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 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. For
vehicles equipped with a manual transmis -
sion, if the clutch is pressed, HSA will remain
active.
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
Ú
page 111.

If disabling HSA using Uconnect Settings, see
Ú
page 258.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
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 involve -
ment. 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 vehi -
cle. Failure to follow these warnings can
result in a collision or serious personal injury.
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 pres -
sure 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 acti -
vate 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 trans -
mission in PARK.

Failure to follow these warnings can result
in a collision or serious personal injury.
