ENGINE OIL CHECK
1. Make sure that your vehicle is on level ground.
2. Check the oil level before starting the engine, or switch the engine off and
wait 15 minutes for the oil to drain into
the oil pan.
3. Remove the dipstick and wipe it with a clean, lint free cloth. Replace the
dipstick and remove it again to check
the oil level. If the oil level is at the minimum mark, add
oil immediately. See Capacities and
Specifications (page 265).
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by your vehicle warranty.
Note: Make sure that the oil level is
between the minimum and the maximum
marks.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
.
Adding 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 Lubricants Specification
Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile
manufacturers.
WARNINGS
Only add oil when the engine is cold.
If the engine is hot, wait 10 minutes
for the engine to cool down.
Do not remove the filler cap when
the engine is running.

1. Remove the engine oil filler cap.
2. Add engine oil that meets Ford
specifications. See Capacities and
Specifications (page 265).
3. Wipe off any spilled oil.
4. Replace the engine oil filler cap. Turn it clockwise until you feel a strong
resistance.
Note: Do not add oil further than the
maximum mark. Oil levels above the
maximum mark may cause engine damage.
Note: Soak up any spillage with an
absorbent cloth immediately.
ENGINE COOLANT CHECK
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information. See
Scheduled Maintenance
(page 336).
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.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add coolant
immediately. See
Adding Engine Coolant
in this chapter.
Maintain coolant concentration 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, for example 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.
Adding Engine Coolant WARNINGS
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, spilling
coolant on hot engine parts can burn you. Do not put engine coolant in the
windshield washer fluid reservoir. If
sprayed on the windshield, engine
coolant could make it difficult to see
through the windshield. Do not add coolant further than the
MAX mark.
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. Note:
Do not use stop leak pellets, cooling
system sealants or additives as they can
cause damage to the engine cooling or
heating systems. The vehicle warranty does
not cover this damage.
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 that the
engine coolant has degraded, nor does it
require that qualified personnel drain the
engine coolant, flush the system or replace
the engine coolant.

•
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 the engine ’s
cooling system. The use of incorrect
coolant may harm engine and cooling
system components and may void the
warranty. Use prediluted engine
coolant meeting the Ford specification.
See Capacities and Specifications
(page 265).
• In case of emergency, you can add a
large amount of water without engine
coolant in order to reach a vehicle
service location. In this instance, you
must have the cooling system 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, for
example corrosion, overheating or
freezing.
• Do not use alcohol, methanol, brine or
any engine coolants mixed with alcohol
or methanol antifreeze. Alcohol and
other liquids can cause engine damage,
for example overheating or freezing.
• Do not add extra inhibitors or additives
to the coolant. These can be harmful
and compromise the corrosion
protection of the engine coolant.
Unscrew the cap slowly. Any pressure will
escape as you unscrew the cap.
Add prediluted engine coolant meeting the
Ford specification. See
Capacities and
Specifications (page 265).
Whenever you add coolant, check the
coolant level in the coolant reservoir the
next few times you drive the vehicle. If
necessary, add enough prediluted engine
coolant to bring the coolant level to the
correct level. Recycled Engine Coolant
We do not recommend the use of recycled
engine coolant since a Ford-approved
recycling process is not yet available.
Used engine coolant should be disposed
of in an appropriate manner. Follow your
community
’s regulations and standards
for recycling and disposing of automotive
fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to have a Ford
authorized dealer increase the coolant
concentration above 50%.
• A coolant concentration of 60% will
provide improved freeze point
protection. Engine coolant
concentrations above 60% will
decrease the overheat protection
characteristics of the engine coolant
and may cause engine damage.
If you drive in extremely hot climates:
• It may be necessary to have a Ford
authorized dealer decrease the coolant
concentration to 40%.
• A coolant concentration of 40%
provides improved overheat protection.
Engine coolant concentrations below
40% will decrease the freeze and
corrosion protection characteristics of
the engine coolant and may cause
engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine protection.
AUTOMATIC TRANSMISSION
FLUID CHECK
The automatic transmission does not have
a transmission fluid dipstick.
218
Focus (CDH) Canada/United States of America, enUSA, First Printing Maintenance

