WARNING! (Continued)
sibility to be attentive to distance to other
vehicles, people, and objects, and most im-
portantly brake operation to ensure safe op-
eration of the vehicle under all road condi-
tions. Your complete attention is always
required while driving to maintain safe control
of your vehicle. Failure to follow these warn-
ings can result in a collision or serious per-
sonal 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
display, refer to “Instrument Cluster Display”
in “Getting To Know Your Instrument Panel”
for further information.
•
If disabling HSA using Uconnect Settings,
refer to “Uconnect Settings” in “Multimedia”
for further information.
For vehicles not equipped with an instrument
cluster display, perform the following steps:
1. Center the steering wheel (front wheels
pointing straight forward).
2. Shift the transmission into PARK.
3. Apply the parking brake.
4. Start the engine.
5. Rotate the steering wheel slightly more than
one-half turn to the left.
6. Push the “ESC Off” button located in the
lower switch bank below the climate control
four times within 20 seconds. The “ESC Off
Indicator Light” should turn on and turn off
two times.
7. Rotate the steering wheel back to center and
then an additional slightly more than one-half
turn to the right.
8. Turn the ignition to the OFF mode and then
back to ON. If the sequence was completed
properly, the “ESC Off Indicator Light” will
blink several times to confirm HSA is dis-
abled.
9. Repeat these steps if you want to return this
feature to its previous setting.
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 acti-
vated 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 acceleration, manu-
ally 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 trans-
mission in PARK.
•
Failure to follow these warnings can result
in a collision or serious personal injury.
Traction Control System (TCS)
This system 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 similar 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 torque to be applied to
the wheel that is not spinning. BLD may remain
enabled even if TCS and ESC are in a reduced
mode.
