CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
Your vehicle may be equipped with a conventional spare tire that is
different in one or more of the following: type, brand, size, speed rating
and tread design. If this is the case, this dissimilar spare tire is still rated
for your vehicle loads (GAWR and GVWR).Temporary spare tires are not
equipped with Tire Pressure Monitor System (TPMS) sensors if the
system is present.
The use of tire sealant may damage your Tire Pressure
Monitoring System (if equipped) and should not be used.
If your vehicle is equipped with a Tire Pressure Monitoring
System, refer toTire Pressure Monitoring Systemin theTires,
Wheels and Loadingchapter for more information. If the tire pressure
monitor sensor becomes damaged, it will no longer function.

Note:Poor wiper quality can be improved by cleaning the wiper blades
and the windshield; refer toWindows and wiper bladesin the
Cleaningchapter.
Note:To prolong the life of the wiper blades, it is highly recommended
to scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.

6. Wipe the dipstick clean. Insert the dipstick 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 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 mark 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 or until the cap is fully seated.
To avoid possible oil loss, DO NOT operate the vehicle with the
engine oil 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.
