ENGINE IDLE HOUR METER (IF EQUIPPED):
Your vehicle may be equipped with an idle meter to indicate how much time the vehicle is idling in P (Park)
or N (Neutral). The meter is incorporated with the vehicle odometer. Depressing the odometer-reset button
once will display the trip odometer (miles followed by a “T” for trip odometer). Depressing the odometer-reset
button a second time will display the idle meter (hours followed by an “H” for hours). The idle meter
only accumulates time when the vehicle is in P (Park) or N (Neutral). Displayed time is cumulative for the
vehicle.It cannot be reset to zero.
Police/Fleet vehicles often experience long periods of idling,
during which engine oil will continue to break down but mileage is not accumulated on the odometer.
To assist fleet managers in maintaining proper oil change intervals, the idle meter will help determine when
an oil change is required. For every hour that the vehicle idles, it has accumulated the equivalent of
approximately 33 miles of driving. Using the combination of the vehicle odometer and idle meter allows
the fleet manager to better determine when the oil needs to be changed
Engine idle hour meter calculation:
Idle hours x 33 = miles equivalency
Miles driven + miles equivalency = oil change interval
Example:When the odometer has accumulated 3,000 miles and the idle meter shows 61 hours, a
5,000 mile oil change interval will have been reached: 3,000 road miles + (61 idle hours x 33 miles/idle
hour) = 5,013 miles.
