Class A Motorhome: Change brake fluid every two years.
Hot climate oil change intervals: If operating conditions are normal
and you drive your vehicle under typical, everyday conditions and you
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
