2. If the engine oil level is not within the normal operating range, add
only certified engine oil of the recommended viscosity. Remove the
engine oil filler cap and use a funnel to pour the engine oil into the
opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level dipstick.
4. Install the dipstick and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks can be heard.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil level dipstick and/or the engine oil filler cap removed.
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’s warranty, use Motorcraft 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.
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 thescheduled maintenance information.

Ford production and aftermarket (Motorcraft) 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
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.
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.

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:
•Freeze protection down to -34°F (-36°C).
•Boiling protection up to 265°F (129°C)
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the “FULL COLD” level or within the
“COLD FILL RANGE” as listed on the engine coolant reservoir
(depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin 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.

•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
1 mpg [0.4 km/L] is lost for every 400 lb [180 kg] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Close windows for high speed driving.
EPA fuel economy estimates
Every new vehicle should have a window sticker containing EPA fuel
economy estimates. Contact your authorized dealer if the window sticker
is not supplied with your vehicle. The EPA fuel economy estimates
should be your guide for the fuel economy comparisons with other
vehicles. Your fuel economy may vary depending upon the method of
operation and conditions.
