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:
Do not use trail turn assist on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive line, or braking components.
Trail turn assist is only intended for slippery,
or loose surfaces.
You may hear noise from the anti-lock
brake system while trail turn assist is
active. This is normal operation.
TRAIL TURN ASSIST
LIMITATIONS

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.

The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle image does
not illuminate if the system does not
detect a vehicle in front of you.
Detection Issues Can Occur:
When driving on a different line
than the vehicle in front.
A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
B
There may be issues with the
detection of vehicles in front
when driving into and coming out
of a bend or curve in the road.
C
In these cases, the system may brake late
or unexpectedly. If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detection.
Optimal system performance requires a
clear view of the road by the windshield
camera.
Optimal performance may not occur if:
•
The camera is blocked.
• There is poor visibility or lighting
conditions.
• There are bad weather conditions.
