To be sure your vehicle is ready to operate, conduct a pre-trip inspection
at the beginning of each work period. Follow the steps listed in this
section to assure a proper vehicle inspection procedure. The pages in
this section may be produced locally and used on a regular basis.
VEHICLE INSPECTION INFORMATION
Note:Always make sure the parking brake is applied before starting the
engine.
Engine compartment (with engine stopped)
Engine oil level:Use the engine oil dipstick to verify that the
engine oil level is between the FULL and ADD
marks.
Engine coolant
level:Look through the plastic reservoir or the clear
sight glass on the reservoir, depending upon
vehicle equipment, and make sure the fluid is
within the minimum and maximum fluid level
range as marked on the reservoir.Do not
remove pressure cap until the coolant has
cooled.
Power steering fluid:Verify that the fluid level is between the full
and refill marks.
Brake fluid (master
cylinder):Remove the master cylinder caps and inspect
the fluid level. The full mark is at the bottom
of the opening of the port ring.
Hydraulic clutch
fluid:Check for adequate amount of hydraulic clutch
fluid. Fluid level should be at the step of the
reservoir; refer toClutch fluid/linkage
adjustmentsin theMaintenance and
specificationschapter.
Belts (Fan,
alternator, water
pump and A/C
compressor):Check for glazing, fraying or cracking. There
should be no more than five - seven cracks per
rib per inch.
Any leaks:Check for signs of fluid puddles, dripping fluid
on the ground under the engine or the
underside of the engine.

Engine starting (parking brake applied)
Air brake check:Check the air brakes in the following manner
(Chock the wheels, if necessary. Push in the
parking brake and on tractors, also push in the
tractor parking brake knob):
1. Check the air compressor or governor cut-out
pressure (approximately 120 psi [827 kPa]).
2. Cut-off the engine and turn the key back to
ON, without starting the engine.
3. Without the brake pedal applied, note the
air pressure drop for one minute. It should be
less than 2 psi (14 kPa) for single vehicle and
3 psi (21 kPa) for combination vehicles.
4. Depress and hold the brake pedal with 90
psi (621 kPa) or more and make sure there is
no more than a 3 psi (21 kPa) per minute
leak. For combination vehicles, no more than 4
psi (28 kPa) per minute.
5. Pump the brake pedal to deplete the system
air pressure. The warning light and chime
should activate 57 psi (393 kPa).
6. Pump the brake pedal and make sure the
parking brake and trailer parking brake knobs
knobs pop out at 20 psi (138 kPa) or higher.
Parking brake:Check that the parking brake will hold the
vehicle by gently trying to pull forward with
the parking brake applied.
Automatic
transmission fluid:With the engine idling (at normal operating
temperature) and the parking brake applied,
check the automatic transmission fluid. If fluid
needs to be added, place the transmission in
the appropriate gear as specified in the
transmission operator’s manual and refer to
Transmission fluidin theMaintenance and
specificationschapter.

Range inhibit:Illuminates when
the transmission is not engaged in
the selected gear. The warning light
will go off when the gearshift lever
is adjusted in to the appropriate gear.
Refer to the Transmission Operator’s Manual for more information.
Charging system:Illuminates when
the battery is not charging properly.
Wait to start:Indicates the air
intake heater is in operation and
special starting procedures are
required. Refer to theDriving
chapter.
If equipped with an air intake heater, DO NOT use ether or any
other starting fluids. The use of starting fluids (ether) in an
engine equipped with an air intake heater could result in damage
and/or personal injury.
Water in fuel (if equipped):
During refueling it is possible for
water-contaminated diesel fuel to be
pumped into your fuel tank. Your
vehicle fuel system is equipped with
a fuel filter/water separator to remove water from the fuel. The indicator
light illuminates when the fuel filter/water separator has a significant
quantity of water, or when the ignition key is switched to the START
position. If the light illuminates when the engine is running, stop the
vehicle as soon as safely possible, shut off the engine and drain the filter
bowl. Allowing water to stay in the system could result in extensive
damage to, or failure of, the fuel injection system.
To drain the fuel filter/water separator (refer toMaintenance and
Specificationschapter for procedure), rotate the valve at the bottom of
the filter assembly allowing water to drain from the system. Close the
valve upon completion.

