WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets
Ford specifications. Do not use any
special washer fluid such as
windshield water repellent type fluid
or bug wash. They may cause
squeaking, chatter noise, streaking
and smearing. Refer to
Maintenance product
specifications and capacities in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
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.
CHANGING THE WIPER BLADES
1. Pull the wiper arm away from the
vehicle. Pry open the lock cover
with your thumb (1) to release the
blade and pull the wiper blade down
toward the windshield to remove it
from the arm (2).
2. Insert the wiper arm hook into
the wiper arm (3).
3. While holding the wiper arm,
push the wiper blade up and away from the windshield.
4. Close the lock cover.

To protect your engine and engine’s warranty, use Motorcraft  SAE
5W-20 or an equivalent SAE 5W-20 oil meeting Ford specification
WSS-M2C945-A. SAE 5W-20 oil provides optimum fuel economy and
durability performance meeting all requirements for your
vehicle’s engine. Refer to Maintenance product specifications and
capacities later in this chapter for more information.
Do not use supplemental engine oil additives, cleaners or other engine
treatments. They are unnecessary and could lead to engine damage that
is not covered by Ford warranty.
Change your engine oil and filter according to the appropriate schedule
listed in the scheduled maintenance information.
Ford production and Motorcraft  replacement oil filters are designed for
added engine protection and long life. If a replacement oil filter is used
that does not meet Ford material and design specifications, start-up
engine noises or knock may be experienced.
It is recommended you use the appropriate Motorcraft  oil filter or
another with equivalent performance for your engine application.
BATTERY
WARNING: This vehicle
may be equipped with more
than one battery, removal of cable
from only one battery does not
disconnect the vehicle electrical
system. Be sure to disconnect
cables from all batteries when
disconnecting power. Failure to do
so may cause serious personal
injury or property damage.
Your vehicle is equipped with a Motorcraft  maintenance-free battery
which normally does not require additional water during its life of
service.
If your battery has a cover/shield, make sure it is reinstalled
after the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals. Maintenance and Specifications

If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time. This will minimize the discharge of your battery
during storage.
Note: Electrical or electronic accessories or components added to
the vehicle by the dealer or the owner may adversely affect
battery performance and durability.
WARNING: Batteries normally produce explosive gases which
can cause personal injury. Therefore, do not allow flames, sparks
or lighted substances to come near the battery. When working near the
battery, always shield your face and protect your eyes. Always provide
proper ventilation.
WARNING: When lifting a plastic-cased battery, excessive
pressure on the end walls could cause acid to flow through the
vent caps, resulting in personal injury and/or damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.
WARNING: Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with skin or
eyes, flush immediately with water for a minimum of 15 minutes and
get prompt medical attention. If acid is swallowed, call a physician
immediately.
WARNING: Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands after handling.Maintenance and Specifications

Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift in P (Park), turn off all accessories and start the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
• The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.
• If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and radio settings must be reset once the battery is reconnected.
• Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
ENGINE COOLANT
Checking the engine coolant
Note: If your vehicle is equipped with a diesel engine, refer to the
Maintenance and Specifications section of your Diesel Supplement.
Check the concentration and level of the engine coolant at the intervals
listed in the Scheduled Maintenance Information.
The coolant concentration should be maintained at 50%.

Note: For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note: The engine coolant should be at the FULL COLD level, or between
the MIN and MAX marks, or within the COLD FILL RANGE, as listed on
the engine coolant reservoir (depending upon the application).
Note: Coolant expands when it is hot. The level may extend beyond the
FULL COLD level, or the MAX mark, or the COLD FILL RANGE.
If the level is below the FULL COLD level, at or below the MIN mark, or
below the COLD FILL RANGE, add coolant immediately per the Adding
engine coolant instructions in this chapter.
Note: Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
WARNING: Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING: Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
WARNING: To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
WARNING: Do not add coolant further than the MAX mark.
Note: Do not use stop leak pellets, cooling system sealants, or unapproved
additives as they can cause damage to the engine cooling or heating
systems. This damage would not be covered under your vehicle’s warranty.Maintenance and Specifications
