VEHICLE STORAGE
If you plan on storing your vehicle for an extended period of time
(30 days or more), refer to the following maintenance recommendations
to ensure your vehicle stays in good operating condition.
All motor vehicles and their components were engineered and tested for
reliable, regular driving. Long term storage under various conditions may
lead to component degradation or failure unless specific precautions are
taken to preserve the components.
General
• Store all vehicles in a dry, ventilated place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they require regular maintenance to
protect against rust and damage.
Body
• Wash vehicle thoroughly to remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing and underside of front fenders.
See the Cleaning chapter for more information.
• Periodically wash vehicles stored in exposed locations.
• Touch-up raw or primed metal to prevent rust.
• Cover chrome and stainless steel parts with a thick coat of auto wax
to prevent discoloration. Re-wax as necessary when the vehicle is
washed. See the Cleaning chapter for more information.Maintenance and Specifications
407

USA (fus)

• Lubricate all hood, door and trunk lid hinges, and latches with a light
grade oil. See the Cleaning chapter for more information.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and solvents.
Engine
• The engine oil and filter should be changed prior to storage, as used
engine oil contain contaminates that may cause engine damage.
• Start the engine every 15 days. Run at fast idle until it reaches normal
operating temperature.
• With your foot on the brake, shift through all the gears while the
engine is running.
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.Maintenance and Specifications

Your dealership recognizes the competitive landscape of maintenance and
light repair automotive services. With factory-trained technicians, and
one-stop service from routine maintenance like oil changes and tire
rotations to repairs like brake service, check out the value your dealers

information and supporting specifications are provided in this owner’s
guide.
Any adverse condition should be brought to the attention of your dealer
or qualified service technician as soon as possible for the proper service
advice. The owner maintenance service checks are generally not covered

EXCEPTIONS
There are several exceptions to the Normal Schedule. They are listed
below:
Normal vehicle axle maintenance: Rear axles and power take-off
(PTO) units with synthetic fluid and light-duty trucks equipped with
Ford-design axles are lubricated for life; do not check or change fluid
unless a leak is suspected, service is required or the assembly has been
submerged in water. During long periods of trailer towing with outside
temperatures above 70°F (21°C) and at wide-open throttle for long
periods above 45 mph (72 km/h), non-synthetic rear axle fluids should
be changed every 3,000 miles (4,800 km) or three months, whichever
comes first. This interval can be waived if the axle is filled with 75W140
synthetic gear fluid meeting Ford specification WSL-M2C192-A, part
number F1TZ-19580-B or equivalent. Add friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles (refer to Maintenance product specifications and capacities in
the Maintenance and Specifications chapter for details).
Police/Taxi/Livery vehicle axle maintenance: Change rear axle fluid
every 100,000 miles (160,000 km). Rear axle fluid change may be waived
if the axle was filled with 75W140 synthetic gear fluid meeting Ford
specification WSL-M2C192-A, part number FITZ-19580-B or equivalent.
Add four ounces (118 mL) of additive friction modifier XL-3
(EST-M2C118-A) or equivalent for complete refill of Traction-Lok rear
axles. The axle fluid should be changed anytime the axle has been
submerged in water
California fuel filter replacement: If the vehicle is registered in
California, the California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify the emission
warranty or limit recall liability prior to the completion of the vehicle’s
useful life. Ford Motor Company, however, urges you to have all
recommended maintenance services performed at the specified intervals
and to record all vehicle service.
Class A Motorhome: Change brake fluid every two years.
Hot climate oil change intervals: Vehicles operating in the Middle
East, North Africa, Sub-Saharan Africa or locations with similar climates
using an American Petroleum Institute (API) Certified for Gasoline
Engines (Certification mark) oil of SM or SN quality, the normal oil
change interval is 5,000 miles (8,000 km).
If the available API “SM” or “SN” oils are not available, then the oil
change service interval is 3,000 mile (4,800 km).Scheduled Maintenance
