Driving -> Under-inflation detection for Your Citroen C1 4 Door Second Generation (2014-2022)

Driving  
Under-inflation detection  
System which automatically checks the pressures of the tyres while driving.  
The under-inflation detection system  
does not replace the need for vigilance  
on the part of the driver.  
Driving with under-inflated tyres  
increases fuel consumption.  
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).  
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.  
4
The system monitors the pressures in the four  
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.  
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.

Under-inflation alert  
Reinitialisation  
This is given by fixed illumination of  
this warning lamp, accompanied by  
an audible signal.  
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 alert can only be  
relied on if the reinitialisation of the  
system has done with the pressures in  
the four tyres correctly adjusted.  
F
F
Reduce speed immediately, avoid  
excessive steering movements and sudden  
braking.  
Stop the vehicle as soon as it is safe to  
do so.  
The loss of pressure detected does not  
always cause visible bulging of the tyre.  
Do not satisfy yourself with just a visual  
check.  
The under-inflation detection system  
does not give a warning if a pressure is  
incorrect at the time of reinitialisation.  
It is necessary to reinitialise the system every  
time one or more tyre pressures are adjusted,  
and after changing one or more wheels.  
A label attached to the middle pillar, driver's  
side, gives a reminder of this.  
F
If you have a compressor (such as the one  
in the temporary puncture repair kit) check  
the pressures of the four tyres when cold.  
If it is not possible to carry out this check  
straight away, drive carefully at reduced  
speed.  
or  
F
In the event of a puncture, use the  
temporary puncture repair kit or the spare  
wheel (depending on equipment).  
The alert is maintained until the system  
is reinitialised.

Operating fault  
The flashing and then fixed illumination  
of the under-inflation warning lamp  
indicates a fault with the system.  
Snow chains  
The system does not have to be  
reinitialised after fitting or removing  
snow chains.  
In this case, under-inflation monitoring of the  
tyres is no longer assured.  
4
Have the system checked by a CITROËN  
dealer or a qualified workshop.  
The under-inflation alert can only be  
considered reliable if reinitialisation of  
the system is done with the the four tyre  
pressures correctly set.  
Before doing anything to the system,  
the pressures of the four tyres must be  
checked and the system reinitialised.  
Reinitialisation of the system is done with the  
ignition on (ignition switch in the "ON" position  
or "ON" mode) and the vehicle stationary.  
F
F
Open the glove box.  
Press the reinitialisation button.  
F
This warning lamp flashes  
3 times in the instrument panel  
when the reinitialisation is done.  
F
Wait a few minutes before switching off the  
ignition (ignition switch in the "ACC"  
or "LOCK" position, or "OFF" mode).  
The new pressure settings registered  
are considered to be reference values by  
the system.
