VDC SYSTEM

GETTING
(Vehicle Dynamics Control)
TO KNOW
YOUR CAR
This is an electronic system that controls vehicle stability in the
event of tyre grip loss, helping maintain directional control. The sys-
tem is capable of recognising potentially dangerous situations in
terms of the stability and intervenes automatically on the brakes
SAFETY
in a differentiated manner for the four wheels in order to provide
a stabilizing torque.
The VDC, in turn, includes the following systems:

❍ Hill Holder
AND DRIVING
❍ ASR
❍ Brake Assist
❍ MSR

EMERGENCY
❍ "ELECTRONIC Q2" ("E-Q2")

HILL HOLDER SYSTEM
This system is an integral part of the VDC system and it is provided
to facilitate starting on slopes.
It is activated automatically in the following instances:
❍ uphill: car standing on a road with a gradient of more than 5%,
engine on, brake pedals pressed and gearbox in neutral or gear
(other than reverse) engaged;
❍ downhill: car at a standstill on a road with a gradient higher
than 5%, engine running, brake pedal pressed and reverse gear
engaged.
When setting off the VDC system control unit maintains the brak-
ing pressure at the wheels until the engine torque required for de-
parture is reached or for approximately 2 seconds, allowing your
right foot to be moved easily from the brake pedal to the acceler-
ator.
If the car does not start off after this time, the system will deacti-
vate automatically by gradually releasing the brake force. A noise
may be heard: this means that the car is about to start moving.
IMPORTANT the Hill Holder system should not be used as a hand-
brake. Do not leave the vehicle without having engaged the hand-
brake, switched off the engine and engaged a gear.
