1999 FORD F250 engine

Engine exhaust, some of its constituents, and certain vehicle
components contain or emit chemicals known to the State of
California to cause cancer, and birth defects or other reproductive
harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by
keeping all air inlet vents clear of
snow, leaves and other debris.

Using RABS
•In an emergency, applying full pressure may cause the front wheels to
lock.If the front brakes lock, the vehicle cannot be steered.Yo u
should apply the brakes with steadily increasing force, as if
“squeezing” the brakes. If you feel the front wheels begin to lock,
momentarily release the pedal and repeat the “squeeze” technique.
•We recommend that you familiarize yourself with how the RABS
performs. However, avoid unnecessary risks.
Anti-lock brake system (ABS) (if equipped)
On vehicles equipped with an anti-lock braking system (ABS), a noise
from the hydraulic pump motor and pulsation in the pedal may be
observed during ABS braking events. Pedal pulsation coupled with noise
while braking under panic conditions or on loose gravel, bumps, wet or
snowy roads is normal and indicates proper functioning of the vehicle’s
anti-lock brake system. The ABS performs a self-check at 17 km/h (10
mph) after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.
The ABS operates by detecting the
onset of wheel lockup during brake
applications and compensating for
this tendency. The wheels are
prevented from locking even when
the brakes are firmly applied. The
accompanying illustration depicts
the advantage of an ABS equipped
vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during
hard braking with loss of front braking traction.
ABS warning lamp
The
ABSwarning lamp in the instrument cluster momentarily illuminates
when the ignition is turned on and the engine is off. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.

Always set the parking brake fully and make sure that the
gearshift is securely latched in P (Park) (automatic
transmission) or in 1 (First) (manual transmission).
The parking brake is not recommended to stop a moving vehicle.
However, if the normal brakes fail, the parking brake can be used to stop
your vehicle in an emergency. Since the parking brake applies only the
rear brakes, the vehicle’s stopping distance will increase greatly and the
handling of your vehicle will be adversely affected.
Pull the release lever to release the
brake. Driving with the parking
brake on will cause the brakes to
wear out quickly and reduce fuel
economy.
STEERING YOUR VEHICLE
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to help steer the vehicle.
Never hold the steering wheel to the extreme right or the extreme left
position for more than a few seconds when the engine is running. This
action could damage the power steering pump.
If the amount of effort needed to steer your vehicle changes at a
constant vehicle speed, have the power steering system checked. If the
power steering system breaks down (or if the engine is turned off), you
can steer the vehicle manually, but it takes more effort.
After any severe impact such as striking large potholes, sliding into curbs
on icy roads or a collision involving the front end, have the front
suspension and steering checked for possible damage.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.

Extended use of other than the manufacturer’s specified size tires on a
Traction-Lok rear axle could result in a permanent reduction in
effectiveness. This loss of effectiveness does not affect normal driving
and should not be noticeable to the driver.
To avoid injury, never run the engine with one wheel off the
ground, such as when changing a tire.
TRANSMISSION OPERATION
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift from being moved from P (Park) unless the brake pedal is
depressed.
If you cannot move the gearshift out of P (Park) with the brake pedal
depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Insert the key and turn it to OFF. Apply the brake pedal and shift to N
(Neutral).
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift, it is
possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer toFuses and relaysin theRoadside
emergencieschapter.
Do not drive your vehicle until you verify that the brakelamps
are working.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting from forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle for more than a few minutes. The
transmission and tires may be damaged or the engine may
overheat.

N (Neutral)
With the gearshift in N (Neutral),
the vehicle can be started and is
free to roll. Hold the brake pedal
down while in this gear.
(Overdrive)
The normal driving position for the
best fuel economy. Transmission
operates in gears one through four.
(Overdrive) can be deactivated
by pressing the Transmission
Control Switch (TCS) on the end of
the gearshift lever.
The transmission control indicator
light (TCIL) (the word OFF) on the
end of the gearshift lever will
illuminate.
Drive– Not shown on the display. Activate by pressing the Transmission
Control Switch (TCS) on the end of the gearshift lever with the gearshift
in the
position. The TCIL (the word OFF) will illuminate on the
gearshift lever. Transmission operates in gears one through three.
(Drive) provides more engine braking than(Overdrive) and is
useful when:
•driving with a heavy load.
•towing a trailer up or down steep hills.
•additional engine downhill braking is desired. If towing a trailer, refer
toDriving while you towin theTrailer towingsection.
To return to
(Overdrive) mode, press the Transmission Control
Switch (TCS). The TCIL (the word OFF) will no longer be illuminated.
Each time the vehicle is started, the transmission will automatically
return to normal overdrive mode.
Every time the vehicle is shut off and restarted, you must press the
transmission control switch to cancel overdrive operation if driving in
overdrive is not desired.

2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.
1 (First)
Use 1 (Low) to provide maximum
engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
(Overdrive). Selecting 1 (Low)
at higher speeds causes the transmission to shift to a lower gear, and will
shift to 1 (Low) after vehicle decelerates to the proper speed.
MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Using the clutch
Vehicles equipped with a manual transmission have a starter interlock
that prevents cranking the engine unless the clutch pedal is fully
depressed.
When starting a vehicle with a manual transmission, you must:
1. Put gearshift in N (Neutral).
2. Hold down brake pedal.
3. Depress clutch pedal.

(START) to start the engine, let the
engine idle for a few seconds, then
shift into gear.
5. Release the brake pedal.
6. Release clutch slowly while
pressing down slowly on the
accelerator pedal.
•Do not drive with your foot resting on the clutch pedal and do not use
the clutch to hold your vehicle at a standstill while waiting on a hill.

POWER TAKE OFF (PTO) CAPABILITY (IF EQUIPPED)
Some vehicles with 6.8L and 7.3L engines are equipped with Power Take
Off (PTO) capability. These vehicles have a special transmission case,
internal components and calibration for PTO usage. If your vehicle is
equipped with a 7.3L Diesel engine, refer to the 7.3L Diesel Supplement
for information on the auxiliary powertrain control module (APCM) and
its operation.
The PTO can be used during mobile and stationary
continuous/intermittent applications.
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 Manual 3
(Overdrive position with Overdrive canceled), Manual 2, Manual 1.
Refer to the “Body Builder’s Layout Book” for recommended electrical
installation.
