TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING:Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of the vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components periodically during, and after, any towing operation.
RECOMMENDED TOWING WEIGHTS
Your vehicle is capable of towing a trailer up to 1000 lb (454 kg) gross
trailer weight with a maximum tongue load of 100 lb (45 kg).Do not
towwith the Boss 302, Boss 302 Laguna Seca, GT Deluxe or Shelby
GT500 models; they are not rated to tow a trailer.
ESSENTIAL TOWING CHECKS
Follow these guidelines to ensure safe towing:
•Do not tow a trailer until your vehicle has been driven at least
1000 miles (1600 kilometers).
•Consult your local motor vehicle laws for towing a trailer.
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
•Service your vehicle more frequently if you tow a trailer. Refer to your
scheduled maintenance information.
For load specification terms found on the label and instructions on
calculating your vehicle’s load, refer to theLoad Carryingchapter.
Remember to account for the trailer tongue weight as part of the vehicle
load when calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps onto the bumper or attaches to the
axle. Distribute the trailer load so 10–15% of the total trailer weight is on
the tongue.

Safety Chains
Always connect the safety chains to the vehicle’s hook retainers. To
connect the safety chains, cross them under the trailer tongue and allow
slack for turning corners.
If you use a rental trailer, follow the rental agency’s instructions.
Note:Never attach safety chains to the bumper.
Trailer Brakes
WARNING: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.
Electric brakes and manual, automatic or surge-type trailer brakes are safe
if installed properly and adjusted to the manufacturer’s specifications. The
trailer brakes must meet local and Federal regulations.
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. Ensure 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 will 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) and 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).
•Place the gearshift lever in P (Park) to aid in engine and transmission
cooling and A/C efficiency during hot weather while stopped in traffic.
•Turn off the speed control. 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 the grade assist 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.
•Avoid parking on a grade. However, if you must park on a grade, place
wheel chocks under the trailer’s wheels.
WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member of a roadside assistance program, your
roadside assistance service provider.
It is recommended that your vehicle be towed with a wheel lift and
dollies or flatbed equipment. Do not tow with a slingbelt. Ford Motor
Company has not approved a slingbelt towing procedure. If the vehicle is
towed incorrectly, or by any other means, vehicle damage may occur.

BREAKING-IN
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 1,000 miles (1,600 km) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating.
ECONOMICAL DRIVING
Fuel economy is affected by several things such as how you drive, the
conditions you drive under and how you maintain your vehicle.
There are some things to keep in mind that may improve your fuel
economy:
•Accelerate and slow down in a smooth, moderate fashion.
•Drive at steady speeds without stopping.
•Anticipate stops; slowing down may eliminate the need to stop.
•Combine errands and minimize stop-and-go driving.
•Close the windows for high-speed driving.
•Drive at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•Keep the tires properly inflated and use only the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduled maintenance.
There are also some things you may not want to do because they may
reduce your fuel economy:
•Sudden or hard accelerations.
•Rev the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on cold mornings.
•Use the air conditioner or front defroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal while driving.
Driving Hints203

•Drive a heavily loaded vehicle or tow a trailer.
•Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for
every 400 lb [180 kg] of weight carried).
•Add particular accessories to your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski racks).
•Drive with the wheels out of alignment.
DRIVING THROUGH WATER
WARNING:Drive through water in an emergency only, and not
as part of normal driving.
WARNING:Engine damage can occur if water enters the air
filter.
Note:Driving through deep water may allow water into the transmission
or air intake and can cause internal vehicle damage or cause it to stall.
Note:Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
wheel rims (for cars) or the bottom
of the hubs (for trucks).
When driving through water,
traction or brake capability may be
limited. Also, water may enter your
engine’s air intake and severely
damage your engine or your vehicle
may stall.
Wet brakes do not stop the vehicle
as quickly as dry brakes.

FUEL CUT-OFF SWITCH
WARNING:Failure to inspect and if necessary repair fuel leaks
after a collision may increase the risk of fire and serious injury.
Ford Motor Company recommends that the fuel system be inspected by
an authorized dealer after any collision.
In the event of a moderate to severe collision, this vehicle is equipped
with a fuel pump shut-off feature that stops the flow of fuel to the
engine. Not every impact will cause a shut-off.
Should your vehicle shut off after a collision, you may restart your
vehicle by doing the following:
1. Turn the ignition off and wait approximately 10 seconds.
2. Turn the ignition on.
3. Repeat steps 1 and 2 to re-enable fuel pump.
JUMP-STARTING THE VEHICLE
WARNING:The gases around the battery can explode if exposed
to flames, sparks, or lit cigarettes. An explosion could result in
injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission vehicle.
Automatic transmissions do not have push-start capability. Attempting to
push-start a vehicle with an automatic transmission may cause
transmission damage.
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 soft shifts, firm shifts or both. 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.
