Electronic stability control (ESC)
Electronic stability control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During ESC events the stability control light in the instrument cluster
will flash.
Certain adverse driving maneuvers may activate the ESC system, which
include but are not limited to:
•Taking a turn too fast
•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).
The electronic stability control system may be deactivated in certain
situations. See theSwitching off AdvanceTracwith RSCsection
following.
Roll Stability Controlâ„¢ (RSC)
Roll Stability Controlâ„¢ (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 RSCthe stability control light in the
instrument cluster will flash.
Certain adverse driving maneuvers may activate the RSCsystem, which
include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
The RSCsystem may be deactivated in certain situations. See the
Switching off AdvanceTracwith RSCsection following.

Switching off AdvanceTracwith RSC
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTracwith RSC
system 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 AdvanceTracwith RSCsystem, select traction
control off in the message center. Full features of the AdvanceTracwith
RSCsystem can be restored by selecting traction control on, or by
turning off and restarting the engine.
If you switch off the AdvanceTrac
with RSCsystem, the stability
control off light will illuminate
steadily. Selecting traction control
on will turn off the stability control
light.
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
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. Trailer sway control is only enabled above
40 mph (64 km/h).
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 message center will also
displayTRAILER SWAY REDUCE SPEED.In some cases when trailer
sway is detected, the vehicle speed is too high and may be at or above a
speed at which trailer sway will grow continuously. This may cause the
system to activate multiple times, and you may experience a slight
deceleration of the vehicle.
Disabling trailer sway control
Trailer sway control can be disabled during any key cycle. Refer to
Message centerin theInstrument Clusterchapter for more information.
Note that even if it was disabled before turning off the vehicle, 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
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering fluid level
(below the MIN mark on the reservoir).
•Some noise is normal during operation. If the noise is excessive, check
for a low power steering fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by a low power
steering fluid level. Check for a low power steering fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering fluid reservoir above the MAX mark on
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:
•An improperly inflated tire
•Uneven tire wear
•Loose or worn suspension components
•Loose or worn steering components
•Improper steering alignment
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
BRAKE-SHIFT INTERLOCK
This vehicle is equipped with a brake-shift interlock (BSI) feature that
prevents the gearshift lever from being moved from P (Park) when the
ignition is in the on position unless the brake pedal is pressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the on position and the brake pedal pressed, it is possible that a fuse has
blown or the vehicle’s brake lamps are not operating properly. Refer to
Fuses and relaysin theRoadside Emergencieschapter.

working properly. See your authorized dealer.
AUTOMATIC TRANSMISSION OPERATION
Automatic transmission adaptive learning
Your transmission is equipped with an adaptive learning strategy found in
the vehicle computer. This feature is designed to increase durability and
provide consistent shift feel over the life of the vehicle. A new vehicle or
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation. Additionally, whenever the battery is
disconnected or a new battery installed, the strategy must be relearned.
Understanding the gearshift positions of the 6–speed automatic
transmission
P (Park)
This position locks the transmission
and prevents the front wheels from
turning.
To put your vehicle in gear:
•Press the brake pedal
•Move the gearshift lever into the
desired gear
To put your vehicle in P (Park):
•Come to a complete stop

Recommended shift speeds
Upshift according to the following chart:
Upshifts when accelerating
(recommended for best fuel economy)
Shift from:
1 - 2 15 mph (24 km/h)
2 - 3 25 mph (40 km/h)
3 - 4 40 mph (64 km/h)
4 - 5 45 mph (72 km/h)
5 - 6 50 mph (80 km/h)
The message center display in the instrument cluster will show the
current selected gear you are in.
In order to prevent the engine from running at too low an RPM, which
may cause it to stall, the SST will automatically make some downshifts
even if it has determined that you have not downshifted in time. 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.
Engine damage may occur if excessive engine revving is held
without shifting.
Hill start assist (HSA) system
The hill start assist system makes it easier to pull away when the vehicle
is on a slope without the need to use the parking brake. When hill start
assist is active, the vehicle will remain stationary on the slope for up to
three 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 system 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
Hill start assist is activated automatically when the vehicle is stopped on
a slope greater than five degrees. Hill start assist operates with the
vehicle facing downhill if reverse gear is selected.
WARNING:You must remain in the vehicle once you have
activated hill start assist.
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, hill start assist 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 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.
WARNING:If the engine is revved excessively, or if a
malfunction is detected when hill start assist is active, hill start
assist will be deactivated.
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 between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on 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.
It may be beneficial to turn the AdvanceTracwith RSC system off so
the wheels are allowed to spin.

COLLISION WARNING SYSTEM (IF EQUIPPED)
The collision warning with brake support, is designed to alert the driver
of certain collision risks with a red warning light located above the
dashboard and an audible warning chime. The brake support assists the
driver in reducing the collision speed, by pre-charging the brakes.
WARNING:This system is designed to be a supplementary
driving aid. It is not intended to replace the driver’s attention,
and judgment, or the need to apply the brakes. This system does NOT
activate the brakes automatically. Failure to press the brake pedal to
activate the brakes may result in a collision.
WARNING:The collision warning system with brake support
cannot help prevent all collisions. Do not rely on this system to
replace driver judgment and the need to maintain distance and speed.
Note:The collision warning with brake support will not detect, warn, or
respond to potential collisions with vehicles to the rear or sides of the
vehicle.
