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 specification WSB-M8B16–A2.
Refer toLubricant specifications
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.
If you operate your vehicle in temperatures below 4.5°C (40°
F), 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.
Note:Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling system
components.
ENGINE OIL
Checking the engine oil
Refer to the scheduled maintenance guide for the appropriate intervals
for checking the engine oil.
1. Make sure the vehicle is on level ground.
Maintenance and Specifications
156

2. Turn the engine off and wait a few minutes for the oil to drain into the
oil pan.
3. Set the parking brake and ensure the gearshift is securely latched in P
(Park).
4. Open the hood. Protect yourself from engine heat.
5. Locate and carefully remove the
engine oil level indicator (dipstick).
6. Wipe the indicator clean. Insert the indicator fully, then remove it
again.
•If the oil level isbetween the MIN and MAX marks,the oil level is
acceptable.DO NOT ADD OIL.
•If the oil level is below the MIN
mark, add enough oil to raise the
level within the MIN-MAX range.
•Oil levels above the MAX mark may cause engine damage. Some oil
must be removed from the engine by a service technician.
7. Put the indicator back in and ensure it is fully seated.
Adding engine oil
1. Check the engine oil. For instructions, refer toChecking the engine
oilin this chapter.
Maintenance and Specifications
157

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
tightly until clicks are heard, or until it is snug.
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“Certified For Gasoline Engines”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.
It is recommended you use the appropriate Motorcraft oil filter (or
another brand meeting Ford specifications) for your engine application.

•Alwaysdisposeofautomotive
batteriesin 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 listed in the scheduled maintenance guide. The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -36°C (-34°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“cold full”of“cold fill range”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:
•Freeze protection down to -36°C (-34°F).
•Boiling protection up to 129°C (265°F).
•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.

Habits
•Smooth, moderate operation can yield up to 10% savings in fuel.
•Steady speeds without stopping will usually give the best fuel
economy.
•Idling for long periods of time (greater than one minute) may waste
fuel.
•Anticipate stopping; slowing down may eliminate the need to stop.
•Sudden or hard accelerations may reduce fuel economy.
•Slow down gradually.
•Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between fourth and fifth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•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 toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
