Red warning lights on the Peugeot 307 CC (2003-2005) explained: what each lamp means and what the handbook tells you to do when one comes on.
A red warning lamp on your dashboard points to something serious or something that needs your attention straight away. Many of them come with an audible signal and a message on the multi-function display, and several are linked to the central STOP warning light.
This guide covers the red warning lamps on the Peugeot 307 CC, based on handbook edition ed02-04 for vehicles produced from 1 July 2004. Some lamps depend on the version or equipment of your car, so not every one may appear on yours.

This lamp is the main STOP warning on the instrument panel. It comes on each time you switch on the ignition. It works together with the engine oil pressure, low coolant level, brake fluid level and electronic brake force distribution fault warning lights, as well as the coolant temperature and engine oil temperature gauges. If the coolant temperature is too high, it flashes with an audible signal and the message "Engine coolant temperature too high". If the engine oil temperature is too high, it flashes with an audible signal.
What to do:
If it flashes while the engine is running:
This is the red engine oil pressure lamp, and it is linked to the central STOP warning light. If it comes on while the engine is running, you will also hear an audible signal and see the message "Oil pressure insufficient" on the multi-function display.
What to do:
This is the red low coolant level lamp, fitted depending on the engine, and it is linked to the central STOP warning light. It comes on for about 3 seconds each time you switch on the ignition. If it lights up to warn you, it comes with an audible signal and the message "Top up engine coolant level" on the multi-function display.
What to do:
This red lamp covers both the handbrake and the brake fluid level, and it is linked to the central STOP warning light. It comes on each time you switch on the ignition. When it lights up as a warning, you will hear an audible signal and see a message on the multi-function display telling you the cause.

If the message reads "Handbrake on":
If the message reads "Brake fluid level low" and the light stays on even with the handbrake released:
If the message reads "Braking fault" and the ABS light comes on at the same time:
This is the red battery charge lamp. It comes on each time you switch on the ignition. If it comes on while the engine is running, it comes with an audible signal and the message "Battery charge fault" on the multi-function display. The cause can be a fault in the charging circuit, loose battery or starter terminals, a cut or slack alternator belt, or an alternator fault.
What to do:
This red lamp covers the air bags and the pop-up roll-over hoops. It comes on for a few seconds when you switch on the ignition. If it lights up with the engine running, you will hear an audible signal and see a message: "Air bag fault" means a fault in the front or side air bags, and "Roll-over hoops fault" means a fault in the pop-up roll-over hoops in the rear head restraints.
What to do:
This is the red seat belt reminder lamp. With the engine running, it comes on with an audible signal when the driver's seat belt is not fastened. If the belt is still not fastened, the light stays on and the signal gets louder.
What to do:
If a red lamp comes on and you are not sure what it means, stay calm, stop somewhere safe and check the message on the multi-function display. Your handbook is the best place to confirm what the light is telling you.
