Advice
Vehicles equipped with a turbocharger
Never stop the engine without having allowed it to run for a few seconds at idle, this being the time required for t he turbocharger to return to a normal speed.
"Flicking the accelerator" at the moment of switching off the i gnition could cause serious damage.
Note : If the engine fails to start at the fi rst attempt, switch off the ignition. Wait ten seconds, then action the starte r again as indicated above.
Automatic gearbox

SAFETY RECOMMENDATIONS
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 CITROËN’s as-parts and electronic components, components,
sembly and repair procedures.
After any collision, have this system checked by a CITROËN dealer.After any collision, have this system , have t
Electronic stability programme (ESP) and traction control (ASR)
These systems are closely connected to the 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 brakes 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 ASR system is in operation, the ESP/ASR 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 system to allow the wheels to spin and thus regain traction.
- Press on control A, the ESP/ASR warning lamp and the control 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 The ESP/ASR systems are no longer active.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 above a speed of 50 km/h (30 mph).
- Manually with a new press on control A.
Operational anomaly
If the systems malfunction, the ESP/ASR warning lamp comes on, ac-companied by a sound signal and a message on the multifunction display. Contact a CITROËN dealer to have the system checked.companied by a sound signal and a message on the multifunction by a sound
