212 SAFETY
The ESC system will make buzzing or clicking

sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive
following the maneuver that caused the ESC
activation.
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 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 trans-
mission is in PARK or NEUTRAL. For vehicles
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 see Ú page 175.
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 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 trans-
mission in PARK.
Failure to follow these warnings can result

in a collision or serious personal injury.
