seated.
Adding engine oil
1. Check the engine oil. For instructions, refer to
Checking the engine oilin this chapter.
2. If the engine oil level is not within the normal
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 MAX mark on the engine oil
level indicator (dipstick).

4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the
filler cap clockwise 1/4 of a turn until three clicks
are heard or until the cap is fully seated.
To avoid possible oil loss, DO NOT operate the
vehicle with the engine oil level indicator
and/or the engine oil filler cap removed.
Engine oil and filter recommendations
Look for this
certification trademark.
SAE 5W-20 engine oil is recommended.
Only use oils ªCertified For Gasoline Enginesº by the
American Petroleum Institute (API). Use Motorcraft
or an equivalent oil meeting Ford specification
WSS-M2C153±H.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, oil
treatments or engine treatments. They are
unnecessary and could, under certain conditions,
lead to engine damage which is not covered by your
warranty.
Change your engine oil and filter according to the
appropriate schedule listed in the scheduled
maintenance guide.
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.
Maintenance and Specifications
209

It is recommended you use the appropriate
Motorcraft oil filter (or another brand meeting Ford
specifications) 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.
However, for severe usage or in high temperature
climates, check the battery electrolyte level. Refer to
the scheduled maintenance guide for the service
interval schedules.
Keep the electrolyte level in each cell up to the
ªlevel indicatorº. Do not overfill the battery
cells.
If the electrolyte level in the battery is low, you can
add plain tap water to the battery, as long as you do
not use hard water (water with a high mineral or
alkali content). If possible, however, try to only fill
the battery cells with distilled water. If the battery
needs water often, have the charging system
checked.
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.

²Always 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 mileage intervals in the scheduled
maintenance guide. The coolant concentration
should be maintained at 50/50 coolant and water,
which equates to a freeze point of -36É C (-34É F).
Coolant concentration testing is possible with a
hydrometer or antifreeze tester (such as the
Rotunda Battery and Antifreeze Tester, 014±R1060).
The level of coolant should be maintained at the
ªcold fullº of ªcold fill rangeº level in the coolant
reservoir. If the level falls below, add coolant per the
instructions in theAdding Engine Coolantsection.
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:
²freeze protection down to -36É C (-34É F)
²boiling protection up to 129É C (265É F)
²protection against rust and other forms of
corrosion
²enables calibrated gages to function properly

²Anticipate stopping; slowing down may eliminate
the need to stop.
²Sudden or hard accelerations may reduce fuel
economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h
[55 mph] uses 15% less fuel than traveling at
105 km/h [65 mph]).
²Revving the engine before turning it off may
reduce fuel economy.
²Using the air conditioner or defroster may reduce
fuel economy.
²You may want to turn off the speed control in
hilly terrain if unnecessary shifting between third
and fourth gear occurs. Unnecessary shifting of
this type could result in reduced fuel economy.
²Warming up a vehicle on cold mornings is not
required and may reduce fuel economy.
²Resting your foot on the brake pedal while driving
may reduce fuel economy.
²Combine errands and minimize stop-and-go
driving.
Maintenance
²Keep tires properly inflated and use only
recommended size.
²Operating a vehicle with the wheels out of
alignment will reduce fuel economy.
²Use recommended engine oil. Refer toLubricant
specificationsin this chapter.
²Perform all regularly scheduled maintenance
items. Follow the recommended maintenance
schedule and owner maintenance checks found in
your vehicle scheduled maintenance guide.
Maintenance and Specifications

²Drive cautiously. If you hear the chains rub or
bang against your vehicle, stop and re-tighten the
chains. If this does not work, remove the chains
to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer
needed. Do not use tire chains on dry roads.
²The suspension insulation and bumpers will help
prevent vehicle damage. Do not remove these
components from your vehicle when using snow
tires and chains.
