252 SAFETY
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 direc-

tion (i.e., vehicle facing uphill is in forward gear;
vehicle backing uphill is in REVERSE (R) gear).
HSA will work in REVERSE gear and all forward

gears. The system will not activate if the trans-
mission is in PARK (P) or NEUTRAL (N). For vehi-
cles equipped with a manual transmission, if
the clutch is pressed, HSA will remain active.
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 Ú page 97 for further information.
If disabling HSA using Uconnect Settings, see

Ú page 203 for further information.
Towing With HSA
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 accel-
eration, 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

collision or serious personal injury.
