Safety -> Under-inflation detection for Your Citroen C3 Picasso SUV Second Generation (2013-2017)

tyres, once the vehicle is moving.  
It compares the information given by the four  
wheel speed sensors with reference values,  
which must be reinitialised every time the  
tyre pressures are adjusted or a wheel  
changed.  
The system triggers an alert as soon as it  
detects a drop in the inflation pressure of one  
or more tyres.  
The inflation pressures defined for  
your vehicle can be found on the tyre  
pressure label.  
For more information on the  
identification markings, refer to the  
corresponding section.  
Tyre pressures should be checked  
when the tyres are "cold" (vehicle  
stopped for 1 hour or after a journey of  
less than 6 miles (10 km) at moderate  
speeds).  
The under-inflation detection system  
does not replace the need for vigilance  
on the part of the driver.  
This system does not avoid the need to  
check the tyre pressures (including the  
spare wheel) every month as well as  
before a long journey.

Otherwise (when hot), add 0.3 bar to  
the pressures shown on the label.  
Driving with under-inflated tyres impairs  
road holding, extends braking distances  
and causes premature tyre wear,  
particularly under arduous condition  
(high loading, high speed, long journey).

if it is not possible to make this check

The loss of pressure detected does not  
always cause visible bulging of the tyre.  
Do not satisfy yourself with just a visual  
check.  
The alert is maintained until the system  
is reinitialised.  
Before reinitialising the system, ensure  
that the pressures of the four tyres are  
correct for the use of the vehicle and in  
line with the recommendations on the  
tyre pressure label.  
The under-inflation detection system  
does not give a warning if a pressure is  
incorrect at the time of reinitialisation.

Operating fault  
Snow chains  
The system does not have to be  
reinitialised after fitting or removing  
snow chains.  
The flashing and then fixed illumination of the  
under-inflation warning lamp accompanied  
by illumination of the Service warning lamp  
indicates a fault with the system.  
In this case, under-inflation monitoring of the  
tyres is no longer assured.  
The under-inflation alert is only  
dependable if the system has been  
reinitialised with all four tyres inflated to  
the correct pressures.  
Have the system checked by a CITROËN  
dealer or a qualified workshop.  
Before doing anything to the system,  
the pressures of the four tyres must be  
checked and the system reinitialised.
