Engine Idle Hour Meter
Your vehicle may been fitted with an idle
meter to indicate how much time the
vehicle has been sitting in park (P) or
neutral (N). The meter is incorporated with
the vehicle odometer. Depressing the
odometer-reset button once displays the
trip odometer (miles [kilometers]
following by a "T" for trip odometer);
depressing the odometer-reset button a
second time displays the idle meter (hours
following by an "H" for hours). The idle
meter only accumulates time when the
vehicle is in park (P) or neutral (N). Displayed time is cumulative for the vehicle
and cannot be reset to zero. Police vehicles
often experience long periods of idling,
during which engine oil continues to break
down but distance is not accumulated on
the odometer.
Engine idle hour meter calculation:
Idle hours x 33 = miles (kilometers)
equivalency
Miles (kilometers) driven + miles
(kilometers) equivalency = oil change
