Diesel Particulate Filter (DPF) Messages
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 inter-
action on your part.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be grass or
leaves coming into contact with your exhaust system. Do
not park or operate your vehicle in areas where your
exhaust system can contact anything that can burn.
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 Highway
Speeds to Clear — This message will be displayed on
the instrument cluster display 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 dis-
played in the instrument cluster display. If this message
is displayed, you will hear one chime to assist in alerting
you of this condition. By simply driving your vehicle at
142 GETTING TO KNOW YOUR INSTRUMENT PANEL

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 Diesel Par-
ticulate Filter (DPF) is self-cleaning. Maintain your cur-
rent driving condition until regeneration is completed.
• Exhaust System — Regeneration Completed — This
message indicates that the Diesel Particulate Filter (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 Pow-
ertrain Control Module (PCM) will register a fault code,
the instrument panel will display a MIL light.
CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation. •
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, extensive exhaust
after-treatment damage can occur. To correct this condi-
tion it will be necessary to have your vehicle serviced by
your local 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 per-
forming it’s 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.
CAUTION!
See your authorized dealer, as damage to the exhaust
system could occur soon with continued operation.

the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
your authorized dealer for service.
• The DEF gauge may also not immediately update after a
refill if the temperature of the DEF fluid is below 12F
(-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period
of run time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill level for
several drives.
Battery Saver On/Battery Saver Mode Message —
Electrical Load Reduction 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. Refer to “Battery
Charge Warning Light” in “Warning And Indicator
146 GETTING TO KNOW YOUR INSTRUMENT PANEL

Lights And Messages” located in ”Getting To Know
Your Instrument Panel” for further information.
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
• Heated/Cooled Cup Holders — If Equipped
• Rear Defroster And Heated Mirrors
• HVAC System
• 115V AC 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 charging system. The
charging system is still functioning properly.
• Turning on all possible vehicle electrical loads (e.g.
HVAC to max settings, exterior and interior lights,
overloaded power outlets +12V, 115V AC, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping). •
Installing options like additional lights, upfitter electri-
cal accessories, audio systems, alarms and similar de-
vices.
• 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,
+12V 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)4
