or steering wheel if equipped.
OPERATING TIPS
Refer to the chart at the end of this section for suggested
control settings for various weather conditions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling system is
functioning properly and the proper amount, type, and concentration of coolant is used. Use of the Air
Recirculation mode during Winter months is not
recommended, because it may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control system
when the vehicle is being stored for an extended period of
time, see
Úpage 359.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select
Defrost or Mix mode and increase the front blower speed.
Do not use the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions, such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
Winter months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The Climate Control system filters out dust and pollen
from the air. Contact an authorized dealer to service your
cabin air filter, and to have it replaced when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control system may
automatically adjust airflow to maintain cabin comfort.

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.

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
symbol to go off before turning off the engine, following
the previously mentioned instructions. Do not complete
the DPF regeneration process when the vehicle is
stopped.
CAUTION!
See an authorized dealer, as damage to the exhaust
system could occur soon with continued operation.

the information in this chapter in the event of a failure
indication. All active telltales will display first if applicable.
The system check menu may appear different based upon
equipment options and current vehicle status. Some
telltales are optional and may not appear.
RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for four to
eight seconds as a bulb check when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position. This light will illuminate with a single chime
when a fault with the air bag has been detected, it will stay
on until the fault is cleared. If the light is not on during
startup, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as
possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake light
turns on it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is
a problem with the Anti-Lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake,
and a brake pedal pulsation may be felt during each stop.
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
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is applied. It
does not show the degree of brake application.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Contact
an authorized dealer as soon as possible.
This indicates a possible problem with the electrical
system or a related component.
Door Open Warning Light
This indicator will illuminate when a door is
ajar/open and not fully closed.
NOTE:If the vehicle is moving, there will also be a single chime.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.
