WHAT IS REVERSE BRAKING
ASSIST
The system uses sensors on the rear of
your vehicle to detect a possible collision
and applies the brakes to either reduce the
damage from impact, or to assist in
avoiding the collision.
HOW DOES REVERSE
BRAKING ASSIST WORK
Reverse Braking Assist functions when in
reverse (R) and traveling at a speed of
1–
7 mph (1.5– 12 km/h).
If the system detects an obstacle behind
your vehicle, it provides a warning through
the rear parking aid or cross traffic alert
system.
REVERSE BRAKING ASSIST
PRECAUTIONS WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death. WARNING:
To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due
care and attention. Failure to take care
may result in a crash. WARNING: Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system. This
may cause reduced performance or false
alerts. WARNING:
Some situations and
objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types,
and pedestrians. Apply the brakes when
necessary. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Do not use the system
with accessories that extend beyond the
front or rear of your vehicle, for example
a trailer hitch or bike rack. The system is
not able to make corrections for the
additional length of the accessories.
The system only applies the brakes for a
short period of time when an event occurs.
Act as soon as you notice the brakes apply
in order to remain in control of the vehicle.
Note: Certain add-on devices around the
bumper or fascia may create false alerts.
For example, large trailer hitches, bicycle or
surfboard racks, license plate brackets,
bumper covers or any other device that may
block the normal detection zone of the
system. Remove the add-on device to
prevent false alerts.
Note: The system does not react to small
or moving objects, particularly those close
to the ground.
Note: The system does not operate during
hard acceleration or steering.

(If Equipped)

Note:
If your vehicle sustains damage to
the bumper or fascia leaving it misaligned
or bent, it could alter the sensing zone
causing inaccurate measurement of
obstacles or false alerts.
Note: Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.
Note: When you connect a trailer, the
system may detect the trailer and provide
an alert, or the system turns off. If the
system does not turn off, switch the system
off manually after you connect the trailer.
Note: You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.

WHAT IS HILL START ASSIST
Hill Start Assist makes it easier for you to
pull away when your vehicle is on a slope
without using the parking brake.
HOW DOES HILL START
ASSIST WORK
When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake
pedal to the accelerator pedal. The brakes
release when the engine has developed
sufficient torque to prevent your vehicle
from rolling down the slope.

replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.

controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system will turn
off if a malfunction is apparent. Failure
to take care may result in the loss of

- RAPTOR
TRAIL ONE PEDAL DRIVE (IF
EQUIPPED)
WHAT IS TRAIL ONE PEDAL DRIVE
Trail one pedal drive allows you to
accelerate and brake using only the
accelerator pedal. The system assists
when driving through difficult off-road
terrain. Pressing the accelerator pedal
down accelerates your vehicle and
releasing pressure on the accelerator
pedal, with your foot still on the pedal,
slows your vehicle down. Releasing the
accelerator pedal may allow your vehicle
to come to a complete stop, some
situations may require you to press the
brake pedal to come to a complete stop.
TRAIL ONE PEDAL DRIVE
PRECAUTIONS WARNING:
This system is an extra
driving aid. It does not replace your
attention and judgment, or the need to
apply the brakes. This system does NOT
automatically brake your vehicle. If you
fail to press the brake pedal when
necessary, you may collide with another
vehicle.
Shifting into drive (D) or reverse (R) does
not cause the vehicle to move.
You can press the brake pedal to increase
braking. This does not turn the system off. Trail one pedal drive could apply the
parking brake when your vehicle is not
moving and not in park (P).
Note:
Always check the transmission
selection before accelerating.
Note: Only use trail one pedal drive on
slippery or loose surfaces. Using trail one
pedal drive on dry, hard surfaces could
produce some vibration, driveline bind up
and potential excessive tire and vehicle
wear.
TRAIL ONE PEDAL DRIVE
LIMITATIONS
Trail one pedal drive is unavailable when
any of the following occur:
• Your vehicle is not in four-wheel drive
high (4H) or four-wheel drive low (4L)
modes.
• Using cruise control.
• Using trail control.
• You exceed
30 mph (48 km/h).
Releasing the accelerator pedal may allow
your vehicle to come to a complete stop,

WHAT IS HILL DESCENT
CONTROL
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions.
HOW DOES HILL DESCENT
CONTROL WORK
Hill descent control can maintain vehicle
speeds on downhill slopes between
2
– 20 mph (3– 32 km/h). Above 20 mph
(32 km/h), the system remains on but the
descent speed cannot be set or
maintained.
Note: The system does not function below
2 mph (3 km/h)
.
The system requires a cool down interval
after a period of sustained use. Hill descent
control provides a warning in the message
center and a tone sounds when the system
is about to disengage for cooling. At this
time, manually apply the brakes as needed
to maintain descent speed.
Note: The amount of time that the system
can remain active before cooling varies with
conditions.
HILL DESCENT CONTROL
PRECAUTIONS WARNING:
The system does not
control speed in low traction conditions
or extremely steep slopes. The system
is designed to be an aid and does not
relieve you of your responsibility to drive
with due care and attention. Failure to
follow this instruction could result in
personal injury. WARNING:
Hill descent control
cannot control descent in all surface
conditions and circumstances, such as
ice or extremely steep grades. Hill
descent control is a driver assist system
and cannot substitute for good judgment
by the driver. Failure to do so may result
in loss of vehicle control, crash or serious
injury. WARNING:
The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake and shift the transmission
into park (P) for automatic transmission
or first gear for manual transmission.
SWITCHING HILL DESCENT
CONTROL ON AND OFF Press the button on the
instrument panel. A light
illuminates and a tone sounds
when the system is active.
SETTING THE HILL DESCENT
SPEED
To increase or decrease the descent speed,
press the accelerator or brake pedal, or use
the SET
+ and SET - buttons on the
steering wheel. Once you reach the
preferred speed remove your feet from the
pedals.
HILL DESCENT CONTROL
