• There is an electric heater inside the DEFtank 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 located
in the lower switch bank of the instrument 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
