exhaust system could occur soon with con-
tinued operation.
•Exhaust Filter Full — Power Reduced See
Dealer— This message indicates the PCM
has derated the engine to limit the likeli-
hood of permanent damage to the after-
treatment system. If this condition is not
corrected and a dealer service is not per-
formed, extensive exhaust after-treatment
damage can occur. To correct this condition
it will be necessary to have your vehicle
serviced by an authorized dealer.
NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles remaining will prevent
the diesel exhaust filter from performing it's
cleaning routine. This will shortly result in a
Malfunction Indicator Light (MIL) and re-
duced engine power. Only an authorized
dealer will be able to correct this condition.
CAUTION!
See an authorized dealer, as damage to the
exhaust system could occur soon with con-
tinued operation.

FCW Braking Status And Sensitivity
The FCW Sensitivity and Active Braking sta-
tus are programmable through the Uconnect
System. Refer to “Uconnect Settings” in
“Multimedia” in the Owner’s Manual for fur-
ther information.
The default sensitivity of FCW is the “Me-
dium” setting and the system status is
“Warning & Braking”. This allows the system
to warn the driver of a possible collision with
the vehicle in front using audible/visual warn-
ings and it applies autonomous braking.
Changing the FCW status to “Far” setting
allows the system to warn the driver of a
possible collision with the vehicle in front
using audible/visual warning when the latter
is at a farther distance than "Medium" set-
ting. This provides the most reaction time to
avoid a possible collision.
Changing the FCW status to the “Near” set-
ting, allows the system to warn the driver of a
possible collision with the vehicle in front
when the distance between the vehicle in the
front is much closer. This setting providesless reaction time than the “Far” and “Me-
dium” settings, which allows for a more dy-
namic driving experience.
NOTE:
• Changing the FCW status to “Only Warn-
ing” prevents the system from providing
limited active braking, or additional brake
support if the driver is not braking ad-
equately in the event of a potential frontal
collision, but maintains the audible and
visual warnings.
• Changing the FCW status to “Off” prevents
the system from providing autonomous
braking, or additional brake support if the
driver is not braking adequately in the event
of a potential frontal collision.
• The system will NOT retain the last setting
selected by the driver after ignition shut
down. The system will reset to "Medium"
sensitivity and system status as “Warning &
Braking” when the vehicle is restarted.• FCW may not react to irrelevant objects
such as overhead objects, ground reflec-
tions, objects not in the path of the vehicle,
stationary objects that are far away, oncom-
ing traffic, or leading vehicles with the
same or higher rate of speed.
• FCW will be disabled like ACC, with the
unavailable screens.
FCW Limited Warning
If the instrument cluster displays “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield” mo-
mentarily, there may be a condition that lim-
its FCW functionality. Although the vehicle is
still drivable under normal conditions, the
active braking may not be fully available.
Once the condition that limited the system
performance is no longer present, the system
will return to its full performance state. If the
problem persists, see your authorized dealer.

Active Head Restraint (AHR) Components:WARNING!
• All occupants, including the driver,
should not operate a vehicle or sit in a
vehicle’s seat until the head restraints
are placed in their proper positions in
order to minimize the risk of neck injury
in the event of a collision.
• Do not place items over the top of the
Active Head Restraint, such as coats,
seat covers or portable DVD players.
These items may interfere with the op-
eration of the Active Head Restraint in
the event of a collision and could result
in serious injury or death.
• Active Head Restraints may be deployed
if they are struck by an object such as a
hand, foot or loose cargo. To avoid acci-
dental deployment of the Active Head
Restraint, ensure that all cargo is se-
cured, as loose cargo could contact the
Active Head Restraint during sudden
stops. Failure to follow this warning
could cause personal injury if the Active
Head Restraint is deployed.NOTE:
For more information on properly adjusting
and positioning the head restraint, refer to
“Head Restraints” in “Getting To Know Your
Vehicle.”
Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered
during a collision, the front half of the head
restraint will be extended forward and sepa-
rated from the rear half of the head restraint
(See Image). Do not drive your vehicle after

the AHRs have deployed. The head restraint
must be reset into the original position to best
protect the occupant for all types of colli-
sions. An authorized FCA dealer must reset
the AHRs on the driver’s and front passen-
ger’s seat before driving. Personally attempt-
ing to reset the AHRs may result in damage to
the AHRs that could impair their function.
WARNING!
Deployed AHRs are not able to best protect
you in all types of collisions. Have de-
ployed AHRs reset by an authorized dealer
immediately.
Supplemental Restraint Systems (SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect
you in a collision. The Occupant Restraint
Controller (ORC) monitors the internal cir-
cuits and interconnecting wiring associatedwith the electrical Air Bag System Compo-
nents. Your vehicle may be equipped with the
following Air Bag System Components:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
• Steering Wheel and Column
• Instrument Panel
• Knee Impact Bolsters
• Driver and Front Passenger Air Bags
• Seat Belt Buckle Switch
• Supplemental Side Air Bags
• Supplemental Knee Air Bags
• Front and Side Impact Sensors
• Seat Belt Pretensioners
Air Bag Warning Light
The ORC monitors the readiness of the
electronic parts of the air bag system when-
ever the ignition switch is in the START orON/RUN position. If the ignition switch is in
the OFF position or in the ACC position, the
air bag system is not on and the air bags will
not inflate.
The ORC contains a backup power supply
system that may deploy the air bag system
even if the battery loses power or it becomes
disconnected prior to deployment.
The ORC turns on the Air Bag Warning Light
in the instrument panel for approximately
four to eight seconds for a self-check when
the ignition switch is first in the ON/RUN
position. After the self-check, the Air Bag
Warning Light will turn off. If the ORC detects
a malfunction in any part of the system, it
turns on the Air Bag Warning Light, either
momentarily or continuously. A single chime
will sound to alert you if the light comes on
again after initial startup.
The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag
Warning Light if a malfunction is detected
that could affect the air bag system. The
diagnostics also record the nature of the
malfunction. While the air bag system is

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
– Electric park brake
– Automatic transmission gear selector
– Horn
– Front wiper
– Headlamp washer pump

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.
