UTILIZING THE MEDIATION or ARBITRATION PROGRAM
(CANADA ONLY)
This pertains to vehicles delivered to authorized Canadian dealers. In
those cases, where you continue to feel that the efforts by Ford of
Canada and the authorized dealer to resolve a factory-related vehicle
service concern have been unsatisfactory, Ford of Canada participates in
an impartial third party mediation or arbitration program administered by
the Canadian Motor Vehicle Arbitration Plan (CAMVAP).
The CAMVAP program is a straightforward and relatively speedy
alternative to resolve a disagreement when all other efforts to produce a
settlement have failed. This procedure is without cost to you and is
designed to eliminate the need for lengthy and expensive legal
proceedings.
In the CAMVAP program, impartial third-party arbitrators conduct
hearings at mutually convenient times and places in an informal
environment. These impartial arbitrators review the positions of the
parties, make decisions and, when appropriate, render awards to resolve
disputes. CAMVAP decisions are fast, fair, and final as the arbitrator’s
award is binding on both you and Ford of Canada.
CAMVAP services are available in all Canadian territories and provinces.
For more information, without charge or obligation, call your CAMVAP
Provincial Administrator directly at 1-800-207-0685 or visit
www.camvap.ca.
GETTING ASSISTANCE OUTSIDE THE U.S. AND CANADA
Before exporting your vehicle to a foreign country, contact the
appropriate foreign embassy or consulate. These officials can inform you
of local vehicle registration regulations and where to find unleaded fuel.
If you cannot find unleaded fuel or can only get fuel with an anti-knock
index lower than is recommended for your vehicle, contact our Customer
Relationship Center.
The use of leaded fuel in your vehicle without proper conversion may
damage the effectiveness of your emission control system and may cause
engine knocking or serious engine damage. Ford Motor Company or Ford
of Canada is not responsible for any damage caused by use of improper
fuel. Using leaded fuel may also result in difficulty importing your vehicle
back into the United States.

Adding Engine Oil
Note:Do not remove the filler cap when the engine is running.
Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
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 Lubricants
Specification Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Remove the filler cap.
2. Add engine oil that meets Ford specifications. SeeCapacities and
Specificationsfor more information.
3. Wipe off any spilled oil.
4. Replace the filler cap. Turn it until you feel a strong resistance.
ENGINE COOLANT CHECK
Checking the Engine Coolant
The concentration and level of engine coolant should be checked at the
intervals listed inScheduled Maintenance Information.
Note:Make sure that the level is between the MIN and MAX marks on
the coolant reservoir.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark.
If the level is at the MIN mark, below the MIN mark, or empty, add
coolant immediately. SeeAdding Engine Coolantin this chapter.
The coolant concentration should be maintained within 48% to 50%, which
equates to a freeze point between -30°F (-34°C) and -34°F (-37°C).
Note:For best results, coolant concentration should be tested with a
refractometer such as Robinair Coolant and Battery Refractometer
75240. We do not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.

4. Seat the air filter assembly back into the grommets by pushing down
on the air filter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that attach air filter assembly to the front
of the vehicle.
7. Install the bolt cover (if equipped).
8. Reinstall the harness retaining clip into the front of the air filter assembly.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAX lines are within the normal
operating range; there is no need to add fluid. If the fluid levels are outside
of the normal operating range, the performance of the system could be
compromised; seek service from your authorized dealer immediately.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric power steering (EPS) system.
There is no fluid reservoir to check or fill. For additional information on
the electric power steering (EPS) system, Refer toDriving Aids.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter that is integrated with
the fuel tank. Regular maintenance or replacement is not needed.
WASHER FLUID CHECK
WARNING:If you operate your vehicle in temperatures below 40°F
(5°C), use washer fluid with antifreeze protection. Failure to use
washer fluid with antifreeze protection in cold weather could result in
impaired windshield vision and increase the risk of injury or accident.
Add fluid to fill the reservoir if the level is low. Only use a washer fluid
that meets Ford specifications. See the technical specifications chart in
theCapacities and Specificationschapter.
Note:The front and rear washer systems are supplied from the same
reservoir.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.

