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 [km] 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 distance
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 (53 km) 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 (km) equivalency

Miles (km) driven + miles (km) equivalency = oil change interval

Example: When the odometer has accumulated 3,000 miles (4,800 km)
and the idle meter shows 61 hours, a 5,000 mile (8,000 km) oil change
interval will have been reached: 3,000 road miles (4,800 road km) + (61
idle hours x 33 miles [53 km]/idle hour) = 5,013 miles (8,067 km).
