INSTRUMENT CLUSTER DISPLAY
Your vehicle will be equipped with an instrument cluster
display, which offers useful information to the driver. With
the ignition in the STOP/OFF mode, opening/closing of a
door will activate the display for viewing, and display the
total miles, or kilometers, in the odometer. Your instrument
cluster display is designed to display important information
about your vehicle’s systems and features. Using a driver
interactive display located on the instrument panel, your
instrument cluster display can show you how systems are
working and give you warnings when they are not. The
steering wheel mounted controls allow you to scroll through
the main menus and submenus. You can access the specific
information you want and make selections and adjustments.

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 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.
2020_DT_1500_OM_US.book Page 176

GETTING TO KNOW YOUR INSTRUMENT PANEL 177
NOTE:
• The charging system is independent from load reduction.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 “Getting To Know Your Instru -
ment Panel” for further information.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load reduc -
tion:
• 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, 115V AC, USB ports) during
certain driving conditions (city driving, towing, frequent
stopping).
• 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 w as used for an extended period with t he engine not running to supply radio, lights, chargers,
+12 Volt portable appliances like vacuum cleaners,
gam e 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 Volts,115V AC, USB ports.

• Check HVAC settings (blower, temperature).
• Check the audio settings (volume).
After a trip:
• Check if any aftermarket equipment was installed (addi -
tional 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 instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are indic -
ative 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 tell -
tales 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
— Seat Belt Reminder Warning Light
This warning light indicates when the driver or passenger
seat belt is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and if the driver’s
seat belt is unbuckled, a chime will sound and the light will
turn on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime will sound.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
— 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 spec -
ified level.
