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.
2. If the engine oil level is not within the MIN and MAX ranges, 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 dipstick.
Engine oil and filter recommendations
Look for this certification mark.
Ford oil specification is WSS-M2C153-G.
Use SAE 5W-30 motor oil certified for gasoline engines by the American
Petroleum Institute.
Maintenance and care

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, startup
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.
BRAKE FLUID
Checking and adding brake fluid
Brake fluid should be checked and
refilled as needed. Refer to the
Scheduled Maintenance Guide for
the service interval schedules:
1. Clean the reservoir cap before
removal to prevent dirt or water
from entering the reservoir.
2. Visually inspect the fluid level.
3. If necessary, add brake fluid until
the level reaches MAX. Do not fill
above this line.
4. Use only a DOT 3 brake fluid
certified to meet Ford specifications.
Refer toLubricant specificationsin theCapacities and specifications
chapter.
Brake fluid is toxic.

²Use recommended engine oil. Refer toLubricant Specifications.
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
2 km/h [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollover/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²Use of 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 over hilly terrain.
²Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
²Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of Km/L (MPG) expected on
the vehicle, depending upon the driver's method of operation and
conditions.
EMISSION CONTROL SYSTEM
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
Maintenance and care

Washing your vehicle
Wash your vehicle regularly with
cold or lukewarm water. Never use
strong detergents or soap. If your
vehicle is particularly dirty, use a
quality car wash detergent. Always
use a clean sponge, washing glove
or similar device and plenty of water
for best results. To avoid spots,
avoid washing when the hood is still
warm, immediately after or during
exposure to strong sunlight.
During winter months, it is especially important to wash the vehicle on a
regular basis. Large quantities of dirt and road salt are difficult to
remove and also cause damage to the vehicle.
Remove any exterior accessories, such as antennas, before entering a car
wash. If you have wax applied to the vehicle at a commercial car wash, it
is recommended that you clean the wiper blades and windshield as
described inCleaning the wiper blades and windshield.
After washing, apply the brakes several times to dry them.
Waxing your vehicle
Wax when water stops beading on the surface. This could be every three
or four months, depending on operating conditions.
Use only carnauba or synthetic-based waxes. Use cleaning fluid or
alcohol with a clean cloth to remove any bugs and tar before waxing
vehicle. Use tar remover to remove any tar spots.
Avoid getting wax on the windshield. If you have wax applied at a
commercial car wash, it is recommended that you clean the wiper blades
and windshield as described inCleaning the wiper blades and
windshield.
Repairing paint chips
Minor scratches or paint damage from road debris may be repaired with
touch-up paint, repair foil or aerosol paint spray from the Ford Car Care
Chemicals line. Observe the application instructions on the products.
Remove particles such as bird droppings, tree sap, insect remains, tar
spots, road salt and industrial fallout immediately.
Maintenance and care
171

Cleaning the interior fabric
Remove dust and loose dirt with a whisk broom or a vacuum cleaner.
Remove fresh spots immediately. Do not use household or glass cleaners.
These agents can stain and discolor the fabric. Use a mild soap and
water solution if necessary.
Cleaning and maintaining the safety belts
Clean the safety belts with a mild soap solution recommended for
cleaning upholstery or carpets. Do not bleach or dye the belts, because
these actions may weaken the belt webbing.
Check the safety belt system periodically to make sure there are no
nicks, wear or cuts. If your vehicle has been involved in an accident,
refer to theSafety belt maintenancesection in theSeating and safety
restraintschapter.
Underbody
Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
Cleaning leather seats (if equipped)
To clean, simply use a soft cloth dampened with water and a mild soap.
Wipe the leather again with a damp cloth to remove soap residue. Dry
with a soft cloth. For tougher soiling concerns, Ford recommends using
the Deluxe Leather Care Kit F8AZ-19G253±AA, which is available from
your Ford Dealer. This mild cleaner and special pad, cleans the leather
and maintains its natural beauty. Follow the instructions 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 or plastics.
Inside windows
Use glass cleaner for the inside windows if they become fogged.
