Changing rear window wiper blade
The rear wiper arm is designed without a service position. This reduces
the risk of damage to the blade in an automatic car wash.
To replace the wiper blade:
1. Grab the wiper arm with one
hand close to the arm/blade joint
and pull it as far away from the
glass as possible. Do not use
excessive force because it can break
the wiper arm at the heel. Hold it
there until the next step.
2. Grab the primary structure of the
blade with the other hand close to
the arm/blade joint.
3. Grip tightly and push on the arm/blade joint from beneath and
separate the blade from the arm.
4. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
If you find this procedure too
difficult, please see your dealer.
ENGINE OIL
Checking the engine oil
Refer toscheduled maintenance informationfor the appropriate
intervals for checking the engine oil.
1. Make sure the vehicle is on level ground.
2. Turn the engine off and wait 15 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 dipstick.

6. Wipe the dipstick clean. Insert the dipstick fully, then remove it again.
•If the oil level is within the lower and upper holes, or lower and upper
marks, the oil level is acceptable.DO NOT ADD OIL.
•If the oil level is below the lower hole or lower mark, engineoil must
be addedto raise the level within the normal operating range.

•If required, add engine oil to the engine. Refer toAdding engine oil
in this chapter.
•Do not overfill the engine with oil. Oil levels above the upper
hole or upper mark may cause engine damage.If the engine is
overfilled, some oil must be removed from the engine by an authorized
dealer.
7. Put the dipstick 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.
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, FULL or upper hole/mark (depending on application) 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
1/4 of a turn until it is seated.
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 and 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.Refer toMaintenance product specifications and
capacitieslater 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 thescheduled maintenance information.
Ford production and Motorcraft 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 oil filter or
another with equivalent performance for your engine application.

If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations 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 inscheduled maintenance information.The coolant
concentration should be maintained at 50/50 coolant and distilled water,
which equates to a freeze point of -34°F (-36°C). Coolant concentration
testing is possible with a hydrometer or antifreeze tester. 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 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 -34°F (-36°C).
•Boiling protection up to 265°F (129°C).
•Protection against rust and other forms of corrosion.
•Proper function of calibrated gauges.

•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 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.
