General Hints
Note: Prolonged use of recirculated
air may cause the windows to fog up.
Note: You may feel a small amount of
air from the footwell air vents
regardless of the air distribution setting.
Note: To reduce humidity build-up
inside your vehicle, do not drive with
the system switched off or with
recirculated air always switched on.
Note: Do not place objects under the
front seats as this may interfere with
the airflow to the rear seats. Note:
Remove any snow, ice or leaves
from the air intake area at the base of
the windshield.
Automatic Climate Control
Note: Do not adjust the settings when
your vehicle interior is extremely hot or
cold. The system automatically adjusts
to the previously stored settings. For
the system to function efficiently, the
instrument panel and side air vents
should be fully open.
Note: At low ambient temperatures
with AUTO selected, the system directs
air toward the windshield and side
windows for as long as the engine
remains cold.
Note: When you switch the system off,
outside air cannot enter your vehicle.

The braking system of the tow
vehicle is rated for operation at the
GVWR not GCWR.
Separate functioning brake
systems are required for safe
control of towed vehicles and
trailers weighing more than 1500
pounds (680 kilograms) when
loaded.
Trailer Lamps
Trailer lamps are required on most
towed vehicles. Make sure all running
lights, brake lights, turn signals and
hazard lights are working. Contact
your authorized dealer or trailer rental
agency for proper instructions and
equipment for hooking up the lamps.
Before Towing a Trailer
Practice turning, stopping and
backing-up to get the feel of the
vehicle-trailer combination before
starting on a trip. When turning, make
wider turns so the trailer wheels clear
curbs and other obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500
miles (800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical
connections and trailer wheel lug
nuts thoroughly after you have
traveled 50 miles (80 kilometers). •
When stopped in congested or
heavy traffic during hot weather,
place the gearshift in position P to
aid engine and transmission
cooling and to help A/C
performance.
• Turn off the speed control with
heavy loads or in hilly terrain. The
speed control may turn off
automatically when you are towing
on long, steep grades.
• Shift to a lower gear when driving
down a long or steep hill. Do not
apply the brakes continuously, as
they may overheat and become
less effective.
• If your transmission is equipped
with a grade assist or Tow/Haul
feature, use this feature when
towing. This provides engine
braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping
with a trailer attached. Anticipate
stops and brake gradually.

Towing

Note:
For best results, coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your
authorized dealer. Ford does not
recommend the use of hydrometers or
coolant test strips for measuring
coolant concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine
coolant or antifreeze or windshield
washer fluid outside of its specified
function and vehicle location.
Adding Engine Coolant WARNINGS
Do not add engine coolant when
the engine is hot. Steam and
scalding liquids released from a hot
cooling system can burn you badly.
Also, you can be burned if you spill
coolant on hot engine parts. Do not put engine coolant in the
windshield washer fluid
container. If sprayed on the
windshield, engine coolant could
make it difficult to see through the
windshield. To reduce the risk of personal
injury, make sure the engine is
cool before unscrewing the coolant
pressure relief cap. The cooling
system is under pressure; steam and
hot liquid can come out forcefully
when the cap is loosened slightly. Do not add coolant further than
the MAX mark. Note:
Do not use stop leak pellets,
cooling system sealants, or additives
as they can cause damage to the
engine cooling or heating systems. This
damage would not be covered under
your vehicle ’s warranty.
Note: During normal vehicle operation,
the engine coolant may change color
from orange to pink or light red. As long
as the engine coolant is clear and
uncontaminated, this color change
does not indicate the engine coolant
has degraded nor does it require the
engine coolant to be drained, the
system to be flushed, or the engine
coolant to be replaced.
• Do not mix different colors or types
of coolant in your vehicle. Make
sure the correct coolant is used.
Mixing of engine coolants may
harm your engine ’s cooling system.
The use of an improper coolant
may harm engine and cooling
system components and may void
the warranty. Use prediluted
engine coolant meeting the Ford
specification. See Capacities and
Specifications (page 325).
• In case of emergency, a large
amount of water without engine
coolant may be added in order to
reach a vehicle service location. In
this instance, the cooling system
must be drained, chemically
cleaned with Motorcraft®
Premium Cooling System Flush,
and refilled with prediluted engine
coolant as soon as possible. Water
alone (without engine coolant)
can cause engine damage from
corrosion, overheating or freezing.
269
Maintenance