Battery relearn
Because your vehicle’s engine is electronically controlled by a computer,
some control conditions are maintained by power from the battery. When
the battery is disconnected or a new battery is installed, the engine must
relearn its idle and fuel trim strategy for optimum driveability and
performance. To begin this process:
1. With the vehicle at a complete stop, set the parking brake.
2. Put the gearshift lever inP(Park), turn off all accessories and start
the engine.
3. Run the engine until it reaches normal operating temperature.
4. Allow the engine to idle for at least one minute.
5. Turn the A/C on and allow the engine to idle for at least one minute.
6. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven to relearn the idle and fuel trim
strategy.
•Note:If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle trim is
eventually relearned.
When the battery is disconnected or a new battery installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. This operation is considered normal and
will not affect function or durability of the transmission. Over time the
adaptive learning process will fully update transmission operation to its
optimum shift feel.
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.

•Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to the vehicle’s
paintwork and trim over time. Use Motorcraft Bug and Tar Remover.
•Note:Suntan lotions and insect repellents can damage any painted
surface; if these substances come in contact with your vehicle, wash it
off as soon as possible.
•Remove any exterior accessories before entering a car wash.
Stripes or Graphics (if equipped)
Do not use a commercial or high-pressure wand on the surface or edge
of stripes and graphics. This can cause damage to the film and cause the
edge of the film to peel away from the vehicle surface.
Exterior Chrome
Note:Never use abrasive materials such as steel wool or plastic pads as
they can scratch the chrome surface.
Note:Do not use chrome cleaner, metal cleaner or polish on wheels and
wheel covers.
•Wash the vehicle first, using cool or lukewarm water and a neutral pH
shampoo, such as Motorcraft Detail Wash.
•Use Motorcraft Custom Bright Metal Cleaner. Apply the product as
you would a wax to clean bumpers and other chrome parts; allow the
cleaner to dry for a few minutes, then wipe off the haze with a clean,
dry rag.
•Do not apply cleaning product to hot surfaces and do not leave
cleaning product on chrome surfaces for a period of time exceeding
that which is recommended.
•Note:Using other non-recommended cleaners can result in severe
and permanent cosmetic damage.
Underbody
Flush the complete underside of your vehicle frequently. Keep body and
door drain holes free from packed dirt.
Cleaning Plastic Exterior Parts
Use only approved products to clean plastic parts.
•For routine cleaning, use Motorcraft Detail Wash.
•If tar or grease spots are present, use Motorcraft Bug and Tar
Remover.

•Spray Motorcraft Engine Shampoo and Degreaser on all parts that
require cleaning and pressure rinse clean. In Canada, use Motorcraft
Engine Shampoo.
•Never wash or rinse the engine while it is hot or running; water in the
running engine may cause internal damage.
•Never wash or rinse any ignition coil, spark plug wire or spark plug
well, or the area in and around these locations.
•Cover the battery, power distribution box, and air filter assembly to
prevent water damage when cleaning the engine.
CLEANING THE WINDOWS AND WIPER BLADES
The windows and wiper blades should be cleaned regularly. If the wipers
do not wipe properly, substances on the vehicle’s glass or the wiper
blades may cause squeaking or chatter noise from the blades, and
streaking and smearing of the windshield. To clean these items, follow
these tips:
•The windows may be cleaned with a non-abrasive cleaner such as
Motorcraft® Ultra-Clear Spray Glass Cleaner (U.S.) or Motorcraft
Premium Glass Cleaner (Canada).
•The wiper blades can be cleaned with isopropyl (rubbing) alcohol or
Motorcraft Premium Windshield Washer Concentrates in the U.S., or
Motorcraft Premium Quality Windshield Washer Fluid in Canada.
Replace your wiper blades when they appear worn or do not function
properly.
•Do not use abrasive materials, as they may cause scratches.
•Do not use fuel, kerosene, or paint thinner to clean any parts.
If you cannot remove those streaks after cleaning with the glass cleaner
or if the wipers chatter and move in a jerky motion, clean the outer
surface of the windshield and the wiper blades using a sponge or soft
cloth with a neutral detergent or mild-abrasive cleaning solution. After
cleaning, rinse the windshield and wiper blades with clean water. The
windshield is clean if beads do not form when you rinse the windshield
with water.
Note:Do not use sharp objects, such as a razor blade, to clean the
inside of the rear window or to remove decals, as it may cause damage
to the rear window defroster’s heated grid lines.
