•
Electronic stability control and traction
control maintains your vehicle control
in adverse conditions or
high-performance driving.
• Electronic throttle control enhances
the powertrain response to your inputs.
• Transmission controls are optimized
with shift schedules tuned to each
terrain.
Using the System
The system tailors your vehicle
configuration for each mode you select.
Column Shifter To change the drive mode setting, press
the drive mode button. The drive mode
selection menu appears in the instrument
cluster and allows you to select through
the available drive modes.
Normal – For everyday driving.
This mode is a perfect balance
of excitement, comfort, and
convenience. WARNING: Do not use tow/haul
when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle. Tow/Haul – For improved
transmission operation when
towing a trailer or a heavy load.
This mode moves upshifts to higher engine
speeds to reduce the frequency of
transmission shifting. This mode also
provides engine braking in all forward
gears, which slows your vehicle and assists
you in controlling your vehicle when
descending a grade. The amount of
downshift braking provided varies based
on the amount you press the brake pedal. Deep Snow/Sand – For snow or
soft, dry sand.
Eco – For efficient driving. This
mode helps deliver maximum
fuel efficiency and helps to
increase driving range. Slippery – For less than ideal
road conditions such as snow or
ice covered roads. Use this mode
for crossing terrain where loose, wet or
slippery material covers a firm surface.
Slippery mode lowers throttle response
and, if equipped with automatic
transmission, optimizes shifting for slippery
surfaces. Rock Crawl – For optimum
rock-climbing ability. Rock crawl
mode prompts you to put your
vehicle in 4x4 Low. Rock Crawl mode
optimizes the throttle and transmission
response to provide you additional control
of your vehicle. See
Using Four-Wheel
Drive (page 213). Some drive modes reduce
traction and stability control
performance and the warning
indicator illuminates in the instrument
cluster.

Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Your vehicle may be equipped with a
temporary or conventional spare tire. A
"temporary" spare tire is different in size
(diameter or width), tread-type
(All-Season or All Terrain) or is from a
different manufacturer than the road tires
on your vehicle. Consult information on the
tire label or Safety Compliance label for
limitations when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
you remove the trailer from the water.
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.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability. Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS
WARNING:
If your vehicle has a
steering wheel lock make sure the
ignition is in the accessory or on position
when being towed.
Emergency Towing
If your vehicle becomes inoperable
(without access to wheel dollies,
car-hauling trailer, or flatbed transport
vehicle), it can be flat-towed (all wheels
on the ground, regardless of the powertrain
and transmission configuration) under the
following conditions:
• Your vehicle is facing forward for
towing in a forward direction.
• Place the transmission in neutral (N).
If you cannot move the transmission
into neutral (N), you may need to
override it. See
Transmission (page
207).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).
Recreational Towing
Note: Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering your vehicle.
See
Climate Control (page 143).
314
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Towing

Follow these guidelines if you have a need
for recreational towing, such as towing
your vehicle behind a motorhome. We have
designed these guidelines to prevent
damage to your transmission.
Two-wheel Drive Vehicles
Do not tow your vehicle with any wheels
on the ground, as vehicle or transmission
damage may occur. You must tow your
vehicle with all four (4) wheels off the
ground, such as when using a car-hauling
trailer.
Four-wheel Drive Vehicles
If towing your vehicle with wheels off the
ground it must be all four wheels, such as
when using a car-hauling trailer.
To tow a four-wheel drive vehicle with all
wheels on the ground, place the transfer
case in its neutral position and engage the
four-wheel-down towing feature.
Perform the steps in the following section
after positioning your vehicle behind the
tow vehicle and properly securing them
together.
Note:
Make sure you properly secure your
vehicle to the tow vehicle.
Towing With All Four Wheels On The
Ground
1. Put the ignition in the on position, but do not start the engine.
2. Press and hold the brake pedal.
3. Rotate the four-wheel drive control to 2H.

Note: You do not need to leave your keys
in the vehicle. You can lock and unlock your
vehicle as you normally do.
14. Release the brake pedal. WARNING:
Do not disconnect the
battery during recreational towing. It
prevents the transfer case from shifting
properly and may cause the vehicle to
roll, even if the transmission is in park
(P). WARNING:
Shifting the transfer
case to its neutral position for
recreational towing may cause the
vehicle to roll, even if the transmission is
in park (P). It may injure the driver and
others. Make sure you press the foot
brake and the vehicle is in a secure, safe
position when you shift to neutral (N).
Note: Failing to put the transfer case in its

ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before turning it off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving. •
Drive a heavily loaded vehicle or tow a
trailer.
• Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).
• Driving with the wheels out of
alignment.
Conditions
• Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
• To maximize the fuel economy, drive
with the tonneau cover installed (if
equipped).
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 5–10 mi
(12 –16 km) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
• Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.
OFF-ROAD DRIVING
Note: The following off-road driving
information applies to Tremor package
equipped vehicles only.
