262 SAFETY
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 using the Uconnect
settings, see Ú page 171.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. It will periodically apply a small
amount of brake pressure to remove any water
buildup on the front brake rotors. It functions
when the windshield wipers are in LO or HI
speed. When RBS is active, there is no
notification to the driver and no driver
interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full
braking during emergency braking situations. It
anticipates when an emergency braking
situation may occur by monitoring how fast the
throttle is released by the driver. The Electronic
Brake Control (EBC) system will prepare the
brake system for a panic stop.
Selec-Speed Control (SSC) — If Equipped
SSC is intended for off-road driving in
4WD Low only. SSC maintains vehicle
speed by actively controlling engine
torque and brakes.
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 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.
