Maintenance
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.

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. See Capacities and
Specifications (page 297).
WARNING: Battery posts,
terminals and related accessories
contain lead and lead compounds. Wash
hands after handling.
WARNING: For vehicles with
Auto-Start-Stop the battery requirement
is different. You must replace the battery
with one of exactly the same
specification.
CLUTCH FLUID CHECK
The clutch and brake systems share the
same fluid reservoir. See Brake Fluid
Check (page 249).
The battery is in the engine compartment.
See Under Hood Overview (page 238).
CHANGING THE 12V BATTERY
Your vehicle has a maintenance-free
battery. It does not require additional
water during service.
If the vehicle battery has a cover, make
sure you correctly install it after cleaning
or replacing the 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 correct ventilation.

top of the battery clean and dry and the
battery cables tightly fastened to the
battery terminals. If any corrosion is
present 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.
To disconnect or remove the battery, do
the following:
1. Apply the parking brake and switch the
ignition off.
2. Switch all electrical equipment off, for
example lights and radio.
3. Wait a minimum of two minutes before
disconnecting the battery.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note: If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
Note: The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty.
To maintain correct operation of the
battery management system, if you add
any electrical devices to your vehicle, do
not connect the ground connection directly
to the negative battery terminal. A
connection at the negative battery terminal
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to your vehicle this may
adversely affect battery performance,
durability and the performance of other
electrical systems on your vehicle.
4. Disconnect the negative battery cable
terminal.
5. Disconnect the positive battery cable
terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal
procedure.
Note: Before reconnecting the battery,
make sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened.
If you replace the battery make sure it
matches the electrical requirements of
your vehicle.
If you disconnect or replace the vehicle
battery, you must reset the following
features:
If you disconnect or replace the battery
and your vehicle has an automatic
transmission, it must relearn its adaptive
strategy. Because of this, the transmission
may shift firmly when first driven. This is
normal operation while the transmission
fully updates its operation to optimum
shift feel.
