2003 FORD SUPER DUTY lock

•Depress the accelerator to the floor.
•Allows transmission to select an appropriate gear.
Shift strategy (4R100 automatic transmission)
To account for customer driving habits and conditions, your 4R100
automatic transmission electronicallycontrols the shift qualitybyusing
an adaptive learning strategy. The adaptive learning strategy is
maintained bypower from the battery. When the batteryis disconnected
or a new batteryis installed, the transmission must relearn its adaptive
strategy. Optimal shifting will resume within a few hundred kilometers
(miles) of operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally, see your dealer or a
qualified service technician as soon as possible.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting from forward and reverse gears, stopping between shifts in a
steadypattern. Press lightlyon the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Using the clutch
The manual transmission has a starter interlock that prevents cranking
the engine unless the clutch pedal is fullydepressed.
To start the vehicle:
1. Make sure the parking brake is fullyset.
2. Press the clutch pedal to the floor, then put the gearshift lever in the
neutral position.

3. Start the engine, then press the brake pedal and release the parking
brake.
4. Move the gearshift lever to the desired gear, then slowlyrelease the
clutch pedal while slowlypressing on the accelerator.
Do not drive with your foot resting on the clutch pedal or use the clutch
pedal to hold your vehicle at a standstill while waiting on a hill. These
actions will reduce the life of the clutch.
Recommended shift speeds
Downshift according to the following charts for your specific
engine/drivetrain combination:

Reverse
1. Make sure that your vehicle is at a complete stop before you shift into
R (Reverse). Failure to do so maydamage the transmission.
2. Move the gearshift lever into the neutral position and wait at least
three seconds before shifting into R (Reverse).
•The gearshift lever can onlybe moved into R (Reverse) bymoving it
from left of 3 (Third) and 4 (Fourth) before shifting into R (Reverse).
This is a lockout feature that protects the transmission from
accidentallybeing shifted into R (Reverse) from
(Overdrive).
Parking your vehicle
1. Applythe brake and shift into the neutral position.
2. Fullyapplythe parking brake, then shift into 1 (First).
3. Turn the ignition off.

The RSS detects obstacles up to 2
meters (6 ft.) from the rear bumper
with a decreased coverage area at
the outer corners of the bumper,
(refer to the figures for approximate
zone coverage areas). As you move
closer to the obstacle, the rate of
the tone increases. When the
obstacle is less than 25.0 cm
(10 in.) away, the tone will sound
continuously. If the RSS detects a
stationaryor receding object further
than 25.0 cm (10 in.) from the side
of the vehicle, the tone will sound
for onlythree seconds. Once the
system detects an object
approaching, the tone will sound
again.
The RSS mayhave reduced
performance or an increased chance
of false detection if the tailgate is
not locked and in the upright position. If the tailgate is down, the RSS
tone maybe heard intermittentlyor continuously. The tone mayalso be
heard if items in the truck bed protrude rearward outside the bed.
The RSS automaticallyturns on
when the gear selector is placed in
R (Reverse) and the ignition is ON.
An RSS control allows the driver to
turn the RSS on and off. To turn the
RSS off, the ignition must be ON,
and the gear selector in R
(Reverse). An indicator light on the
control will illuminate when the
system is turned off. If the indicator light illuminates when the RSS is
not turned off, it mayindicate a failure in the RSS.
Keep the RSS sensors (located on the rear bumper/fascia) free
from snow, ice and large accumulations of dirt (do not clean the
sensors with sharp objects). If the sensors are covered, it will
affect the accuracy of the RSS.
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.
Four–wheel drive (4WD) supplies power to all four wheels. 4WD should
not be operated on drypavement; driveline damage mayoccur.
If equipped with the Electronic Shift 4WD System, and 4WD Low
is selected while the vehicle is moving, the 4WD system will not
engage. This is normal and should be no reason for concern.Refer
toShifting to/from 4WD Lowfor proper operation.
The 4WD system also uses hub locks that can be engaged and
disengaged based on the 4WD mode selected. Refer toFront wheel hub
locks (if equipped)for more information.
4WD system indicator lights
•4X4- illuminates when 4WD High
is selected.
•LOW RANGE- illuminates when
4WD Low is selected.

