Safety -> Under-inflation detection for Your Citroen C3 SUV Second Generation (2009-2016)

Safety  
Under-inflation detection  
System which automatically checks the pressures of the tyres while driving.  
The system monitors the pressures in the four  
The under-inflation detection system  
The inflation pressures defined for  
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.  
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.  
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).  
your vehicle can be found on the tyre  
pressure label.  
See the "Identification markings"  
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).  
Otherwise (when hot), add 0.3 bar to  
the pressures shown on the label.

if it is not possible to make this check  
immediately, drive carefully at reduced  
speed.  
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.
