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.

Instrument panel display
The computer manages the data display on the instrument panel relating to engine operation. This covers five
functions: the OBD warning light for European On Board Diagnostics (EOBD), pre-postheating, coolant temperature,
and Level 1 (non critical fault) and Level 2 (emergency stop) engine faults. These five functions are represented by
five warning lights or messages displayed by the trip computer.
Pre-postheating warning light
This warning light indicates that preheating is active.
Engine coolant temperature warning light
This warning light is used as an engine overheating indicator.
–In the event of overheating, it is up to the driver whether to stop the vehicle or continue driving.
OBD warning light
The OBD fault warning light is used to warn the driver of the presence of injection faults producing excessive
pollution or that the EOBD system is deactivated.
The injection computer requests illumination of the OBD warning light for a present fault only after three consecutive
driving cycles.
The visual check of the warning light when the power is switched on (automatic test procedure managed by
the instrument panel) is carried out by the injection computer. It lasts 3 seconds or until the engine starts for
the New Twingo and Kangoo 2.
If a confirmed OBD fault causes the OBD warning light to come on, there should be no flashing after the warning
light illumination test. The instrument panel will also display the message: Check emission control.
The gearbox computer, if fitted, may also request the illumination of this warning light.
Level 1 warning
If there is a minor fault, the computer may request a level 1 warning to be displayed. Usually, the instrument panel
switches on the SERVICE warning light and sends out a "Check the injection" message. Refer to the operation of the
instrument panel (see 83A, instrument panel). Note:
This warning light comes on only if the vehicle is EOBD approved.
Note:
The SERVICE warning light will come on if the instrument panel is configured as cruise control - speed
limiter present, but the function has not yet been detected by the injection computer.

Level 2 warning
If there is a major fault, the computer requests a level 2 warning to be displayed. Usually, the instrument panel
switches on the STOP warning light and sends out an "Injection fault" message. Refer to the operation of
the instrument panel (see 83A, instrument panel).
