2010 Citroen DS3 DAG warning light

153Driving
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.

Diesel additive level
(Diesel engine with particle
emission filter)
A low additive level is indicated by lighting of the ser vice warning lamp, accompanied by an audible warning and a message on the multifunction screen.
Topping up
This additive must be topped up by a CITROËN
dealer without delay.
Used products
Avoid prolonged contact of used oil or fluids with the skin. Most of these fluids are harmful to health or indeed very corrosive.
Do not discard used oil or fluids into sewers or onto the ground. Take used oil to a CITROËN dealer (France) or an authorised waste disposal site.

209Practical information
The rear parking sensors will be deactivated automatically if a genuine
CITROËN towbar is used.
Driving advice
Distribution of loads
 Distribute the load in the trailer so that the heaviest items are as close as possible to the axle and the nose weight approaches the maximum permitted without exceeding it. Air density decreases with altitude, thus reducing engine per formance. Above 1 000 metres, the maximum towing load must be reduced by 10 % and so on for every 1 000 metres of altitude. Refer to the "Technical Data" section for details of the weights and towing loads which apply to your vehicle.
Side wind
 Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the temperature of the coolant. As the fan is electrically controlled, its cooling capacity is not dependent on the engine speed.  To lower the engine speed, reduce your speed. The maximum towing load on a long slope depends on the gradient and the ambient temperature. In all cases, pay attention to the coolant temperature.
Braking
Towing a trailer increases the braking distance.
Tyres
 Check the tyre pressures of the towing vehicle and of the trailer, obser ving the recommended pressures.
Lighting
 Check the electrical lighting and signalling on the trailer.
 If the warning lamp and the STOP warning lamp come on, stop the vehicle and switch off
the engine as soon as possible.

* The weight of the braked trailer can be increas ed, within the GTW limit, if the GV W of the towing vehicle is reduced by an equal amount. Warning: towing using a lightly loaded towing vehicle may have an adverse effect on its road holding.
The GTW and towed load values indicated are valid u p to a maximum altitude of 1 000 metres; the towed load mentioned must be reduced by 10 % for each additional 1 000 metres of altitude. The speed of a towing vehicle must not exceed 60 m ph (100 km/h) (comply with the legislation in force in your country). High ambient temperatures may result in a reduction in the per formance of the vehicle to protect the engine; if the ambient temperature is above 37 °C, limit the towed load.
