You can also check the fluid level by looking at the see-through plastic
reservoir. Make sure that the fluid is within the minimum and maximum
fluid range as marked on the reservoir.
FUEL FILTER
Gasoline Engine
Your vehicle is equipped with a lifetime fuel filter that is part of the fuel
tank. You do need to perform regular maintenance or replace it.
Diesel Engine
WARNING: Do not drain water separator while engine is
running. Fuel may ignite if separator is drained while engine is
running or vehicle is moving.
The fuel filter water separator removes any contaminated particles and
water from the fuel before the fuel enters the engine.
See your engine operator’s manual for information on draining and
replacing the fuel filter.
WASHER FLUID CHECK
WARNING: If you operate your vehicle in temperatures below
40°F (5°C), use washer fluid with antifreeze protection. Failure
to use washer fluid with antifreeze protection in cold weather could
result in impaired windshield vision and increase the risk of injury or
accident.
Add fluid to fill the reservoir if the level is low. Only use a washer fluid
that meets Ford specifications. See Technical specifications in the
Capacities and Specifications chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive. Only
use washer fluids containing non-methanol antifreeze agents if they
provide cold weather protection without damaging your vehicle’s paint
finish, wiper blades or washer system.
