2018 Ram 4500 Chassis Cab battery

CAUTION!(Continued)
•After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the generator to
recharge the vehicle’s battery.
Cigar Lighter And Ash Receiver — If Equipped
A removable cigar lighter and ash receiver are available.
For vehicles with a bench seat, the cup holder tray can be
used to hold the ash receiver.
Power Inverter — If Equipped
A 115 or 230 Volt (150 Watts Maximum) outlet is located on
the center stack of the instrument panel, to the right of the
radio. This outlet can power cellular phones, electronics
and other low power devices requiring power up to 150
Watts. Certain high-end video game consoles will exceed
this power limit, as will most power tools.
The power inverter is designed with built-in overload
protection. If the power rating of 150 Watts is exceeded, the
power inverter will automatically shut down. Once the
electrical device has been removed from the outlet the
inverter should automatically reset. To turn on the power outlet, simply plug in the device. The
outlet automatically turns off when the device is un-
plugged.
NOTE:
•
The Power Inverter will only turn on if the ignition is in
the ACC or ON/RUN position
• Due to built-in overload protection, the power inverter
will shut down if the power rating is exceeded.

WARNING!
To avoid serious injury or death:
•Do not insert any objects into the receptacles.
• Do not touch with wet hands.
• Close the lid when not in use.
• If this outlet is mishandled, it may cause an electric
shock and failure.
Auxiliary Switches — If Equipped
There can be up to five auxiliary switches located in the
lower switch bank of the instrument panel which can be
used to power various electronic devices and PTO (Power
Take Off) – If Equipped. If Power Take Off is equipped, it
will take the place of the fifth Auxiliary switch. Connec-
tions to the switches are found under the hood in the
connectors attached to the auxiliary Power Distribution
Center. You have the ability to configure the functionality of the
auxiliary switches via the instrument cluster display. All
switches can now be configured for setting the switch type
operation to latching or momentary, power source of either
battery or ignition, and ability to hold last state across key
cycles.
NOTE:
Holding last state conditions are met when switch
type is set to latching and power source is set to ignition.
For further information on using the auxiliary switches,
please refer to the Ram Body Builders Guide by accessing
www.rambodybuilder.com and choosing the appropriate
links.

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.
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 “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 affected by load
reduction:
• Heated Seat/Vented Seats/Heated Wheel
• Heated/Cooled Cup Holders — If Equipped
• Rear Defroster And Heated Mirrors
• HVAC System
148 GETTING TO KNOW YOUR INSTRUMENT PANEL

•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 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 exterior)
– Check what may be plugged in to power outlets +12V, 115V AC, USB ports
– Check HVAC settings (blower, temperature)
– Check the audio settings (volume)
After a trip:
• Check if any aftermarket equipment was installed (ad-
ditional lights, upfitter electrical accessories, audio sys-
tems, alarms) and review specifications if any (load and
Ignition Off Draw currents).
