System Intervention
This is indicated by the flashing of the warning light on
the instrument panel, to inform the driver that the
vehicle is in critical stability and grip conditions.
Hill Start Assist (HSA)
This is an integral part of the ESC system and facilitates
starting on slopes, activating automatically in the fol-
lowing cases:
Uphill: vehicle stationary on a road with a gradient
higher than 5%, engine running, brake pressed and
transmission in neutral (N) or gear other than reverse
engaged.
Downhill: vehicle stationary on a road with a gradi-
ent higher than 5%, engine running, brake pressed
and reverse (R) gear engaged.
When setting off, the ESC system control unit maintains
the braking pressure on the wheels until the engine
torque necessary for starting is reached, or in any case
for a maximum of two seconds, allowing your right foot
to be moved easily from the brake pedal to the accel-
erator.
When the two seconds have elapsed, without starting,
the system is automatically deactivated, gradually re-
leasing the braking pressure. During this release stage,
the typical brake disengagement noise, indicating that
the vehicle is going to move imminently, can be heard.
NOTE:
HSA is not a parking brake; therefore, never leave the
vehicle without having engaged the parking brake,
turned the engine off and engaged first gear, so that
the vehicle is parked in safe conditions.
There may be situations on small gradients (less than
8%), with vehicle laden, in which the Hill Holder
system may not activate, causing a slight reversing
motion and increasing the risk of collision with
another vehicle or object. The driver is, in any case,
responsible for safe driving.
