checked as soon as possible.
Brake System It illuminates when you apply the
parking brake and the ignition is
on. If it illuminates when your
vehicle is moving, make sure the
parking brake is released. If the
parking brake is released, this
indicates low brake fluid level or the brake
system requires service. Have your vehicle
checked as soon as possible.
Note: Indicators may vary depending on
region.
Diesel Exhaust Fluid Illuminates when the diesel
exhaust fluid is low,
contaminated or the system
requires service. See What Is the
Selective Catalytic Reduction System
(page

HYBRID DISPLAY
INFORMATION
WHAT IS EV COACH
EV coach helps you get the most of your
vehicle's electrical driving and regenerative
braking capabilities.
HOW DOES EV COACH WORK
When accelerating or maintaining speed,
a blue or white solid bar displays. This
indicates vehicle power. A blue rectangular
box could also display that shows the
power level that the engine turns on at. When the power level displays in the
rectangular box, it is blue which indicates
you are in electric only operation.
When the power level displays outside of
the rectangular box, it is white which
indicates you are in hybrid operation.
When you are decelerating, either releasing
the accelerator pedal or applying the
brake, you see a green or white solid bar
which indicates the power being used to
slow your vehicle down. A green
rectangular box could also display that
shows the amount of power that can be
recaptured by the regenerative braking
system and returned to the high voltage
battery.
When the power level displays in the
rectangular box, it is green which indicates
that the regenerative braking system is
being used to slow down your vehicle and
return the maximum amount of energy to
the high voltage battery.
When the power level displays outside of
the rectangular box, it is white which
indicates both regenerative and
conventional braking systems are in use.
WHAT IS BRAKE COACH
The brake coach appears after the vehicle
has come to a stop. It coaches you to brake
in a manner that maximizes the amount
of energy returned through the
regenerative braking system.
The percent displayed is an indication of
the regenerative braking efficiency with
100% representing the maximum amount
of energy recovery. You can switch brake
coach on or off in the settings menu on
your touchscreen.

TRAIL CONTROL INDICATORS
- 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,
some situations may require you to press
the brake pedal to come to a complete
stop.
SWITCHING TRAIL ONE PEDAL
DRIVE ON AND OFF
