Touch the “Cleaning Mode” icon button once to momentarily lock
the screen and disable touch controls for 15 seconds, which is long
enough to clean the screen with a soft and lint free microfiber towel.
Do not use chemicals to clean the display�
NOTE
The driver’s position and rear Firefly displays provide some,
but not all of the various control capabilities of the main
display.
WARNING
The Firefly interface and network RV-C CAN Bus is a
sophisticated system that should only be serviced by a
qualified professional. Attempting to use a multi-meter or
other diagnostic tools on the G12 control panel can damage
the sensitive electronics, which may render some or all of
the coach’s equipment inoperable.
■ LIGHTING (INTERIOR AND EXTERIOR)
Your coach is equipped with an array of high quality and efficient
12-volt Light Emitting Diode (LED) light fixtures. All lighting, except
for the front cockpit overhead lighting, is controlled through the Firefly
network interface� Lighting controls are accessible at all three interface
locations (main, front, and rear displays).
Interior lighting is configured into lighting groups, to include the front
reading lights, galley lights, rear reading lights, and accent lights�
Exterior lighting includes individual controls for the awing light strip,
porch light, and the front fog lamps and under coach lighting (if
equipped with these optional features).
Most of the LED lighting fixtures, and the accent lighting strips, do not
have replaceable bulbs� The LED lighting components are durable,
efficient, and will last a very long time. If you need a replacement
assembly, they are available through an American Coach Dealership�
Interior and exterior lighting controlled through the Firefly network
does not have a time out feature similar to that associated with most
automotive interior dome lights� If left on, the lighting will not turn itself
off, which will reduce the life expectancy of the LED fixtures. This
could also draw down the house battery state of charge if the vehicle
is not plugged into shore power�

warning
■ 12 VOLT DC SYSTEM
12-volt power is delivered through two integrated distribution networks
within the vehicle (chassis and house). Chassis 12-volt power is
provided through the Mercedes-Benz chassis’ electrical system and
is generated (primarily) by the 3.0 turbocharged diesel engine’s
alternator� House 12-volt power is provided by one of several means:
the shore power connection, which provides 12-volt power through the
inverter; the Onan LP generator (if equipped); the battery bank (AGM
or Lithium); or, the 3.0 turbocharged diesel engine’s alternator (or a
second under-hood generator if equipped with this option).
The house electrical system is controlled through the coach’s Energy
Management System (EMS), which senses power loads (demand),
and then selects among available power source(s) to provide current
(supply). The EMS uses relays and / or solenoids to select among the
available power sources using the following priority sequence: 1 – the
3.0 turbo diesel engine if it is running; 2 – shore power if the coach is
plugged in; 3 – the Onan LP generator (if equipped); and, 4 – the AGM
or Lithium battery bank�
The Mercedes-Benz Sprinter chassis has its own separate 12-volt
electrical power distribution hub� This electrical distribution hub
provides 12-volt power to the vehicle’s various systems and networks,
to include: 3.0 turbocharged diesel engine management; powertrain
control; chassis lighting; infotainment; steering and braking; and,
passenger safety systems� Please refer to the Mercedes-Benz
Sprinter Operating Instructions for more detailed information on the
location of the various power distribution panels, fuses, and 12-volt
electrical components associated with the chassis� Service of these
components should be performed by a Mercedes-Benz dealership�
■ MASTER DISCONNECT
Power to the 12-volt house distribution hub is controlled by the master
power “Battery” switch, which is located directly below the main Firefly
network interface display� As noted in the previous section on the
Firefly network, the “Battery” switch is either a backlit round button
type (as displayed above in the Firefly section of this chapter) or a red
LED illuminated rocker switch depending on your model� This switch
must be set to “on” whenever you wish to power the Firefly display and
any 12-volt DC electrical loads on the house side of the coach� When
the coach is not in use, especially during periods of long-term storage,
the switch should be set to “off”� The switch may be left “on” when you
are using the coach or are away for brief periods of time� Below is an
image of the illuminated LED rocker style master “Battery” switch�
