appropriate wheel(s) to counteract the sway of the trailer.
TSC will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired to activate. 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 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 "ESC Partial Off" or "ESC Full Off"
modes.
TSC is only active in the default "ESC On" mode. TSC
can be disabled by pressing the "ESC Off" switch and
entering "ESC Partial Off" mode. It is not active in the
"ESC Partial Off" or "ESC Full Off" modes. Refer to the
ESC portion of this section for an explanation of the
different ESC operating modes.
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
