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 (P).
3. Apply the park 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
disabled.
9. Repeat these steps if you want to return this
feature to its previous setting.
Traction Control System (TCS)
The Traction Control System (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 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 Electronic Stability Control (ESC) are in
a reduced mode.
Trailer Sway Control (TSC)
Trailer Sway Control (TSC) uses sensors in the
vehicle to recognize an excessively swaying
trailer and will take the appropriate actions to
attempt to stop the sway. TSC will become
active automatically once an excessively
swaying trailer is recognized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to "Trailer Towing" in "Starting And
Operating" for further information.
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 system is in the "Partial
Off" or "Full Off" modes.
