ODE MESSAGE — ELECTRICAL LOAD
R
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 Some Systems May Have
Reduced Power” will appear in the instrument
cluster. 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
reduction. The charging system performs a diag
-
nostic on the charging system continuously.
If the Battery Charge Warning Light is on it may
indicate a problem with the charging system
Ú page 129.
The electrical loads that may be switched off
(if equipped), and vehicle functions which can be
affected by load reduction:
Heated Seats / Vented Seats / Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volts 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 +12 Volts,
115 Volts AC, USB ports) during certain driving
conditions (city driving, towing, frequent stop -
ping).
Installing options like additional lights, upfitter
electrical 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 cleaners, 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 exte -
rior).
Check what may be plugged in to power
outlets +12 Volts, 115 Volts AC, 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.
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 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 either 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.

Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.

146STARTING AND OPERATING
NORMAL OPERATION — DIESEL ENGINE
Observe the following when the diesel engine is
operating.
All message center lights are off.
Malfunction Indicator Light (MIL) is off.
Engine Oil Pressure telltale is not illuminated.
Voltmeter operation:
The voltmeter may show a gauge fluctuation at
various engine temperatures. This is caused by the
glow plug heating system. The number of cycles
and the length of the cycling operation is controlled
by the engine control module. Glow plug heater
operation can run for several minutes, once the
heater operation is complete the voltmeter needle
will stabilize.
COLD WEATHER PRECAUTIONS
Operation in ambient temperature below 32°F
(0°C) may require special considerations. The
following charts suggest these options:
Fuel Operating Range
NOTE:Use Ultra Low Sulfur Diesel (ULSD) Fuels ONLY.

Fuel Operating Range Chart

*Number 1 ULSD Fuel should only be used where
extended arctic conditions below (0°F/-18°C)
exist.
NOTE:
Use of Climatized ULSD Fuel or Number 1 ULSD
Fuel results in a noticeable decrease in fuel
economy.
Climatized ULSD Fuel is a blend of Number 2
ULSD and Number 1 ULSD Fuels which reduces
the temperature at which wax crystals form in
fuel.
The fuel grade should be clearly marked on the
pump at the fuel station.
The engine requires the use of ULSD Fuel. Use
of incorrect fuel could result in engine and
exhaust system damage Ú page 469.
If Climatized or diesel Number 1 ULSD Fuel is
not available, and you are operating below
(20°F/-6°C), in sustained arctic conditions,
Mopar® Premium Diesel Fuel Treatment (or
equivalent) is recommended to avoid gelling
(see Fuel Operating Range Chart).
Engine Oil Usage