•
Do not use alcohol, methanol,
brine or any engine coolants mixed
with alcohol or methanol
antifreeze (coolant). Alcohol and
other liquids can cause engine
damage from overheating or
freezing.
• Do not add extra inhibitors or
additives to the coolant. These can
be harmful and compromise the
corrosion protection of the engine
coolant.
Unscrew the cap slowly. Any pressure
will escape as you unscrew the cap.
Add prediluted engine coolant
meeting the Ford specification. See
Capacities and Specifications
(page 325).
Whenever coolant has been added,
the coolant level in the coolant
reservoir should be checked the next
few times you drive the vehicle. If
necessary, add enough prediluted
engine coolant to bring the coolant
level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not
recommend the use of recycled
engine coolant since a Ford-approved
recycling process is not yet available.
Always dispose of used automotive
fluids in a responsible manner. Follow
your community ’s regulations and
standards for recycling and disposing
of automotive fluids. Severe Climates
If you drive in extremely cold climates:
•
It may be necessary to have a Ford
authorized dealer increase the
coolant concentration above 50%.
• A coolant concentration of 60%
will provide improved freeze point
protection. Engine coolant
concentrations above 60% will
decrease the overheat protection
characteristics of the engine
coolant and may cause engine
damage
If you drive in extremely hot climates:
• It may be necessary to have a Ford
authorized dealer decrease the
coolant concentration to 40%.
• A coolant concentration of 40%
will provide improved overheat
protection. Engine coolant
concentrations below 40% will
decrease the corrosion/freeze
protection characteristics of the
engine coolant and may cause
engine damage.
Vehicles driven year-round in
non-extreme climates should use
prediluted engine coolant for
optimum cooling system and engine
protection.

Maintenance

What you Should Know About
Fail-Safe Cooling
If the engine coolant supply is
depleted, this feature allows the
vehicle to be driven temporarily before
incremental component damage is
incurred. The
“fail-safe” distance
depends on ambient temperatures,
vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the
engine coolant temperature gauge
will move to the red (hot) area and: The coolant temperature
warning light will illuminate.
The service engine soon
indicator will illuminate.
If the engine reaches a preset
over-temperature condition, the
engine will automatically switch to
alternating cylinder operation. Each
disabled cylinder acts as an air pump
and cools the engine.
When this occurs the vehicle will still
operate. However:
• The engine power will be limited.
• The air conditioning system will be
disabled.
Continued operation will increase the
engine temperature and the engine
will completely shut down, causing
steering and braking effort to increase. Once the engine temperature cools,
the engine can be re-started. Take
your vehicle to an authorized dealer
as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated WARNINGS
Fail-safe mode is for use during
emergencies only. Operate the
vehicle in fail-safe mode only as long
as necessary to bring the vehicle to
rest in a safe location and seek
immediate repairs. When in fail-safe
mode, the vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without
warning, potentially losing engine
power, power steering assist, and
power brake assist, which may
increase the possibility of a crash
resulting in serious injury. Never remove the coolant
reservoir cap while the engine is
running or hot. You have limited engine power when
in the fail-safe mode, so drive the
vehicle with caution. The vehicle will
not be able to maintain high-speed
operation and the engine will run
rough. Remember that the engine is
capable of completely shutting down
automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely
possible and turn off the engine.
2. Arrange for the vehicle to be taken
to an authorized dealer.

Maintenance

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.
1. Drive the vehicle 20 miles (30 kilometers) or until it reaches
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 a minimum of
10 seconds for each gear to
engage.
4. Put the gearshift lever in P (Park)
and leave the engine running. Note:
You will need to move the air
filter assembly to access the
transmission dipstick.
5. Remove the dipstick, wiping it clean with a clean, dry lint free rag.
If necessary, refer to Under hood
overview in this chapter for the
location of the dipstick.
6. Install the dipstick making sure it
is fully seated in the filler tube by
turning it to the locked position.
7. Remove the dipstick and inspect the fluid level. The fluid should be
in the designated areas for normal
operating temperature.
Moving the Air Filter Assembly
(Accessing the Dipstick) WARNING
Do not run engine with the air
filter disconnected.
