SAFETY 151
The following conditions must be met in order
for HSA to activate:
The feature must be enabled
The vehicle must be stopped
Park brake must be off
Driver door must be closed. (If the doors are
attached, then the door must be closed. If the
doors are detached then the driver's seatbelt
must be buckled)
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 (R) gear)
HSA will work in REVERSE gear and all
forward gears. The system will not activate if
the transmission is in PARK (P) or NEUTRAL
(N). For vehicles equipped with a manual
transmission, 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, refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Ready Alert Braking (RAB)
Ready Alert Braking (RAB) may reduce the time
required to reach full braking during emergency
braking situations. It anticipates when an emer-
gency braking situation may occur by moni-
toring how fast the throttle is released by the
driver. The EBC will prepare the brake system
for a panic stop.
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.
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 (P).
Failure to follow these warnings can result in
a collision or serious personal injury.
