteners, and moving the unit out
of the way.
3. To access the low beam bulb you must
remove the rubber boot seal from back-
side of the lamp housing.
NOTE:
Ensure the rubber boot is properly rein-
stalled to prevent water and moisture from
entering the lamp.
CAUTION!
•Do not contaminate the bulb glass by
touching it with your fingers or by allow-
ing it to contact other oily surfaces.
Shortened bulb life will result.
IN CASE OF EMERGENCY
206

CAUTION!
• Always use the correct bulb size and type
for replacement. An incorrect bulb size
or type may overheat and cause damage
to the lamp, the bulb socket, or the lamp
wiring.
4. Turn the low or high beam bulb one–
quarter turn counterclockwise to remove
from housing.
5. Disconnect the electrical connector and
replace the bulb.
Front Turn Signal Lamp
SRT vehicles are equipped with front turn
signal lamps are LEDs. See your authorized
dealer for service.
NOTE:
We advise referring to an authorized dealer.
1. Open the hood.
2. Access the back of the headlamp.NOTE:
• The air filter housing must be removed.
• The windshield washer reservoir may
need to be rotated out of the way by
removing the fastener.
• Coolant reservoir (if equipped) will
need to be repositioned by removing the
fasteners, and moving the unit out of
the way.
3. Turn the turn signal bulb one–quarter turn
counterclockwise to remove from housing.
4. Disconnect the electrical connector and
replace the bulb.
CAUTION!
Do not touch the new bulb with your fin-
gers. Oil contamination will severely
shorten bulb life. If the bulb comes in
contact with any oily surface, clean the
bulb with rubbing alcohol.
Front Fog Lamps
Please see your authorized dealer for service.
Rear Tail, Stop, and Turn Signal Lamps
1. Raise the liftgate.
2. Remove the two push-pins from the tail

work for which you have the knowledge
and the right equipment. If you have any
239

WARNING!
doubt about your ability to perform a
service job, take your vehicle to a com-
petent mechanic.
• Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.
Severe Duty Conditions
**** Change the engine oil and engine oil
filter at every 4500 miles (7,500 km) or
12 months if using your vehicle under any of
the following severe duty conditions:
• Stop and go driving.
• Driving in dusty conditions.
• Short trips of less than 10 miles (16 km).
• Trailer towing.
• Taxi, police, or delivery service (commercial
service).
• Off-road or desert operation.
Scheduled Servicing — SRT
Correct servicing is crucial for guaranteeing a
long life for the car under the best conditions.
For this reason, Jeep has planned a series of
checks and services at fixed distance inter-
vals and, where provided, at fixed time inter-
vals, 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 redemp-
tion schedule. Scheduled Servicing is offered
by all authorized dealerships according to
fixed time or mileage intervals. If, during
each operation, in addition to the ones
scheduled, the need arises for further re-
placements 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 me-
chanical tools that can help prevent future
costly repairs. If your car is used frequently
for towing, the interval between one sched-uled servicing operation and the next should
be reduced. More frequent maintenance 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 authorized dealership of
any small operating irregularities without
waiting for the next service.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
The Instrument Cluster Display will display
an “Oil Change Required” message and a
single chime will sound, indicating that an oil
change is necessary.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Have your vehicle serviced as soon as
possible, within the next 500 miles
(805 km).
