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.
The system may reduce engine power and
apply the brake of the appropriate wheel(s) to
counteract the sway of the trailer. TSC will
become active automatically once an exces-
sively swaying trailer is recognized. Note that
TSC cannot stop all trailers from swaying. Al-
ways use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in this section 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” mode.
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.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver
when starting a vehicle from a stop on a hill.
HSA will maintain the level of brake pressure
the driver applied for a short period of time after
the driver takes their foot off of the brake pedal.
If the driver does not apply the throttle during
this short period of time, the system will release
brake pressure and the vehicle will roll down the
hill. The system will release brake pressure in
proportion to the amount of throttle applied as
the vehicle starts to move in the intended direc-
tion of travel.
HSA Activation Criteria
The following criteria must be met in order for
HSA to activate:
•
Vehicle must be stopped.
•
Vehicle must be on a 6% (approximate)
grade or greater hill.
•
Gear selection matches vehicle uphill direc-
tion (i.e., vehicle facing uphill is in forward
gear; vehicle backing uphill is in REVERSE
gear).
HSA will work in REVERSE and all forward
gears when the activation criteria have been
met. The system will not activate if the vehicle is
placed in NEUTRAL or PARK.
WARNING!
There may be situations on minor hills with a
loaded vehicle, or while pulling a trailer,
when the system will not activate and slight
rolling may occur. This could cause a colli-
sion with another vehicle or object. Always
remember the driver is responsible for brak-
ing the vehicle.
Towing With HSA
HSA will provide assistance when starting on a
grade when pulling a trailer.
