engine Citroen DS3 DAG 2010 1.G Owner's Guide

Gear shift indicator *
Operation
The system inter venes only when driving economically.
Depending on the driving situation and your vehicle's equipment, the system may advise you to skip one or more gears. You can follow this instruction without engaging the intermediate gears. The gear engagement recommendations must not be considered compulsory. In fact, the configuration of the road, the amount of traffic and safety remain determining factors when choosing the best gear. Therefore, the driver remains responsible for deciding whether or not to follow the advice given by the system. This function cannot be deactivated.
- The system may suggest that you engage a higher gear, if appropriate.
The information appears in the instrument panel screen in the form of an arrow accompanied by the suggested gear.
In the case of driving which makes par ticular demands on the per formance of the engine (firm pressure on the accelerator pedal, for example, when over taking...), the system will not recommend a gear change. The system never suggests: - engaging first gear, - engaging reverse gear, - engaging a lower gear.
* According to engine.
Example:
- You are in third gear.
- You press the accelerator pedal moderately.

Displays on the instrument panel
Foot on brake
Press the brake pedal when this indicator lamp is displayed on the instrument panel (e.g.: star ting the engine).
Moving off
If position N is engaged inadver tently while driving, allow the engine to return to idle then engage position D to accelerate.
When the engine is running at idle, with the brakes released, if position R ,
D or M is selected, the vehicle moves even without the accelerator being pressed. When the engine is running, never leave children in the vehicle without super vision. When carrying out maintenance with the engine running, apply the parking brake and select position P . PP
 Apply the parking brake.  Select position P or N .  Star t the engine. If this procedure is not followed, an audible signal is heard, accompanied by a message on the multifunction screen.  With the engine running, press the brake pedal.  Release the parking brake.  Select position R , D or M ,  Gradually release the brake pedal. The vehicle moves off immediately.

151Driving
Automatic operation
 Select position D for automatic changing of the four gears. The gearbox then operates in auto-adaptive mode, without any inter vention on the par t of the driver. It continuously selects the most suitable gear according to the style of driving, the profile of the road and the load in the vehicle. For maximum acceleration without touching the lever, press the accelerator pedal down fully (kick down). The gearbox changes down automatically or maintains the gear selected until the maximum engine speed is reached. On braking, the gearbox changes down automatically to provide efficient engine braking. If you release the accelerator sharply, the gearbox will not change to a higher gear for safety reasons.
Never select position N while the vehicle is moving. Never select positions P or R unless the vehicle is completely stationary.
Sport and snow
programmes
These two special programmes supplement the automatic operation in very specific conditions of use.
Sport programme "S"
 Press button "S" , after star ting the engine. The gearbox automatically favours a dynamic style of driving.
S appears on the instrument panel.
Snow programme "  "
 Press button "  ", after star ting the engine. The gearbox adapts to driving on slippery roads. This programme improves star ting and drive when traction is poor.
 appears on the instrument panel.
Return to automatic
operation
 At any time, press the button selected again to quit the programme engaged and return to auto-adaptive mode.

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.

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.

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.
