Trailer brakes
Electric brakes and manual, automatic or surge-type brakes are safe if
installed properly and adjusted to the manufacturer’s specifications. The
trailer brakes must meet local and Federal regulations.
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.
The towing vehicle braking system is rated for operation at the
GVWR, not the GCWR.
Separate functioning brake systems are required for safe control
of towed vehicles and trailers weighing more than 1500 lb.
(680 kg) when loaded.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure 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 trailer lamps.
Driving while you tow
When towing a trailer:
•Keep your speed no faster than 70 mph (113 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.
•Anticipate stops and brake gradually.
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.

When the engine is cold, check the
level of the engine coolant in the
reservoir.
•The engine coolant should be at the “FULL COLD” level or within the
“COLD FILL RANGE” as listed on the engine coolant reservoir
(depending upon application).
•Refer toscheduled maintenance informationfor service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant, antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
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.

POWER STEERING FLUID
Check the power steering fluid.
Refer toscheduled maintenance
informationfor the service interval
schedules.
1. Start the engine and let it run until it reaches normal operating
temperature (the engine coolant temperature gauge indicator will be
near the center of the normal area between H and C).
2. While the engine idles, turn the steering wheel left and right several
times.
3. Turn the engine off.
4. Check the fluid level on the
dipstick. It should be between the
arrows in the FULL range on the
side of the dipstick with the words
MAX. HOT at the top. Do not add
fluid if the level is within this range.
5. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL range. Be sure to put the dipstick
back in the reservoir.
Refer toMaintenance product specifications and capacitiesin this
chapter for the proper fluid type.

master cylinder. This condition is normal and in no way affects the
operation of the brake system. It does not require any service.
1. Clean the reservoir cap before removal to prevent dirt or water from
entering the reservoir.
2. Visually inspect the fluid level.
3. If necessary, add brake fluid from a clean un-opened container until
the level reaches MAX (Hydroboost system only). Do not fill above this
line.
•For vehicles with the Hydromax
brake system, add fluid to the
FILL TO BOTTOM OF RINGS
mark located at the top of the
reservoir. Do not fill above this
line.
4. Use only a brake fluid listed previously (DOT 3 or Super DOT 4
depending on brake system) and that is certified to meet Ford
specifications. Refer toMaintenance product specifications and
capacitiesin this chapter.
WARNING:Carefully read cautionary information on product
label. For MEDICAL EMERGENCY INFORMATION contact a
physician or Poison Control Center immediately; on Ford-Motorcraft
products call: 1-800-959-3673 (FORD). Failure to follow these
instructions may result in personal injury.
WARNING:Use of any brake fluid other than that indicated for
your brake system will cause permanent damage.
WARNING:Do not let the reservoir for the master cylinder run
dry. This may cause the brakes to fail.
Brake system fluid should be replaced on a regular basis to maintain
optimum braking performance, especially under heavy-duty driving
conditions such as frequent steep grades or heavy towing loads. Refer to
scheduled maintenance informationfor the service interval schedules.

Adjusting automatic transmission fluid levels
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and also in the
Maintenance product specifications and capacitiessection in this
chapter.
Use of a non-approved automatic transmission fluid may cause
internal transmission component damage.
If necessary, add fluid in 1/2 pint (250 ml) increments through the filler
tube until the level is correct.
If an overfill occurs, excess fluid
should be removed by an authorized
dealer.
An overfill condition of
transmission fluid may cause shift and/or engagement concerns
and/or possible damage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
Automatic transmission fluid filter
The Torqshift automatic transmission is equipped with a serviceable
transmission fluid filter located inside the transmission bottom pan.
Refer toscheduled maintenance informationfor service intervals for
automatic transmission fluid and transmission filter.
For transmission filter maintenance, see your authorized dealer.

based on cooler size and if equipped with in-tank cooler. The amount of
transmission fluid and fluid level should be set by the indication on the
dipstick’s normal operating range.
4Automatic transmissions that require MERCONLV should only use
MERCONLV fluid. Refer toscheduled maintenance informationto
determine the correct service interval. Use of any fluid other than the
recommended fluid may cause transmission damage.
