Feedback To The Driver
The instrument cluster has an H DC icon and the HDC
switch has an indicator light, which offers feedback to
the driver about the state HDC is in.
•
The cluster icon and switch ind icator light will illumi-
nate and remain on solid when HDC is enabled or
activated. This is the normal operating condition for
HDC.
•
The cluster icon and switch ind icator light will flash
for several seconds then extinguish when the driver
pushes the HDC switch but enable conditions are
not met.
•
The cluster icon and switch ind icator light will flash
for several seconds then extinguish when HDC dis-
ables due to excess speed.
•
The cluster icon and switch ind icator light will flash
when HDC deacti vates 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)
The HSA system 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 con-
tinue 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. (If the doors are
attached, then the door mu st be closed. If the doors
are detached then the driver's seat belt must be
buckled.)
•
The vehicle must be on a sufficient grade.
•
The gear select ion must match vehicle uphill d ir ec-
tion (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 t he transmis-
sion 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 d ist ance 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 co ntrol 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, refer to
page 201 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 trai ler 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 (P).
•
Failure to follow these warnings can result in a col-
lision or se rio us 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 dri ver interaction is
required.
