2021 FORD F-350 lock

WARNING: Do not remove the fuel
pump nozzle from its fully inserted
position when refueling. WARNING: When refueling always
shut the engine off and never allow
sparks or open flames near the fuel tank
filler valve. Never smoke or use a cell
phone while refueling. Fuel vapor is
extremely hazardous under certain
conditions. Avoid inhaling excess fumes. WARNING: Stop refueling after the
fuel pump nozzle automatically shuts
off for the second time. Failure to follow
this will fill the expansion space in the
fuel tank and could lead to fuel
overflowing. WARNING: The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury.
Note: If you must replace the fuel filler cap,
replace it with a fuel filler cap designed for
your vehicle. The vehicle warranty may be
void for any damage to the fuel tank or fuel
system if you do not use the correct genuine
Ford or Motorcraft® fuel filler cap.
Fueling Tips
If air is allowed to enter the fuel system the
engine automatically purges any trapped
air. To purge the air sooner: prior to engine
start, prime the system by turning the key
to on for 30 seconds then to off. Repeat
this several times. The engine may run
rough and produce white smoke while air
is in the system. This is normal.
Use only clean, approved containers that
prevent the entry of dirt or water whenever
you store diesel fuel. Diesel fuel must not be stored in a
galvanized container. The fuel can dissolve
the zinc in the galvanized container. The
zinc then remains in the fuel. If you run the
contaminated fuel through the engine, the
zinc can deposit in the fuel injectors
causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
Your vehicle has a fuel fill pipe that is able
to accept fuel up to
20 gal (76 L) per
minute from a 1.2 in (30 mm)
fuel-dispensing nozzle. Pumping fuel at
greater flow rates may result in premature
nozzle shut-off or spit back.
Truck stops have pumps and nozzles
designed for larger, heavy-duty trucks.
When refueling at truck stops: if the nozzle
shuts off repeatedly when refueling, wait
5– 10 seconds; then use a slower rate of
flow, do not depress the nozzle trigger as
far.
Refueling
When fueling your vehicle do the following:
1. Fully open the fuel tank filler door and remove the fuel tank filler cap.
Carefully turn the filler cap
counterclockwise until it spins off.

• Allows transmission to select an
appropriate gear.
Understanding Your SelectShift
Automatic ™ TransmissionNote:
When pressing the button on the
gearshift lever, you can cycle through the
available drive modes. See Drive Control
(page 268).
Your vehicle has a SelectShift Automatic ™
transmission gearshift lever. The
SelectShift Automatic transmission gives
you the ability to change gears up or down
without a clutch. To prevent the engine from running at too
low an RPM, which may cause it to stall,
SelectShift still makes some downshifts
for you if it determines that you have not
downshifted in time. Although SelectShift
makes some downshifts for you, it still
allows you to downshift at any time if the
SelectShift determines that damage to
the engine cannot occur from over-revving.
SelectShift does not upshift, even if the
engine is approaching the RPM limit. Shift
it manually by pressing the + button.
Note:
Engine damage could occur if you
maintain excessive engine revving without
shifting.
The SelectShift Automatic transmission
feature has two modes:
• Progressive Range Selection.
• Manual (M).
Progressive Range Selection - PRS Progressive Range Selection gives you the
ability to lockout gears from the automatic
shifting range. This could provide you with
an improved driving experience, for
example, in slippery conditions or when
experiencing a steep slope.
With the gearshift lever in drive (D), press
the – button to active PRS. The instrument
cluster indicates the available and selected
gears.

