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
After any collision, contact a CITROËN dealer.
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
If either of the ESP or ASR systems is active, the warning lamp 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 control A, the warning lamp and the light on control A light up. The ESP/ASR systems are no longer active.
The ERSP/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
If there is a system fault, the warning lamp lights up, accompa nied by a message on the instrument panel screen, the lighting of the SERVICEwarning lamp and a beep.

“Hydractive III +” suspension auto-matically adjusts to road surface conditions and driving style.
It allows you to alternate between soft and fi rm suspension settings, maximising comfort at the same time as permanently guaranteeing the highest level of safety. It also automatically corrects road hold-ing, according to the vehicle load and driving conditions.
Also, the “Hydractive III +” suspen-sion gives you the possibility of choosing between two modes of suspension.
A change of suspension mode can be made either when the vehicle is moving or when stationary, by pressing on button A.
Signalling
Sport mode, more suited for a sporty style of driving
A message is displayed on the instrument panel and the warning lamp on button A comes on.
Note: Sport mode is retained when you switch off the engine.
Note: If the speed authorised for a particular position is exceeded, the vehi-cle reverts automatically to the normal road position.
Note: Automatic variation of ground clearanceIf your speed exceeds 110 km/h (approx. 70 mph), on a good road surface, ground clearance is lowered. The vehicle returns to its normal position if the road sur-face deteriorates or if your speed is lower than 90 km/h (approx. 55 mph).
At low or medium speed, if the road surface is deteriorated, ground clearance is increased. The vehi-cle returns to its normal position once one of these two conditions is no longer observed.
