Service Data Recording
Service data recorders in your vehicle are capable of collecting and
storing diagnostic information about your vehicle. This potentially
includes information about the performance or status of various systems
and modules in the vehicle, such as engine, throttle, steering or brake
systems. In order to properly diagnose and service your vehicle, Ford
Motor Company, Ford of Canada, and service and repair facilities may
access vehicle diagnostic information through a direct connection to your
vehicle when diagnosing or servicing your vehicle.
Event Data Recording
Other modules in your vehicle — event data recorders — are capable of
collecting and storing data during a crash or near crash event. The
recorded information may assist in the investigation of such an event.
The modules may record information about both the vehicle and the
occupants, potentially including information such as:
•how various systems in your vehicle were operating;
•whether or not the driver and passenger seatbelts were buckled;
•how far (if at all) the driver was depressing the accelerator and/or the
brake pedal;
•how fast the vehicle was traveling; and
•where the driver was positioning the steering wheel.
To access this information, special equipment must be directly connected
to the recording modules. Ford Motor Company and Ford of Canada do
not access event data recorder information without obtaining consent,
unless pursuant to court order or where required by law enforcement,
other government authorities or other third parties acting with lawful
authority. Other parties may seek to access the information
independently of Ford Motor Company and Ford of Canada.

Safety chains
Always connect the trailer’s safety chains to hook retainers on the
vehicle. To connect the trailer’s safety chains, cross the chains under the
trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric, manual, automatic or surge-type brakes, if compatible with the
vehicle, are safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Do not
connect trailer lamps directly to your vehicle’s tail lamps. This can cause
damage to your vehicle’s electrical system. See your authorized dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.
Driving while you tow
When towing a trailer:
•Keep your speed no faster than 70 mph (112 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make 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 to
Understanding the gearshift positions of the 4–speed automatic
transmissionin theDriving 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 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).
•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.
