2018 Ram 4500 Chassis Cab AUX

NOTE:
• Driving conditions (altitude, vehicle speed,load, etc.) will effect the amount of DEF that
is used in your vehicle.
• Another factor is that outside temperature can affect DEF consumption. In cold condi-
tions, 12° F (-11° C) and below, the DEF
gauge needle can stay on a fixed position
and may not move for extended periods of
time. This is a normal function of the sys-
tem.
• Since DEF will begin to freeze at 12°F (-11°C), your vehicle is equipped with an
automatic DEF heating system. This allows
the DEF injection system to operate properly
at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended
period of time with temperatures below 12°F
(-11°C), the DEF in the tank may freeze. If
the tank is overfilled and freezes, it could be
damaged. Therefore, do not overfill the DEF
tank. Extra care should be taken when filling
with portable containers to avoid overfilling.
Note the level of the DEF gauge in your
instrument cluster. On pickup applications, you may safely add a maximum of 2 gallons
(7.5 liters) of DEF from portable containers
when your DEF gauge is reading ½ full. On
Chassis Cab applications, a maximum of
2 gallons (7.5 liters) may be added when the
DEF gauge is reading ¾ full.
• There is an electric heater inside the DEF tank that automatically works when neces-
sary. And if the DEF supply does freeze, the
truck will operate normally until it thaws.
• Ensure the DEF cap is reinstalled prior to filling vehicle with diesel fuel to avoid spill-
ing diesel fuel into the DEF Filler.
AUXILIARY SWITCHES
There can be up to five auxiliary switches lo-
cated in the lower switch bank of the instru-
ment panel, which can all be used to power
various electronic devices and PTO (Power Take
Off) – if equipped. Connections to the switches
are found under the hood in the connectors
attached to the auxiliary Power Distribution
Center. The system has the ability to configure the
functionality of the auxiliary switches via the
Instrument Cluster Display. All switches can
now be configured for ignition or battery power,
saving or not saving the state across a key cycle,
and momentary or latching switch operation.
For further information on using the auxiliary
switches, please refer to the Ram Body Builders
