How fail-safe cooling works
If the engine begins to overheat:
•The engine coolant temperature gauge will move to the red (hot)
area.
•The coolant temperature warning light
will illuminate.
•The service engine soon
indicator will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
•The engine power will be limited.
•The air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase.
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
WARNING:Fail-safe mode is for use during emergencies only.
Operate the vehicle in fail-safe mode only as long as necessary to
bring the vehicle to rest in a safe location and seek immediate repairs.
When in fail-safe mode, the vehicle will have limited power, will not be
able to maintain high-speed operation, and may completely shut down
without warning, potentially losing engine power, power steering assist,
and power brake assist, which may increase the possibility of a crash
resulting in serious injury.

4. After you are done pumping fuel, wait about five seconds before
slowly removing the fuel filler nozzle. This allows residual fuel to drain
back into the fuel tank and not spill onto the vehicle.
Note:A fuel spillage concern may occur if overfilling the fuel tank. Do
not overfill the tank to the point that the fuel is able to bypass the fuel
filler nozzle. The overfilled fuel may run down the drain located within
the fuel filler housing and to the ground.
If the check fuel fill inlet light or CHECK FUEL FILL INLET message
comes on, the fuel fill inlet may not have properly closed. The inlet may
have stuck open or debris may be preventing the inlet from fully closing.
At the next opportunity, safely pull off the road, turn off the engine,
open the fuel filler door and remove any visible debris from the fuel fill
opening. Insert either the fuel fill nozzle or the fuel fill funnel (see
Refilling with a portable fuel containerfor funnel location) provided
with the vehicle several times to dislodge any debris and/or allow the
inlet to close properly. If this action corrects the problem, the check fuel
fill inlet light or CHECK FUEL FILL INLET message may not reset
immediately. It may take several driving cycles for the check fuel fill inlet
light or CHECK FUEL FILL INLET message to turn off. A driving cycle
consists of an engine start-up (after four or more hours with the engine
off) followed by city/highway driving. Continuing to drive with the check
fuel fill inlet light or CHECK FUEL FILL INLET message on may cause
the service engine soon lamp to turn on as well.
WARNING:The fuel system may be under pressure. If you hear
a hissing sound near the fuel filler door (Easy Fuel™ “no cap”
fuel system), do not refuel until the sound stops. Otherwise, fuel may
spray out, which could cause serious personal injury.
Choosing the right fuel
Use only UNLEADED fuel or UNLEADED fuel blended with a maximum
of 10% ethanol. Do not use fuel ethanol (E85), diesel, methanol, leaded
fuel or any other fuel. The use of leaded fuel is prohibited by law and
could damage your vehicle.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based additives.
Note:Use of any fuel other than those recommended may cause
powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.

grade oil. See theCleaningchapter 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 MotorcraftGas Stabilizer or
equivalent meeting Ford material specification ESE-M99C112-A 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.

EXCEPTIONS
In addition, there are several exceptions to the Normal Schedule. They
are listed below:
Normal vehicle axle maintenance
❑Rear axles and power take-off (PTO) units containing synthetic lubricant and light duty trucks equipped with Ford-design
axles are lubricated for life. These lubricants are not to be checked or changed unless a leak is suspected, service is re-
quired or the axle assembly has been submerged in water. The axle and PTO lubricant should be changed anytime the axle
and PTO have been submerged in water. During extended trailer tow operation above 70°F (21°C) ambient and wide open
throttle for extended periods above 45 mph (72 km/h), non-synthetic rear axle lubricants should be replaced every
3,000 miles (4,800 km) or three months, whichever occurs first. The 3,000 mile (4,800 km) lubricant change interval
may be waived if the axle was filled with 75W140 synthetic gear lubricant 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 and specificationsin theMaintenance and Specificationschapter for details).
The axle lubricant should be changed anytime an axle has been submerged in water.
Police/Taxi/Livery vehicle axle maintenance
❑Replace rear axle lubricant every 100,000 miles (160,000 km). Rear axle lubricant change may be waived if the axle
was filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part number FITZ-19580-B or
equivalent. Add four ounces (118 mL) of friction modifier XL-3 (EST-M2C118-A) or equivalent for complete refill of Traction-
Lok rear axles. The axle lubricant should be changed anytime the axle has been submerged in water.
California fuel filter replacement
❑If vehicle is registered in California, the California Air Resources Board has determined that the failure to perform this main-
tenance 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 inter-
vals and to record all vehicle service.
Hot climate oil change intervals
❑If operating conditions are normal and you drive your Ford, Lincoln or Mercury vehicle under typical, everyday conditions
andyou 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 (5,000 km) if the
owner is using oils defined by the American Petroleum Institute (API) performance category of API SK or earlier (for ex-
ample SJ, etc.).
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.
