Analog Indicators - PREVOST H3-45 VIP Owner's Manual

ANALOG INDICATORS

Tachometer (Rpm X 100)
Indicates the operating speed of the engine in hundreds of revolutions
per minute. The tachometer serves as a guide for gear shifting and helps
to prevent engine over-speeding when driving downhill with the engine
brake operating. Use the green range for normal driving (1000 to 1600
RPM).
CAUTION
Never allow the engine to go into the red range. This could lead to
severe engine damage.
Speedometer (MPH, Km/h)
Indicates the vehicle speed in miles per hour (mph) and kilometers per
hour (km/h). The LEDs above the instrument work in conjunction with
AWARE Adaptive Cruise Braking (ACB) system. Refer to "Prevost
Aware Adaptive Cruise Braking" paragraph for further details.
Turbo Boost Pressure (psi)
Indicates the turbo boost pressure in psi. This pressure should be the
same at a given engine temperature, speed, and load. An unusual reading
could indicate an engine failure.
