vehicle’s battery.
4. Remove the jumper cable from the positive (+) terminal of the
disabled vehicle’s battery.
After the disabled vehicle has been started and the jumper cables

WRECKER TOWING INSTRUCTIONS
Before moving the towed vehicle, check for adequate road clearance of
vehicle components. It is recommended the towed vehicle be unloaded
prior to being towed to reduce any abnormal load to the vehicle
components resulting from the towing procedures. Before towing, be
sure to fully release the parking brake. The spring-actuated type parking
brake can be reset by recharging the air system with at least 441 kPa (64
psi) of air. If the brake system will not retain air pressure, then the
spring brakes must be released manually. Refer toParking brakein the
Drivingchapter
Note:For towing, make sure the vehicle is securely connected to the
tow vehicle and the tow vehicle parking brakes are applied before
releasing the disabled vehicle’s spring brakes.

Roadside emergencies

In order to help you service your Ford vehicle, please have the following
information available when contacting the Commercial Vehicle Hotline:
•Your telephone number (home and business)
•The name of the dealer and the city where the dealership is located
•The year and make of your vehicle
•The date of vehicle purchase
•The current odometer reading
•The vehicle identification number (VIN)
If you still have a complaint involving a warranty dispute, you must
directly notify Ford in writing before pursuing remedies under your
state’s warranty laws. Ford is also allowed a final repair attempt in some
states.
GETTING ASSISTANCE OUTSIDE THE U.S AND CANADA
Before exporting your vehicle to a foreign country, contact the
appropriate foreign embassy or consulate. These officials can inform you
of local vehicle registration regulations and where to find unleaded fuel.
If you cannot find unleaded fuel or can only get fuel with an anti-knock
index lower than is recommended for your vehicle, contact a district or
owner relations/customer relationship office.
The use of leaded fuel in your vehicle without proper conversion may
damage the effectiveness of your emission control system and may cause
engine knocking or serious engine damage. Ford Motor Company/Ford of
Canada is not responsible for any damage caused by use of improper
fuel.
In the United States, using leaded fuel may also result in difficulty
importing your vehicle back into the U.S.
If your vehicle must be serviced while you are traveling or living in
Central or South America, the Caribbean, or the Middle East, contact the
nearest Ford dealership. If the dealership cannot help you, write or call:

PAINT CHIPS
Your dealer has touch-up paint and sprays to match your vehicle’s color.
Take your color code (printed on a sticker in the driver’s door jam) to
your dealer to ensure you get the correct color.
•Remove particles such as bird droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout before repairing paint chips.
•Always read the instructions before using the products.
ALUMINUM WHEELS AND COVERS
Aluminum wheel rims or covers are coated with a clearcoat paint finish.
In order to maintain their shine:
•Clean with Motorcraft Wheel and Tire Cleaner (ZC-37–A), which is
available from your dealer.
•Never apply any cleaning chemical to hot or warm wheel rims or
covers.
•Some automatic car washes may cause damage to the finish on your
wheel rims or covers. Chemical-strength cleaners, or cleaning
chemicals, in combination with brush agitation to remove brake dust
and dirt, could wear away the clearcoat finish over time.
•Do not use hydrofluoric acid-based or high caustic-based wheel
cleaners, steel wool, fuels or strong household detergent.
•To remove tar and grease, use Ford Extra Strength Tar and Road Oil
Removal (B7A-19520–AA), available from your dealer.
ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•Take care when using a power washer to clean the engine. The
high-pressure fluid could penetrate the sealed parts and cause
damage.
•Do not spray a hot engine with cold water to avoid cracking the
engine block or other engine components.
•Spray Motorcraft Engine Shampoo and Degreaser (ZC-20) on all parts
that require cleaning and pressure rinse clean.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
