R (Reverse)
With the gearshift lever in R (Reverse), the
vehicle will move backward. Always come
to a complete stop before shifting into and
out of R (Reverse).
N (Neutral)
With the gearshift lever in N (Neutral), the
vehicle can be started and is free to roll.
Hold the brake pedal down while in this
position.
D (Overdrive) with tow/haul off
D (Overdrive) with tow/haul off is the
normal driving position for the best fuel
economy. The overdrive function allows
automatic upshifts and downshifts through
gears one through six.
D (Overdrive) with tow/haul on
The tow/haul feature improves
transmission operation when towing a
trailer or a heavy load. All transmission
gear ranges are available when using
tow/haul.
To activate tow/haul, press the
button on the end of the
gearshift lever. The TOW HAUL
indicator light will illuminate in the
instrument cluster. Tow/haul delays upshifts to reduce
frequency of transmission shifting.
Tow/haul also provides engine braking in
all forward gears when the transmission is
in the D (Overdrive) position; this engine
braking will slow the vehicle and assist the
driver in controlling the vehicle when
descending a grade. Depending on driving
conditions and load conditions, the
transmission may downshift, slow the
vehicle and control the vehicle speed when
descending a hill, without the accelerator
pedal being pressed. The amount of
downshift braking provided will vary based
upon the amount the brake pedal is
pressed.
Tow/haul may be automatically activated
(without pressing the tow/haul button).
This provides engine braking to assist the
vehicles braking system when going
downhill and repetitive braking is sensed.
Once the tow/haul mode has been
automatically activated it will not
automatically deactivate.
To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the end of the gearshift lever.
The TOW HAUL light will no longer be
illuminated.
Tow/haul will also deactivate when the
vehicle is powered down for a few minutes.
WARNING
Do not use the tow/haul feature
when driving in icy or slippery
conditions as the increased engine
braking can cause the rear wheels to slide
and the vehicle to swing around with the
possible loss of vehicle control. 142

By moving the gearshift lever from the D
(Drive) position to the M (Manual) position
you may now manually select the gear you
desire. Only the current gear will be
displayed. Press the + button or the –
button to upshift or downshift. If the –
button is pressed at a vehicle speed that
would cause an engine overspeed, the
requested gear will flash then disappear
and the transmission will remain in the
current gear.

In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift will still automatically
make some downshifts if it has determined
that you have not downshifted in time.
Although SelectShift will make some
downshifts for you, it will still allow you to
downshift at any time as long as the
SelectShift determines that the engine will
not be damaged from over-revving.
SelectShift will not automatically upshift,
even if the engine is approaching the RPM
limit. It must be shifted manually by
pressing the + button.
Note: Engine damage may occur if
excessive engine revving is held without
shifting. Automatic Transmission Adaptive
Learning
This feature is designed to increase
durability and provide consistent shift feel
over the life of the vehicle. A new vehicle
or transmission may have firm shifts, soft
shifts or both. This operation is considered
normal and will not affect function or
durability of the transmission. Over time,
the adaptive learning process will fully
update transmission operation.
Additionally, whenever the battery is
disconnected or a new battery installed,
the strategy must be relearned.
Brake-Shift Interlock
WARNINGS
Do not drive your vehicle until you
verify that the brake lamps are
working.
144
Super Duty (TFA) Transmission
WARNINGS
When doing this procedure, you will
be taking the vehicle out of park
which means the vehicle can roll
freely. To avoid unwanted vehicle
movement, always fully set the parking
brake prior to doing this procedure. Use
wheel chocks if appropriate. If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. See your authorized
dealer. Your vehicle is equipped with a brake-shift
interlock feature that prevents the
gearshift lever from being moved from P
(Park) when the ignition is in the 3 (on)
position and the brake pedal is not pressed.
If you cannot move the gearshift lever out
of P (Park) position with the ignition in the
4 (on) position and the brake pedal
pressed, a malfunction may have occurred.
It is possible that a fuse has blown or the
vehicle
’s brake lamps are not operating
properly. See Fuse Specification Chart
(page 214).
If the fuse is not blown and the brake
lamps are working properly, the following
procedure will allow you to move the
gearshift lever from P (Park):
1. Apply the parking brake. Turn the ignition key to 1 (off), then remove the
key.
2. Move the steering column to the full down and full rearward position
(toward the driver ’s seat).
3. Remove the gearshift lever boot. 4. Place fingers into hole where the
gearshift lever boot was removed from
and pull top half of 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 to clear the hazard
flasher button, then pull straight
rearward toward the driver ’s 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 full unlocked
position and remove the lower shroud
cover by pulling the lever handle
through the slot in the cover. 8.

