EDUCTION ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent Battery Sensor
(IBS) to perform additional monitoring of the electrical
system and status of the vehicle battery.
In cases when the IBS detects charging system failure, or
the vehicle battery conditions are deteriorating, electrical
load reduction actions will take place to extend the driving
time and distance of the vehicle. This is done by reducing
power to or turning off non-essential electrical loads.
Load reduction is only active when the engine is running.
It will display a message if there is a risk of battery
depletion to the point where the vehicle may stall due to
lack of electrical supply, or will not restart after the current
drive cycle.

When load reduction is activated, the message “Battery
Saver On” or “Battery Saver Mode” will appear in the
instrument cluster display.
These messages indicate the vehicle battery has a low
state of charge and continues to lose electrical charge at
a rate that the charging system cannot sustain.
NOTE:
The charging system is independent from load reduc -
tion. The charging system performs a diagnostic on the
charging system continuously.
 If the Battery Charge Warning Light is on it may indicate
a problem with the charging system
Úpage 117.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be effected by load
reduction:
 Heated Seat/Vented Seats/Heated Wheel
 Rear Defroster And Heated Mirrors
 HVAC System
 150W Power Inverter System
 Audio and Telematics System
Loss of the battery charge may indicate one or more of the
following conditions:
 The charging system cannot deliver enough electrical
power to the vehicle system because the electrical
loads are larger than the capability of the charging
system. The charging system is still functioning prop -
erly.
 Turning on all possible vehicle electrical loads (e.g.
HVAC to max settings, exterior and interior lights, over -
loaded power outlets +12 Volt, 150W, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping). 
Installing options like additional lights, upfitter elec -
trical accessories, audio systems, alarms and similar
devices.
 Unusual driving cycles (short trips separated by long
parking periods).
 The vehicle was parked for an extended period of time
(weeks, months).
 The battery was recently replaced and was not charged
completely.
 The battery was discharged by an electrical load left on
when the vehicle was parked.
 The battery was used for an extended period with the
engine not running to supply radio, lights, chargers,
+12 Volt portable appliances like vacuum cleaner’s,
game consoles and similar devices.
What to do when an electrical load reduction action
message is present (“Battery Saver On” or “Battery Saver
Mode”)
During a trip:
 Reduce power to unnecessary loads if possible:
 Turn off redundant lights (interior or exterior)
 Check what may be plugged in to power outlets
+12 Volt, 150W, USB ports
 Check HVAC settings (blower, temperature)
 Check the audio settings (volume)
After a trip:
 Check if any aftermarket equipment was installed
(additional lights, upfitter electrical accessories, audio
systems, alarms) and review specifications if any (load
and Ignition Off Draw currents). 
Evaluate the latest driving cycles (distance, driving
time and parking time).
 The vehicle should have service performed if the
message is still present during consecutive trips and
the evaluation of the vehicle and driving pattern did not
help to identify the cause.

ESSAGES
This engine meets all required diesel engine emissions
standards. To achieve these emissions standards, your
vehicle is equipped with a state-of-the-art engine and
exhaust system. These systems are seamlessly integrated
into your vehicle and managed by the Powertrain Control
Module (PCM). The PCM manages engine combustion to
allow the exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input or
interaction on your part.

116GETTING TO KNOW YOUR INSTRUMENT PANEL
Your vehicle has the ability to alert you to additional
maintenance required on your vehicle or engine. Refer to
the following messages that may be displayed on your
instrument cluster display:
Exhaust Filter Nearing Full Safely Drive at Consistent
Speeds to Clear — This message will be displayed if the
exhaust particulate filter reaches 80% of its maximum
storage capacity. Under conditions of exclusive short
duration and low speed driving cycles, your diesel
engine and exhaust after-treatment system may never
reach the conditions required to cleanse the filter to
remove the trapped PM. If this occurs, the “Exhaust Filter XX% Full Safely Drive at Highway Speeds to
Remedy” message will be displayed. If this message is
displayed, you will hear one chime to assist in alerting
you of this condition. By simply driving your vehicle at
highway speeds for up to 20 minutes, you can remedy
the condition in the particulate filter system and allow
your diesel engine and exhaust after-treatment system
to cleanse the filter to remove the trapped PM and
restore the system to normal operating condition.
 Exhaust System Regeneration in Process Continue
Driving — This message indicates that the DPF is
self-cleaning. Maintain your current driving condition
until regeneration is completed.
 Exhaust System — Regeneration Completed — This
message indicates that the DPF self-cleaning is
completed. If this message is displayed, you will hear
one chime to assist in alerting you of this condition.
 Exhaust System Service Required — See Dealer — This
messages indicates regeneration has been disabled
due to a system malfunction. At this point the engine
Powertrain Control Module (PCM) will register a fault
code, the instrument panel will display a Malfunction
Indicator Light (MIL).
 Exhaust Filter Full — Power Reduced See Dealer — This
message indicates the PCM has derated the engine to
limit the likelihood of permanent damage to the
after-treatment system. If this condition is not
corrected and a dealer service is not performed, exten -sive 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 (0 kilo
-
meters) remaining will prevent the diesel exhaust filter
from performing its cleaning routine. This will shortly result
in a Malfunction Indicator Light (MIL) and reduced engine
power. Only an authorized dealer will be able to correct
this condition.
FUEL SYSTEM MESSAGES
The following chart contains a list of different messages
that may appear in the instrument cluster, depending on
different system or fuel conditions. Use the descriptions to
interpret what the message means and determine the
best action to take.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated message and/
or acoustic signal when applicable. These indications are
indicative and precautionary and as such must not be
considered as exhaustive and/or alternative to the
information contained in the Owner’s Manual, which you
are advised to read carefully in all cases. Always refer to
WARNING!
A malfunctioning catalytic converter, as previously
referenced, can reach higher temperatures than in
normal operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such as
dry plants, wood, cardboard, etc. This could result in
death or serious injury to the driver, occupants or
others.
CAUTION!
The engine may be switched off even if the warning
light is on: repeated interruptions of the regeneration
process could cause an early deterioration of engine oil.
For this reason it is always advisable to wait for the

The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The
vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
