170 SAFETY
Feedback To The Driver:
The instrument cluster has an HDC icon and the HDC
switch has an LED, which offers feedback to the driver
about the state HDC is in.
 The cluster icon and switch lamp will illuminate and
remain solid when HDC is enabled or activated.
This is the normal operating condition for HDC.
 The switch lamp will flash for several seconds then
extinguish when the driver pushes the HDC switch
when enable conditions have not been met.
The HDC switch is located within the Selec-Terrain knob in
the upper right position.
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a complete stop
while on an incline. If the driver releases the brake while
stopped on an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not apply the
throttle before this time expires, the system will release
brake pressure and the vehicle will roll down the hill as
normal.
The following conditions must be met in order for HSA to
activate:
 The feature must be enabled.
 The vehicle must be stopped.
 The parking brake must be off.
 The driver's door must be closed.
 The vehicle must be on a sufficient grade.
 The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE gear).
 HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK or NEUTRAL.
WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur, such
as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active driving
involvement. It is always the driver's responsibility to be
attentive to distance to other vehicles, people, and
objects, and most importantly brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always required
while driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a collision
or serious personal injury.
DISABLING AND ENABLING HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
 If disabling HSA using your instrument cluster display,
see page 70 for further information.
Ú
 If disabling HSA using Uconnect Settings, see
page 145 for further information.

TOWING WITH HSA
Hill Start Assist (HSA) will also provide assistance to
mitigate roll back while towing a trailer.
WARNING!
 If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resuming
acceleration, manually activate the trailer brake or
apply more vehicle brake pressure prior to releasing
the brake pedal.
 HSA is not a parking brake. Always apply the parking
brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK.
 Failure to follow these warnings can result in a colli-
sion or serious personal injury.
