2009.5 Citroen DS3 DAG ESP

131Safety
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.

139Safety
Lateral airbags
System which protects the driver and front passenger in the event of a serious side impact in order to limit the risk of injury to the chest. Each lateral airbag is built into the seat backrest frame, door side.
Activation Impact detection zones
A. Front impact zone. B. Side impact zone.
The lateral airbags are triggered unilaterally 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 lateral airbag inflates between the front
occupant of the vehicle and the corresponding door trim panel.

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.

Gear change 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 form of an arrow on the instrument panel display. Depending on your vehicle's equipment, this arrow may be accompanied by the recommended 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.

When you move the lever in the gate to select a position, the corresponding indicator is displayed on the instrument panel. P. Park R. Reverse N. Neutral D. Drive (Automatic driving) S. Spor t programme  . Snow programme 1, 2, 3, 4. Gear engaged during manual operation -. Invalid value during manual operation

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
System which prevents the vehicle from exceeding the speed programmed by the driver. When the programmed speed limit is reached, pressing the accelerator pedal in the normal manner no longer has any effect. The speed limiter is switched on manually: it requires a programmed speed of at least 20 mph (30 km/h). The speed limiter is switched off by manual d offoperation of the control. The programmed speed can be exceeded temporarily by pressing the accelerator firmly. To return to the programmed speed, simply slow down to a speed below the programmed speed. The programmed speed remains in the memory when the ignition is switched off.
Speed limiter
The speed limiter cannot, in any circumstances, replace the need to respect speed limits, nor can it replace the need for vigilance and responsibility on the par t of the driver.

153Driving
Cruise control
System which automatically maintains the speed of the vehicle at the value programmed by the driver, without any action on the accelerator pedal. The cruise control is switched on manually: it requires a minimum vehicle speed of 25 mph (40 km/h), as well as the engagement of: - four th gear on a manual gearbox, - second gear on an automatic gearbox, in sequential mode, - position D on an automatic gearbox. The cruise control is switched off manually d offor by pressing the brake or clutch pedal or on triggering of the ESP system for safety reasons. It is possible to exceed the programmed speed temporarily by pressing the accelerator pedal. To return to the programmed speed, simply release the accelerator pedal. Switching off the ignition cancels any programmed speed value.
