The ESP system offers increased driving safety but is not in place to encourage the driver to take addi-tional risks or to drive at excessive speeds.
The functioning of this system is subject to compliance with the manufacturer’s recommendations on wheels (tyres and rims), brake parts and electronic components, as well as with the assembly and repair procedures approved by CITROËN.repair procedures repair procedures

ELECTRONIC STABILITY PROGRAMME (ESP) AND TRACTION CONTROL (ASR)
These systems are closely associated with ABS and additional to it. In the event of a loss of control of the vehicle by the driver, the ESP system acts automatically on one or more wheels and also on the engine to bring the vehicle back on trajectory. The ASR system optimises traction and prevents wheel spin by acting on the brakes of the driving wheels as well as on the engine. It also improves steering stability during acceleration.
OPERATION
When either the ESP or the ASR system is brought into operation the warning lamp “ESP/ASR” fl ashes.
DEACTIVATION
In exceptional conditions (vehicle stuck in snow, soft ground, e tc.) it may prove useful to deactivate the ESP/ASR systems to allow the wheels to spin and thus regain traction.
Press on button A, the “ESP/ASR” warning lamp, as well as the lamp on the button A, light up. The ESP/ASR systems are no longer active.
The ESP/ASR systems will activate again:Automatically after the ignition has been switched off.
Automatically when you drive at above approx. 50 km/h (approx. 30 mph).Manually with another press on button A.
OPERATIONAL ANOMALY
Should there be a system malfunction, the “ESP/ASR” warning lamp will light up.
Contact a CITROËN dealer to have the system checked.

In addition to the catalytic converter, this fi lter contributes actively to the preserving of air quality, by collecting the polluting particles that have not been burnt off. Black exhaust fumes are thus eliminated.
Simultaneous lighting of the SERVICE and depollution system warning lamps indicates an increased risk of clogging.
Contact a CITROËN dealer as soon as possible.
DIESEL ADDITIVE LEVEL
If the additive level is low, it is necessary to top up the additive level.
Contact a CITROËN dealer as soon as possible.
CLOGGING OF THE PARTICLE FILTER
Clogging is caused by the particle fi lter starting to be satu rated (owing to exceptionally long periods spent driving in urban conditions : low speeds, traffi c jams, e tc.).
In order to regenerate the fi lter you are advised to drive as so on as possible, when traffi c conditions allow, at a speed of 60 km/h (37 mph) or more for at least 5 mi nutes. If the problem persists, contact a CITROËN In order to regenerate the fi lter you are advised to drive as soon as possible, when traffi c conditions In order to regenerate the fi lter you are advised to drive as soon as possible, when traffi c conditions

As the vehicle approaches the obstacle, the sound signal becomes more and more urgent and the shaded areas are displayed closer and closer to the vehicle.
Proximity sensors are located in the front and rear bumpers of your vehi-cle.
When manœuvring in either forward or reverse gear, at a low speed less than approx. 10 km / h (6 mph), they inform you of the presence of any obstacle that is within their zone of detection by: A sound signal emitted by the front or rear loudspeakers.ADisplay of the outline of your vehicle with shading corresponding t o the area where an obstacle is detected.
As the vehicle approaches the obstacle, the sound signal tells you the posi-tion of the obstacle according to whether the sound is coming from the front LH or RH or the rear LH or RH loudspeakers.Note: The sound volume of your audio equipment reduces automatically when a signal is being emitted.

ACTIVATION/DEACTIVATION
You can activate/deactivate the parking assistance by pressing button 1. When the parking assist-ance is inactive, the warning lamp on button 1 is lit up.
Activation/deactivation of the park-ing assistance is memorised when you stop the vehicle.
Remark: If you wish to tow a trailer, it is necessary to deactivate the parking assistance by pressing button 1. The warning lamp on the button lights up.
OPERATION
When you engage reverse gear, a sound signal confi rms to you that the system is active. The out-line of your vehicle appears on the screen. Any obstacles located to the rear or to the front of the vehi-cle can be detected.
When moving forward at a speed less than approx. 10 km / h (6 mph), whether in neutral or in gear, the vehi-cle outline appears on the screen as soon as an obstacle is detected in front of the vehicle. Any obstacles located to the rear or to the front of the vehicle can be detected.
Remarks:The proximity sensors cannot detect objects that are immedi-ately under or over the bump-ers.
A thin object such as a spike, Aa bollard or similar, can only be detected at the start of the manœuvre but not when the vehicle arrives close up to it.In poor weather or in winter, you need to ensure that the sensors are not covered with mud or with ice or snow.
