accurate fluid check, drive the vehicle
until it is warmed up (approximately
20 miles [30 kilometers]). If your
vehicle has been operated for an
extended period at high speeds, in city
traffic during hot weather or pulling a
trailer, the vehicle should be turned off
until normal operating temperatures
are reached to allow the fluid to cool
before checking. Depending on vehicle
use, cooling times could take up to 30
minutes or longer.
Refer to your scheduled maintenance
information for scheduled intervals
for fluid checks and changes. Your
transmission does not consume fluid.
However, the fluid level should be

Checking the fluid level
Low fluid level
If the fluid level is below the MIN range
of the dipstick, add fluid to reach the
hash mark level.
Note:
If the fluid level is below the MIN
level, do not drive the vehicle. An
underfill condition may cause shift or
engagement concerns or possible
damage.
Correct fluid level The transmission fluid should be
checked at normal operating
temperature 180°F-200°F
(82°C-93°C) on a level surface. The
normal operating temperature can be
reached after approximately 20 miles
(30 kilometers) of driving.
The transmission fluid level should be
targeted within the cross-hatch area
if at normal operating temperature
180°F-200°F (82°C-93°C). High fluid level
If the fluid level is above the MAX
range of the dipstick, remove fluid to
reach the hashmark level.
Note:
Fluid level above the MAX level
may cause shift or engagement
concerns or possible damage. High
fluid levels can be caused by an
overheating condition. If your vehicle
has been operated for an extended
period at high speeds, in city traffic
during hot weather or pulling a trailer,
the vehicle should be turned off until
normal operating temperatures are
reached. Depending on vehicle use,
cooling times could take up to 30
minutes or longer.

MaintenanceE158842 E158843 E158844 E158845

Before adding any fluid, make sure the
correct type is used. The type of fluid
used is normally indicated on the
dipstick and also in the Technical
Specifications section in this chapter.
Note:
An overfill condition of
transmission fluid may cause shift or
engagement concerns or possible
damage.
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. Reinstall
the air filter assembly. After the fluid
level has been checked and adjusted
as necessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filter assembly to the rubber hose.
3. Rotate the air filter assembly 90 degrees clockwise without
disconnecting the sensor.
4. Seat the air filter assembly back into the grommets by pushing
down on the air filter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that
attach air filter assembly to the
front of the vehicle. 7.
Install the bolt cover (if equipped).
8. Reinstall the harness retaining clip
into the front of the air filter
assembly.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAX
lines are within the normal operating
range; there is no need to add fluid. If
the fluid levels are outside of the
normal operating range, the
performance of the system could be
compromised; seek service from your
authorized dealer immediately.
POWER STEERING FLUID
CHECK
Your vehicle is equipped with an
electric power steering (EPS) system.
There is no fluid reservoir to check or
fill.
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.

MaintenanceE158846

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.
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.
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.
