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 direction 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 direction (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 collision with another vehicle or object. Always
remember the driver is responsible for braking the
vehicle.
Towing With HSA
HSA will provide assistance when starting on a grade
when pulling a trailer.
