DESCRIPTION - CRUISE CONTROL - Alfa Romeo 159 1.9 JTD 8V Da 01/06
The Cruise Control function - constant speed governor - allows the driver to drive the car at a constant speed without pressing the accelerator pedal.The function is managed by the engine control unit. It receives commands from a Cruise Control lever on the left of the steering wheel beneath the stalk switch unit.The function is engaged by turning the wheel (Cruise symbol: Cruise activated; "O": Cruise deactivated). Moving the lever memorizes an increase (+) or decrease (-) in the speed; this remains stored in the memory and can be restored at any time by pressing the RES (resume) button.The function is automatically deactivated:- by pressing the brake pedal;- by pressing the clutch pedal;- by turning the wheel to "O";- by turning off the engine.In such cases, the last speed achieved is stored and can be recalled by pressing the RES button.The system also deactivates at speeds below the minimum permitted speed (about 30 km/h)With the system activated, the warning light in the instrument panel comes on, connected via the CAN to the engine management control unit.For more details
