2013 FORD F250 Owners Manual

HILL START ASSIST
WARNING:The hill start assist feature does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and shift the transmission into P (Park).
WARNING:You must remain in the vehicle once you have
activated the hill start assist feature.
WARNING:During all times, you are responsible for controlling
the vehicle, supervising the hill start assist system and
intervening, if required.
WARNING:If the engine is revved excessively, or if a
malfunction is detected when the hill start assist feature is
active, the hill start assist feature will be deactivated.
Hill start assist keeps your vehicle stationary long enough to move your
foot from the brake pedal to the accelerator pedal when your vehicle is
on a slope.
The brakes are released automatically once the engine has developed
sufficient drive to prevent the vehicle from rolling down the slope. This
is an advantage when pulling away on a slope, (for example from a car
park ramp, traffic lights or when reversing uphill into a parking space).
Using Hill Start Assist
1. Press the brake pedal to bring the vehicle to a complete standstill.
Keep the brake pedal pressed.
2. If the sensors detect that the vehicle is on a slope, the hill start assist
feature will be activated automatically.
3. When you remove your foot from the brake pedal, the vehicle will
remain on the slope without rolling away for approximately two or three
seconds. This hold time will automatically be extended if you are in the
process of driving off.
4. Drive off in the normal manner. The brakes will be released
automatically.

USING FOUR-WHEEL DRIVE (4WD) (IF EQUIPPED )
WARNING:For important information regarding safe operation
of this type of vehicle, seeGeneral Informationin theWheels
and Tireschapter.
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 toShifting 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 (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/from 4L (4X4 Low)
for proper system operation.

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 recommended AUTO lock
mode.
4WD Indicator Lights
The indicator lights illuminate in the message center in the
reconfigurable telltale (RTT) location under the following conditions.
Refer toWarning Lamps and Indicatorsin theInstrument Cluster
chapter.
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.

Electronic Locking Differential (ELD) (If Equipped)
Note:The ELD is designed for off-road use only and is not intended for
use on dry pavement. Using the ELD on dry pavement will result in
increased tire wear, noise and vibration.
The electronic locking differential (ELD) is a device housed in the rear
axle which allows both rear wheels to turn at the same speed. It provides
added traction on slippery and/or off road surfaces, particularly when
one wheel is on a poor traction surface. The ELD may be locked or
unlocked by the vehicle operator and can be engaged or disengaged on
the fly. When the axle is unlocked it will function like a standard rear
axle. When the axle is locked it will not allow the rear wheels to rotate
at different speeds when turning.
The ELD is affected by the following conditions:
•
On 2WD vehicles and 4WD vehicles in 2H (4X2) or 4H (4X4 High), the
ELD will not engage if the vehicle speed is above 20 mph (32 km/h).
•On 2WD vehicles and 4WD vehicles in 2H (4X2) or 4H (4X4 High), the
ELD will automatically disengage at speeds above 25 mph (40 km/h) and
will automatically reengage at speeds below 20 mph (32 km/h).
•On 4WD vehicles in 4L (4X4 Low), the ELD can be engaged at any
speed and will not automatically disengage.

Activating the Electronic Locking Differential (ELD)
Note:The ELD may have difficulty disengaging either by operator
command or automatically if the driveline is under torque. If driving
conditions allow, releasing the accelerator pedal or turning the steering
wheel in the opposite direction may assist in disengagement.
Note:The ELD is designed for off-road use only and is not intended for
use on dry pavement.
For vehicles equipped with an
electronic shift 4WD system:
Pull the 4WD control knob toward
you.
For 2WD vehicles and vehicles
equipped with a manual shift
4WD system:
Turn the control to ON.
Once the indicator light is displayed in the information display,
both rear wheel axle shafts will be locked together providing
added traction.
If the indicator does not come on, or the indicator turns off while
driving, one of the following has occurred:
•The vehicle speed is too high.
•The left and right rear wheel speed difference is too high during an
engagement attempt.
•The system has malfunctioned and will be accompanied by a message
in the information display. See your authorized Ford dealer for
