A few definitions…
Range
(miles or km) This indicates the distance which can still be travelled with the fuel remaining in the tank in relation to the average fuel consumption over the last few miles (kilometres) travelled.
Current fuel consumption
(mpg or l/100 km or km/l)
This is the average fuel consumption duringthe last few seconds.
Average fuel consumption
(mpg or l/100 km or km/l) This is the average fuel consumption sincethe last trip computer zero reset.
Average speed
(mph or km/h) This is the average speed calculated since the last trip computer zero reset (ignition on).
Distance travelled
(miles or km) This indicates the distance travelled since the last trip computer zero reset.
Stop & Start time counter
(minutes/seconds or hours/minutes)
If your vehicle is fitted with Stop & Star t, a time counter calculates the time spent in STOP mode during a journey. It resets to zero every time the ignition is
switched on with the key.
This value may vary following a change in the style of driving or the relief, resulting in a significant change inthe current fuel consumption.
If dashes are displayed continuously while driving in place of the digits, contact a CITROËN dealer.
This function is only displayed from 20 mph (30 km/h).
When the range falls below 20 miles (30 km),
dashes are displayed. After filling with at least 5 litres of fuel, the range is recalculated and is displayed when it exceeds 60 miles (100 km).
Distance remaining to destination
(miles or km) This is the distance remaining to be travelled to the final destination. It can be entered by the user. If the distance is not entered, dashes are displayed in place of the digits.

67Comfort
Digital air conditioning
The air conditioning operates when the engine is r unning, as well as in STOP mode with Stop & Start.
Automatic operation
1. Automatic "comfort" programme
Press the "AUTO" button. The "AUTO" symbol is displayed. We recommend that you use this mode. It provides optimised automatic control of all of the following functions: passenger compar tment temperature, air flow, air distribution and air intake, in accordance with the comfor t value that you have chosen. This system is designed to operate effectively in all seasons, with the windows closed.
For your comfor t, when the engine is switched off, the settings are retained until the engine is switched on again. To prevent too great a distribution of cold air when the engine is cold, the air flow will only reach its optimum level gradually.
2. Temperature adjustment
The value indicated on the display corresponds to a level of comfor t and not to a temperature in degrees Celsius or Fahrenheit.
On entering the vehicle, if the interior is very cold or hot, there is no need to change the value displayed in order to reach the required level of comfor t. The system corrects the temperature difference automatically and as quickly as possible.
Press the "" and "" buttons to change this value. A setting around the value 21 enables optimum comfor t to be obtained. However, depending on your requirements, a setting between 18 and 24 is usual.
3. Automatic "visibility" programme
The automatic comfor t programme may not be sufficient for rapid demisting or defrosting of the windscreen and side windows (humidity, several passengers, ice, etc.). In this case, select the automatic visibility programme. The button 3 indicator lamp comes on. The system automatically controls the air conditioning and the flow of air and provides optimum air distribution to the windscreen and side windows. It deactivates air recirculation 5 .
To exit this programme, press button 3 again or "AUTO" , the indicator lamp on the button goes off and "AUTO" is displayed.
With Stop & Star t, when demisting has been activated, the STOP mode is not available.

153Driving
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.

155Driving
The system is reactivated automatically at every new star t using the key.
Reactivation
This system requires a battery with a special specification and technology (reference numbers available from CITROËN dealers). Fitting a battery not listed by CITROËN introduces the risk of malfunction of the system. In the event of a malfunction with the system, the "ECO OFF" switch warning lamp flashes, then comes on continuously. Have it checked by a CITROËN dealer. In the event of a fault in STOP mode, the vehicle may stall. It is then necessary to switch off the ignition and star t the engine again using the key.
Operating fault Maintenance
Before working under the bonnet, deactivate the Stop & Star t system to avoid any risk of injury resulting from automatic operation of START mode.
The Stop & Star t system makes use of advanced technology. Specialist knowledge is needed for any work on the system, which can only be assured
by CITROËN dealers.
Press the "ECO OFF" switch again. The system is active again; this is confirmed
by the switch warning lamp going off, accompanied by a message on the screen.
