WARNING:Never connect any trailer lighting to the vehicle’s
taillamp circuits, because it may damage the electrical system
resulting in fire. Contact your authorized dealer as soon as possible for
assistance in proper trailer tow wiring installation. Additional electrical
equipment may be required.
Driving while you tow
When towing a trailer:
•To ensure proper “break-in” of powertrain components, do not trailer
tow during the first 1,000 miles (1,600 km) of a new vehicle.
•To ensure proper “break-in” of powertrain components during the first
500 miles (800 km) of trailer towing, drive no faster than 70 mph
(113 km/h) with no full throttle starts.
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. For additional information, refer toAutomatic
transmission operationin theDrivingchapter.
•Under extreme conditions with large frontal trailers, high outside
temperatures and highway speeds, the coolant gauge may indicate
higher than normal coolant temperatures. If this occurs, reduce speed
until the coolant temperature returns to the normal range. Refer to
Engine coolant temperature gaugein theInstrument Cluster
chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor 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 will clear 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 will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 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).
•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.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•causing internal damage to the components.
•affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow this guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.

Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) jumper cable to the positive (+) terminal of
the discharged battery.
Note:In the illustrations,lightning boltsare used to designate the
assisting (boosting) battery.

WINDSHIELD WASHER FLUID
Add fluid to fill the reservoir if the
level is low. In very cold weather, do
not fill the reservoir completely.
Only use a washer fluid that meets Ford specification WSB-M8B16–A2.
Do not use any special washer fluid such as windshield water repellent
type fluid or bug wash. They may cause squeaking, chatter noise,
streaking and smearing. Refer to theMaintenance product
specifications and capacitiessection in this chapter.
State or local regulations on volatile organic compounds may restrict the
use of methanol, a common windshield washer antifreeze additive.
Washer fluids containing non-methanol antifreeze agents should be used
only if they provide cold weather protection without damaging the
vehicle’s paint finish, wiper blades or washer system.
WARNING:If you operate your vehicle in temperatures below
40°F (5°C), use washer fluid with antifreeze protection. Failure
to use washer fluid with antifreeze protection in cold weather could
result in impaired windshield vision and increase the risk of injury or
accident.
Do not put washer fluid in the engine coolant reservoir. Washer
fluid placed in the cooling system may harm engine and cooling
system components.
Checking and adding washer fluid for the liftgate
Washer fluid for the liftgate is supplied by the same reservoir as the
windshield.

Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water.When the engine is cool,add the mixture to the
coolant reservoir until the appropriate fill level is obtained.
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.
•Add Motorcraft Premium Gold Engine Coolant or equivalent
meeting Ford specification WSS-M97B51-A1.Refer to
Maintenance product specifications and capacitiesin this chapter.
Note:Use of Motorcraft Cooling System Stop Leak Pellets or an
equivalent product meeting Ford specification WSS-M99B37-B6, may
darken the color of Motorcraft Premium Gold Engine Coolant from
yellow to golden tan.
•Do not add/mix an orange-colored, extended life coolant such
as Motorcraft Specialty Orange Engine Coolant, meeting Ford
specification WSS-M97B44-D, or DEX-COOL
brand with the
factory-filled coolant.Mixing Motorcraft Specialty Orange Engine
Coolant or any orange-colored extended life product such as
DEX-COOL
brand with your factory filled coolant can result in
degraded corrosion protection.
•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 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.
