Operating tips
•To reduce fog build-up on the windshield during humid weather,
select
(defrost) or(floor/defrost). Temperature and/or fan
speed can also be increased to improve clearing.
•To reduce humidity build-up inside the vehicle: do not drive with the
system off or with recirculated air engaged and A/C off.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been “aired out.”
•A small amount of air may be felt from the floor vent regardless of the
air distribution setting that is selected.
If you are driving during extreme high ambient temperatures and idling
for extended periods of time in gear, it is recommended to run the A/C
in the MAX A/C position, adjust the blower fan speed to the lowest
setting and put the vehicle’s transmission into the P (Park) position to
continue to receive cool air from your A/C system.

•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Use a lower gear to eliminate excessive shifting and assist in
transmission cooling.
•Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
Servicing after towing
If you tow a trailer for long distances, your vehicle requires more
frequent service intervals. Refer to theScheduled Maintenance Guide
chapter for more information.
Trailer towing tips
•Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels clears curbs and other obstacles.
•Allow more distance for stopping with a trailer attached.
•If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
•
The trailer tongue weight should be 10–15% of the loaded trailer weight.
•If you are towing a trailer frequently in hot weather, hilly conditions,
at GCW, or any combination of these factors, consider refilling your
rear axle with synthetic gear lube if not already so equipped. Refer to
Lubricant specificationsin theMaintenance and Specifications
chapter for the lubricant specification. Remember that regardless of
the rear axle lube used, do not tow a trailer for the first 500 miles
(800 km) of a new vehicle, and that the first 500 miles (800 km) of
towing be done at no faster than 70 mph (112 km/h) with no full
throttle starts.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•
To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park) (if
available on your automatic transmission) or N (Neutral) (manual
transmissions and automatic transmissions withoutaP[Park] position).
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
Fan clutches
Your vehicle’s cooling system is equipped with a viscous fan clutch
which:
•Helps control cooling, increase performance, improve fuel economy
and reduce noise.
•Is controlled by bimetallic spring sensors. Do not tamper with these
sensors as this may change their calibration or keep the fan clutch
from operating at all.
WARNING:Stay clear of the fan/fan area while the engine is
running or possible personal injury may occur.
ENGINE COOLANT (GAS ENGINE ONLY)
Checking engine coolant
The concentration and level of engine coolant should be checked at the
intervals listed in your scheduled maintenance information. The coolant
concentration should be maintained at 50/50 coolant and distilled water.
For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300-ROB75240E available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentration. The level of coolant should
be maintained at the FULL COLD level or within the COLD FILL RANGE
in the coolant reservoir. If the level falls below, add coolant per the
instructions in theAdding engine coolantsection.
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•Improved freeze protection.
•Improved boiling protection.
•Protection against rust and other forms of corrosion.
•Proper function of calibrated gauges.
When the engine is cold, check the level of the engine coolant in the
reservoir.

•The engine coolant should be at the FULL COLD level, or within the
COLD FILL or MIN / MAX range as listed on the engine coolant
reservoir (depending upon application).
•Refer to your scheduled maintenance information for service interval
schedules.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.
WARNING: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.
WARNING: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.
•DO NOT MIXdifferent 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. Refer toMaintenance product specifications and
capacitiesin this chapter.
Note:Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
