panel indicating that there is a temporary or  
permanent failure.  
Have it checked by a CITROËN dealer or a  
qualified workshop.  
►ꢀ Reduce speed immediately, avoid excessive  
steering movements and avoid sudden braking.  
►ꢀ Stop the vehicle as soon as it is safe to do  
so.  
The system does not advise if a pressure is  
incorrect at the time of reinitialisation.

The reinitialisation of the system is done with  
the ignition on and the vehicle stationary.  
When this warning lamp is displayed on  
the instrument panel, make a long press  
on the "OK" button located on the steering  
wheel to reinitialise the system.  
The loss of pressure detected does not  
always cause visible bulging of the  
tyre.  
Malfunction  
Do not rely on just a visual check.  
The flashing then fixed illumination of the  
under-inflation warning light accompanied by  
the fixed illumination of the service warning  
light indicate a fault in the system.  
In this case, under-inflation monitoring of the  
tyres is no longer assured.  
►ꢀ Check the pressure of the corresponding  
tyre or of the four tyres when cold.  
A message is displayed on the  
instrument panel indicating that the  
reset has been completed.  
►ꢀ If it is not possible to make this check  
immediately, drive carefully at reduced speed.  
►ꢀ In the event of a puncture, replace the  
punctured wheel by the spare wheel.  
►ꢀ Reinitialize the detection system after  
adjusting the pressure.  
If the damaged wheel is replaced with  
one that is not recommended, a  
message is displayed on the instrument  
panel indicating that a spare wheel is  
detected.  
Once the wheel is changed to a  
recommended one, the system must be  
reset.  
Have the system checked by a CITROËN dealer  
or a qualified workshop.  
The alert is kept active until the  
system is reinitialised.  
Parking sensors  
Reinitialisation  
The system must be reinitialised after any  
adjustment to the pressure of one or more  
tyres, and after changing one or more wheels.  
After an intervention of the CITROËN  
dealer for temporary or permanent  
failure, the system must be reset.  
Before reinitialising the system, make  
sure that the pressures of the four  
tyres are correct for the conditions of use of  
the vehicle and conform to the values  
written on the tyre pressure label.  
When there is an error in the signal  
representing deflation or spare tyre, a  
message is displayed on the instrument  
Using sensors located in the bumper, this  
system signals the proximity of obstacles  
(e.g. pedestrian, vehicle, tree, barrier) present in  
their field of detection.  
Check the pressures of the four tyres before  
performing the reinitialisation.

during the whole manoeuvre, in particular  
using the mirrors.  
Rear parking sensors  
The system is switched on by engaging reverse  
gear.  
The system is switched off when disengaging  
reverse gear.  
Audible assistance  
The system signals the presence of obstacles  
within the sensors’ detection zone.  
The proximity information is given by an  
intermittent audible signal, the frequency of  
which increases as the vehicle approaches the  
obstacle.  
When the distance between the vehicle  
and the obstacle becomes less than about  
60 centimetres, the audible signal becomes  
continuous.  
Operating limits  
If the boot is heavily loaded, the vehicle may  
tilt, affecting distance measurements.  
Manoeuvring aids cannot, in any  
circumstances, replace the need for  
vigilance on the part of the driver.  
The driver must always check the  
surroundings of the vehicle before and
