HINTS ON DRIVING WITH ANTI-LOCK BRAKES
When the system is operating, the brake pedal will pulse and may travel
further. Maintain pressure on the brake pedal. You may also hear a noise
from the system. This is normal.
The anti-lock braking system will not eliminate the risks when:
•You drive too closely to the vehicle in front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
PARKING BRAKE
WARNING: Always set the parking brake fully and make sure
that the transmission is securely latched in park (P).
To set the parking brake, press the parking brake pedal down until the
pedal stops.
The brake warning lamp will illuminate and will remain illuminated until
the parking brake is released.
To release, pull the brake release lever located at the lower left side of
the instrument panel.
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 park (P).
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.

SENSING SYSTEM (IF EQUIPPED)
WARNING:To help avoid personal injury, please read and
understand the limitations of the system as contained in this
section. Sensing is only an aid for some (generally large and fixed)
objects when moving in reverse on a flat surface at parking speeds.
Traffic control systems, inclement weather, air brakes, and external
motors and fans may also affect the function of the sensing system; this
may include reduced performance or a false activation.
WARNING: To help avoid personal injury, always use caution
when in R (Reverse) and when using the sensing system.
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: Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the normal
detection zone of the system, may create false beeps.
Note: Keep the sensors (located on the bumper/fascia) free from snow,
ice and large accumulations of dirt. If the sensors are covered, the
system’s accuracy can be affected. Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to the bumper/fascia, leaving it
misaligned or bent, the sensing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
Note: If your vehicle is equipped with MyKey®, it is possible to prevent
turning the sensing system off. Refer to the MyKey®chapter.
Note: When a trailer is connect to your vehicle, the Rear Sensing System
may detect the trailer and provide warnings. It is suggested that the
driver disables the Rear Sensing System when a trailer is connected to
your vehicle to prevent these warnings.
The sensing system warns the driver of obstacles within a certain range
of the bumper area. The system turns on automatically whenever the
ignition is switched on.

Using the Systems
BLIS® turns on when the engine is started and the vehicle is driven
forward above 3 mph (5 km/h); it remains on while the transmission is in
D (Drive) or N (Neutral). If shifted out of D (Drive) or N (Neutral), the
system enters CTA mode. Once shifted back into D (Drive), BLIS® turns
back on when the vehicle is driven above 3 mph (5 km/h).
Note:BLIS® does not function in R (Reverse) or P (Park) or provide
any additional warning when a turn signal is on.
CTA detects approaching vehicles from up to 45 feet (14 meters) away
though coverage decreases when the sensors are blocked. Reversing
slowly helps increase the coverage area and effectiveness.
WARNING: To help avoid personal injury, NEVER use the CTA
system as a replacement for using the interior and exterior
mirrors and looking over your shoulder before backing out of a parking
space. CTA is not a replacement for careful driving.
In this first example, the left sensor is only partially obstructed; zone
coverage is nearly maximized.

System Sensors
WARNING:Just prior to the system recognizing a blocked
condition and alerting the driver, the number of missed objects
will increase. To help avoid injuries, NEVER use the BLIS® as a
replacement for using the side and rear view mirrors and looking over
your shoulder before changing lanes. BLIS® is not a replacement for
careful driving.
Note: It is possible to get a blockage warning with no blockage present;
this is rare and known as a false blockage warning. A false blocked
condition either self-corrects or clears after a key cycle.
The system uses radar sensors
which are located behind the
bumper fascia on each side of the
vehicle. Do not allow these areas to
become obstructed by mud, snow or
bumper stickers, as this can cause
degraded system performance.
If the system detects a degraded performance condition, a blocked
sensor warning or low visibility warning will appear in the information
display and the alert indicator illuminates in the appropriate mirror(s).
The information display warning can be cleared but the alert indicator
remains illuminated.
When the blockage is removed, the system can be reset in two ways: 1)
when at least two objects are detected while driving, or 2) turn the
ignition key from on to off, then back on. If the blockage is still present
after the key cycle, the system senses again that it is blocked after
driving in traffic.

