•
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the 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 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 78 for further information.
•
If disabling HSA using Uconnect Settings, see
page 165 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.
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 system will prepare
the brake system for a panic stop.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS
may apply brake pressure to the spinning wheel(s)
and/or reduce engine power to provide enhanced
acceleration and stability. A feature of the TCS, Brake
Limited Differential (BLD) functions similarly to a limited
slip differential and controls the wheel spin across a
driven axle. If one wheel on a driven axle is spinning
faster than the other, the system will apply the brake of
the spinning wheel. This will allow more engine power
to be applied to the wheel that is not spinning. BLD may
remain enabled even if TCS and Electronic Stability
Control (ESC) are in reduced modes.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway.
NOTE:
TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer
tongue weight recommendations
page 152.
When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine power
may be reduced and you may feel the brakes being
applied to individual wheels to attempt to stop the
trailer from swaying. TSC is disabled when the ESC sys-
tem is in the “Partial Off” or “Full Off” modes.
WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
