Switches - Holiday Navigator 2003 Owner's Manual

AIR PRESSURE GAUGE:
Uses two needles to indicate air system pressures. One needle indicates air
pressure of the front air tank. The other needle indicates air pressure
of the rear air tank. The normal air system operating pressures are 105
to 120 psi. These air pressures are preset at the factory. If a problem
occurs with either air system not maintaining normal operating pressure,
it is an indication of a malfunction in the air system. Use caution and
stop the motorhome in a safe area. Contact your dealer immediately.
NOTE: It is not safe to drive the motorhome with low
air pressure. Damage can occur to the suspension and
driveline, also affecting operation of the air brake
system.
VOLTMETER:
Shows the charge condition in the chassis battery. The normal voltage
with the ignition switch ON and the engine OFF varies between
12.0 and 13 Volts. With the engine operating without a heavy load,
the battery charging voltage is about 14.0 Volts. Battery readings of
less than 10.5, or more than 15 Volts, usually indicates a battery or
electrical system problem.
TURBO BOOST:
Indicates boost pressure produced by the engine turbocharger.
NOTE: Layouts may vary with difference in models
or options.
AIR DUMP:
Deflates air suspension (Hydraulic Leveling only).
AQUA-HOT (Optional):
Turns the Aqua-Hot diesel burner on.
ATC:
Activating the ATC switch allows greater engine torque during an ATC
event.