Reasons for messages being displayed
The radar surface is
dirty or obstructed Clean the fascia area in front of the radar or
remove the obstruction.
The radar surface is
not dirty or obstructed Drive normally in traffic for a few minutes to
allow the radar to detect passing vehicles so it
can clear the blocked state.
Heavy rainfall/snowfall
interferes with the
radar signals No action required. The system automatically
resets to an unblocked state once the
rainfall/snowfall rate decreases or stops. Do
not use BLIS® and/or CTA in these conditions.
System Limitations
The BLIS® and CTA systems do have their limitations; situations such as
severe weather conditions or debris build-up on the sensor area may
limit vehicle detection.
The following are other situations that may limit the BLIS®:
• Certain maneuvering of vehicles entering and exiting the blind zone.
• Vehicles passing through the blind zone at very fast rates.
• When several vehicles forming a convoy pass through the blind zone.
The following are other situations that may limit the CTA system:
• Adjacently parked vehicles or objects obstructing the sensors.
• Approaching vehicles passing at speeds greater than 15 mph
(24 km/h).
• Driving in reverse faster than 3 mph (5 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If you connected a trailer to your vehicle the BLIS® system may
detect the trailer causing a false alert. To avoid false alerts you may want
to turn the BLIS off manually.
There may be certain instances when either the BLIS® or CTA systems
illuminate the alert indicator with no vehicle in the coverage zone; this is
known as a false alert. Some amount of false alerts are normal; they are
temporary and self-correct.

ROOF RACKS AND LOAD CARRIERS
WARNING:When loading the roof rail crossbars, it is
recommended to evenly distribute the load, as well as maintain a
low center of gravity. Loaded vehicles, with higher centers of gravity,
may handle differently than unloaded vehicles. Extra precautions, such
as slower speeds and increased stopping distance, should be taken
when driving a heavily loaded vehicle.
Note: The maximum recommended load is 200 pounds (90 kilograms),
evenly distributed on the crossbars.
Note: Loads should never be placed directly on the roof panel. The roof
panel is not designed to directly carry a load.
For proper function of the roof rack system, loads must be placed
directly on crossbars affixed to the roof rack side rails. Your vehicle may
be equipped with factory-installed crossbars. Ford Genuine Accessory
crossbars, designed specifically for your vehicle, are also recommended
for use with your roof rack system.
Make sure that the load is securely fastened. Check the tightness of the
load before driving and at each fuel stop.
Adjusting the Crossbars (If Equipped)
1. Loosen the thumbwheels at both ends of the
crossbar by turning them counterclockwise (both
crossbars are adjustable).
2. Slide the crossbar to the desired location.
3. Tighten the thumbwheels at both ends of the
crossbar by turning them clockwise.
Make sure to check that the thumbwheels are tight each time a load is
added or removed from the roof rack, and periodically while traveling.
Make sure that the load is secure before traveling.

POWER DEPLOYABLE RUNNING BOARDS (IF EQUIPPED)
WARNING:In extreme climates, excessive ice buildup may
occur, causing the running boards not to deploy. Be sure that the
running boards have deployed, and have finished moving before
attempting to step on them. The running boards will resume normal
function once the blockage is cleared.
WARNING: Turn off the running boards before jacking or placing
any object under the vehicle. Never place your hand between the
extended running board and the vehicle. A moving running board may
cause injury.
Note: Do not use the running boards, front and rear hinge assemblies,
running board motors, or the running board under body mounts to lift
the vehicle when jacking. Always use proper jacking points.
Note: The running boards may operate slower in cooler temperatures.
Debris such as mud, dirt and salt may become trapped in the running
board mechanism, possibly leading to unwanted noise. If this occurs,
manually set the running boards to the deployed position and flush the
system (in particular the front and rear hinge arms) with a high-pressure
car wash wand.
The running boards automatically
move when the doors are opened to
assist entering and exiting the
vehicle.
Automatic Power Deploy
The running boards will extend down and out when the doors are
opened.
Automatic Power Stow
The running boards will return to the stowed position after a two second
delay when the doors are closed.
