What each red warning lamp on your Peugeot 307 (2005-2008) means and what to do, from the central STOP lamp to brake and oil pressure warnings.
Red warning lamps cover the warnings that matter most, from a seat belt reminder to faults where you need to stop the car straight away. When a red lamp comes on while you are driving, read the message on the multifunction display and act on it promptly.
This guide covers the first-generation Peugeot 307, built from 2005 to 2008. It is based on handbook edition ed02-07, which applies to cars produced from 1 October 2007. Some lamps, such as those marked with an asterisk, depend on the version or equipment of your car, so not every lamp here will appear on your dashboard.

| Warning | Urgency | In short |
|---|---|---|
| OPERATION WARNING LIGHTS A permanently lit warning light or one that flashes with the engine running, indicates an operating fault in the relevant unit. Some warning lights may be linked to buzzers and a message on the multi-function display. Do not ignore this warning: contact a PEUGEOT dealer as soon as possible | Get it checked soon | Fault in the related system |
| Central STOP warning light | Information / status | Lights briefly when the ignition switches on |
| Handbrake, low brake fluid level and electronic brake force distribution fault warning light | Stop safely, get help | Handbrake on, low fluid or EBFD fault |
| Seat belt unfastened/not fastened warning light | Action needed from you | Driver's seat belt not fastened |
| Engine oil pressure warning light * | Stop safely, get help | Engine oil pressure warning |
This is the general rule for the warning lamps on your dashboard. If a lamp stays on or flashes while the engine is running, there is a fault in the system it relates to. Some lamps also sound a buzzer and show a message on the multifunction display.
What to do:
This is the red STOP lamp. It comes on for a few seconds every time you switch on the ignition. It also works together with other red lamps, such as the brake warning lamp and the engine oil pressure lamp.
What to do:
This red lamp covers the handbrake, the brake fluid level and the electronic brake force distribution. It works together with the central STOP lamp and comes on for a few seconds each time you switch on the ignition. When it comes on at other times, you will also hear an audible signal and see a message on the multifunction display.
It can mean one of three things. Either the handbrake is applied or has not been fully released, or the brake fluid level has dropped too far, which is the case if the lamp stays on with the handbrake released. Or, if the ABS warning lamp is also on, there is a fault with the electronic brake force distribution.
What to do:
If the handbrake is applied or not fully released:
If the lamp stays on with the handbrake released (low brake fluid level):
If the lamp comes on together with the ABS warning lamp (electronic brake force distribution fault):
This red lamp reminds you about the driver's seat belt. When you switch on the ignition, it comes on if your seat belt is not fastened. With the engine running and the doors closed, it goes out automatically after 30 seconds.
If your seat belt is unfastened while you are driving, the lamp behaves differently depending on your speed. Below 12 mph (20 km/h), it stays on steadily. Above 12 mph (20 km/h), it flashes for two minutes with an audible signal that gets louder, and after those two minutes it stays on until you fasten your belt.
What to do:
If the lamp is on steadily below 12 mph (20 km/h):
If the lamp is flashing with an audible signal above 12 mph (20 km/h):
This red lamp is the engine oil pressure warning, and it works together with the central STOP lamp. If it comes on while the engine is running, you will also hear an audible signal and see a message on the multifunction display. This means you must stop immediately.
What to do:
If a red lamp comes on and you are not sure what it means, stay calm and stop somewhere safe when you can. Read the message on the multifunction display, check the guidance for that lamp above, and contact a PEUGEOT dealer if the lamp tells you to.

Green and blue lamps on your dashboard are information lamps. They tell you that a system or programme is switched on, so they are not normally a sign that something is wrong.
