126 SAFETY
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 deactivated with the brake switch. If
so, there may not be enough brake pres-
sure 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 acti-
vate 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)
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 power to be applied to the wheel that is
not spinning. BLD may remain enabled even if
TCS and ESC are in a reduced mode.
Rain Brake Support (RBS)
Rain Brake Support (RBS) may improve braking
performance in wet conditions. 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
Rain Brake Support is active, there is no
notification to the driver and no driver
interaction is required.
Ready Alert Braking (RAB)
Ready Alert Braking (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 EBC will prepare the brake
system for a panic stop.
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 that TSC
cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
trailer tongue weight recommendations. Refer
to "Trailer Towing" in "Starting And Operating"
for more 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
