ENGINE OIL DIPSTICK

MAXB
ENGINE OIL CHECK
Check the level before starting the engineand make sure that the level is betweenthe MIN and the MAX marks.
1. Make sure that your vehicle is on levelground.
2. Switch the engine off and wait 10minutes for the oil to drain into the oilpan.
3. Remove the dipstick and wipe it witha clean, lint-free cloth. Replace thedipstick and remove it again to checkthe oil level.
If the oil level is at the minimum mark, addoil immediately.
Adding Engine Oil
Note:Do not remove the filler cap whenthe engine is running.
Note:Do not add oil further than the MAXmark. Oil levels above the MAX mark maycause engine damage.
Only use oils certified for gasoline enginesby the American Petroleum Institute (API).An oil with this trademark symbolconforms to the current engine andemission system protection standards andfuel economy requirements of theInternational Lubricants SpecificationAdvisory Council (ILSAC), comprised ofU.S. and Japanese automobilemanufacturers.
1. Remove the filler cap.
2. Add engine oil that meets the Fordspecifications. See Capacities andSpecifications (page 282).
3. Wipe off any spilled oil.
4. Replace the filler cap. Turn it until youfeel a strong resistance.

Low Engine Use (If Equipped)
The low engine use mode is equipped onEnergi models only. The low engine usemode keeps the engine oil quality in goodcondition when you drive your vehicle withlimited engine use. If your vehicle is in lowengine use mode when you start thevehicle, a message appears in theinformation display. When your vehicle isin low engine use mode, your vehicle runsthe engine as necessary.
Selecting EV Now mode when your vehicleis in the low engine use mode suspendsthe low engine use mode for as long as youcontinue driving your vehicle. The lowengine use mode resumes the next timeyou start your vehicle.
Changing the engine oil and resetting theoil life monitoring system suspends the lowengine use mode.
Operating in Cold Climates andShort Driving Cycles
Some gasoline engines may experience abuildup of moisture in the engine oil ifrepeatedly operated in cold weather andshort driving cycles that do not fully warmthe engine.
When you see a thick milky substanceunder the oil cap, this indicates moistureis present.
This condition can be more prevalent ingas electric hybrid vehicles that run the gasengine for very short driving cycles.
To prevent engine damage under theseconditions customers should follow thesesteps:
•Drive your vehicle at full enginetemperature for 15 to 30 minutes.
•Drive your vehicle at highway speeds.
•Drive your vehicle with the defroster(hybrid vehicles) at full.
We recommend frequent oil changes.Follow severe duty cycle in themaintenance guide. This helps remove themoisture contaminated oil from the engine.
Cold Weather Operation
To determine if the shortened oil changeinterval or warming of the engine issufficient, clean and check the oil fill capon a regular basis. This will confirm thatthe thick milky substance is not returning.
When extreme cold weather and sub-zeroconditions exist, fuel may be found in theengine oil. This is caused by the engine notreaching its full engine temperature.
In this situation, carry out the above stepsto prevent engine damage.
OIL CHANGE INDICATOR
RESET (If Equipped)
Resetting the Oil Life MonitoringSystem
Only reset the oil life monitoring systemafter changing the engine oil and oil filter.
1.Switch the ignition on. Do not start theengine. For vehicles with push-buttonstart, press and hold the start buttonfor two seconds without pressing thebrake pedal. Do not start the engine.
2.Press the accelerator and brake pedalsat the same time.
3.Keep the accelerator and brake pedalsfully pressed.
4. After three seconds, a messageconfirming that the reset is in progresswill be displayed.
5. After 25 seconds, a messageconfirming that the reset is completewill be displayed.
6. Release the accelerator and brakepedals.

