HILL HOLDER SYSTEM
This system is an integral part of the ESC system
and facilitates starting on slopes.
It is activated automatically in the following
instances:
❒ uphill: car stationary on a road with a gradient
higher than 5%, engine running, brake pressed
and gearbox in neutral or gear (other than
reverse) engaged;
❒ downhill: car stationary on a road with a
gradient higher than 5%, engine running, brake
pressed and reverse gear engaged.
When setting off, the ESC system control unit
maintains braking pressure on the wheels until the
torque required for starting is reach or, in any
case, for a maximum of 2 seconds so that the right
foot can be moved easily from the brake pedal to
the accelerator pedal.
When 2 seconds have elapsed, without any
departure having taken place, the system is
automatically deactivated, gradually releasing the
braking pressure. During this release stage, a
typical mechanical brake release noise can
be heard, indicating that the car is about to move.
IMPORTANT The Hill Holder system is not a
parking brake, therefore do not leave the vehicle
without activating the handbrake, switching
off the engine and engaging first gear.
ASR SYSTEM (AntiSlip Regulation)
It is an integral part of the ESC system. It
automatically operates in the event of one or both
drive wheels slipping, loss of grip on wet roads
(aquaplaning) and acceleration on slippery, snowy
or icy roads, etc…
Depending on the slipping conditions, two
different control systems are activated:
❒ if the slipping involves both drive wheels, the
ASR intervenes reducing the power transmitted
by the engine;
❒ if the slipping only involves one of the drive
wheels, it intervenes automatically braking
the wheel that is slipping.
Activation/deactivation of the ASR system
The ASR system activates automatically each time
the engine is started.
Whilst driving, the ASR can be deactivated and
subsequently activated again by pressing the ASR
OFF button fig. 68.
On some versions, the intervention of the system is
indicated by a message shown on the display.
When the system is not active, the LED on the
button ASR OFF turns on and, on some versions,
a message appears on the display.
When the ASR is deactivated whilst driving, the
next time the car is started the ASR is
automatically activated.
