[DR17960(B F )06/94]
Ð The initial shift from two-wheel drive to 4x4
while the vehicle is moving can cause some
momentary clunk and ratcheting sounds. This is
the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not a
cause for concern.
*
[DR17990(B F )12/91]
Ð Because of possible damage to powertrain
components, never shift from Two-Wheel Drive
to 4x4 with the rear wheels slipping.
*
[DR18020(B F )06/94]
To shift from 4x4 to Two-Wheel Drive:
*
[DR18050(B F )06/94]
Push the 4x4 button; the 4x4 lamp on the
instrument cluster will go out indicating the
vehicle is in Two-Wheel Drive. This can be done
at any speed. To disengage the automatic
locking hubs, operate the vehicle in Two-Wheel
Drive in the opposite direction for approximately
10 feet (3 meters) in a straight line.
*
[DR18080(B F )06/94]
For example:
*
[DR18110(B F )06/94]
If you were driving the vehicle forward in
4x4, the automatic locking hubs will
disengage the next time the vehicle is driven
in reverse in Two-Wheel Drive for
approximately 10 feet (3 meters) in a straight
line.
*
[DR18140(B F )06/94]
If you were driving the vehicle in reverse in
4x4, the automatic locking hubs will
disengage the next time the vehicle is driven
forward in Two-Wheel Drive for
approximately 10 feet (3 meters) in a straight
line.
*
[DR18170(B F )01/95]
Operating in two-wheel drive mode with the
hubs locked increases fuel consumption, noise,
vibration, and wear. For prolonged two-wheel
drive operation on dry pavement, disengagement
of the automatic locking hubs, which is not
required for two-wheel drive operation, stops all

Manual locking hubs must be in LOCK
position before shifting into four-wheel drive.
*
[DR19800(B F )11/89]
When using four-wheel drive, maintain steering
wheel control at all times, especially in rough
terrain. Since sudden changes in terrain can
result in abrupt steering wheel motion, make
sure you grip the steering wheel rim from the
outside. Do not grip the spokes.
*
[DR19900(B F )05/90]
Drive cautiously to avoid vehicle damage from
concealed objects such as rocks and stumps.
Know the terrain or examine maps of the area in
question before driving. Map out your route
beforehand. To maintain steering and braking
control of your vehicle, you must have all four
tires on the ground, and they must be rolling,
not sliding or spinning.
*
[DR19925(B F )11/89]
Transmission upshift in 4x4 with transfer case in
4L may be quite firm due to large total gear
reduction. This condition is normal.
*
[DR20000(B F )11/89]
Sand
*
[DR20100(B F )11/89]
When driving over sand, try to keep all four
wheels of the vehicle on the most solid area of
the trail. Do not reduce the tire pressures but
shift to a lower gear and drive steadily through
the terrain. Apply accelerator slowly and avoid
spinning the wheels.
*
[DR20200(B F )11/89]
Mud and Water
*
[DR20300(B F )12/89]
When driving through water, determine the
depth; avoid water higher than the bottom of
the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
*
[DR20400(B F )11/89]
Once through water, always try the brakes. Wet
brakes do not stop the vehicle as effectively as
dry brakes. Drying can be improved by moving
your vehicle slowly, while applying light
pressure on the brake pedal.

Rear Anti-lock Brakes
*
[DR22600( F )02/92]
Except for F-Super Duty and F-Series
Commercial and Motorhome Stripped Chassis,
F-Series Light Trucks are equipped with a Rear
Antilock Brake System. This system prevents at
least one and often both rear wheels from
locking up when the brakes are applied in a
panic stop, for example.
*
[DR22800( EF )07/94]
Even with the Anti-lock Brake System, you
should be careful when braking. Front brake
lock up on any surface, even on smooth
pavement causes loss of steering control. Heavy
braking on roads with loose surfaces such as
snow or gravel, or severe pavement irregularities
could also cause you to lose steering control of
your vehicle.
*
[DR22900( EF )05/95]
RWARNING
If the anti-lock brake system warning
light remains on or comes on while
driving, have the braking system checked
by a qualified service technician as soon
as possible.
*
[DR22902( EF )05/95]
NOTE: If a fault occurs in the anti-lock
system, and the brake warning light is
not lit, the anti-lock system is disabled
but normal brake function remains
operational.
*
[DR23100( F )11/89]
If Brakes Do Not Grip Well or Pedal is
ªLowº (F-150/350 Only)
*
[DR23200(BEF )11/89]
If brakes do not grip well, it may indicate the
rear drum brakes need adjustment. To do this,
drive the vehicle in reverse at 5 mph (8 km/h)
on level, dry pavement. Stop the vehicle by
firmly applying the brakes. Repeat this
procedure four or five times.

