2010.5 Citroen DS4 fuel

Fuel tank Capacity of the tank: approximately 60 litres.
Low fuel level
Refuelling
Additions of fuel must be of at least 5 litres to be registered by the fuel gauge. Opening the filler cap may result in an inrush of air. This vacuum is entirely normal and results
from the sealing of the fuel system.
 Press control A until the automatic opening of the fuel flap is heard. This control remains active for a few minutes after switching off the ignition. If necessary, switch the ignition on again to reactivate it.  Take care to select the pump that delivers the correct fuel for your vehicle.
 Introduce the nozzle so as to push in the metal non-return flap B.  Make sure that the nozzle is pushed in as far as possible before star ting to refuel (risk of blowback).  Maintain this position while refuelling.  Push the fuel flap to close it. If you are filling your tank to the top, do not persist after the third cut- off; this could cause your vehicle to malfunction.
When the low fuel level in the tank is reached, this warning lamp on
the instrument panel comes on, accompanied by an audible warning and a message in the screen. When it first comes on, around 6 litres of fuel remain in the tank. You must refuel as soon as possible to avoid running out.
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. Contact a CITROËN dealer or a qualified workshop. 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).
The petrol or Diesel engine of your vehicle is fitted with a catalytic conver ter, a device which helps to reduce the level of harmful emissions in the exhaust gases. For petrol engines, the use of unleaded fuel is compulsor y. The filler neck is narrower, admitting unleaded petrol nozzles only.
Fuel supply cut-off
Your vehicle is equipped with a safety device which cuts off the fuel supply in the event of a collision.
If you have put in the wrong fuel for your vehicle, you must have have the tank drained and refilled with the correct fuel before you star t the engine.

Misfuel prevention Mechanical device which prevents filling the tank of a Diesel vehicle with petrol. It avoids the risk of engine damage that can result from filling with the wrong fuel. Located in the filler neck, the misfuel prevention device appears when the filler cap is removed.
When a petrol filler nozzle is introduced into the fuel filler neck of your Diesel vehicle, it comes into contact with the flap. The system remains
closed and prevents filling. Do not persist but introduce a Diesel type filler nozzle.
Operation
It is still possible to use a fuel can to fill the reser voir. In order to ensure a good flow of fuel, do not place the nozzle of the fuel can in direct contact with the flap of the misfuel prevention device.
This equipment will become available during the year.

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 y ou 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 the noise level when stationary.
Operation
Going into engine STOP mode
With the automatic gearbox system, for your comfor t during parking maoeuvres, 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), when you put the gear lever into neutral and release the clutch pedal, - with the 6-speed electronic gearbox system , at a speed below 5 mph (8 km/h),
when you press the brake pedal or put the gear lever into position N .
If your vehicle is fitted with the system, a time counter calculates the sum of the periods in STOP mode during a journey. It resets 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 start using the key, - the electric parking brake is applied or being applied, - 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
In this case, the "ECO" warning lamp flashes for a few seconds, then goes off. This operation is per fectly normal.

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; refer to the engine compar tment view on the "Diesel engine" page.
1.6 litre Turbo HDI engine
 Fill the fuel tank with at least five litres of diesel.  Open the bonnet.  Squeeze and release the priming pump repeatedly until it hardens (it may be hard at the first press).  Operate the star ter until the engine star ts.  Close the bonnet.
If the engine does not star t first time, don't keep trying. Operate the priming pump again, then the star ter motor.
 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 secured correctly.
2 litre Turbo HDI engine
 Fill the fuel tank with at least five litres of
Diesel.  Open the bonnet.  Unclip the style cover for access to the priming pump.  Slacken the bleed screw.  Squeeze and release the priming pump repeatedly until fuel appears in the transparent pipe with the green connector.  Retighten the bleed screw.  Operate the star ter until the engine star ts.  Put the style cover back in position and clip it in place.  Close the bonnet.
