2012 FORD EXPEDITION engine

•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter).
Roll Stability Control™ (RSC)
Roll Stability Control™ (RSC) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSCoperates by detecting the
vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.
During an event that activates the RSCsystem, the stability control
light in the instrument cluster will flash.
Certain adverse driving maneuvers may activate the Roll Stability Control
system, which include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
Switching off traction control
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off the traction control features of the AdvanceTrac
with RSCsystem may be beneficial because the wheels are allowed to
spin. This will restore full engine power and will enhance momentum
through the obstacle. To switch off the traction control, press the
stability control button. Full features of the AdvanceTracwith RSC
system can be restored by pressing the stability control button again or
by turning off and restarting the engine.
If you switch off the traction control, the stability control off light will
illuminate steadily. Pressing the stability control button again will turn off
the stability control light.
In 4L (4X4 Low) if equipped, ABS and the brake traction control
features will continue to function; however ESC, RSC and engine traction
control are disabled.
In R (Reverse), ABS and the engine traction control and brake traction
control features will continue to function; however, ESC and RSCare
disabled.

Trailer sway control
Your vehicle may be equipped with trailer sway control. When properly
equipped, trailer sway control will use the vehicle’s AdvanceTracwith
RSCsystem to detect and help reduce trailer sway by applying brake
force at individual wheels and, if necessary, by reducing engine power.
WARNING:Trailer sway control does not prevent a trailer from
swaying, it mitigates the sway from increasing once it has
occurred. If you are experiencing trailer sway it is likely that the trailer
is improperly loaded for the correct tongue weight or the speed of the
vehicle and trailer is too high. Pull the vehicle-trailer over to a safe
location to check the trailer weight distribution and tongue load and
reduce speed to a safe level while towing. If trailer sway is
experienced, SLOW DOWN.
During trailer sway control events, the stability control light in the
instrument cluster will flash momentarily. The cluster message center
will also display TRAILER SWAY REDUCE SPEED. In some cases when
trailer sway is detected, the vehicle speed is too high and may be above
a speed at which trailer sway will not grow continuously. This may cause
the system to activate multiple times, causing a gradual reduction in
speed.
Note:The trailer sway control will only activate at speeds greater than
40 mph (64 km/h).

Disabling trailer sway control
Trailer sway control can be disabled during any key cycle. SeeMessage
centerin theInstrument Clusterchapter. Note that regardless of chosen
enable state, trailer sway control will be re-enabled at each new key cycle.
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury, or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (e.g., hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the MIN mark on the reservoir.
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components

WARNING:Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
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.
AUTOMATIC TRANSMISSION OPERATION
Driving with a 6–speed automatic transmission
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down, the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
This vehicle is equipped with an Adaptive Transmission Shift Strategy.
The Adaptive Transmission Shift Strategy offers the optimal transmission
operation and shift quality. When the engine is turned off, the shift data
which includes the adaptive information will be stored automatically in
the Powertrain Control Module (PCM). If the battery is disconnected for
any reason, the stored information from the last time the key was turned
to OFF will be read. This way, no information will be lost with any
battery removal or battery disconnect.

Tow/Haul can be activated by pressing the transmission control switch on
the end of the gearshift lever (column-shift transmission) or on the side
of the gearshift lever (floor-shift transmission).
•Column-shift transmission
•Floor-shift transmission
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 accelerator pedal
being pressed. The amount of downshift braking provided will vary based
upon the amount the brake pedal is depressed.
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.
When you shut-off and restart the engine, the transmission will
automatically return to normal D (Overdrive) mode (Tow/Haul OFF).

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.
3 (Third) (column-shift only)
Transmission operates in third gear only.
Used for improved traction on slippery roads.
2 (Second)
Transmission operates in 2nd gear only.