Maintenance
•Do not allow wax to come in contactwith any non-body (low-gloss black)colored trim. The wax will discolor orstain the parts over time.
•Roof racks.
•Bumpers.
•Grained door handles.
•Side moldings.
•Mirror housings.
•Windshield cowl area.
•Do not apply wax to glass areas.
•After waxing, your car's paint shouldfeel smooth, and be free of streaks andsmudges.
CLEANING THE ENGINE
Engines are more efficient when they areclean because grease and dirt buildup keepthe engine warmer than normal.
When washing:
•Take care when using a power washerto clean the engine. The high-pressurefluid could penetrate the sealed partsand cause damage.
•Do not spray a hot engine with coldwater to avoid cracking the engineblock or other engine components.
•Spray Motorcraft Engine Shampoo andDegreaser on all parts that requirecleaning and pressure rinse clean. InCanada, use Motorcraft EngineShampoo.
•Never wash or rinse the engine while itis hot or running; water in the runningengine may cause internal damage.
•Never wash or rinse any ignition coil,spark plug wire or spark plug well, orthe area in and around these locations.
•Cover the battery, power distributionbox, and air filter assembly to preventwater damage when cleaning theengine.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmentalfallout can result in windshield and wiperblade contamination. Dirty windshield andwipers will result in poor windshield wiperoperation. Keep the windshield and wiperblades clean to maintain windshield wiperperformance.
To clean the windshield and wiper blades:
•Clean the windshield with anon-abrasive glass cleaner. Whencleaning the interior of the windshield,avoid getting any glass cleaner on theinstrument panel or door panels. Wipeany glass cleaner off these surfacesimmediately.
•For windshields contaminated withtree sap, chemicals, wax or bugs, cleanthe entire windshield using steel wool(no greater than 0000 grade) in acircular motion and rinse with water.
•Clean the wiper blades with isopropylrubbing alcohol or windshield washerconcentrate.
Note: Do not use razor blades or othersharp objects to clean or remove decalsfrom the inside of the heated rear window.The vehicle warranty does not coverdamage caused to the heated rear windowgrid lines.

Vehicle Care
Alloy wheels and wheel covers are coatedwith a clear coat paint finish. To maintaintheir condition we recommend that you:
•Clean them weekly with therecommended wheel and tire cleaner.
•Use a sponge to remove heavydeposits of dirt and brake dustaccumulation.
•Rinse them thoroughly with apressurized stream of water when youhave completed the cleaning process.
We recommend that you use Ford servicewheel cleaner. Make sure that you readand follow the manufacturer’s instructions.
Using other non-recommended cleaningproducts can result in severe andpermanent cosmetic damage.
VEHICLE STORAGE
If you plan on storing your vehicle for 30days or more, read the followingmaintenance recommendations to makesure your vehicle stays in good operatingcondition.
We engineer and test all motor vehiclesand their components for reliable, regulardriving. Under various conditions,long-term storage may lead to degradedengine performance or failure unless youuse specific precautions to preserve enginecomponents.
General
•Store all vehicles in a dry, ventilatedplace.
•Protect from sunlight, if possible.
•If you store vehicles outside, theyrequire regular maintenance to protectagainst rust and damage.
Body
•Wash your vehicle thoroughly toremove dirt, grease, oil, tar or mud fromexterior surfaces, rear-wheel housingand the underside of front fenders.
•Periodically wash your vehicle if youstore it in exposed locations.
•Touch-up exposed or primed metal toprevent rust.
•Cover chrome and stainless steel partswith a thick coat of auto wax to preventdiscoloration. Re-wax as necessarywhen you wash your vehicle.
•Lubricate all hood, door and luggagecompartment hinges and latches witha light grade oil.
•Cover interior trim to prevent fading.
•Keep all rubber parts free from oil andsolvents.
Engine
•Change the engine oil and filter prior tostorage because used engine oilcontains contaminates which maycause engine damage.
•Start the engine every 15 days for aminimum of 15 minutes. Run at fast idlewith the climate controls set to defrostuntil the engine reaches normaloperating temperature.
•With your foot on the brake, shiftthrough all the gears while the engineis running.
•We recommend that you change theengine oil before you use your vehicleagain.
Fuel System
•Fill the fuel tank with high-quality fueluntil the first automatic shutoff of thefuel pump nozzle.
