OPERATING INSTRUCTIONS
DASH SWITCHES
This custom vehicle will have a wide variety of switch controlled equipment.
However, this particular vehicle may not have every switch identified in
this section of the operator manual.
Some air device switches on the dash may require that the vehicle either
be at a specific speed, parking brakes set or another device to be on or
off for the air device to operate.
The instrument display will display information regarding what needs to
change in order for the air device to operate as expected.
Some of these switches control air system functions and may require the
vehicle’s ignition to be in the ACC or ON position for switch to maintain
control via air pressure. If the switch requires ignition power, it will allow
that air circuit to lose pressure (deactivate) once the ignition is turned
OFF. To activate that function again, the ignition needs to be turned to
the ACC or ON position and the switch needs to be re-engaged. Some of
the switches that control air functions will not disengage when the vehicle
ignition is turned off.
If the ignition is turned off, air pressure will be maintained in the circuit for
that control switch. The few switches that do not require ignition power
are described accordingly after the Dash Switch table.
The Dash Switch table provides a complete list of icons that may be found
on the switch.
