SAFETY 291
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
display, see Ú page 104.
If disabling HSA using Uconnect Settings, see
Ú page 236.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
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
Traction Control System (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.
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 accel-
eration, 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.
Failure to follow these warnings can result in a
collision or serious personal injury.
