manual transmission FORD F250 SUPER DUTY 1999 Owners Manual

2. Make sure the headlamps and vehicle accessories are off.
If starting a vehicle with an automatic transmission:
•Make sure the parking brake is
set.
•Make sure the gearshift is in P (Park).
If starting a vehicle with a manual transmission:
•Make sure the parking brake is set.
•Push the clutch pedal to the
floor.
3. Turn the key to 4 (ON) without
turning the key to 5 (START).

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.

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.

Removing key from ignition
•Turn the ignition key until it
stops.
•Push the release lever forward
and rotate the key towards you
and remove.
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.

Shifting from 2H (2WD high) to 4H (4WD high)
Engage the locking hubs by rotating
the hub lock control from FREE to
LOCK, then move the transfer case
lever from 2H (2WD High) to 4H
(4WD High).
Do not shift into 4H (4WD High)
with the rear wheels slipping.
Shifting from 4H (4WD high) to 2H (2WD high)
Move the transfer case lever to 2H
(2WD High) at a stop or any
forward speed up to 88 km/h (55
mph).
With the vehicle at complete stop,
disengage the locking hubs
(optional) by rotating the hub lock
control from LOCK to FREE.
Shifting from 4H (4WD high) to 4L (4WD low)
1. Bring the vehicle to a complete stop.
2. Depress the brake.
3. Place the gearshift lever in N (Neutral) (automatic transmission) or
depress the clutch (manual transmission).

Shifting from 2WD (2WD high) to 4x4 HIGH (4WD high)
Rotate the 4WD control to the 4x4
HIGH position at speeds up to 88
km/h (55 mph).
•Do not shift into 4x4 HIGH with
the rear wheels slipping.
Shifting from 4x4 HIGH (4WD high) to 2WD (2WD high)
Rotate the 4WD control to 2WD at
any forward speed. You do not need
to put the gearshift in R (Reverse)
to disengage your front hubs.
To prevent damage, the electronic
shift 4WD system is designed to
allow up to 45 seconds before the
shift command is performed. In the
event that conflicting shift
commands are selected, allow up to
45 seconds for the shift command to
be performed prior to reporting any shift concerns to your dealer.
Shifting between 4x4 HIGH (4WD high) and 4x4 LOW (4WD low)
1. Bring the vehicle to a complete stop.
2. Depress the brake.
3. Place the gearshift in N (Neutral) (automatic transmission) or depress
the clutch (manual transmission).

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.
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.
Using a step bumper
The rear bumper is equipped with an integral hitch and requires only a
ball with a 25.4 mm (one inch) shank diameter. The bumper hasa2270
kg (5 000 lb.) trailer weight and 227 kg (500 lb.) tongue weight
capability.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
Do not drive faster than 88 km/h (55 mph) when towing a trailer.
Speed control may shut off if you are towing on long, steep grades.
When towing a trailer:
•Use a lower gear when towing up or down steep hills. This will
eliminate excessive downshifting and upshifting for optimum fuel
economy and transmission cooling.
•Anticipate stops and brake gradually.
Exceeding the GCWR rating may cause internal transmission
damage and void your warranty coverage.

Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your Scheduled Maintenance guide
for more information.
Trailer towing tips
•Practice turning, stopping and backing up in an area before starting on
a trip to get the feel of the vehicle trailer combination. When turning,
make wider turns so the trailer wheels will clear curbs and other
obstacles.
•Allow more distance for stopping with a trailer attached.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) (automatic transmissions) or N (Neutral)
(manual transmissions). This aids engine cooling and air conditioner
efficiency.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
•Do not allow the static water level to rise above the bottom edge of
the rear bumper and
•Do not allow waves to break higher than 15 cm (six inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
Replace front and rear axle lubricants anytime the axles have been
submerged in water. Axle lubricant quantities are not to be checked
unless a leak is suspected.
Recreational towing
If you may want to tow your vehicle behind another vehicle, such as an
RV, follow these guidelines:
