display FORD F150 2009 12.G Repair Manual

The RSS automatically turns on when the gear selector is placed in R
(Reverse) and the ignition is on. A control in the message center allows
the driver to disable the system only when the ignition is on and the
gear selector is in R (Reverse). Refer toMessage centerin theDriver
Controlschapter for more information.
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.
REVERSE CAMERA SYSTEM (IF EQUIPPED)
The reverse camera system, located
on the tailgate under the Ford Oval
badge, provides a video image,
which appears in the rear view
mirror or the navigation system (if
equipped), of the area behind the
vehicle. It adds assistance to the
driver while reversing or reverse
parking the vehicle.
To use the reverse camera system,
place the transmission in R
(Reverse); an image will display on
the left portion of the rear view
mirror or on the navigation screen
(if equipped). The area displayed on
the screen may vary according to
the vehicle orientation and/or road
condition.
•(1) Rear bumper
•(2) Red zone

System indicator lights
•4X2- Momentarily illuminates
when 2H is selected on electronic
shift 4WD systems only.
•4X4 HIGH- Illuminates when 4H
is selected.
•4X4 LOW– Illuminates when 4L
is selected.
Note:When a 4X4 system fault is present, the warningCHECK 4X4
will display in the message center. The system will typically remain in
whatever 4X4 mode was selected prior to the fault condition occurring. It
will not default to 4X2. When this warning is displayed, have your vehicle
serviced at an authorized dealer.
Using a manual 4WD system (if equipped)
2H (2WD High)– Power to the rear wheels only; used for street and
highway driving. Provides optimal smoothness and fuel economy at high
speeds.
4H (4WD High)– Used for extra traction such as in snow or icy roads
or in off-road situations. Not intended for use on dry pavement.
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 only for off-road applications
such as deep sand, steep grades or pulling heavy objects. The shift lever
will not engage 4L (4X4 LOW) until the transmission is in N (neutral)
and the vehicle is moving below 3 mph (5 km/h); 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 between 2H (2WD High) and 4H (4WD
High) at a stop or any forward speed.
Note:Do not perform this operation if the rear wheels are slipping.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Shifting to/from 4L (4WD Low)
1. Bring the vehicle to a speed of 3 mph (5 km/h) or less.
2. Place the transmission in N (Neutral).
3. Move the transfer case lever through N (Neutral) directly to the
desired position.
•If the transfer casewill notengage into 4L (4WD Low)do not force
the lever.Allow the vehicle to coast at a speed below 3 mph
(5 km/h), then repeat Steps 2 and 3.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Note:For proper operation in 4WD Low, ensure the transfer case shift
lever is moved entirely rearward in to the 4L (4WD Low) position and
that the 4x4 Low light is displayed in the message center.
Note:Ideal 4L (4WD Low) shift conditions occur when the vehicle is
rolling at a speed below 3 mph (5 km/h) and the transmission is in N
(Neutral).
Using the N (Neutral) position
The transfer case N (Neutral) position overrides the transmission
and puts the vehicle in neutral regardless of transmission
gearshift lever position. The vehicle can move forward or
backward.
This position should only be used when towing the vehicle.

WARNING: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.
Using the electronic shift 4WD system (if equipped)
2H (2WD High)- Power to the rear wheels only; used for street and
highway driving. Provides optimal smoothness and fuel economy at high
speeds.
4H (4WD High)- Used for extra traction such as in snow or icy roads
or in off-road situations. Not intended for use on dry pavement.
4L (4WD Low)- Uses extra gearing to provide maximum power to all
four wheels at reduced speeds. Intended only for off-road applications
such as deep sand, steep grades or pulling heavy objects. 4L (4WD Low)
will not engage while the vehicle is moving above 3 mph (5 km/h); 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 4WD control between 2H and 4H at any forward speed.
The message center will display4X4 SHIFT IN PROGRESSduring the
system shift. “4x4 HIGH” will display in the message center.
Note:Do not perform this operation if the rear wheels are slipping.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Shifting to/from 4L (4WD Low)
1. Bring the vehicle to a speed of 3 mph (5 km/h) or less.
2. Place the transmission in N (Neutral).

3. Move the 4WD control to the desired position.
The message center will display4X4 SHIFT IN PROGRESSduring the
shift. The message center will then display the system mode selected.
If any of the above shift conditions are not met, the shift will not occur
and the message center will display information guiding the driver
through the proper shifting procedures.
If 4X4 SHIFT IN PROGRESS is displayed for more than five
seconds, transfer case gear tooth blockage is present. To alleviate
this condition, move the vehicle forward approximately five feet
(2 meters). If a blocked shift remains present, reset the 4X4
mode select switch to the desired mode. The system will
reattempt a shift.
Note:Some noise may be heard as the system shifts or engages; this is
normal.
Electronic locking differential (ELD) (if equipped)
The electronic locking differential (ELD) is a device housed in the rear
axle which allows both rear wheels to turn at the same speed. The ELD
can provide additional traction should the vehicle become stuck. The
ELD is electronically activated by the driver and can be shifted on the
fly. It is intended for use in mud, rocks, sand, or any off-road condition
where maximum traction is needed. It is not intended for use on dry
pavement.
The ELD is affected by the following conditions:
•The 4WD control must be in either 4H or 4L mode.
•The ELD will not engage if the vehicle speed is above 20 mph
(30 km/h) in 4X4 High or 56 mph (90 km/h) in 4X4 Low.
•In 4X4 High, the ELD will disengage at speeds above 25 mph
(40 km/h) and will automatically reengage at speeds below 20 mph
(30 km/h).
•In 4X4 Low, the ELD will disengage at speeds above 62 mph
(100 km/h) and will automatically reengage at speeds below 56 mph
(90 km/h).
•The ELD will not engage if one wheel is spinning 9 mph (15 km/h)
faster than the other.
The ELD is designed for off-road use only.
