and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
Power take off (PTO) capability (if equipped)
Some vehicles are equipped with Power Take Off (PTO) capability. These
vehicles have a special transmission case, internal components and
calibration for PTO usage.
The PTO can be used during mobile and stationary
continuous/intermittent applications.
Gasoline engine:
PTO operation is disabled while the vehicle is in Overdrive (the TCIL will
not be illuminated), in N (Neutral), during engine cranking. Transmission
upshift and downshift schedules will be reduced by about 15% and will
have a firmer shift feel during PTO mobile applications.
The PTO cannot be disabled while the transmission is in D (Drive)
(Overdrive position with Overdrive canceled), 2 (Second) or 1 (First).
Refer to theBody Builder’s Layout Bookfor recommended electrical
installation.
Diesel engine:
The Auxiliary Powertrain Control Module (APCM) will elevate the engine
speed to 1,200 RPM when in PTO mode. PTO operation will be disabled
in stationary drive idle conditions. For more information on the APCM
and PTO operation with the Diesel engine, refer to the APCM manual
supplied with your vehicle.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially if the depth is not known. Never drive through water
that is higher than the bottom of the hubs (for trucks) or the bottom of
the wheel rims (for cars). Traction or brake capability may be limited
and your vehicle may stall. Water may also enter your engine’s air intake
and severely damage your engine.
Once through the water, always dry the brakes by moving your vehicle
slowly while applying light pressure on the brake pedal. Wet brakes do
not stop the vehicle as quickly as dry brakes.Driving through deep
water where the transmission vent tube is submerged may allow
water into the transmission and cause internal transmission
damage.

2nd unit bodies are not included in maximum trailer weight ratings. The
weight of the additional“body”must be subtracted from the maximum
trailer weight.
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 carefully prior to and after any towing operation. The
following trailer towing charts apply to vehicles equipped with gasoline
engines; for Diesel engines, refer to the6.0 Liter Power Stroke Direct
Injection Turbo Diesel Supplement.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
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.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.

Load equalizing hitch
When hooking up a trailer using a load equalizing hitch, always use the
following procedure:
1. Park the unloaded vehicle on a level surface. With the ignition on and
all doors closed, allow the vehicle to stand for several minutes so that it
can level.
2. Measure the height of a reference point on the front and rear bumpers
at the center of the vehicle.
3. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within 0–13 mm (0.5 in) of the reference
point. After proper adjustment, the rear bumper should be no higher
than in Step 2.
Note:Adjusting an equalizing hitch so the rear bumper of the vehicle is
higher than it was unloaded will defeat the function of the load
equalizing hitch and may cause unpredictable handling.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. 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 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.
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 your
trailer lamps conform to local and Federal regulations. See your dealer or
trailer rental agency for proper instructions and equipment for hooking
up trailer lamps.

6. Recheck the fluid level on the dipstick. Do not add fluid if the level is
between the arrows in the FULL COLD range.
7. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL COLD range. Be sure to put the
dipstick back in the reservoir.
BRAKE FLUID RESERVOIR
The fluid level will drop slowly as
the brakes wear, and will rise when
the brake components are replaced.
Fluid levels below the“MAX”line
that do not trigger the brake system
warning lamp are within the normal
operating range, there is no need to
add fluid. If the fluid levels are outside of the normal operating range,
the performance of your brake system could be compromised, seek
service from your dealer immediately.
CLUTCH FLUID (IF EQUIPPED)
Check the clutch fluid level. Refer to the scheduled maintenance guide
for the service interval schedules.
Use only a DOT 3 brake fluid designed to meet Ford specification
ESA-M6C25–A. Refer toLubricant Specificationsin this chapter.
Brake fluid is toxic. If brake fluid contacts the eyes, flush eyes
with running water for 15 minutes. Seek medical attention if
irritation persists. If taken internally, drink water and induce vomiting.
Seek medical attention immediately.
During normal operation, the fluid level in the clutch reservoir should
remain constant or rise slightly. If the fluid level drops, refill the fluid
level to the step in the reservoir.