Parking Brake
*
[DR24950(B F )03/95]
RWARNING
When parking, do not use the gearshift in
place of the parking brake. Turn the key
to LOCK whenever you leave your
vehicle. 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). Never leave your vehicle
unattended while it is running. If you do
not take these precautions, your vehicle
may move unexpectedly and injure
someone.
[DR24970(B F )05/95]
When the transfer case is in the N (Neutral)
position, the engine and transmission are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if the
automatic transmission is in P (Park) or the
manual transmission is in gear.

[DR27350(B F )06/94]
RWARNING
The rear antilock brake system may not
prevent brake lock-up on extremely
slippery surfaces. Rear brake lock-up may
also occur while driving in four-wheel
drive because the transfer case couples the
front and rear axles together.
*
[DR27450(BEF )03/95]
Traction-Lok Rear Axle (If equipped)
*
[DR27501(BEF )03/95]
This axle provides added drive away traction on
slippery surfaces, particularly when one or more
wheels are on a surface with poor traction.
*
[DR27550(BEF )03/93]
Extended use of other than matching 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.
*
[DR27601(BEF )05/95]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.

High water
*
[DR27675( ALL)06/92]
Never attempt to cross water that is fast flowing
or of unknown depth.
*
[DR27701( ALL)05/90]
Do not drive through flooded areas unless you
are sure that the water is below the bottom of
the wheel hubs.
*
[DR27750( ALL)04/94]
If you must drive through high water, drive
slowly. You may have limited traction or wet
brakes, so allow extra stopping distance because
your vehicle will not stop as quickly as usual.

Vehicle Loading/Towing
Information
*
[DR29450(BEF )03/91]
Your vehicle's load capacity is designated by
weight, not volume, so you cannot necessarily
use all available space with large or heavy loads.
Maximum safe vehicle weights as well as tire,
rim sizes and inflation pressures are specified for
your vehicle at the assembly plant on the Safety
Compliance Certification Label. The Certification
Label is located on the left front door lock facing
or the door latch post pillar.
*
[DR29501( ALL)12/91]
Trucks, unlike passenger cars, are basically
custom vehicles designed to carry a load. Most
owners start with a base vehicle and add
production and dealer installed and/or
aftermarket components to suit their tastes and
purposes. Even trucks that are purchased for
personal transportation only are likely to have
considerable optional equipment, such as step
bumpers and light bars, for example.
*
[DR29525( ALL)05/95]
RWARNING
Passengers should not be allowed to ride
in the cargo area. Persons not riding in a
seat with a fastened seat belt are much
more likely to suffer serious injury in a
collision. Cargo should always be secured
to prevent it from shifting and causing
damage to the vehicle or harm to
passengers.
*
[DR29551( ALL)03/91]
Each additional item of equipment affects how
much cargo a vehicle can carry. If a vehicle is
overloaded, performance will suffer and service
concerns may arise.

When the truck is ordered with a spare wheel
only (no tire), it is stowed with a wood spacer
in the usual spare tire location. Remove the
wood spacer before installing the spare tire and
wheel.
*

After the spare tire and wheel are stowed, adjust
the driver side channel ball end bolt and the
eyebolt as necessary until the tire cannot be
moved by hand pressure.

Preparing to Change the Tire
*
[RE15250( ALL)12/91]
NOTE: To lift your vehicle by other than the
front or rear jacking points, be sure to
use only hoist adapters with a wide
contact surface.

1. Make sure that your vehicle will not move
or roll. If you have an automatic
transmission, put the gearshift in Park. If
you have a manual transmission, put the
gearshift in Reverse. Set the parking brake
and block the wheel that is diagonally
opposite the tire that you are changing.

[RE15375(B F )05/95]
When one of the back wheels is off the ground,
the transmission alone will not prevent the
vehicle from moving or slipping off the jack,
even if the vehicle is in P (Park) or 1 (First). To
prevent the vehicle from moving when you
change a tire, be sure the parking brake is set,
then block the wheel (both directions) that is
diagonally opposite (other side and end of the
vehicle) to the tire that is being changed.
