Hot weather operation
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
•Above normal coolant temperatures could be experienced while
driving in a transmission gear ratio which lugs the engine. To correct
this problem, engine speed should be increased by downshifting into
the next lower gear.
Restarting after running out of fuel
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and Specificationschapter.
Engine shutdown (diesel engine only)
Allow the engine to idle for three to five minutes before shutting it
down. The larger the engine, the greater the need for this idling period.
However, do not let the engine idle for more than 10 minutes.
GENERAL OPERATING INSTRUCTIONS
•Start the vehicle in motion by using the highest gear speed in the
transmission that lets the engine easily start the load without slipping
the clutch.
•Accelerate smoothly and evenly; rapid acceleration increases fuel
consumption without increasing engine performance.
•
When approaching a hill, press the accelerator smoothly to start the
incline at full power, then shift down as needed to maintain vehicle speed.
•When going down a hill, or long steep grades, prevent overspeeding of
the engine; normally, choose the same gear to descend the hill that
you use to ascend the hill. The engine governor has no control over
engine speed when it is being pushed by a loaded vehicle.
•Operate in a gear that permits an engine speed not in excess of the
maximum governed speed or high-idle RPM (no load).
•
Always shift to a lower gear at high altitudes to prevent engine smoking.
•Diesel engines:Allow the engine to idle for three to five minutes
before shutting it down; the larger the engine, the greater the need for
this idling period. However, do not let the engine idle for more than
10 minutes.

•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.

automotive batteries.
ENGINE COOLANT (DIESEL ENGINE ONLY)
Refer to your engine operator’s manual for engine coolant checking and
adding instructions.
Severe climates
If you drive in extremely cold climates (less than –34°F [–36°C]):
•It may be necessary to increase the coolant concentration
above 50%.
•NEVER increase the coolant concentration above 60%.
•Engine coolant concentrations above 60% decreases the
overheat protection characteristics of the engine coolant and
may cause engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle provides
adequate freeze protection at the temperatures in which you
drive in the winter months.
If you drive in extremely hot climates:
•It is still necessary to maintain the coolant concentration
above 40%.
•NEVER decrease the coolant concentration below 40%.
•Engine coolant concentrations below 40% decreases the
corrosion protection characteristics of the engine coolant and
may cause engine damage.
•Engine coolant concentrations below 40% decreases the freeze
protection characteristics of the engine coolant and may cause
engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle provides
adequate protection at the temperatures in which you drive.

•A large amount of water without engine coolant may be added, in case
of emergency, 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 a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
•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.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
distilled water to the FULL COLD level. For all other vehicles which have
a coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.
WARNING: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.
Add the proper mixture of coolant and water to the cooling system by
following these steps:
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.
4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.

5. Fill the coolant reservoir slowly with the proper coolant mixture, to
within the FULL COLD level, or within the COLD FILL or MIN / MAX
range as listed on the engine coolant reservoir (depending upon
application). If you removed the radiator cap in an overflow system, fill
the radiator until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
toChecking engine coolant). If the concentration is not 50/50, drain
some coolant and adjust the concentration. It may take several drains
and additions to obtain a 50/50 coolant concentration.
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 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.
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.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
toMaintenance product specifications and capacitiesin this chapter.
If your vehicle is equipped with a diesel engine,refer to your
operator’s manual.
Fill your engine coolant reservoir as outlined previously in theAdding
engine coolantsection.
