Ford Focus (2017 year). Manual — part 55

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.

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 282). Reset the power
windows bounce-back feature. See
Windows and Mirrors (page 81).
Reset the radio station presets. See
Audio System (page 282).

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.
