2018 Ram 2500 battery

A key symbol indicates that the key must be in the
ON/RUN or ACC positions for the outlet to provide
power. The battery symbol indicates that the outlet is
connected to the battery, and can provide power at all
times.
NOTE:To ensure proper operation, a Mopar knob and
element must be used.
CAUTION!
•Do not exceed the maximum power of 160 Watts
(13 Amps) at 12 Volts. If the 160 Watts (13 Amps) 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. The auxiliary power outlets can be found in the following
locations:
•
Lower left and lower right of the center stack when
equipped with a bench seat.
Power Outlets — Center Stack
1 — Power Outlet
2 — USB Port (Charge Only)

When the vehicle is turned off, be sure to unplug any
equipment as to not drain the battery of the vehicle. All
accessories connected to the outlet(s) should be removed or
turned off when the vehicle is not in use to protect the
battery against discharge.

WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
CAUTION!
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery even more quickly. Only use these intermit-
tently and with greater caution.
(Continued)
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.

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.

CAUTION!
Leaving the lid open for extended periods of time
could cause the vehicle battery to discharge. If the lid
is required to stay open for extended periods of time, it
is recommended that the bin lights be turned off
manually using the on/off switch.
The interior of the RamBox will automatically illuminate
when the lid is opened. In addition to the automatic
illumination switch, there is a manual on/off switch lo-
cated at the rear of each storage bin. Pushing the switch
once will turn off the bin lights, pushing the switch again
will turn the lights back on. Cargo bins feature two removable drain plugs (to allow
water to drain from bins). To remove plug, pull up on the
edge. To install push plug downward into drain hole.

Premium Instrument Cluster Descriptions
1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Voltmeter •When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay
within the normal range if the battery is charged. If the
pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
NOTE: The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold heater
system. The number of cycles and the length of the cycling
operation is controlled by the engine control module.
Post-heat operation can run for several minutes, and then
the electrical system and voltmeter needle will stabilize.
3. Oil Pressure Gauge
•The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
4. Speedometer •Indicates vehicle speed.
5. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
6. Instrument Cluster Display
•When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
7. Temperature Gauge •The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
