2005 FORD SUPER DUTY Owners Manual

If your vehicle sustains damage to the rear bumper/fascia, leaving
it misaligned or bent, the sensing zone may be altered causing
inaccurate measurement of obstacles or false alarms.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
For important information regarding safe operation of this type
of vehicle, seePreparing to drive your vehiclein this chapter.
When four–wheel drive (4WD) is engaged, power is supplied to all four
wheels through a transfer case. 4WD can be selected when additional
driving power is desired.
4WD operation is not recommended on dry pavement. Doing so could
result in difficult disengagement of the transfer case, increased tire wear
and decreased fuel economy.
Manual 4x4 system (if equipped)
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.
•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 FREE). To engage LOCK,
turn the hub locks completely clockwise; to disengage the hubs
(FREE), turn the hub locks completely counterclockwise.
•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.
Electronic shift on the fly (ESOF) 4x4 system (if equipped)
If equipped with the electronic shift 4WD System, and the
instrument panel control is moved to 4X4 LOW (4WD Low) while
the vehicle is moving above 3 mph (5 km/h), the system will not
engage and no damage will occur to the 4WD system. Before 4X4

LOW (4WD Low) can be engaged, the vehicle speed must be
below 3 mph (5 km/h) with the brake pedal depressed and the
transmission in N (Neutral). This vehicle is equipped with a
non-synchronous low range gearset which will not allow the
transfer case to shift into 4X4 LOW (4WD Low) if vehicle speed
is above 3 mph (5 km/h). It is recommended that a shift to 4X4
LOW (4WD Low) is performed while the vehicle speed is below 3
mph (5 km/h).
The 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 2WD, 4x4 High or 4x4 Low operation.
•uses auto-manual hub locks that can be engaged and disengaged
automatically based on the 4x4 mode selected.
•auto-manual hub locks can be
manually overridden by rotating
the hub lock control from AUTO
to LOCK if desired.
•automatic operation of the
hub locks is recommended,and
will increase fuel economy
•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.
4WD system indicator lights
The 4WD system indicator lights illuminate only under the following
conditions. If these lights illuminate when driving in 2WD, contact your
Ford dealer as soon as possible.
•4x4- momentarily illuminates
after the engine is started.

Using the N (Neutral) position
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.
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.

seconds before a shift command is performed. In the event that
conflicting shift commands are selected, allow up to 45 seconds
for the shift command to be performed prior to reporting any
shift concerns to your dealer.

•The electronic shift 4WD
system is designed to engage
4x4 HIGH (4WD High) when
the vehicle is moving. If

4x4 may not engage and the
4x4 indicator may not

Shifting from 4x4 HIGH (4WD High) to 2WD (2WD High)
Rotate the 4WD control to 2WD at
any forward speed. Disengagement
of the transfer case and front hubs
may be delayed due to torque bind
which is caused by driving on dry
hard surfaces or performing tight
turns while using the 4WD system.
•Yo udo notneed to operate the vehicle in R (Reverse) to disengage
your front hubs, but it will eliminate any torque bind and allow the
system to immediately disengage.

Driving off-road with truck and utility vehicles
4WD 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.
How your vehicle differs from other vehicles
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.
Basic operating principles
•Do not use 4WD on dry, hard surfaced roads. Doing so will produce
excessive noise, increase tire wear and may damage drive components.
4WD modes are only intended for consistently slippery or loose
surfaces.
•Drive slower in strong crosswinds which can affect the normal steering
characteristics of your vehicle.
•Be extremely careful when driving on pavement made slippery by
loose sand, water, gravel, snow or ice.
If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