the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
Do not use extensions to change the fit of the shoulder belt
across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front seat belt buckle
assemblies, buckle support assemblies (slide bar-if equipped), shoulder
belt height adjusters (if equipped), shoulder belt guide on seatback (if
equipped), child safety seat tether anchors, and attaching hardware,
should be inspected after a collision.
Ford Motor Company recommends that all safety belt assemblies
used in vehicles involved in a collision be inspected for proper
function and replaced, if necessary. Safety belt assemblies not in use
during a collision should also be inspected and replaced if either
damage or improper operation is noted.
Failure to inspect and if necessary replace the safety belt
assembly under the above conditions could result in severe
personal injuries in the event of a collision.
Refer toInteriorin theCleaningchapter.
SAFETY RESTRAINTS FOR CHILDREN
Important child restraint precautions
You are required by law to use safety restraints for children in the U.S.
and Canada. If small children (generally children who are four years old
or younger and who weigh 40 lbs. [18 kg] or less) ride in your vehicle,
you must put them in safety seats made especially for children. Many
states require that children use approved booster seats until they are
eight years old. Check your local and state or provincial laws for specific
requirements regarding the safety of children in your vehicle. When
possible, always place children under age 12 in the rear seat of your
vehicle. Accident statistics suggest that children are safer when properly
restrained in the rear seating positions than in the front seating position.

After the engine starts:
•On some engines, the WAIT TO
START light should illuminate
after the engine starts. Allow the
engine to idle about three
minutes or until the engine
coolant temperature gauge begins to rise. Maintain idle speed until the
WAIT TO START light cycles off to indicate the air intake heater has
shut off (approximately six minutes). Operating the engine at higher
speeds will reduce the effectiveness of the air inlet heater.
•Do not increase engine speed
until the oil pressure gauge
indicates normal pressure.
•Ensure engine oil pressure is
indicated on the gauge within 15
seconds after starting.
•Idle the engine for three to five
minutes before operating with a
full load.
•Try to limit engine idle to 10 minutes. Excessive idling reduces fuel
economy.
•When starting a cold engine, increase the engine speed (RPM) slowly
to make sure adequate lubrication is available to the bearings.
Restarting after running out of fuel
The fuel system may need to be purged of air, refer toRunning out of
fuelin theMaintenance and specificationschapter.
Cold weather operation
Do not use volatile starting aids such as ether, propane or
gasoline in the engine air intake system. Glow plugs may ignite
vapors which can cause engine damage or personal injury.
In order to operate the engine in temperatures of 32°F(0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they’re in
optimum condition.
•Use a permanent-type engine coolant solution to protect the engine
against damage from freezing.

HYDRAULIC BRAKES (IF EQUIPPED)
Your service brakes are self-adjusting. Refer to theGeneral
Maintenance Informationfor scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle’s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a“metal-to-metal,”“continuous grinding”or
“continuous squeal”sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Note:Normally, choose the same gear to descend the hill that you would
use to ascend the hill.
IF BRAKES DO NOT GRIP WELL
•If you have been driving through deep water, gently apply the brakes
several times while the vehicle is moving slowly.
•Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high speed stops.
•Check brake adjustment.
•Check brake linings for excessive wear.
Hydraulic brake booster system (Hydromax)
The Hydromax systems receive fluid pressure from the power steering
pump to provide power assist during braking.
The Hydromax booster receives backup pressure from the reserve
system electric pump whenever the fluid in the power steering system is
not flowing. When the engine is OFF, the pump will turn on if the brake
pedal is applied, or if the ignition is turned to the ON position.
The sound of the pump operating may be heard by the driver, but this is
a normal characteristic of the system.

Cam brakes - automatic slack adjusters
Standard air brakes (cam) are
equipped with automatic brake
adjusters. Automatic adjustment
occurs during brake applications.
Inspect brakes for proper
adjustment at the intervals listed in
the vehicle Service Maintenance
Guide.
Emergency air brake
All vehicles are equipped with a dual brake system. In the unlikely event
of a failure of one system, the second system will function for emergency
stopping. These systems are all controlled by the brake pedal in the
same manner as for normal stops.
Do not continue to operate the vehicle with a failure of one of
the systems. Take the vehicle to your dealer for service
immediately.
Parking brake
Do not use the gearshift selector in place of the parking brake;
unexpected and possible sudden vehicle movement may occur if
these precautions are not taken. Always set the parking brake fully
AND make sure the gearshift selector is in R (Reverse) for vehicles
equipped with manual transmission, N (Neutral) for vehicles with
automatic transmission (except Allison 2400 transmission) or P (Park)
(Allison 2400 transmission).
If the service brakes should fail to operate while the vehicle is in motion,
you can make an emergency stop with the parking brake. Since the
parking brake only applies stopping power to the rear wheels, the
vehicle’s stopping distance will greatly increase and the handling of the
