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 Lubricants Specification
Advisory Committee (ILSAC), comprised
of U.S. and Japanese automobile
manufacturers.
To top up the engine oil level do the
following:
Clean the area surrounding the engine oil
filler cap before you remove it.
1. Remove the engine oil filler cap. See
Under Hood Overview (page 87).
Turn it counterclockwise and remove
it.
2. Add engine oil that meets the correct specification. See
Capacities and
Specifications (page 129). You may
have to use a funnel to pour the engine
oil into the opening.
3. Recheck the oil level.
4. If the oil level is correct, replace the dipstick and make sure it is fully seated.
5. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Make sure you install the oil filler cap
correctly.
Note: Soak up any spillage with an
absorbent cloth immediately. OIL CHANGE INDICATOR
RESET
Resetting the Oil Life Monitoring
System
Only reset the oil life monitoring system
after changing the engine oil and oil filter.
To reset the oil life monitoring system do
the following:
1.
Switch the ignition on. Do not start the
engine.
2. Fully press the accelerator and brake pedals at the same time.
3. Keep the accelerator and brake pedals
fully pressed.
4. After three seconds, a message displays confirming the reset procedure
is in progress.
5. After 25 seconds, a message displays confirming the reset procedure is
complete.
6. Release the accelerator and brake pedals.
7. Switch the ignition off.
ENGINE COOLANT CHECK WARNINGS
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, spilling
coolant on hot engine parts can burn you. 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.

Underbody
Flush the complete underside of your
vehicle frequently. Keep body and door
drain holes free of debris or foreign
material.
Under Hood
For removing black rubber marks from
under the hood we recommend Motorcraft
Wheel and Tire Cleaner or Motorcraft Bug
and Tar Remover.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
When washing:
•
Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold
water to avoid cracking the engine
block or other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine
Shampoo.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine. CLEANING THE ALLOY
WHEELS (If Equipped)
Note: Do not apply a cleaning chemical to
warm or hot wheel rims and covers.
Note: Some automatic car washes may
cause damage to the finish on your wheel
rims and covers.
Note: Industrial-strength or heavy-duty
cleaners in combination with brush agitation
to remove brake dust and dirt, could wear
away the clear coat finish over a period time.
Note: Do not use hydrofluoric acid-based
or high caustic-based wheel cleaners, steel
wool, fuels or strong household detergents.
Note: If you intend parking your vehicle for
an extended period after cleaning the
wheels with a wheel cleaner, drive your
vehicle for a few minutes before doing so.
This will reduce the risk of increased
corrosion of the brake discs.
Alloy wheels and wheel covers are coated
with a clear coat paint finish. To maintain
their condition we recommend that you:
• Clean the wheels weekly using
Motorcraft Wheel and Tire Cleaner.
Apply using manufacturer's
instructions.
• Use a sponge to remove heavy
deposits of dirt and brake dust
accumulation.
• Rinse thoroughly with a strong stream
of water when you have completed the
cleaning process.
• To remove tar and grease, use
Motorcraft Bug and Tar Remover.
