The electronically controlled Cruise Control system makes it possible to drive the vehicle at the desired speed without pressing the accelerator pedal.This makes driving on motorways less tiring, especially on long journies, because the speed memorized is maintained automatically.769The device can only be switched on at speeds above 40 km/h or in 4th or 5th gear.768The speed regulator should only be activated when traffic and route conditions allow a constant speed to be safely maintained for a sufficiently long stretch.The function is managed by the engine control unit. This receives commands from a Cruise Control lever on the left of the steering wheel.The function is engaged by turning the wheel (ON).When a speed is set ( SET + , SET - ), the setting is saved and may be called up at any time ( RCL ).If necessary, the speed setting may be over-ruled by pressing the accelerator pedal (e.g. when overtaking); the system returns to the stored speed when the pedal is released.The function deactivates automatically:- by pressing the brake pedal;- by pressing the clutch pedal;- by turning the wheel to OFF;- by turning off the engine.In such cases, the last speed achieved is stored and can be recalled by pressing the RCL button.The system also deactivates at speeds below the minimum permitted speed (about 30 km/h).The Cruise Control system control lever is incorporated in the steering column switch unit (Steering wheel node): the activation, deactivation, etc. information is sent to the Body Computer via the CAN.With the system activated, the milometer warning lights node warning light is lit up.767There is a second "redundant" switch located on the brake pedal, used by the engine management control unit, in particular, for the Cruise Control function.The "basic" switch (I030) is the "normally open" type (when the pedal is pressed, the switch closes), whilst the "redundant" switch (I035) is the "normally closed" type (when the pedal is pressed, the switch contact opens): the system checks the consistency of the "pedal pressed" information in this way.

The Cruise Control function is managed by the engine control unit M010.All cruise control function controls are supplied by steering wheel node control unit M093 (pins 1, 3 connector A) to body computer node M001 (pins 5, 3 connector G respectively) and then from this node (pins 8 and 10 connector D) to engine control unit M010 (pins A3 and A4 connector A). The signal is sent via the CAN network.Body computer M001 (pin 11 connector B and pin 1 connector G) supplies steering wheel node control unit M093 (pin 5 connector A and pin 4 connector D respectively) via two lines, of which only the second is protected by fuse F04.The command from the steering wheel node control unit M093 activates the system and communicates the constant speed to be maintained.The system is disengaged as soon as brake pedal I030 or clutch pedal I031 is pressed (on versions with a manual gearbox only); if the accelerator pedal K055 is pressed, the system is disengaged temporarily and reset when the pedal is released.Brake pedal I030 is connected (pin 2) to body computer node M001 (pin 4 connector B) and supplementary fuse box B098 (pin G31 connector B). This latter conection is made via a line protected by fuse F31 located inside the control unit.Accelerator pedal K055 (pins 1, 2, 3, 4) is connected to engine control unit M010 (pin G3, H3, C2, G2 connector A respectively) and is equipped with two built-in potentiometers: a main one and one safety one.Clutch pedal switch I031 is interfaced on one side (pin 2) with engine control unit M010 (pin E3 connector A) and on the other (pin 1) with body computer node M001 (pin 9 connector B).The safety switch on brake pedal I035 is also connected (pin 2) to control unit M010 (pin E4 connector A) and receives power at pin 1.Switches I031 and I035 supply the cruise control activation signal to control unit M010.The "redundant" switch I035 is the "normally closed" type (when the pedal is pressed, the switch contact opens): the system checks the consistency of the "pedal pressed" information in this way.Warning light activation is controlled by odometer warning light node M140, which communicates via CAN line (pins 2 and 5) with instrument panel E050 (pins 6 and 12) and body computer node M001 (pins 8 and 10 connector D).The latter (M001 pin 6 connector D) supplies power to both components E050 (pin 13) and M140 (pin 4).
