AUTOMATIC
TRANSMISSION FLUID
CHECK
6F35/HF35 transmission (If
Equipped)
Note: Transmission fluid should be
checked by an authorized dealer. If
required, fluid should be added by an
authorized dealer.
The automatic transmission does not
have a transmission fluid dipstick.
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
checked if the transmission is not
working properly, (For example: if the
transmission slips or shifts slowly) or
if you notice some sign of fluid
leakage. See Scheduled
Maintenance (page 436).
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.

Equipped)
WARNINGS
The dipstick cap and surrounding
components may be hot; gloves
are recommended.
WARNINGS
Use gloves when moving the air
filter assembly. Components will
be hot.
Note: Automatic transmission fluid
expands when warmed. To obtain an
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
checked if the transmission is not
working properly. For example, if the
transmission slips or shifts slowly or
if you notice some sign of fluid
leakage.

Low fluid level
E158842
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
E158843
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).
278
Maintenance

High fluid level
E158844
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.
Adjusting Automatic Transmission
Fluid Levels
E158845
E158846
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.

Maintenance

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.
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.
Because your vehicle’s engine is
electronically-controlled by a
computer, some engine control
settings are maintained by power
from the low voltage battery. Some
engine computer settings, like the idle
trim and fuel trim strategy, optimize
the driveability and performance of
the engine. Some other computer
settings, like the clock and radio
station presets, are also maintained
in memory by power from the low
voltage battery. When a technician
disconnects and connects the low
voltage battery, these settings are
erased. Complete the following
procedure in order to restore the
settings:
1. With the vehicle at a completestop, set the parking brake.
2. Shift the transmission into P.
3. Turn off all accessories.
4. Step on the brake pedal and start the vehicle. 5. Run the engine until it reaches
normal operating temperature.
While the engine is warming up,
complete the following: Reset the
clock. See Audio System (page
124). Reset the power windows
bounce-back feature. See
Windows and Mirrors (page 88).
Reset the radio station presets.
See Audio System (page 124).
6. Allow the engine to idle for at least one minute. If the engine turns off,
step on the accelerator to start the
engine.
7. While the engine is running, step on the brake pedal and shift the
transmission to N.
8. Allow the engine to run for at least one minute by pressing on the
accelerator pedal.
9. Drive the vehicle at least 10 miles (16 kilometers) to completely
relearn the idle and fuel trim
strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy,
the idle quality of your vehicle may be
adversely affected until the engine
computer eventually relearns the idle
trim and fuel trim strategy.
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.

Maintenance

• Use commercial car washingequipment.
• Use snow chains on the end of the vehicle with the dissimilar spare
wheel and tire assembly.
The usage of a full-size dissimilar
spare wheel and tire assembly can
lead to impairment of the following:
• Handling, stability and braking performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• All-wheel driving capability (if applicable).
• Load leveling adjustment (if applicable).
When driving with the full-size
dissimilar spare wheel and tire
assembly additional caution should
be given to:
• Towing a trailer.
• Driving vehicles equipped with a camper body.
• Driving vehicles with a load on the cargo rack.
Drive cautiously when using a full-size
dissimilar spare wheel and tire
assembly and seek service as soon as
possible.Tire Change Procedure
WARNINGS
When one of the front wheels is
off the ground, the transmission
alone will not prevent the vehicle from
moving or slipping off the jack, even if
the transmission selector lever is in
position P.
To help prevent the vehicle from
moving when you change a tire,
be sure to place the transmission
selector lever in position P, set the
parking brake and block (in both
directions) the wheel that is
diagonally opposite (other side and
end of the vehicle) to the tire being
changed.
Never get underneath a vehicle
that is supported only by a jack.
If the vehicle slips off the jack, you or
someone else could be seriously
injured.
Do not attempt to change a tire
on the side of the vehicle close
to moving traffic. Pull far enough off
the road to avoid the danger of being
hit when operating the jack or
changing the wheel.
Always use the jack provided as
original equipment with your
vehicle. If using a jack other than the
one provided as original equipment
with your vehicle, make sure the jack
capacity is adequate for the vehicle
weight, including any vehicle cargo or
modifications.
