Engine oil and filter recommendations

Look for this certification
trademark.

Use SAE 5W-20 engine oil

Only use oils certified for gasoline engines by the American Petroleum
Institute (API). An oil with this trademark symbol conforms to the
current engine and emission system protection standards and fuel
economy requirements of the International Lubricant Standardization and
Approval Committee (ILSAC), comprised of U.S. and Japanese
automobile manufacturers.

To protect your engine and engine’s warranty, use Motorcraft

威 SAE

5W-20 or an equivalent SAE 5W-20 oil meeting Ford specification
WSS-M2C930-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

威 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

威 oil filter or

another with equivalent performance for your engine application.

BATTERY

Your vehicle is equipped with a
Motorcraft

威 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.

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.

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. Flexible fuel vehicles (FFV) must also relearn the ethanol
content of the fuel 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. Release the parking brake. With your foot on the brake pedal and with
the A/C on, put the vehicle in D (Drive) and allow the engine to idle for
at least one minute.

7. 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 along with the ethanol content
for flexible fuel vehicles.

• 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.

• For flexible fuel vehicles, if you are operating on E85, you may

experience poor starts or an inability to start the engine and
driveability problems until the fuel trim and ethanol content have been
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 engine coolant

The concentration and level of engine coolant should be checked at the
intervals listed in scheduled maintenance information. The coolant
concentration should be maintained at 50/50 coolant and distilled water.
For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300- ROB75240E available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentration. The level of coolant should
be maintained at the FULL COLD level or within the COLD FILL RANGE
in the coolant reservoir. If the level falls below, add coolant per the
instructions in the Adding engine coolant section.

Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly. A
50/50 mixture of coolant and water provides the following:
• Improved freeze protection.
• Improved boiling protection.
• Protection against rust and other forms of corrosion.
• Proper function of calibrated gauges.
