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).

Middle East hot climate specifications
❑If operating conditions are normal and you drive your vehicle under typical, everyday conditionsandyou are using an API
performance category oil of SL or later (for example SM, etc.) then you can follow the 7,500 mile (12,000 km) normal
service oil change intervals schedule. Vehicles operating in the Middle East, North Africa, Sub-Saharan Africa or locations with
similar climates must follow the oil change interval of 3,000 mile (4,800 km) if the owner is using oils defined by the
American Petroleum Institute (API) performance category of API SK or earlier (for example SJ, etc.).
❑Edge/MKX AWD only– vehicles operating off-road in sand during high ambient temperatures must replace the AWD
PTU (All-wheel drive Power Transfer Unit) lube every 20,000 miles (32,000 km).
Engine air filter & cabin air filter replacement
❑Engine air filter and cabin air filter life is dependent on exposure to dusty and dirty conditions. Vehicles operated in these
conditions will require frequent inspection and replacement of the engine air filter and cabin air filter.
