Fluid levels above the safe range may
result in transmission failure. An overfill
condition of transmission fluid may cause
shift and engagement concerns, and
possible damage.

High fluid levels can be caused by an
overheating condition.

Adjusting Automatic Transmission
Fluid Levels

Note: Use of a non-approved automatic
transmission fluid may cause internal
transmission component damage.

Before adding any fluid, make sure the
correct type is used. The type of fluid used
is normally indicated on:

•

the dipstick handle.

•

See Capacities and Specifications
(page 411).

If necessary, add fluid in 8 fl oz (250 ml)
increments through the filler tube until the
level is correct.

Type B

E163746

If an overfill occurs, excess fluid should be
removed by a qualified technician.

Note: An overfill condition of transmission
fluid may cause shift and engagement
concerns, and possible damage.

339

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.

TRANSFER CASE FLUID
CHECK

(If Equipped)

E164246

1.

Clean the filler plug.

2. Remove the filler plug and inspect the

fluid level.

3. Add only enough fluid through the filler

opening so that the fluid level is at the
bottom of the opening.

Only use fluid that meets Ford
specifications. See Capacities and
Specifications (page 411).

BRAKE FLUID CHECK

WARNINGS

Do not use any fluid other than the
recommended brake fluid as this will
reduce brake efficiency. Use of

incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death.

Only use brake fluid from a sealed
container. Contamination with dirt,
water, petroleum products or other

materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death.

Do not allow the fluid to touch your
skin or eyes. If this happens, rinse the
affected areas immediately with

plenty of water and contact your physician.

A fluid level between the MAX and
MIN lines is within the normal
operating range and there is no need

to add fluid. A fluid level not in the normal
operating range could compromise the
performance of the system. Have your
vehicle checked immediately.

E170684

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 411).

POWER STEERING FLUID
CHECK

Check the power steering fluid. See
Scheduled Maintenance (page 567). If
adding fluid is necessary, use only
MERCON LV ATF

Note: This procedure is for vehicles with
gasoline engines. Vehicles with diesel
engines are similar. See Under Hood
Overview in your diesel supplement.

Check the fluid level when it is at ambient
temperature.

1.

Check the fluid level in the reservoir. It
should be between the MIN and MAX
range. Do not add fluid if the level is
within this range.

2. If the fluid level is low, add fluid to bring

the fluid level up to between the MIN
and MAX range.

3. Switch the engine on.
4. While the engine idles, turn the steering

wheel left and right several times.

5. Switch the engine off.
6. Recheck the fluid level in the reservoir.

Do not add fluid if the level is between
the MIN and MAX range.

7.

If the fluid is low, add fluid in small
amounts, continuously checking the
level until it is between the MIN and
MAX range. For proper fluid type, See
Capacities and Specifications (page
411). Be sure to put the cap back on the
reservoir.

WASHER FLUID CHECK

WARNING

If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze

protection. Failure to use washer fluid with
antifreeze protection in cold weather could
result in impaired windshield vision and
increase the risk of injury or accident.

Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See Capacities and
Specifications (page 411).

341

State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle’s paint finish, wiper blades or
washer system.

DRAINING THE FUEL FILTER
WATER TRAP - 6.7L DIESEL

WARNING

Do not dispose of fuel in the
household refuse or the public
sewage system. Use an authorized

waste disposal facility.

Your vehicle has a diesel fuel conditioner
module. The module is mounted between
the outboard side of the fuel tank and the
frame rail.

Note: The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models.

You should drain water from the
module assembly whenever the
warning light illuminates or a

message appears in the information
display advising you to drain the water
separator. This occurs when approximately
6.76 fl oz (200 ml) of water accumulates
in the module. If you allow the water level
to exceed this level, the water may pass
through to the engine and may cause fuel
injection equipment damage.

Draining the Diesel Fuel
Conditioner Module

1.

Switch the engine off.

2. Access the underside of your vehicle.
