1. Air Pressure Gauge : This gauge uses two needles to indicate air system pressures. One nee-
dle 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 90 to 120 psi. These air pressures are pre-
set 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 drive line, also affecting operation of the air brake sys-
tem.
2. Coolant Temp: Under average conditions the gauge will read between 180° F and 205° F.
Monitor this gauge frequently when CLIMBING HILLS, TOWING OR IN HIGH AMBIENT
TEMPERATURES. If the gauge shows that an over-heating condition exists (the needle moving
above the 212° F area), IMMEDIATE ACTION should be taken to avoid engine damage.
Overheating may be a result of any of the following conditions:
• Low coolant level.
• Hydraulic fan motor failure.
• Mechanical failure of hoses or belts.
• Blocking of charge air cooler fins.
• Climbing a long hill on a hot day.
• Towing a heavy trailer.
• Idling for long periods of time.
