Driving -> Under-inflation detection for Your Citroen C3 SUV Third Generation (2016-2024)

Driving  
After the engine has restarted, STOP  
mode is not available until the vehicle  
has reached a speed of 5 mph (8 km/h).  
In these cases, this indicator lamp flashes  
for a few seconds, then goes off.  
The system triggers an alert as soon as it  
detects a drop in the inflation pressure of one or  
more tyres.  
Malfunctions  
Under-inflation detection does not  
replace the need for vigilance on the part  
of the driver.  
This system does not avoid the need to  
regularly check the tyre pressures (including  
the spare wheel) as well as before a long  
journey.  
Driving with under-inflated tyres, particularly  
in adverse conditions (heavy load, high  
speed, long journey):  
In the event of a malfunction, this warning  
lamp flashes for a few moments, then  
remains on, accompanied by an onscreen  
message.  
During parking manoeuvres, STOP mode  
is not available for a few seconds after  
coming out of reverse gear or turning the  
steering wheel.  
Have the vehicle checked by a CITROËN dealer  
or a qualified workshop.  
Engine restarting (START mode)  
The vehicle stalls in STOP mode  
The engine automatically restarts as soon as the  
driver indicates the intention of moving off again.  
With a manual gearbox: with the clutch  
pedal fully depressed.  
With an automatic gearbox:  
• With the selector in position D or M: with the  
brake pedal released.  
• With the selector in position N and the brake  
pedal released: with the selector at D or M.  
• With the selector in position P and the brake  
pedal depressed: with the selector at R, N,  
D or M.  
All of the instrument panel warning lamps come  
on if there is a fault.  
► Switch off the ignition then start the engine  
again with the key or the "START/STOP" button.  
– worsens road-holding.  
– lengthens braking distances.  
– causes premature wear of the tyres.  
– increases fuel consumption.  
The Stop & Start system requires a 12 V  
battery of specific technology and  
specification.  
All work concerning the battery must be  
carried out only by a CITROËN dealer or a  
qualified workshop.  
The inflation pressures defined for the  
vehicle can be found on the tyre pressure  
label.  
For more information on the Identification  
markings, refer to the corresponding section.  
• Reverse gear engaged.  
Under-inflation detection  
Special cases  
Checking tyre pressures  
This check should be done when the  
tyres are "cold" (vehicle stopped for 1 hour or  
after a journey of less than 6 miles (10 km) at  
moderate speeds).  
This system automatically checks the pressures  
of the tyres while driving.  
The engine will restart automatically if all  
conditions for operation are met again and in the  
following cases.  
– Speed of the vehicle exceeds 2 mph (3 km/h).  
– Some specific conditions (braking assistance,  
air conditioning setting, etc.).  
It compares the information given by the wheel  
speed sensors with reference values, which  
must be reinitialised every time the tyre  
pressures are adjusted or a wheel changed.  
Otherwise, add 0.3 bar to the pressures  
shown on the label.

Driving  
Reinitialisation is confirmed by a high-pitched  
audible signal.  
A deep tone audible signal indicates that the  
reinitialisation has not been done.  
Snow chains  
Reinitialisation  
The system must be reinitialised after any  
adjustment to the pressure of one or more tyres,  
and after changing one or more wheels.  
6
The system does not have to be  
reinitialised after fitting or removing snow  
chains.  
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.  
Check the pressures of the four tyres before  
performing the reinitialisation.  
The system does not advise if a pressure is  
incorrect at the time of reinitialisation.  
Malfunction  
Under-inflation alert  
These warning lamps come on in  
the event of a malfunction.  
This is signalled by the fixed illumination  
of this warning lamp, accompanied by an  
audible signal and, depending on equipment, the  
display of a message.  
A message appears, accompanied by an audible  
signal.  
In this case, the tyre under-inflation monitoring  
function is no longer performed.  
Have the system 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 reinitialisation of the system is done with the  
ignition on and the vehicle stationary:  
– Via the vehicle configuration menu for vehicles  
fitted with a touch screen.  
– Via the instrument panel display screen or via  
the button on the dashboard for vehicles without  
a screen.  
– Via the instrument panel display screen for  
vehicles without a screen.  
With the vehicle stationary, the system is  
reinitialised via the Driving/Vehicle touch  
screen menu.  
The loss of pressure detected does not  
always cause visible bulging of the tyre.  
Do not rely on just a visual check.

(Depending on country of sale.)  
► Using 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 make this check  
immediately, drive carefully at reduced speed.  
► In the event of a puncture, use the  
temporary puncture repair kit or the spare wheel  
(depending on equipment).  
Instrument panel display screen  
The alert is kept active until the system is  
reinitialised.  
This camera, installed at the top of the  
windscreen and connected wirelessly, allows  
you to:  
Take photos and videos on demand and share  
them.  
► Press this button briefly to go to the
