ECU FORD F350 1999 Owners Manual

What you should do if the Service Engine Soon light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause yourService Engine Soonlight to
illuminate. Examples are:
1. The vehicle has run out of fuel. (The engine may misfire or run
poorly.)
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel and/or properly installing and securely tightening
the gas cap. After three driving cycles without these or any other
temporary malfunctions present, theService Engine Soonlight should
turn off. (A driving cycle consists of a cold engine startup followed by
mixed city/highway driving.) No additional vehicle service is required.
If theService Engine Soonlight remains on, have your vehicle serviced
at the first available opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.
Air bag readiness
Momentarily illuminates when the
ignition is turned ON. If the light
fails to illuminate, continues to flash
or remains on, have the system
serviced immediately.

1. Lift/rotate the seatback toward the rear of the vehicle and make sure
it latches securely.
2. Lift/rotate the lower seat cushion to its seating position.
SAFETY RESTRAINTS
Safety restraints precautions
Always drive and ride with your seatback upright and the lap
belt snug and low across the hips.
To reduce the risk of injury, make sure children sit where they
can be properly restrained.
Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag SRS is
provided.
It is extremely dangerous to ride in a cargo area, inside or
outside of a vehicle. In a collision, people riding in these areas
are more likely to be seriously injured or killed. Do not allow people to
ride in any area of your vehicle that is not equipped with seats and
safety belts. Be sure everyone in your vehicle is in a seat and using a
safety belt properly.
Each seating position in your vehicle has a specific safety belt
assembly which is made up of one buckle and one tongue that
are designed to be used as a pair. 1) Use the shoulder belt on the
outside shoulder only. Never wear the shoulder belt under the arm.
2) Never swing the safety belt around your neck over the inside
shoulder. 3) Never use a single belt for more than one person.

Always transport children 12 years old and under in the back
seat and always properly use appropriate child restraints.
Combination lap and shoulder belts
1. Insert the belt tongue into the
proper buckle (the buckle closest to
the direction the tongue is coming
from) until you hear a snap and feel
it latch. Make sure the tongue is
securely fastened in the buckle.
2. To unfasten, push the release
button and remove the tongue from
the buckle.
The front and rear outboard safety restraints in the vehicle are
combination lap and shoulder belts. The front passenger and rear seat
outboard safety belts have two types of locking modes described below:
Vehicle sensitive mode
The vehicle sensitive mode is the normal retractor mode, allowing free
shoulder belt length adjustment to your movements and locking in
response to vehicle movement. For example, if the driver brakes
suddenly or turns a corner sharply, or the vehicle receives an impact of
8 km/h (5 mph) or more, the combination safety belts will lock to help
reduce forward movement of the driver and passengers.
On SuperCab and CrewCab models, the front seat belt system can also
be made to lock manually by quickly pulling on the shoulder belt.
Rear seat belts (if equipped) cannot be made to lock up by pulling
quickly on the belt.

A belt-positioning booster should be used if the shoulder belt rests in
front of the child’s face or neck, or if the lap belt does not fit snugly on
both thighs, or if the thighs are too short to let the child sit all the way
back on the seat cushion when the lower legs hang over the edge of the
seat cushion. You may wish to discuss the special needs of your child
with your pediatrician.
SAFETY SEATS FOR CHILDREN
Child and infant or child safety seats
Use a safety seat that is recommended for the size and weight of the
child. Carefully follow all of the manufacturer’s instructions with the
safety seat you put in your vehicle. If you do not install and use the
safety seat properly, the child may be injured in a sudden stop or
collision.
When installing a child safety seat:
•Review and follow the information
presented in theAir Bag
Supplemental Restraint System
section in this chapter.
•Use the correct safety belt buckle
for that seating position.
•Insert the belt tongue into the
proper buckle until you hear a
snap and feel it latch. Make sure
the tongue is securely fastened in
the buckle.

5. To put the retractor in the
automatic locking mode, grasp the
shoulder portion of the belt and pull
downward until all of the belt is
extracted and a click is heard.
6. Allow the belt to retract. The belt will click as it retracts to indicate it
is in the automatic locking mode.
7. Pull the lap belt portion across
the child seat toward the buckle and
pull up on the shoulder belt while
pushing down with knee on the
child seat.
8. Allow the safety belt to retract to
remove any slack in the belt.
9. Before placing the child in the
seat, forcibly tilt the seat forward
and back to make sure the seat is
securely held in place.
10. Try to pull the belt out of the retractor to make sure the retractor is
in the automatic locking mode (you should not be able to pull more belt
out). If the retractor is not locked, unbuckle the belt and repeat steps
two through nine.
Check to make sure the child seat is properly secured before each use.

Attaching safety seats with tether straps
Some manufacturers make safety seats that include a tether strap that
goes over the back of the vehicle seat and attaches to an anchoring
point. Other manufacturers offer the tether strap as an accessory.
Contact the manufacturer of your child safety seat for information about
ordering a tether strap.
Tether anchorage hardware
A tethered seat can be installed in the front seat. Put the tether strap
over the seatback and attach it to an anchor bracket.
An anchor bracket can be installed to the inside of the back panel of
your vehicle.
The anchor bracket must be installed using the instructions provided
with the tether anchorage hardware kit.
Tether anchorage hardware kits (part number 613D74) including
instructions, may be obtained at no charge from any Ford or
Lincoln-Mercury dealer.
If you have a SuperCab or Crew Cab, Ford recommends you attach
tether safety seats in the rear seating position (if possible) with the
tether strap attached to the tether anchorage bracket as shown in the
instructions provided with the tether anchor kit.
Tighten the anchor according to specifications. Otherwise, the
safety seat may not be properly secured and the child may be
injured in a sudden stop or collision.

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.

Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn off the ignition whenever you leave
your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.

Driving with a 4–speed automatic transmission
Understanding gearshift positions
Pull the gearshift lever towards you and downward to move the
automatic gearshift.
Hold the brake pedal down while you move the gearshift lever
from P (Park) to another position. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and injure someone.
P (Park)
Always come to a complete stop
before shifting into P (Park). Make
sure the gearshift is securely latched
in P (Park). This position locks the
transmission and prevents the rear
wheels from turning.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn off the ignition whenever you leave
your vehicle.
R (Reverse)
With the gearshift in R (Reverse),
the vehicle will move backward.
Always come to a complete stop
before shifting into and out of R
(Reverse).