Have an authorized dealer check and
change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 336). Your
transmission does not consume fluid.
However, if the transmission slips, shifts
slowly or if you notice a sign of leaking
fluid, contact an authorized dealer.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
BRAKE FLUID CHECK WARNINGS
Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death. Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death. Do not allow the fluid to touch your
skin or eyes. If this happens, rinse the
affected areas immediately with
plenty of water and contact your physician. A fluid level between the
MAX and
MIN lines is within the normal
operating range and there is no need
to add fluid. A fluid level not in the normal
operating range could compromise the
performance of the system. Have your
vehicle checked immediately. To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.
Only use fluid that meets Ford
specifications.
CLUTCH FLUID CHECK -
MANUAL TRANSMISSION
The clutch and brake systems share the
same fluid reservoir. See
Brake Fluid
Check (page 219).
WASHER FLUID CHECK
When adding fluid, use a mixture of washer
fluid and water to help prevent freezing in
cold weather and improve the cleaning
capability. For information on fluid dilution,
refer to the product instructions.
Note: The reservoir supplies the front and
rear washer systems.

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.
CHANGING THE 12V BATTERY
WARNINGS
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 correct
ventilation. 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. 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. Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. Your vehicle has a Motorcraft®
maintenance-free battery which normally
does not require additional water during
its life of service. Note:
If your vehicle's battery has a cover
or shield, make sure it is reinstalled after the
battery has been cleaned or replaced.
Note: See an authorized dealer for low
voltage battery access, testing, or
replacement.
When a low voltage battery replacement
is necessary, see an authorized dealer to
replace the low voltage battery with a Ford
recommended replacement low voltage
battery that matches the electrical
requirements of the vehicle.
To ensure proper operation of the battery
management system (BMS), do not allow
a technician to connect any electrical
device ground connection directly to the
low voltage battery negative post. A
connection at the low voltage battery
negative post can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
Note: If a person adds electrical or
electronic accessories or components to the
vehicle, the accessories or components may
adversely affect the low voltage battery
performance and durability and may also
affect the performance of other electrical
systems in the vehicle.
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.
If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush. You
can neutralize the acid with a solution of
baking soda and water.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
that matches the electrical requirements
of the vehicle.

Because your vehicle
’s engine is
electronically-controlled by a computer,
some engine control settings are
maintained by power from the low voltage
battery. Some engine computer settings,
like the idle trim and fuel trim strategy,
optimize the driveability and performance
of the engine. Some other computer
settings, like the clock and radio station
presets, are also maintained in memory by
power from the low voltage battery. When
a technician disconnects and connects the
low voltage battery, these settings are
erased. Complete the following procedure
in order to restore the settings:
1. With the vehicle at a complete stop, set the parking brake.
2. Shift into park (P).
3. Switch off all accessories.
4. Fully press the brake pedal and start the vehicle.
5. Run the engine until it reaches normal operating temperature. While the
engine is warming up, complete the
following: Reset the clock. See Audio
System (page 278). Reset the power
windows bounce-back feature. See
Windows and Mirrors
(page 81).
Reset the radio station presets. See
Audio System
(page 278).
6. Allow the engine to idle for at least one
minute. If the engine turns off, press
the accelerator pedal to start the
engine.
7. While the engine is running, press the brake pedal and shift into neutral (N).
8. Allow the engine to run for at least one
minute by pressing on the accelerator
pedal.
9. Drive the vehicle at least 12 mi (20 km)
to completely relearn the idle and fuel
trim strategy. Note:
If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
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
Note:
If streaks or smears appear on the
windshield, clean the windshield and the
wiper blades.
See Cleaning the Windows
and Wiper Blades (page 236). If that does
not resolve the issue, install new wiper
blades.
