216 SAFETY
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 (EBC) system will prepare the
brake system for a panic stop.
Rain Brake Support (RBS)
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 RBS is active, there is no
notification to the driver and no driver
interaction is required.
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 vehicle
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 vehicle torque to be applied to the
wheel that is not spinning. BLD may remain
enabled even if TCS and the Electronic Stability
Control (ESC) are in reduced modes.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a
trailer and follow the trailer tongue weight
recommendations Ú page 145.
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.
