•
The cluster icon and switch light will flash for several
seconds, then extinguish when HDC disables due to
excess speed.
•
The cluster icon and switch light will flash when HDC
deactivates due to overheated brakes. The flashing
will stop and HDC will activate again once the
brakes have cooled sufficiently.
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.
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 sys-
tem 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 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 transmis-
sion is in PARK (P) or NEUTRAL (N).
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 dis-
play, see
page 95 for further information.
•
If disabling HSA using Uconnect Settings, see
page 182 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 deacti-
vated 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 park-
ing brake fully when exiting your vehicle. Also, be
certain to place the transmission in PARK.
•
Failure to follow these warnings can result in a col-
lision or serious personal injury.
Rain Brake Support (RBS)
RBS may improve braking performance in wet condi-
tions. 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 Controller (EBC) will pre-
pare the brake system for a panic stop.
