How the Peugeot 208 under-inflation detection system works, what to do when the alert comes on, how to reinitialise it and where to find the tyre label.
Your Peugeot 208 can warn you when one or more tyres lose pressure. This guide explains how the under-inflation detection system works, what to do when the alert comes on, how to reinitialise the system and where to find the tyre pressure label and the other identification markings on your car.

| Section | In short |
|---|---|
| Under-inflation detection | How the system monitors pressure in all four tyres |
| Under-inflation alert | Slow down, stop safely and check the tyres |
| Reinitialisation | Reset after any pressure adjustment or wheel change |
| Malfunction | Flashing lamp plus Service lamp means system fault |
| Identification markings | Where to find the VIN and tyre pressure label |
The under-inflation detection system automatically monitors the pressure in all four tyres once the car is moving. It compares information from the wheel speed sensors with reference values, and triggers an alert as soon as it detects a drop in pressure in one or more tyres.
The reference values must be reinitialised after every tyre pressure adjustment or wheel change.
The system does not replace your own vigilance as the driver. You still need to check the tyre pressures yourself:
Driving on under-inflated tyres impairs handling, extends braking distances and causes early tyre wear, especially with heavy loads, at high speeds or on long journeys. It also increases fuel consumption.
The alert is shown by the warning lamp staying on, an audible signal and, depending on equipment, a message on the screen.
A loss of pressure does not always make the tyre bulge visibly, so do not rely on a visual check alone. Then do one of the following:
The alert stays active until the system is reinitialised, and you can only rely on it if the system was reinitialised with all four tyre pressures correctly adjusted.
You must reinitialise the system after adjusting the pressure of one or more tyres, and after changing one or more wheels.
Before you do, make sure all four tyre pressures are correct for how you are using the car and match the tyre pressure label. The system does not warn you if a pressure is wrong at the time of reinitialisation, because it saves the new pressures as its reference values.

With touch screen:
You do not need to reinitialise the system after fitting or removing snow chains.
If the under-inflation warning lamp flashes and then stays on, together with the Service warning lamp, the system has a fault. Under-inflation monitoring of your tyres is then no longer assured.
Have the system checked by a PEUGEOT dealer or a qualified workshop. After any work on the system, all four tyre pressures must be checked and the system reinitialised.
Your 208 has several visible markings for identifying the car.
Scroll the table sideways.
| Marking | What it is | Where to find it |
|---|---|---|
| A | Vehicle Identification Number (VIN) | Under the bonnet, engraved on the bodywork near the suspension damper mounting |
| B | Vehicle Identification Number (VIN) | On a label on the dashboard, visible through the windscreen |
| C | Manufacturer's label | Tamperproof label on the front pillar, driver's side |
| D | Tyre/paint label | On the centre pillar, driver's side |
The manufacturer's label shows:
The tyre/paint label shows:
Your car may have been fitted from new with tyres with higher load and speed indices than those on the label. This does not affect the inflation pressure.
The lamp stays on when the system detects a drop in pressure in one or more tyres. The alert remains active until you reinitialise the system, so you need to correct the pressures and then reinitialise it.
With the ignition on and the car stationary, press the reinitialisation button for about 3 seconds and release it, or use the Driving/Vehicle menu if your car has a touch screen. Make sure all four tyre pressures are correct before you do this.
The tyre/paint label is on the centre pillar on the driver's side. It shows the tyre pressures unladen and laden, the spare tyre pressure and the paint colour code.
No, the system does not have to be reinitialised after fitting or removing snow chains. You do need to reinitialise it after any pressure adjustment or wheel change.
The under-inflation detection system is a useful backup, but it only works properly if you keep your tyres at the right pressures and reinitialise it each time you adjust them. Check your tyres every month and before long journeys, and you will keep your Peugeot 208 safer and more economical.
If the Service lamp comes on with the under-inflation lamp, see our guide to Peugeot 208 orange warning lights, and for the more urgent warnings, read about Peugeot 208 red warning lights.
