Cruise control - speed limiter (CC / SL) management
When activated, the cruise control function maintains the vehicle at a preselected speed, regardless of the
driving conditions encountered. Using the control buttons, the driver can increase or reduce the speed of the vehicle.
The cruise control function can be deactivated either using the control buttons, or by switching off the cruise control
function selector switch or when system events are detected such as the brake or clutch pedal being depressed,
or when system errors are detected such as an inconsistent vehicle speed or excessive vehicle deceleration.
The cruise control function can also be temporarily overridden when the driver wants to resume control of
the vehicle and exceed the selected cruising speed by pressing the accelerator pedal, which causes the controlled
fuel flow to be exceeded. The cruising speed is resumed when the driver releases the accelerator pedal.
It is possible to reactivate cruise control and to return to the last cruising speed after the function has been
deactivated for whatever reason, during the same cycle of use (computer supply voltage not cut off). The vehicle will
then attempt to return to the cruising speed using a controlled vehicle acceleration rate.
When activated (using the selection switch), the vehicle speed limiter function limits the vehicle speed to
a preselected value.
The driver controls the vehicle in the normal way using the accelerator pedal until the limit speed is reached. If an
attempt is made to exceed this speed, the system will ignore the pedal request and will limit the vehicle speed,
provided that the driver continues to depress the accelerator pedal.
As with the cruise control function, the limit speed can be altered using the control buttons by pressing briefly or by
pressing and holding (pressing and holding not active on Kangoo 2).
For safety reasons, the limit speed can be exceeded by depressing the accelerator pedal beyond the pedal position
limit value. The vehicle speed will then be totally controlled by the pedal until the speed falls back below the cruising
speed when the speed limiter function will once again be reactivated.
The driver has the following controls for the cruise control - speed limiter function:
–accelerator pedal,
–brake pedal,
–clutch pedal (not for sequential gearbox),
–function selector switch, used to select cruise control or speed limiter operating mode,
–activation switch on the steering wheel,
–required speed adjustment switch on the steering wheel.

STATUS DEFINITION"PRESENT": The fast idle speed request is present.
"ABSENT": The fast idle speed request is not present.
NOTESSpecial notes:
The idle speed setpoint is dependent on:
–the coolant temperature,
–the emission control programs,
–air conditioning requirements,
–the electrical consumers,
–the battery voltage,
–the gear engaged.
–use of command SC041 "Changing commercial vehicle idle speed" (Kangoo 2)
Conformity check with engine stopped, ignition on or engine running
PRESENTStatus is "PRESENT" when there is an engine load:
–inconsistency between the positions of the brake and accelerator pedals,
–coolant temperature < 80
°C or > 89 °C,
–heating and air conditioning system deactivated,
–with electrical consumers,
–the battery voltage is incorrect.
–or after running command SC041 "Changing commercial vehicle idle speed"
(Kangoo 2)
ABSENTStatus is "ABSENT" when there is no engine load:
–coolant temperature = 80
°C,
–heating and air conditioning system deactivated,
–without electrical consumers,
–the battery voltage is correct.

STATUS 2Brake pedal depressed
The cruise control function is deactivated when the brake pedal is depressed.
Status ET415 becomes STATUS 2 when driving with cruise control active (ET042
Cruise control / Speed limiter: CRUISE CONTROL) and the brake pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 2 without pressing the brake pedal, consult the
interpretation of statuses ET704 and ET705 Brake contact No. 1 and No. 2.
STATUS 3Clutch pedal depressed
Manual gearbox ONLY.
The cruise control function is deactivated when the gearbox is not coupled to the engine
(clutch pedal depressed).
Status ET415 becomes STATUS 3 when driving with cruise control active (ET042
Cruise control/speed limiter: CRUISE CONTROL) and the clutch pedal is depressed.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ001
"Fault memory".
If status ET415 becomes STATUS 3 without the clutch pedal being depressed, consult
the interpretation of status ET405 Clutch pedal.
If the vehicle is fitted with automatic transmission:
Test the multiplex network: check the configuration of the multiplex network in relation to
the vehicle's technical specification, especially the configuration of the automatic
transmission computer (see 88B, Multiplexing).
