FORD 2014 Focus v.1 - Manual (Page 242)

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.
To ensure proper operation of the battery management system (BMS),
any electrical devices that are added to the vehicle should not have their
ground connection made directly at the negative battery post. A connection
at the negative battery post can cause inaccurate measurements of the
battery condition and potential incorrect system operation.
Note: Electrical or electronic accessories or components added to the
vehicle by the dealer or the owner may adversely affect battery
performance and durability and may also affect the performance of other
electrical systems in the vehicle.
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.
When the battery is disconnected or a new battery installed, the
automatic transmission must relearn its adaptive strategy. As a result of
this, the transmission may shift firmly when first driven. This operation
is considered normal and 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.
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.
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.
