Peugeot 2008 II (2019-2023) tyre under-inflation detection: how it works, what to do when the alert comes on, reinitialising and malfunctions.
Hello and welcome. In this article we look at the tyre under-inflation detection system on the Peugeot 2008 II (2019-2023). We will cover how it works, what to do when the alert comes on, how to reinitialise it, what a malfunction means and where to find the tyre pressure label.

| Section | In short |
|---|---|
| Tyre under-inflation detection | How the system detects pressure loss and checking pressures |
| Under-inflation alert | What to do when the under-inflation lamp comes on |
| Reinitialisation | Reset after adjusting pressures or changing a wheel |
| Malfunction | Monitoring stops, have the system checked |
| Identification markings | Where to find the VIN and tyre pressure label |
The tyre under-inflation detection system alerts you if one or more tyres lose pressure. It only raises the alert when the car is moving, not when it is stationary.
The system never replaces your own vigilance as a driver. You still need to check the tyre pressures regularly, including the spare wheel, especially before a long journey. Driving on under-inflated tyres, particularly with a heavy load, at high speed or on a long journey, has these effects:
You can find the inflation pressures for your car on the tyre pressure label. See the Identification markings section below for where to find it.
Checking tyre pressures: check them monthly when the tyres are "cold", meaning the car has been stopped for 1 hour or has done a journey of less than 6 miles (10 km) at moderate speeds. If the tyres are not cold, add 0.3 bar to the pressures shown on the label.
You do not need to reinitialise the system after fitting or removing snow chains.
The alert is shown by the warning lamp lighting up steadily, together with an audible signal and, depending on equipment, a message.
A loss of pressure does not always cause visible deformation of the tyre, so do not rely on a visual check alone. Keep these points in mind:
The alert stays active until you reinitialise the system.
You must reinitialise the system after adjusting the pressure of one or more tyres, and after changing one or more wheels.
The system does not tell you if a pressure is incorrect when you reinitialise it, so the check beforehand is essential.
If the system develops a fault, the warning lamps light up on the instrument panel and a message appears with an audible signal. Tyre under-inflation monitoring is then no longer carried out, so have the system checked by a PEUGEOT dealer or a qualified workshop.
Non-standard or 'space-saver' spare wheel: using this type of spare wheel may suspend tyre pressure monitoring. The malfunction warning lamp comes on and goes off once the wheel has been replaced by one the same size as the others, the pressure has been readjusted and the system has been reinitialised.
Your car carries several visible markings for identification and vehicle search.
Scroll the table sideways.
| Marking | Location | Details |
|---|---|---|
| A. Vehicle Identification Number (VIN) | Under the bonnet | Stamped on the chassis |
| B. Vehicle Identification Number (VIN) | On the dashboard | Printed on an adhesive label visible through the windscreen |
| C. Manufacturer's label | Right-hand door | Identification and weight information |
| D. Tyres/paint code label | Driver's door | Tyre information and paint colour code |
The manufacturer's label shows:
The tyres/paint code label shows the paint colour code and this tyre information:
Your car may have been fitted from new with tyres that have higher load and speed indices than those on the label, and this does not affect the tyre pressures (on cold tyres). If you want to change the type of tyres, contact a PEUGEOT dealer for the tyre fits approved for your car.
The tyres/paint code label is on the driver's door. It shows the tyre pressures unladen and laden, as well as the spare tyre inflation pressure.
First check that all four tyres are at the pressures on the tyre pressure label. Then, with the car stationary, reinitialise the system through the Driving/Vehicle menu on the touch screen.
The alert is not triggered immediately after a sudden loss of pressure or a blow-out, because analysing the wheel speed sensor values can take several minutes. It may also be delayed below 25 mph (40 km/h) or in a sporty driving mode.
No. The system does not need to be reinitialised after fitting or removing snow chains.
The under-inflation detection system is a useful backup, but it does not replace your own monthly pressure checks. Keep the pressures matched to the label on the driver's door, reinitialise the system whenever you adjust them or change a wheel, and your 2008 will be able to warn you properly if a tyre loses pressure.