Automatic Transmission Adaptive
Learning
This feature's design is to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm shifts, soft
shifts or both. This operation is normal and
does not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation. Additionally, whenever you
disconnect the battery or install a new
battery, the system must relearn the
strategy.
Neutral Idle with F350, F450, F550
and F600 Chassis Cab Vehicles
Your transmission could reduce the load
on the engine when the vehicle stops, and
the gear selector is in drive (D) to reduce
fuel consumption and emissions. The
transmission resumes operation when you
release the brake. This feature activates
when the transmission is sufficiently
warmed, and the vehicle is on a level slope.
Brake-Shift Interlock WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheels
chocks if appropriate. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible.
Note: Do not drive your vehicle until you
verify that the brake lamps are working.
Your vehicle comes with brake-shift
interlock that prevents the gearshift lever
from moving from park (P) when you
switch the ignition on but have not pressed
the brake pedal.
If you cannot move the gearshift lever out
of the park (P) position when the ignition
is on and the brake pedal pressed, a
malfunction could have occurred. It is
possible that a fuse has blown, or your
vehicle ’s brake lamps are not operating
properly. See
Fuse Specification Chart
(page 339).
If you do not have a blown fuse and the
brake lamps are working properly, the
following procedure allows you to move
the gearshift lever from park (P):
1. Apply the parking brake. Switch the ignition key to 1 - 0, then remove the
key.
2. Move the steering column to the full down and full rearward position,
toward the driver seat.
3. Remove the gearshift lever boot.

4. Place your fingers into the hole where
you removed the gearshift lever boot
and pull the top half of the shroud up
and forward to separate it from the
lower half of the shroud. There is a
hinge at the forward edge of the top
shroud. Roll the top half of the shroud
upward on the hinge point, then pull
straight rearward toward the driver
seat to remove.
5. Remove the top half of the shroud.
6. Remove the three fasteners under the column that secure the lower shroud
half to the column. 7. Pull the lock lever into the fully
unlocked position and remove the
lower shroud cover by pulling the lever
handle through the slot in the cover.
8. Apply the brake. Gently lift the override
disk and move the gearshift lever into
neutral (N). 9. Start your vehicle.
Perform steps 4 through 8 in reverse order
to get the shroud back together, making
sure to engage the hinge pivots between
the upper and lower halves of the shroud.
Keep slight pressure in the forward
direction as you rotate the halves together.
If Your Vehicle Gets Stuck in Mud
or Snow
If your vehicle is stuck in mud or snow, you
can rock it out by shifting between forward
and reverse gears, stopping between shifts
in a steady pattern. Press lightly on the
accelerator in each gear.
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission could occur.
Note: Do not rock your vehicle for more
than a minute or damage to the
transmission and tires could occur, or the
engine could overheat.

USING FOUR-WHEEL DRIVE
Note:
For important information regarding
the safe operation of this type of vehicle,
see General Information in the Wheels and
Tires chapter.
Note: Do not use 4H or 4L mode on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive components. 4X4 mode is
only intended for consistently slippery or
loose surfaces. Use of 4L mode on these
surfaces may produce some noise, such as
occasional clunks, but will not damage drive
components.
Note: If 4X4 low is selected while the
vehicle is moving above 3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L (4X4
Low) for proper operation.
Note: You can switch on and switch off the
electronic locking differential by pulling the
4WD control (4WD vehicles) or turning the
electronic locking differential control (2WD
vehicles). See

(If Equipped)
Note: If 4X4 Low is selected while the
vehicle is moving above
3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L (4X4
Low) for proper system operation.
Note: Auto-manual hub locks can be
manually locked by rotating the hub lock
control from AUTO to LOCK. For proper operation, make sure that each
hub is fully engaged and that both hub
locks are set to the same position (both
set to LOCK or both set to AUTO). To
engage LOCK, turn the hub locks
completely clockwise; to engage AUTO,
turn the hub locks completely
counterclockwise.
The ESOF 4WD system:
•
Provides 4x4 High engagement and
disengagement while the vehicle is
moving.
• Is operated by a rotary control located
on the instrument panel that allows
you select 4x2, 4x4 High or 4x4 Low
operation.
• Uses auto-manual hub locks that can
be engaged and disengaged
automatically based on the 4x4 mode
selected.
• Will increase fuel economy when used
in the hub lock's recommended AUTO
mode.
4WD Indicator Lights
Note: When a 4X4 system fault is present,
the system will typically remain in whichever
4X4 mode was selected prior to the fault
condition occurring. It will not default to 4X2
in all circumstances. When this warning is
displayed, have your vehicle serviced by an
authorized dealer.
