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
Electronic Locking
Differential (page 219).
Manual Shift On Stop (MSOS)
4WD system
(If Equipped)
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
(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 overridden by rotating the hub lock
control from AUTO to LOCK. 210

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.
4X2 Momentarily illuminates when
2H is selected.
4X4 HIGH Continuously illuminates when
4H is selected. 4X4 LOW Continuously illuminates when
4L is selected.
CHECK 4X4 Displays when a 4X4 fault is
present.
Using a Manual Shift On Stop
(MSOS) 4WD system (If Equipped)
Note: High shift efforts may be encountered
when attempting to shift into and out of 4x4
modes. It is recommended to allow the
vehicle to roll at a speed below
3 mph
(5 km/h) when shifting between modes. 2H (4X2)
For general on-road driving. Sends power
to the rear wheels only and should be used
for street and highway driving. Provides

Note:
Exceeding this limitation
may significantly reduce the
performance of your towing
vehicle. Selecting a trailer with a
low aerodynamic drag and rounded
front design helps optimize
performance and fuel economy.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per 1000 feet (300 meters)
starting at the 1000 foot (300
meter) elevation point. Note:
Certain states require
electric trailer brakes for trailers
over a specified weight. Be sure to
check state regulations for this
specified weight. The maximum
trailer weights listed may be limited
to this specified weight, as your
vehicle's electrical system may not
include the wiring connector
needed to use electric trailer
brakes.
Your vehicle may tow a trailer
provided the maximum trailer
weight is less than or equal to the
maximum trailer weight
calculated using the formula

The active guidelines fade in and out
depending on the steering wheel position.
The active guidelines are not shown when
the steering wheel position is straight.
Always use caution while reversing.
Objects in the red zone are closest to your
vehicle and objects in the green zone are
farther away. Objects are getting closer to
your vehicle as they move from the green
zone to the yellow or red zones. Use the
side view mirrors and rear view mirror to
get better coverage on both sides and rear
of your vehicle.
Refer to the Rear View Camera section for
additional information. See Rear View
Camera (page 232).
Hitches
Note: On pick-up trucks, the trailer hitch
provided on this vehicle enhances crash
protection for the fuel system. Do not
remove!
Note: Do not cut, drill, weld or modify trailer
hitches. Modifying trailer hitches can reduce
hitch rating.
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% for conventional towing or
15-25% for fifth wheel towing of the total
weight of the trailer is on the tongue.
Hitch components (If Equipped)
The following components will be included
in certain vehicles.
• A 5/8 inch hitch pin rated to tow up to
21,000 lbs.
• A 3 inch drawbar.
• A hitch pin sleeve to be used when
mounting the 3 inch drawbar.
• A clevis pin to help keep the hitch pin
in place. Weight-distributing Hitches WARNING
Do not adjust the spring bars so that
your vehicle's rear bumper is higher
than before attaching the trailer.
Doing so will defeat the function of the
weight-distributing hitch, which may cause
unpredictable handling, and could result
in serious personal injury. When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park the loaded vehicle, without the
trailer, on a level surface.
2. Measure the height to the top of your vehicle's front wheel opening on the
fender. This is H1.
3. Attach the loaded trailer to your vehicle
without the weight-distributing bars
connected.
4. Measure the height to the top of your vehicle's front wheel opening on the
fender a second time. This is H2.
5. Install and adjust the tension in the weight-distributing bars so that the
height of your vehicle's front wheel
opening on the fender is approximately
halfway between H1 and H2.
6. Check that the trailer is level or slightly
nose down toward your vehicle. If not,
adjust the ball height accordingly and
repeat Steps 2-6.

When Towing a Trailer
•
Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position P to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• If your vehicle is equipped with
Adaptive Steering and you have
enabled Tow/Haul, the Adaptive
Steering system adjusts the steering
response to match your vehicle ’s load.
The system reduces vehicle sensitivity
to steering inputs at higher vehicle
speeds while it maintains the ease of
parking and maneuverability at low
speeds. •
If your vehicle is equipped with
AdvanceTrac with RSC, this system
may turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed while towing may reduce
this tendency.
• If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant (if the axle is not already
filled with it).
• 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 automatic transmission in position
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.

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least
1,000 mi
(1,600 km) before towing a trailer. Make
sure you use the specified engine oil. See
Capacities and Specifications
(page
418).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
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.
290
Super Duty (TFE) Canada/United States of America, enUSA, First Printing Driving Hints

•
Fuel economy may decrease with lower
temperatures during the first 8– 10
miles (12 –16 kilometers) 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.
• Close the windows for high-speed
driving.
DRIVING THROUGH WATER WARNING
Do not drive through flowing or deep
water as you may lose control of your
vehicle.
Note:
Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
FLOOR MATS WARNINGS
Always use floor mats that are
designed to fit the foot well of your
vehicle. Only use floor mats that
leave the pedal area unobstructed. Only
use floor mats that are firmly secured to
retention posts so that they cannot slip out
of position and interfere with the pedals
or impair safe operation of your vehicle in
other ways. Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal
injury. Always make sure that the floor
mats are properly attached to the
retention posts in the carpet that are
supplied with your vehicle. Floor mats must
be properly secured to both retention posts
to make sure mats do not shift out of
position. Never place floor mats or any other
covering in the vehicle foot well that
cannot be properly secured to
prevent them from moving and interfering
with the pedals or the ability to control the
vehicle.
