2009.5 Citroen DS3 engine

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.

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).

A. Cour tesy lampB. Map reading lamps
Courtesy lamp
In this position, the cour tesy lamp comes on gradually:
Courtesy lamp
- when the vehicle is unlocked, - when the key is removed from the ignition, - when a door is opened, - when the remote control locking button is activated, in order to locate your vehicle.
It switches off gradually: - when the vehicle is locked, - when the ignition is switched on, - 30 seconds after the last door is closed.
Permanently off.
Permanent lighting.
With the "permanent lighting" mode, the duration of lighting varies, depending on the circumstances: - with the ignition off, approximately ten minutes, - in energy economy mode, approximately thir ty seconds, - with the engine running, unlimited.
Map reading lamps
 With the ignition on, press the corresponding switch.

111Visibility
Interior mood lighting
The dimmed passenger compar tment lighting improves v isibility in the vehicle when the light is poor.
Switching on
At night, the illumination of footwells and the central dashboard storage compar tment comes on automatically when the sidelamps are switched on.
Switching off
The interior mood lighting switches off automatically when the sidelamps are switched off. It can be switched off manually using the instrument panel lighting rheostat button.  With the lighting on, press several times on the left hand button of the instrument panel to progressively reduce the dashboard lighting level.  Press again to reduce the lighting level to the minimum and switch off the interior mood lighting.
This comes on automatically when the boot is opened and switches off automatically when the boot is closed.
Boot lamp
Different lighting times are provided: - when the ignition is off,
approximately ten minutes, - in energy economy mode, approximately thir ty seconds, - when the engine is running, no limit.

135Safety
Emergency braking assistance
System which, in an emergency, enables you to obtain the optimum braking pressure more quickly, thus reducing the stopping distance.
Activation
It is triggered by the speed at which the brake pedal is pressed. The effect of this is a reduction in the resistance of the pedal and an increase in braking efficiency.
When braking in an emergency, press firmly without releasing the pressure.
Trajectory control systems
Anti-skid regulation (ASR)
and electronic stability
programme (ESP)
The anti-skid regulation (also known as Traction Control) optimises traction to prevent skidding of the wheels, by acting on the brakes of the driving wheels and on the engine. The electronic stability programme acts on the brake of one or more wheels and on the engine to keep the vehicle on the trajectory required by the driver, within the limits of the laws of physics.
Activation
These systems are activated automatically each time the vehicle is star ted. They come into operation in the event of a grip or trajectory problem.
This is indicated by flashing of this warning lamp on the instrument panel.

Deactivation
In exceptional conditions (star ting a vehicle which is bogged down, stuck in snow, on soft ground...), it may be advisable to deactivate the ASR and ESP systems, so that the wheels can
move freely and regain grip.  Press the "ESP OFF" button, located on the left below the steering wheel.
If this warning lamp comes on in the instrument panel and the indicator lamp on the button comes on, this indicates that the ASR and ESP systems are deactivated.
Reactivation
These systems are reactivated automatically each time the ignition is switched back on or from 30 mph (50 km/h) (except 1.6 litreTHP 150 petrol engine).
 Press the "ESP OFF" button again to reactivate them manually.
Operating fault
The ESP/ASR systems offer exceptional safety in normal driving, but this should not encourage the driver to take extra risks or drive at high speed. The correct functioning of these systems depends on obser vation of the manufacturer's recommendations regarding the wheels (tyres and rims), the braking components, the electronic components and the CITROËN assembly and operation procedures. After an impact, have these systems checked by a CITROËN dealer.
If this warning lamp comes on, accompanied by an audible signal and a message on the multifunction screen, this
indicates a malfunction of these systems. Have the systems checked by a CITROËN dealer.

149Driving
6-speed manual gearbox
 Raise the ring under the knob and push the gear lever to the left then for wards.
Engaging reverse gear
As a safety precaution and to facilitate star ting of the engine: - always select neutral, - press the clutch pedal.
Only engage reverse gear when the vehicle is stationary with the engine at idle.
