D (Overdrive) with Tow/Haul On
The tow/haul feature improves transmission operation when towing a
trailer or a heavy load. All transmission gear ranges are available when
using tow/haul.
To activate tow/haul, press the
button on the end of the gearshift
lever.
The TOW HAUL indicator light will
illuminate in the instrument cluster.
Tow/haul delays upshifts to reduce frequency of transmission shifting.
Tow/haul also provides engine braking in all forward gears when the
transmission is in the D (Overdrive) position; this engine braking will
slow the vehicle and assist the driver in controlling the vehicle when
descending a grade. Depending on driving conditions and load
conditions, the transmission may downshift, slow the vehicle and control
the vehicle speed when descending a hill, without the brake pedal being
pressed. The amount of downshift braking provided will vary based upon
the amount the brake pedal is pressed.
Tow/haul may be automatically activated (without pressing the tow/haul
button). This provides engine braking to assist the vehicles braking
system when going downhill and repetitive braking is sensed. Once the
tow/haul mode has been automatically activated it will not automatically
deactivate.
To deactivate the tow/haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The tow/haul light will
no longer be illuminated.
Tow/haul will also deactivate when the vehicle is powered down for a few
minutes.
WARNING:Do not use the tow/haul feature when driving in icy
or slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.

Although the SST will make some downshifts for you, it will still allow
you to downshift at any time as long as the SST determines that the
engine will not be damaged from over-revving.
The SST will not automatically upshift, even if the engine is approaching
the RPM limit. It must be shifted manually by pressing the + button.
Engine damage may occur if excessive engine revving is held
without shifting.
Hill start assist (HSA)
The hill start assist feature makes it easier to pull away when the vehicle
is on a slope without the need to use the parking brake. When the hill
start assist feature is active, the vehicle will remain stationary on the
slope for up to two seconds after you release the brake pedal. During
this time, you have time to move your foot from the brake to the
accelerator pedal and pull away. 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.
WARNING:The hill start assist feature does not replace the
parking brake. When you leave the vehicle, always apply the
parking brake and select first or reverse gear.
Using hill start assist
The hill start assist feature is activated automatically when the vehicle is
stopped on a slope greater than five degrees. The hill start assist feature
operates with the vehicle facing downhill if reverse gear is selected. The
hill start assist feature will not operate if the parking brake is activated.
WARNING:You must remain in the vehicle once you have
activated the hill start assist feature.
Activating 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 up to two
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.
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.
If your vehicle gets stuck in mud or snow
Note:Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Note:Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
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
steady pattern. Press lightly on the accelerator in each gear.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The reverse sensing system (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not
effective at speeds above 3 mph (5 km/h) and may not detect certain
angular or moving objects.
WARNING:To help avoid personal injury, please read and
understand the limitations of the reverse sensing system as
contained in this section. Reverse sensing is only an aid for some
(generally large and fixed) objects when moving in reverse on a flat
surface at “parking speeds”. Inclement weather may also affect the
function of the RSS; this may include reduced performance or a false
activation.
WARNING:To help avoid personal injury, always use caution
when in reverse and when using the RSS.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller
objects, particularly those close to the ground.

WARNING:The camera system is a reverse aid supplement
device that still requires the driver to use it in conjunction with
the rear view mirror and the side mirrors for maximum coverage.
WARNING:Objects that are close to either corner of the
bumper or under the bumper, might not be seen on the screen
due to the limited coverage of the camera system.
WARNING:Back up as slow as possible since higher speeds
might limit your reaction time to stop the vehicle.
WARNING:Do not use the camera system with the tailgate
open.
If the back end of the vehicle is hit or damaged, then check with your
authorized dealer to have your rearview camera system checked for
proper coverage and operation.
Night time and dark area use
At night time or in dark areas, the camera system relies on the reverse
lamp lighting to produce an image. Therefore it is necessary that both
reverse lamps are operating in order to get a clear image in the dark. If
either of the lamps are not operating, stop using the camera system, at
least in the dark, until the lamp(s) are replaced and functioning.
Servicing
•If the image comes on while the vehicle is not in R (Reverse), have
the system inspected by your authorized dealer.
•If the image is not clear, then check if there is anything covering the
lens such as dirt, mud, ice, snow, etc. If the image is still not clear
after cleaning, have your system inspected by your authorized dealer.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
WARNING: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.

•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.
WARNING:Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles arenotdesigned for cornering at speeds as high as passenger
cars any more than low-slung sports cars are designed to perform
satisfactorily under off-road conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
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
steady pattern. Press lightly on the accelerator in each gear.
If your vehicle is severely stuck, it may need to be pulled out. Front
tow/recovery hooks can be used to recover a vehicle struck in the mud
or snow. Refer toRecovery hooksin theTires, Wheels and Loading
chapter for more information.
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.

WARNING:Always set the parking brake fully and make sure
the gearshift is latched in P (Park). Turn the ignition to the off
position and remove the key whenever you leave your vehicle.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
4WD systems
4WD (when you select a 4WD mode), uses all four wheels to power the
vehicle. This increases traction, enabling you to drive over terrain and
road conditions that a conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels through a transfer case. On 4WD
vehicles, the transfer case allows you to select 4WD when necessary.
Information on transfer case operation and shifting procedures can be
found in theDrivingchapter. Information on transfer case maintenance
can be found in theMaintenance and Specificationschapter. You
should become thoroughly familiar with this information before you
operate your vehicle.
Normal characteristics
On some 4WD models, the initial shift from two-wheel drive to 4x4 while
the vehicle is moving can cause some momentary clunk and ratcheting
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, try to 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 steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
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.
Note:If air is released from your tires, the Tire Pressure Monitoring
System (TPMS) indicator light may illuminate (if equipped).

•Shift transfer case to 4H (4x4 High) when plowing larger areas or light
snow at higher speeds. Do not exceed 15 mph (24 km/h).
•Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
•If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a few minutes. The transmission and tires may be damaged or
the engine can overheat.
Do not rock the vehicle if the engine is not at normal operating
temperature. Do not rock the vehicle for more than a minute. The
transmission and tires may be damaged or the engine may
overheat.
Refer toGaugesin theInstrument Clusterchapter for transmission
fluid temperature information.
WARNING:Do not spin the wheels at over 35 mph (55 km/h).
The tires may fail and injure a passenger or bystander.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note:If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the indicator light will illuminate when the spare tire is
in use. To restore the full functionality of the monitoring system, all road
wheels equipped with tire pressure monitoring sensors must be mounted
on the vehicle.
If your vehicle is equipped with TPMS, have a flat serviced by an
authorized dealer in order to prevent damage to the TPMS sensors, refer
toTire pressure monitoring system (TPMS)in theTires, Wheels and
Loadingchapter. Replace the spare tire with a road tire as soon as
possible. During repairing or replacing of the flat tire, have the
authorized dealer inspect the TPMS sensor for damage.
WARNING:The use of tire sealants may damage your tire
pressure monitoring system (TPMS) and should not be used.
However, if you must use a sealant, the TPMS sensor and valve stem
on the wheel must be replaced by an authorized Ford dealer.
