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 and/or engagement concerns and/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.
Adjusting Automatic Transmission Fluid Levels
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 theTechnical
specificationssection in this chapter.
Note:Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 1/2 pint
(250 ml) increments through the
filler tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
Note:An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/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.
For vehicles equipped with the EcoBoost engine, 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.

Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and foreign material contamination should be inspected
immediately by a qualified expert, such as the factory-trained technicians
at your dealership. Your vehicle’s oils and fluids should be changed at the
specified intervals or in conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle sub-systems during scheduled
maintenance. It is critical that systems are flushed only with new fluid
that is the same as that required to fill and operate the system, or using
a Ford-approved flushing chemical.
Owner Checks and Services
Certain basic maintenance checks and inspections should be performed
every month or at six month intervals.
Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure.
Windshield washer fluid level.
Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary.
Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if
necessary.
Parking brake for proper operation.
Safety belts and seat latches for wear and function.
Safety warning lamps (brake, ABS, airbag, safety belt) for operation.
Washer spray and wiper operation. Clean or replace blades as
necessary.