Engage or disengage the 4WD system by:
•rotating the control for both front wheel hub locks from the FREE or
LOCK position, then
•manuallyengage or disengage the transfer case with the floor-mounted
shifter
For increased fuel economyin 2WD, rotate both hub locks to the FREE
position.
For proper operation, make sure that the arrow and the indicator
dot on the hub are aligned, and that both hub locks are set to the
same position (both set to LOCK or both set to FREE).
Using a manual 4WD system (if equipped)
2H (2WD High)– Power to the rear wheels only; used for street and
highwaydriving.
4H (4WD High)– Used for extra traction such as in snow or icyroads
or in off-road situations. Not intended for use on drypavement.
N (Neutral)– No power to either front or rear wheels.
4L (4WD Low)– Uses extra gearing to provide maximum power to all
four wheels at reduced speeds. Intended onlyfor off-road applications
such as deep sand, steep grades or pulling heavyobjects. 4L (4WD Low)
will not engage while the vehicle is moving; this is normal and should be
no reason for concern. Refer toShifting to/from 4L (4WD Low)for
proper operation.
Shifting between 2H (2WD high) and 4H (4WD high)
•Move the transfer case lever to 4H (4WD High) at a stop or any
forward speed up to 88 km/h (55 mph).
Note:Do not perform this operation at speeds above 72 km/h (45 mph)
if the outside temperature is below 0°C (32°F).

If your vehicle gets stuck
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
steadypattern. Press lightlyon the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fullyreleased, but the brake warning lamp
remains illuminated, the brakes maynot be working properly.
See your dealer or a qualified service technician.
Do not spin the wheels at over 56 km/h (35 mph). The tires may
fail and injure a passenger or bystander.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
Emergency maneuvers
•In an unavoidable emergencysituation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle, i.e.,
turn the steering wheel onlyas rapidlyand as far as required to avoid
the emergency. Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergencystop, avoid skidding the tires and do not
attempt anysharp steering wheel movements.

sounds. This is the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not cause for concern.
Sand
When driving over sand, tryto keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadilythrough the terrain. Applythe accelerator slowly
and avoid spinning the wheels.
If you must reduce the tire pressure for whatever reason in sand, make
sure you re-inflate the tires as soon as possible.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capabilitymaybe limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the
vehicle maystall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectivelyas drybrakes. Drying can be improved bymoving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, applythe accelerator slowlyand avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.

Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral; instead,
disengage overdrive or manually
shift to a lower gear. When
descending a steep hill, avoid
sudden hard braking as you could
lose control. When you brake hard,
the front wheels can’t turn and if
theyaren’t turning, you won’t be
able to steer. The front wheels have to be turning in order to steer the
vehicle. Rapid pumping of the brake pedal will help you slow the vehicle
and still maintain steering control.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
“pump” the brakes.
Driving on snow and ice
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like anyother vehicle.
Should you start to slide while driving on snowyor icyroads, 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. Applythe accelerator slowlyand steadilywhen starting
from a full stop.
Avoid sudden braking as well. Although a 4WD vehicle mayaccelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, 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 emergencystopping situations, avoid locking of the wheels. Use
a “squeeze” technique, push on the brake pedal with a steadilyincreasing
force which allows the wheels to brake yet continue to roll so that you
may steer in the direction you want to travel. If you lock the wheels,
release the brake pedal and repeat the squeeze technique. If your vehicle
is equipped with a Four Wheel Anti-Lock Brake System (ABS), apply the
brake steadily. Do not “pump” the brakes. Refer to theBrakessection of
this chapter for additional information on the operation of the anti-lock
brake system.
