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 The ESP/ASR systems are no longer active.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

Sensors
The automatic regulation of the air conditioning inside the cabin uses a number of sensors that relieve you of the need to make adjust-ments outside the displayed tem-perature.
Be careful not to obstruct the sun-light sensor located on the dash-board.
Air inlet
Check that the exterior grille for the air inlet, at the bottom of the windscreen, is clean and free of dead leaves, snow, etc.
Air vents
The air vents to the face have grilles and thumbwheels so that you can adjust the air fl ow and direction (up-down, right-left).
Air circulation
Air vents on the fl oor underneath the front seats provide enhanced heating for the rear seat positions : take care not to obstruct them.
Dust fi lter / odour fi lter (active carbon)
There is a fi lter for excluding odours and dust.
This fi lter has to be changed in accordance with the vehicle main-tenance schedule (see the Main-tenance Guide).
Air conditioning
To ensure that your system oper-ates correctly, it is recommended to have it checked regularly.
Water arising from condensation in the air conditioning drains away through a hole provided for this purpose. A pool of water may thus form under the vehicle when sta-tionary.
To keep the air conditioning com-pressor well sealed, it is essential to operate the air conditioning at least once in every month.
To be effective, the air condition-ing should only be used with the windows closed.
If after a lengthy stop in bright sunlight the interior temperature is excessive, ventilate the passen-ger compartment by opening the windows for a few moments, then close them again.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel consumption.
