Operation
OperationThe DSC button is in the centre console switch cluster (SZM)
The DSC button has 2 functions that can be set by pressing the button for different lengths of time when ACC requires deceleration, DSC responds by applying the disc brakes on all four wheels (maximum rate of deceleration 2.5 mIs2) when the car is on a decent with the speed preset by the driver, ECO automatically applies the brakes in order to keep the cars speed constant at the preset value.
When the brakes are applied automatically in this way, the brake lights are activated in accordance with the requirements of road-safety legislation. The light module does not activate the brake lights unless the vehicle's rate of deceleration is greater than 1 mIs2. This prevents the brake lights from flickering on and off.
Runflat Indicator (RPA)
RPA is not a function of the dynamic stability control system.
RPA is integrated into the DSC control unit as the four wheel speed signals are required for this function.
By comparing the speed signals for all four wheels, the system detects differences in rolling circumference at the individual wheels. This enables the system to recognise a sudden loss of pressure in the tyres.
