This lamp shows the open door symbol. It stays on with a message telling you which door is open, and how it behaves depends on your speed. Below 6 mph (10 km/h), it means a door or the boot is still open. Above 6 mph (10 km/h), a warning sound comes on as well.
What to do:
Below 6 mph (10 km/h):
- Close the door or boot shown in the message.
Above 6 mph (10 km/h):
- The lamp stays on with the message and a warning sound.
- The handbook gives no separate instruction for this case.
Seatbelt(s) not buckled / unbuckled

This lamp shows the seat belt symbol. It comes on, then starts flashing with a warning sound that gets louder. It means a seat belt has not been fastened or has been unfastened.
What to do:
- Pull the belt strap out and push the tongue into the buckle.
Battery charge

This lamp shows the battery symbol. When it stays on, there is a fault in the battery charging circuit, for example dirty or loose terminals or a slack or cut alternator belt.
What to do:
- The lamp should go off once the engine has started.
- If it stays on, contact a PEUGEOT dealer or a qualified workshop.
Engine oil pressure

This lamp shows the oil can symbol. When it stays on, there is a fault in the engine lubrication system.
What to do:
- Stop as soon as it is safe to do so.
- Park and switch off the ignition.
- Contact a PEUGEOT dealer or a qualified workshop.
Min. fuel level

This lamp shows the fuel pump symbol. It stays on with the fuel gauge needle in the red zone. When it first comes on, about 7 litres of fuel are left in the tank and you are starting to use the reserve.
What to do:
- Refuel as soon as possible so you do not run out of fuel.
- The lamp will come on each time you switch on the ignition until you add enough fuel.
- Never keep driving until the tank is empty, as this could damage the emission control and injection systems.
If You're Not Sure
Some lamps come on for a few seconds when you switch on the ignition and should go off once the engine starts. If a red lamp stays on, check the message shown with it before you move off. If you are still unsure what it means or have any problems, contact a PEUGEOT dealer or a qualified workshop.
Red lamps are there to get your attention, so it is always worth acting on them rather than waiting. Keep your handbook in the car and use this guide alongside it so you know what your Peugeot 508 is telling you.
