Dynamic Steering Torque (Dst) - Fiat 500L 2015 Owner's Manual

264 STARTING AND OPERATING
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
• Vehicle must be stopped.
• Vehicle must be on a 5% grade or greater hill.
• Gear selection matches vehicle uphill direction (i.e.,
vehicle in NEUTRAL (manual transmission), vehicle
facing uphill is in forward gear; vehicle backing uphill
is in REVERSE gear).
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 brak-
ing the vehicle.
Disabling/Enabling HSA
If you wish to turn the HSA system on or off, it can be done
using the Customer Programmable Features in the Elec-
tronic Vehicle Information Center (EVIC). Refer to "Elec-
tronic Vehicle Information Center (EVIC)" in "Understand-
ing Your Instrument Panel" for further information.

Dynamic Steering Torque (DST)

The DST function uses the integration of the ESC system
with the electric power steering to increase the safety
level of the whole car.
In critical situations (understeering, oversteering, brak-
ing with different grip conditions), through the DST
function the ESC system controls the steering to imple-
ment an additional torque contribution on the steering
wheel, to suggest the most correct manoeuvre to the
driver.
