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.

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.

PARKING AID PRECAUTIONS
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
fluorescent lamps, 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:
The system may not
detect small or moving objects,
particularly those close to the ground. WARNING:
The parking aid system
can only assist you to detect objects
when your vehicle is moving at parking
speeds. To help avoid personal injury you
must take care when using the parking
aid system. WARNING:
The system may not
function if the sensor is blocked. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible. Note:
If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts.
When you connect a trailer to your vehicle,
the rear parking aid detects the trailer and
provides an alert. Disable the parking aid
when you connect a trailer to prevent the
alert.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts, for example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that could block the normal detection zone
of the parking aid system. Aftermarket spare
tires or spare tire covers mounted to the rear
tailgate could cause false alerts from the
park aid system. Remove the add-on device
to prevent false alerts.
Note: Keep the sensors 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: When using a programmed MyKey,
you cannot switch the parking aids off. See
MyKey ™
(page 98).
REAR PARKING AID
(IF EQUIPPED)
WHAT IS THE REAR PARKING AID

HOW DOES ADAPTIVE CRUISE
CONTROL WITH STOP AND GO
WORK
Adaptive cruise control with stop and go
uses radar and camera sensors to maintain
a set gap between your vehicle and the
vehicle in front of you while following it to
a complete stop. Stop and go can also be
set to follow a vehicle directly in front of
you and adjust the set speed, while you are
at a complete stop.
