WHAT IS TRAIL CONTROL -
RAPTOR
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.
Trail control lets you focus on steering
during low-speed and off-road use by
controlling your vehicle's acceleration and
braking to maintain the speed that you set.
You may hear a noise from the anti-lock
brake system pump motor when you use
the system. This is normal.
TRAIL CONTROL LIMITATIONS
- RAPTOR
Trail control is unavailable when any of the
following occur:
• Your vehicle speed is greater than
20 mph (32 km/h)
in two-wheel drive
high (2H) or four-wheel drive high (4H)
modes.
• Your vehicle speed is greater than
9 mph (15 km/h)
in four-wheel drive
low (4L) mode.
• Your vehicle speed is greater than
5 mph (8 km/h)
in reverse (R).
• The transmission is in park (P).
• The driver side door is open or your
seatbelt is off when the driver side door
is removed.
• Cruise control is on.
• Pro trailer backup assist is on. SWITCHING TRAIL CONTROL
ON AND OFF - RAPTOR Press the button.
The system switches off if you press the
button again or exceed 40 mph (64 km/h).

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,
some situations may require you to press
the brake pedal to come to a complete
stop.

WHAT IS TRAIL TURN ASSIST
Trail turn assist can reduce the turning
radius of your vehicle by applying the
brakes to the inside rear wheel in
low-speed, high steering-angle maneuvers.
TRAIL TURN ASSIST
PRECAUTIONS
Note:

brake system while trail turn assist is
active. This is normal operation.

FREQUENTLY ASKED QUESTIONS
Why does Trail Turn Assist not activate
after unlocking the rear differential? The rear differential may not be fully
disengaged. When possible, turn off
the rear axle locker while driving
straight before using trail turn assist.
If you are already in a tight turn when
you encounter this situation, driving
the vehicle for a short distance in
reverse could allow the differential to
fully disengage.

WHAT IS DRIVE MODE
CONTROL
Your vehicle has various drive modes that
you can select for different driving
conditions. Depending on the drive mode
that you select, the system adjusts various
vehicle settings.
HOW DOES DRIVE MODE
CONTROL WORK - RAPTOR
Selectable drive modes change various
electronic and mechanical settings within
your vehicle to tailor its performance and
driving characteristics to on-road or
off-road driving conditions. Steering feel
and effort, traction control, stability
control, chassis controls, powertrain
response, transmission shift points,
four-wheel driveline settings, exhaust noise
level and suspension dampening are
automatically altered to a pre-determined
setting depending upon the drive mode
that you select.
Note:
Your vehicle has diagnostic checks
that continuously monitor all systems for
proper operation. If a drive mode is
unavailable due to a system fault, your
vehicle defaults to normal mode and the
driveline remains in the four-wheel drive
setting that you last selected prior to the
system fault. Note:
Your vehicle reverts to normal mode
each time you start it. If you shut your
vehicle off in a drive mode other than
normal mode, at startup the instrument
cluster screen displays a pop-up asking if
you would like to return to your last used
drive mode. If you select yes to the pop-up,
your vehicle returns to the last selected drive
mode and the default four-wheel driveline
setting associated with that drive mode. If
you select no, your vehicle remains in normal
mode and the default four-wheel driveline
setting associated with that drive mode. If
you do not select yes or no, the pop-up
message times out, your vehicle remains in
normal mode, and the four-wheel driveline
setting remains in its last used setting.
Note: Do not use the electronic locking
differential on dry, hard surfaces. Doing so
produces excessive noise, vibration and
increases tire wear. See Electronic Locking
Differential (page 301).
