PRACTICAL ADVICE -> Tyre Pressure Sensors for Your Citroen C4 SUV First Generation (2004-2010)

T Y R E P R E S S U R E S E N S O R S  
This function alerts you in the  
event of a tyre being deflated  
or punctured. For this purpose,  
sensors continuously monitor the  
condition of the vehicle’s wheels.  
This system does not absolve the  
driver of the need to check the tyre  
pressures regularly.  
Change the damaged wheel (whether punctured or substantially deflated),  
have the tyre repaired as soon as possible, then check the tyre pressure  
as soon as you can after that.  
The wheel affected will no longer be detectable by the alert system if it is  
in the boot or undergoing repair (information given by the vehicle outline).  
The spare wheel will not be monitored by the alert system.  
Wheel without sensor  
The SERVICE warning lamp lights up and a vehicle outline is  
displayed. The wheel(s) concerned will be shown as absent on  
the vehicle outline. If you have not changed a wheel, this infor-  
mation indicates a malfunctionong of the system.  
Under-inflation warning  
The SERVICE warning  
lamp lights up and a  
vehicle outline is dis-  
played.  
Consult the CITROËN network to have the defective sensor(s)  
replaced.  
The deflation detection system is a driving assistance function which does  
not absolve the driver from the responsibility to be vigilant, or from the  
need to check the tyre pressures regularly (see “Vehicle identification”).  
This system does not absolve the driver of the need to check the tyre  
pressures on a regular basis (see «Identification»), to ensure that the  
vehicle behaves as it should and to avoid premature wear on the tyres,  
especially when the vehicle is being subjected to heavy loads or driven at  
high speeds.  
The wheel(s) concerned  
will be shown flashing  
on the vehicle outline. Check the  
tyre pressures as soon as pos-  
sible.  
Do not forget to check the tyre pressure on the spare wheel.

Puncture

lights up and a vehicle  
outline is displayed.

the vehicle outline. Stop  
the vehicle immediately, avoiding  
any violent actions on the steering  
wheel or brakes.  
Any repair or any change of tyre, on a wheel fitted with a sensor,  
should be carried out by a CITROËN Dealer.  
The system may be affected from time to time by interference  
from radio transmissions on similar frequencies.
