2009.5 Citroen DS3 Owner's Manual

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 a caused by an inrush of air. This vacuum is entirely normal, resulting from the sealing of the fuel system.
To fill the tank in complete safety:  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.

Lighting controls System for selection and control of the various front and rear lamps providing the vehicle's lighting.
The various front and rear lamps of the vehicle
are designed to adapt the driver's visibility progressively according to climatic conditions: - sidelamps, to be seen, - dipped beam headlamps to see without dazzling other drivers, - main beam headlamps to see clearly when the road is clear.
Main lighting
Other lamps are installed to fulfil the requirements of par ticular conditions of
visibility: - a rear foglamp to be seen from afar, - front foglamps for improved vision. - LED lamps to be seen during the daytime.
Additional lighting
Various automatic lighting control modes
are also available according to the following options: - guide-me-home lighting, - automatic illumination of headlamps.
Programming
In some climatic conditions (e.g. low
temperature or humidity), the presence of misting on the internal sur face of the glass of the headlamps and rear lamps is normal; it disappears after the lamps have been on for a few minutes.
