POWER INVERTERS — IF EQUIPPED
There is a 115 V (400 W) maximum inverter outlet
located on the back of the center console to
convert Direct Current (DC) to Alternating Current
(AC).
This outlet can power cellular phones, electronics
and other low power devices requiring power up to
400 W. Certain video game consoles exceed this
power limit, as will most power tools.
Power Inverter

There may also be a second 115 V (400 W)
maximum exterior power inverter located on the
rear right side of the truck bed near the tailgate.
This inverter can be turned on by the Instrument
Panel Power Inverter switch located to the left of
the steering wheel. This inverter can power cellular
phones, electronics and other low power devices
requiring power up to 400 W. Certain video game
consoles exceed this limit, as will most power
tools. The indicator light on the power inverter
switch will be illuminated when the inverter is
turned on.
CAUTION!
Do not exceed the maximum power of 160 W
(13 A) at 12 Volts. If the 160 W (13 A) power
rating is exceeded, the fuse protecting the
system will need to be replaced.
Power outlets are designed for accessory
plugs only. Do not insert any other object in
the power outlets as this will damage the
outlet and blow the fuse. Improper use of the
power outlet can cause damage not covered
by your New Vehicle Limited Warranty.
Many accessories that can be plugged in draw
power from the vehicle's battery, even when
not in use (i.e., cellular phones, etc.). Eventu -
ally, if plugged in long enough, the vehicle's
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
Accessories that draw higher power (i.e.,
coolers, vacuum cleaners, lights, etc.), will
degrade the battery even more quickly. Only
use these intermittently and with greater
caution.
After the use of high power draw accessories,
or long periods of the vehicle not being started
(with accessories still plugged in), the vehicle
must be driven a sufficient length of time to
allow the alternator to recharge the vehicle's
battery.
Power outlets are designed for accessory
plugs only. Do not hang any type of accessory
or accessory bracket from the plug. Improper
use of the power outlet can cause damage.

ODE MESSAGE, AND ELECTRICAL
L
OAD REDUCTION ACTIONS
(I
F 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 133.
The electrical loads that may be switched off (if
equipped), and vehicle functions which can be
affected by load reduction:
Heated Seat/Vented Seats/Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volt AC Power Inverter System
Audio and Telematics System
Loss of 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 properly.
Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and interior
lights, overloaded power outlets +12 Volt,
115 Volt 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 Volt, 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.
DIESEL DISPLAYS
When the appropriate conditions exist, the
following messages display in the instrument
cluster display:
Exhaust Filter Nearing Full Safely Drive at

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.
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.

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 not on during startup,
stay 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.
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.

instrument cluster will come on when the
ignition is placed in the ON/RUN or ACC/ON/RUN
position, and when ESC is activated. It should go
out with the engine running. If the ESC Indicator
Light comes on continuously with the engine
running, a malfunction has been detected in the
ESC system. If this warning light remains on after
several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater
than 30 mph (48 km/h), see an authorized dealer
as soon as possible to have the problem
diagnosed and corrected.
The ESC OFF Indicator Light and the ESC Indi -
cator Light come on momentarily each time the
ignition is placed in the ON/RUN or ACC/ON/
RUN position.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive.
This light will come on when the vehicle is in an
ESC event.
WARNING!
