CLEANING LEATHER SEATS (IF EQUIPPED)
All Ford, Lincoln and Mercury vehicles with leather seating surfaces have
a clear, protective coating over the leather.
To clean the leather seats, simply use a soft cloth with Deluxe Leather
and Vinyl Cleaner (F2AZ-19521±WA). Dry the area with a soft cloth.
It is recommended that you use the Deluxe Leather Care Kit
(F8AZ-19G253±AA), available from your authorized Ford, Lincoln or
Mercury dealer. The mild cleaner and special pad available in the kit
cleans the leather and maintains its natural beauty. For best results,
follow the instructions printed on the cleaner label. Regular cleaning of
your leather upholstery helps maintain its resiliency and color.
Do not use household cleaning products, alcohol solutions,
solvents or cleaners intended for rubber, vinyl and plastics, or
oil/petroleum-based leather conditioners. These products may
cause premature wearing of the clear, protective coating.
CLEANING THE INSIDE WINDOWS
Use Ultra Clear Spray Glass Cleaner (E4AZ-19C507±AA) for the inside
windows if they become fogged.
To clean, use two lint-free, soft towels, folded into a pad-shape. Mist the
glass completely with cleaner, and use one of the towels to evenly agitate
the surface. Use the other towel to remove the residue.
CLEANING AND MAINTAINING THE SAFETY BELTS
Clean the safety belts with Extra Strength Upholstery Cleaner
(E8AZ-19523±AA), available from your authorized Ford, Lincoln or
Mercury dealer.
Do not use bleach, dye or any other solvent to clean the belts, as
these actions may weaken the belt webbing.
UNDERBODY
Flush the complete underside of your vehicle frequently. Keep body and
door drain holes free from packed dirt.

²Do not overfill the engine
with oil. Oil levels above this
mark may cause engine
damage.If the engine is
overfilled, some oil must be removed from the engine by a qualified
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.
2.
If the engine oil level is not within the normal operating 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
normal operating range 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
until three clicks can be heard.
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 OVERFILL
Maintenance and Specifications
199

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.
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.

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.
²
You 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.
Conditions
²Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
²Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²Using fuel blended with alcohol may lower fuel economy.
²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
