Stop & Start
The Stop & Star t system puts the engine temporarily on standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine restar ts automatically - START mode - as soon as you want to move off. The restar t takes place instantly, quickly and silently. Per fect for urban use, the Stop & Star t system reduce s fuel consumption and exhaust emissions as well as off ering the comfor t of silence when stationary.
Operation
Going into engine STOP mode
For your comfor t when parking, STOP mode is not available for a few seconds after coming out of reverse gear. STOP mode does not affect the functionality of the vehicle, such as braking, power steering, for example.
Never refuel with the engine in STOP mode; you must switch off the ignition with the key.
The "ECO" warning lamp comes on in the instrument panel and the engine goes into standby:
- with a manual gearbox , at speeds below 12 mph (20 km/h), put the gear lever into neutral, then release the clutch pedal,
A time counter calculates the sum of the periods in STOP mode during a journey. It rests itself to zero every time the ignition is switched on with the key.
STOP mode is not invoked when: - the driver's door is open, - the driver's seat belt is not fastened, - the vehicle has not exceeded 6 mph (10 km/h) since the last engine star t using the key, - the engine is needed to maintain a comfor table temperature in the passenger compar tment, - demisting is active, - some special conditions (battery charge, engine temperature, braking assistance, ambient temperature...) where the engine is needed to assure control of a system.
Special cases: STOP mode unavailable
The "ECO" warning lamp flashes for a few seconds, then goes off.
This operation is per fectly normal.

Going into engine START mode
The "ECO" warning lamp goes off and the engine star ts:
- with a manual gearbox , depress the clutch pedal,
Special cases: START invoked automatically
If the system has been deactivated in STOP mode, the engine restar ts immediately.
With a manual gearbox in STOP mode, if a gear is engaged without fully depressing the clutch pedal, a message is displayed asking you to depress the clutch pedal to restar t the engine.
At any time, press the "ECO OFF" switch to deactivate the system. This is confirmed by the switch warning lamp coming on accompanied by a message on the screen.
Deactivation
The "ECO" warning lamp flashes for a few seconds, then goes off; START is invoked automatically when: - the driver's door is open, - the driver's seat belt is not fastened, - the speed of the vehicle exceeds 15 mph (25 km/h) with a manual gearbox, - some special conditions (battery charge, engine temperature, braking assistance, ambient temperature...) where the engine is needed to assure control of a system.
The "ECO" warning lamp flashes, then goes off.
This operation is per fectly normal.

System which prevents the vehicle from exceeding the speed programmed by the driver. When the programmed speed limit is reached, pressing the accelerator pedal in the normal manner no longer has any effect. The speed limiter is switched on manually: it requires a programmed speed of at least 20 mph (30 km/h). The speed limiter is switched off by manual d offoperation of the control. The programmed speed can be exceeded temporarily by pressing the accelerator firmly. To return to the programmed speed, simply slow down to a speed below the programmed speed. The programmed speed remains in the memory when the ignition is switched off.
Speed limiter
The speed limiter cannot, in any circumstances, replace the need to respect speed limits, nor can it replace the need for vigilance and responsibility on the par t of the driver.
The controls of this system are grouped together on stalk A . 1. Speed limiter mode selection thumb wheel. 2. Value decrease button. 3. Value increase button. 4. Speed limiter on/off button.
Steering mounted controls
The programmed information is grouped together on the instrument panel screen. 5. Speed limiter on/off indication. 6. Speed limiter mode selection indication. 7. Programmed speed value.

Cruise control
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal. The cruise control is switched on manually: it requires a minimum vehicle speed of 25 mph (40 km/h), as well as the engagement of: - four th gear on a manual gearbox, - second gear on an automatic gearbox, in sequential mode, - position D on an automatic gearbox. The cruise control is switched off manually d offor by pressing the brake or clutch pedal or on triggering of the ESP system for safety reasons. It is possible to exceed the programmed speed temporarily by pressing the accelerator pedal. To return to the programmed speed, simply release the accelerator pedal. Switching off the ignition cancels any programmed speed value.

Programming
 Turn thumb wheel 1 to the "CRUISE"position: the cruise control mode is selected but is not switched on (PAUSE).  Set the programmed speed by
accelerating to the required speed, then press button 2 or 3 (e.g.: 70 mph (110 km/h)).
You can then change the programmed speed using buttons 2 and 3 : - by + or - 1 mph (km/h) = shor t press, - by + or - 5 mph (km/h) = long press, - in steps of + or - 5 mph (km/h) = maintained press.  Switch off the cruise control by pressing button 4 : the display confirms that it has been switched off (PAUSE).
 Switch the cruise control back on by pressing button 4 again.
Exceeding the programmed speed Intentional or unintentional exceeding of the programmed speed results in flashing of this speed on the display. Return to the programmed speed, by means of intent ional or unintentional deceleration of the vehicle, automatically cancels the flashing of the speed.
Leaving cruise control mode
 Turn thumb wheel 1 to the "0" position: the cruise control mode is deselected. The display returns to the distance recor der.
Operating fault
In the event of a cruise control malfunction, the speed is cleared resulting in flashing of the dashes. Have it checked by a CITROËN dealer.
When the cruise control is switched on, be careful if you maintain the pressure on one of the programmed speed changing buttons: this may result in a very rapid change in the speed of your vehicle. Do not use the cruise control on slippery roads or in heavy traffic. On a steep descent, the cruise control will not be able to prevent the vehicle from exceeding the programmed speed. To avoid any risk of jamming of the pedals: - ensure that the mat is positioned correctly, - never fit one mat on top of another.
