WARNINGS
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. 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/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.
261
MKZ (CC9) Maintenance
2. Shift the transmission into P.
3. Turn off all accessories.
4. Step on 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 309). Reset the power
windows bounce-back feature. See
Windows and Mirrors (page 83). Reset
the radio station presets.
See Audio
System (page 309).
6. Allow the engine to idle for at least one
minute. If the engine turns off, step on
the accelerator to start the engine.
7. While the engine is running, step on the brake pedal and shift the
transmission to N.
8. Allow the engine to run for at least one
minute by pressing on the accelerator
pedal.
9. Drive the vehicle at least 10 miles (16 kilometers) 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.
Note: 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. Note:
It is recommended that the negative
battery cable terminal be disconnected
from the battery if you plan to store your
vehicle for an extended period of time.
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
The wiper arms can be manually moved
when the ignition is off. This allows for
ease of blade replacement and cleaning
under the blades.
1. Pull the wiper blade and arm away
from the glass. 262