USING FOUR-WHEEL DRIVE
WARNING
For important information regarding
safe operation of this type of vehicle,
See General Information (page
254). Note:
Do not use 4X4 mode on dry, hard
surfaced roads. Doing so will produce
excessive noise, increase tire wear and may
damage drive components. 4X4 mode is
only intended for consistently slippery or
loose surfaces.
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/from 4L (4X4
Low) for proper operation.
Manual Shift On Stop (MSOS)
4WD system
(If Equipped)
Note: Some vehicles may be equipped with
wheel ornaments that cover the 4x4 manual
hub lock. These ornaments must be
removed to access the manual hub locks.
Note: The vehicle should not be driven in
4X4 High or 4X4 Low modes with the hub
locks set to FREE as this condition may
damage driveline system components. The 4WD system is engaged or disengaged
by rotating the control for both front wheel
hub locks from the FREE or LOCK position,
then manually engaging or disengaging the
transfer case with the floor-mounted
shifter. For increased fuel economy in 2WD,
rotate both hub locks to the FREE position.
Electronic Shift-On-the-Fly
(ESOF) 4WD system
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/from 4L (4X4
Low) for proper system operation.
Note: Auto-manual hub locks can be
manually overridden 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

Shifting between system modes
Note:
Do not perform these operations if
the rear wheels are slipping.
Note: Some noise may be heard as the 4x4
system shifts or engages. This is normal. In
order to reduce engagement noise, it is
recommended that all shifts be performed
at speeds below 3 mph (5 km/h).
Note: The vehicle should not be driven in
4X4 High with the hub locks disengaged as
this condition may damage driveline system
components.
Engage the locking hubs by rotating the
hub lock control from FREE to LOCK, then
move the transfer case lever from 2H
(2WD) to 4H (4x4 High) at a stop or a
vehicle speed below 3 mph (5 km/h).
Move the transfer case lever from 4H (4x4
High) to 2H (2WD) at a stop or a vehicle
speed below 3 mph (5 km/h), then
disengage the locking hubs (optional) by
rotating the hub lock control from LOCK
to FREE.
For proper operation, make sure that both
indicator arrows on the hub are aligned,
and that both hubs are set to either FREE
or LOCK.
Shifting to/from 4L (4x4 Low)
1. Bring the vehicle to a stop or a speed below 3 mph (5 km/h).
2. Place the transmission in N (Neutral).
3. Move the transfer case shift lever through N (Neutral) directly to the
desired position.
4. If the transfer case does not, or only partially moves to the desired position,
perform a shift with the transmission
in N (Neutral) and the vehicle rolling at
a speed below 3 mph (5 km/h). 5.
If shifting to 2H (2WD) with the vehicle
at a complete stop, disengage the
locking hubs (optional) by rotating the
hub lock control from LOCK to FREE.
Using the N (Neutral) position WARNING
Do not leave the vehicle unattended
with the transfer case in the N
(Neutral) position. Always set the
parking brake fully and turn off the ignition
when leaving the vehicle. The transfer case neutral position overrides
the transmission and puts the vehicle in
neutral regardless of transmission gearshift
lever position. The vehicle can move
forward or backwards.
This position should only be used when
towing the vehicle.
149
Super Duty (TFA) Four-Wheel Drive (If Equipped)E163189
If SHIFT DELAYED PULL FORWARD is
displayed in the information display,
transfer case gear tooth blockage is
present. To alleviate this condition, place
the transmission in a forward gear, move
the vehicle forward approximately 5 feet
(1.5 meters), and shift the transmission
back to neutral to allow the transfer case
to complete the range shift.
How Your Vehicle Differs From
Other Vehicles WARNING
Vehicles with a higher center of
gravity such as utility and four-wheel
drive vehicles handle differently than
vehicles with a lower center of gravity.
Utility and four-wheel drive vehicles are
not designed for cornering at speeds as
high as passenger cars any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these
vehicles. Failure to drive cautiously could
result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and
death. Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
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 from the
outside. Do not grip the spokes. Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning.
Driving Off-Road With Truck and
Utility Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive 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 cause for concern.
Note: Your vehicle may be equipped with
a front air dam that can become damaged
(due to reduced ground clearance) when
taking your vehicle off-road. This air dam
can be taken off by removing two bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud
and rough terrain and have operating
characteristics that are somewhat
different from conventional vehicles, both
on and off the road.
Power is supplied to all four wheels
through a transfer case. On Four-wheel
drive vehicles, the transfer case allows you
to select 4WD when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found in the
Maintenance chapter. You should become
thoroughly familiar with this information
before you operate your vehicle.
151
Super Duty (TFA) Four-Wheel Drive
(If Equipped)
If your vehicle has anti-lock brakes, apply
the brakes steadily. Do not pump the
brakes.
Driving on Snow and Ice
WARNING
If you are driving in slippery
conditions that require tire chains or
cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end of
your vehicle slides while cornering, steer in
the direction of the slide until you regain
control of your vehicle. Note:
Excessive tire slippage can cause
transmission damage.
Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it will not stop any faster as
braking occurs at all four wheels. Do not
become overconfident as to road
conditions. Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Do not pump the brake
pedal. See Hints on Driving With
Anti-Lock Brakes (page 158).
If Your Vehicle Gets Stuck In Mud or
Snow WARNING
Do not spin the wheels at over 35
mph (56 km/h). The tires may fail
and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,
it may be rocked 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,
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute, damage to the transmission
and tires may occur or the engine may
overheat.
Parking WARNINGS
If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. See your authorized
dealer. Always set the parking brake fully
and make sure the gearshift is
latched in P (Park). Turn the ignition
to the off position and remove the key
whenever you leave your vehicle. 154
