Adding Engine Coolant
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.
Note:Do not use stop leak pellets, cooling system sealants or additives,
as they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
Note:During normal vehicle operation, the engine coolant may change
color from orange to pink or light red. As long as the engine coolant is
clear and uncontaminated, this color change does not indicate the engine
coolant has degraded nor does it require the engine coolant to be
drained, the system to be flushed, or the engine coolant to be replaced.
•DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. Mixing of engine coolants may harm
your engine’s cooling system. The use of an improper coolant may
harm engine and cooling system components and may void the
warranty.
•In case of emergency, a large amount of water without engine coolant
may be added in order to reach a vehicle service location. In this
instance, the cooling system must be drained, chemically cleaned with
Motorcraft Premium Cooling System Flush, and refilled with engine
coolant as soon as possible. Water alone (without engine coolant) can
cause engine damage from corrosion, overheating or freezing.

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 system. There is
no fluid reservoir to check or fill.
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.
CHANGING THE VEHICLE BATTERY
WARNING:Batteries normally produce explosive gases which
can cause personal injury. Therefore, do not allow flames, sparks
or lighted substances to come near the battery. When working near the
battery, always shield your face and protect your eyes. Always provide
proper ventilation.
WARNING:When lifting a plastic-cased battery, excessive
pressure on the end walls could cause acid to flow through the
vent caps, resulting in personal injury and damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.
WARNING:Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with skin or
eyes, flush immediately with water for a minimum of 15 minutes and
get prompt medical attention. If acid is swallowed, call a physician
immediately.
WARNING:Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands after handling.
Your vehicle is equipped with a Motorcraft® maintenance-free battery
which normally does not require additional water during its life of
service.
Note:If your battery has a cover or a 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.

CHECKING THE WIPER BLADES
Run the tip of your fingers over the edge of the blade
to check for roughness.
Clean the wiper blades with washer fluid or water
applied with a soft sponge or cloth.
CHANGING THE WIPER BLADES
1. Pull the wiper arm away from the
vehicle. Turn the blade at an angle
from the wiper arm. Press the lock
tab to release the blade and pull the
wiper blade down toward the
windshield to remove it from the arm.
2. Attach the new wiper to the wiper
arm and press it into place until a
click is heard.
Replace wiper blades at least once per year for optimum performance.
Poor wiper quality can be improved by cleaning the wiper blades and the
windshield.
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.
Changing rear window wiper blade
To replace the rear wiper blade:
1. Grab the wiper arm with one
hand close to the arm/blade joint
and pull it as far away from the
glass as possible. Do not use
excessive force because it can break
the wiper arm at the heel. Hold it
there until the next step.
2. Grab the primary structure of the blade with the other hand close to
the arm/blade joint.

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.
•Never use strong household detergents or soap, such as dish washing
or laundry liquid. These products can discolor and spot painted
surfaces.
•Never wash a vehicle that is hot to the touch or during exposure to
strong, direct sunlight.

WAXING
Regular waxing is necessary to protect your car’s paint from the
elements. We recommend that you wash and wax the painted surface
once or twice a year.
When washing and waxing, park your vehicle in a shaded area out of
direct sunlight. Always wash your vehicle before applying wax.
•Use a quality wax that does not contain abrasives.
•Follow the manufacturer’s instructions to apply and remove the wax.
•Apply a small amount of wax in a back-and-forth motion, not in
circles.
•Do not allow wax to come in contact with any non-body (low-gloss
black) colored trim. The wax will discolor or stain the parts over
time, such as:
•Bumpers
•Grained door handles
•Side mouldings
•Mirror housings
•Windshield cowl area.
•Do not apply wax to glass areas.
•After waxing, your car’s paint should feel smooth, and be free of
streaks and smudges.
REPAIRING MINOR PAINT DAMAGE
Your authorized dealer has touch-up paint to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jamb) to
your authorized dealer to make sure you get the correct color.
•Remove particles, such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout, before repairing paint chips.
•Always read the instructions before using the products.
CLEANING THE ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal.
When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
Vehicle Care317

•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.
•The wiper blades can be cleaned with isopropyl (rubbing) alcohol or
Motorcraft Premium Windshield Washer Concentrate with Bitterant
in the U.S., or Premium Quality Windshield Washer Fluid in Canada.
Be sure to replace wiper blades when they appear worn or do not
function properly.
•Do not use abrasives, 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.
