When driving through water, determine the depth; avoid water higher
than the bottom of the wheel rims (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even AWD vehicles can lose traction in slick mud. As
when you are driving over sand, apply the accelerator slowly and avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the engine, transmission, AWD System components or axles are
submerged in water, their fluids should be checked and changed, if
necessary.
Driving through deep water may damage the engine or
transmission.
If the front or rear axle is submerged in water, the axle lubricant and
PTU (Power Transfer Unit) lubricant should be checked and changed if
necessary.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
“Tread Lightly” is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest Service and the Bureau of Land
Management in encouraging you to help preserve our national forest and
other public and private lands by “treading lightly.”
Driving on hilly or sloping terrain
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down.Avoid driving crosswise or turning on steep
slopes or hills.A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.

BRAKE FLUID
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
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.
TRANSMISSION FLUID
Checking 6–speed automatic transmission fluid
Refer to yourscheduled maintenance informationfor 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, i.e., if the transmission slips or
shifts slowly or if you notice some sign of fluid leakage.
Checking automatic transmission fluid at normal operating
temperature (140°F-158°F [60°C-70°C])
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is warmed up
(approximately 20 miles [30 km]) until the engine coolant gauge
indicates normal operating temperature. 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 for about 30 minutes to allow fluid to cool before
checking.
1. Drive the vehicle 20 miles (30 km) or until the coolant gauge indicates
normal operating temperature.
2. Park the vehicle on a level surface and engage the parking brake.
3. With the parking brake engaged and your foot on the brake pedal,
start the engine and move the gearshift lever through all of the gear
ranges. Allow sufficient time for each gear to engage (approximately
10–15 seconds in each position).
4. Move the gearshift lever to P (Park) and leave the engine running.

5. Remove the dipstick, wiping it clean with a clean, dry, lint-free rag. If
necessary, refer toIdentifying components in the engine compartment
in this chapter for the location of the dipstick.
6. Install the dipstick making sure it is fully seated in the filler tube.
7. Remove the dipstick and inspect
the fluid level. The fluid should read
within the hot range on the dipstick
if at normal operating temperature
(140°F-158°F [60°C-70°C]).
Checking automatic transmission fluid at cool temperature
(59°F-77°F [15°C-25°C])
If a fluid check is necessary at a low
fluid temperature (59°F-77°F
[15°C-25°C]), perform the check
using the cold range on the dipstick.
However, the fluid must be
re-checked at the proper fluid temperature.
Low fluid level
Do not drive the vehicle if the fluid
level does not show at all on the
dipstick.
Driving the vehicle with less than
the recommended fluid level may result in transmission failure. An under
fill condition of transmission fluid may cause shift and/or engagement
concerns and/or possible damage to the transmission.
High fluid level
Fluid levels above the normal
operating range may result in
transmission failure. An overfill
condition of transmission fluid may
cause shift and/or engagement
concerns and/or possible damage to
the transmission.
High fluid levels can be caused by an overheating condition.
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 the
Maintenance product specifications and capacitiessection in this
chapter.

Note:Only one ATF fluid specification has been tested and approved for
use with the automatic 6-speed: Premium Automatic Transmission fluid.
Mercon fluids cannot be used with the automatic 6-speed without
damage or voiding warranty.
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.
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.
AIR FILTER
Refer toscheduled maintenance informationfor the appropriate
intervals for changing the air filter element.
When changing the air filter element, use only the air filter element
listed. Refer toMotorcraft part numbersin this chapter.
WARNING:To reduce the risk of vehicle damage and/or
personal burn injuries do not start your engine with the air
cleaner removed and do not remove it while the engine is running.
Changing the air filter element
1. Release the clamps that secure
the air filter housing cover.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the air filter housing.
4. Wipe the air filter housing and
cover clean to remove any dirt or
debris and to ensure good sealing.
