2010 Citroen DS3 DAG warning

Curtain airbags
System which protects the driver and passengers (with the exception of the rear centre passenger) in the event of a serious side impact in order to limit the risk of injury to the side of the head. Each cur tain airbag is built into the pillars and the upper passenger compar tment area.
Activation
The cur tain airbag is triggered at the same time as the corresponding lateral airbag in the event of a serious side impact applied to all or par t of the side impact zone B , perpendicular to the longitudinal centreline of the vehicle on a horizontal plane and directed from the outside towards the inside of the vehicle. The cur tain airbag inflates between the front or rear occupant of the vehicle and the windows.
Operating fault
In the event of a minor impact or bump on the side of the vehicle or if the vehicle rolls over, the airbag may not be triggered. In the event of a rear or front collision, the airbag is not triggered.
If this warning lamp comes on on the instrument panel, accompanied by an audible signal and a message on the multifunction screen, contact a CITROËN dealer to have the system checked. The
airbags may no longer be triggered in the event of a serious impact.

Parking brake
Applying
 Pull the parking brake lever fully up to immobilise your vehicle.
Releasing
 Pull the parking brake lever gently, press the release button then lower the lever fully.
When parking on a slope, direct your wheels against the pavement, apply the parking brake and engage a gear.
When the vehicle is being driven, if this warning lamp and the STOPwarning lamp come on, accompanied
by an audible signal and a message on the multifunction screen, this indicates that the parking brake is still on or has not been properly released.

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.

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.

Programming Operating faults
If there is an operating fault, when reverse gear is engaged this warning lamp comes on on the instrument panel, accompanied by an audible signal (shor t beep) and a message on the multifunction screen.
You can activate or deactivate the system by means of the multifunction screen configuration menu. The system state is memorised when switching off the ignition. For more information on access to the parking sensors menu, refer to "Configuration/ Vehicle parameters" in the "Multifunction screens" section corresponding to your screen.
The system will be deactivated automatically when towing a trailer or when a bicycle carrier is fitted (vehicle fitted with a towbar or bicycle carrier recommended by CITROËN).
In bad or wintry weather, ensure that the sensors are not covered with mud, frost or snow.
