2010 Citroen DS3 fuel

Rear screen demist - defrost
The control button is located on the heating or air conditioning system control panel.
Switching on
The rear screen demisting/defrosting can only operate when the engine is running.  Press this button to demist /defrost the rear screen and (depending on version) the door mirrors. The indicator lamp associated with the button comes on.
Switching off
The demisting/defrosting switches off automatically to prevent an excessive consumption of current.  It is possible to stop the demisting/defrosting operation before it is switched off automatically by pressing the button again. The indicator lamp associated with the button switches off.  Switch off the demisting/defrosting of the rear screen and door mirrors as soon as appropriate as lower current consumption results in reduced fuel consumption.
If the engine is switched off before the demisting/defrosting is switched off automatically, demisting/defrosting will resume next time the engine is switched on.

Fuel tank Fuel tank capacity: approximately 50 litres (petrol) or 48 litres (Diesel).
Low fuel level
Filling
A label affixed to the inside of the flap reminds you of the type of fuel to be used depending on your engine. Additions of fuel must be of at least 5 litres, in order to be taken into account by the fuel gauge.
The key cannot be removed from the lock until the cap is refitted. Opening the filler cap may create a noise caused by an inrush of air. This vacuum is entirely normal, resulting from the sealing of the fuel system.
To fill the tank safely:  the engine must be switched off, open the fuel filler flap,  inser t the key in the cap, then turn it to the left,
 remove the cap and hook it onto the clip located on the inside of the flap,  fill the tank, but do not continue after the 3rd cut- off of the pump ; this could cause malfunctions.
When you have filled the tank:  put the cap back in place,  turn the key to the right, then remove it from the cap,  close the flap.
When the fuel tank minimum level is reached this warning lamp comes on
on the instrument panel. When it first comes on there remains approximately 5 litres of fuel in the tank. You must refuel as soon as possible to avoid running out of fuel. If you run out of fuel (Diesel), refer also to the "Checks" section.
With Stop & Star t, never refuel with the system in STOP mode; you must switch off the ignition with the key.

Quality of the fuel used for
petrol engines
The petrol engines are per fectly compatible with E10 type petrol biofuels (containing 10 % ethanol), conforming to European standards EN 228 and EN 15376. E85 type fuels (containing up to 85 % ethanol) are reser ved exclusively for vehicles marketed for the use of this type of fuel (BioFlex vehicles). The quality of the ethanol must comply with European standard EN 15293. For Brazil only, special vehicles are marketed to run on fuels containing up to 100 % ethanol (E100 type).
Quality of the fuel used for
Diesel engines
The Diesel engines are per fectly compatible with biofuels which conform to current and future European standards (Diesel fuel which complies with standard EN 590 mixed with a biofuel which complies with standard EN 14214) available at the pumps (containing up to 7 % Fatty Acid Methyl Ester). The B30 biofuel can be used in cer tain Diesel engines; however, this use is subject to strict application of the special ser vicing conditions. Consult a CITROËN dealer. The use of any other type of (bio)fuel (vegetable or animal oils, pure or diluted, domestic fuel...) is strictly prohibited (risk of damage to the engine and fuel system).

Manual operation
D disappears and the gears engaged appear in succession on the instrument panel. In the event of the engine labouring or over-revving, the gear selected flashes for a few seconds, then the actual gear engaged is displayed.
It is possible to change from position D(automatic) to position M (manual) at any time. When the vehicle is stationary or moving very slowly, the gearbox selects gear M1automatically. The spor t and snow programmes do not operate in manual mode.
Invalid value during manual operation
 Select position M for sequential changing of the four gears.  Push the lever towards the + sign to change up a gear.  Pull the lever towards the - sign to change down a gear. It is only possible to change from one gear to another if the vehicle speed and engine speed permit; other wise, the gearbox will operate temporarily in automatic mode.
This symbol is displayed if a gear is not engaged correctly (selector between two positions).
Stopping the vehicle
Before switching off the engine, you can engage position P or N to place the gearbox in neutral. In both cases, apply the parking brake to immobilise the vehicle.
When the ignition is on, the lighting of this warning lamp, accompanied by an audible signal and a message on the multifunction screen, indicates a gearbox malfunction. In this case, the gearbox switches to back-up mode and is locked in 3rd gear. You may feel a substantial knock when changing from P to R RRand from N to R . This will not cause any damage to the gearbox. Do not exceed 60 mph (100 km/h), local speed restrictions permitting. Contact a CITROËN dealer as soon as possible.
Operating fault
If the lever is not in position P , Pwhen the driver's door is opened or approximately 45 seconds after the ignition is switched off, a message appears in the multifunction screen.  Return the lever to position P ; the
message disappears.
There is a risk of damage to the gearbox: - if you press the accelerator and brake
pedals at the same time, - if you force the movement of the gear lever from the P position to another
position when the battery is flat.
To reduce fuel consumption when at a prolonged standstill with the engine running (traffic jam...), put the gear lever in the N position and apply the parking brake.

157Driving
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.

Closing
Running out of fuel
(Diesel)
If your vehicle is fitted with an HDI engine, the fuel system must be primed if you run out of fuel. This system consists of a priming pump and a transparent pipe under the bonnet.
 Fill the fuel tank with at least five litres of Diesel.  Open the bonnet.  Depending on version, unclip the cover to gain access to the priming pump.  Squeeze and release the priming pump until resistance is felt (could be from the first application) and fuel appears in the transparent pipe with the green connector.  Operate the star ter until the engine star ts.  Depending on version, put the cover back in position and clip it in place.  Close the bonnet.
If the engine does not star t at the first attempt, do not try again. Operate the priming pump again, then the star ter.
 Take the stay out of the suppor t notch.  Clip the stay in its housing.  Lower the bonnet and release it at the end of its travel.  Pull on the bonnet to check that it is fully latched.
