Fuel system
•Fill the fuel tank with high-quality fuel until the first automatic shutoff
of the fuel pump nozzle.
Note:During extended periods of vehicle storage (30 days or more),
fuel may deteriorate due to oxidation. Add a quality gas stabilizer
product to the vehicle fuel system whenever actual or expected storage
periods exceed 30 days. Follow the instructions on the additive label.
The vehicle should then be operated at idle speed to circulate the
additive throughout the fuel system.
Cooling system
•Protect against freezing temperatures.
•When removing vehicle from storage, check coolant fluid level.
Confirm there are no cooling system leaks, and fluid is at the
recommended level.
Battery
•Check and recharge as necessary. Keep connections clean.
•If storing your vehicle for more than 30 days without recharging the
battery, it may be advisable to disconnect the battery cables to ensure
battery charge is maintained for quick starting.
Note:If battery cables are disconnected, it will be necessary to reset
memory features.
Brakes
•Make sure brakes and parking brake are fully released.
Tires
•Maintain recommended air pressure.
Miscellaneous
•Make sure all linkages, cables, levers and pins under vehicle are
covered with grease to prevent rust.
•Move vehicles at least 25 feet (8 m) every 15 days to lubricate
working parts and prevent corrosion.

scheduled maintenance interval to help ensure your vehicle keeps
running great.
Multi-point inspection – Recommended each visit
Accessory drive belt(s) Half-shaft dust boots (if equipped)
Battery performance Horn operation
Clutch operation (if equipped) Radiator, cooler, heater and A/C hoses
Engine air filter Suspension component for leaks or
damage
Exhaust system Steering and linkage
Exterior lamps and hazard
warning system operationTires for wear and proper pressure,
including spare
Fluid levels*; fill if necessary Windshield for cracks, chips or pits
For oil and fluid leaks Washer spray and wiper operation
*Brake, coolant recovery reservoir, manual and automatic transmission
(with an underhood dipstick), power steering (if equipped) and
window washer
Be sure to ask your dealership service advisor or technician about the
multi-point vehicle inspection. It’s a comprehensive way to perform a
thorough inspection of your vehicle. It’s your checklist that gives you

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 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.
