Peugeot 307 I Indicators: Orange Warnings (2002-2005)

Orange warning lamps on your Peugeot 307 flag a fault in one of the car's systems or tell you about something that needs your attention. Many come on briefly when you switch the ignition on and then go out, so watch for any lamp that stays on or lights up while you are driving.

This guide covers the first-generation Peugeot 307 (2002-2005) and is based on the handbook for vehicles produced from 1 July 2004. Some lamps depend on the version, engine or equipment of your car, so you may not see all of them.

Quick Reference

Anti-lock braking system (ABS) warning light

This orange lamp shows the ABS symbol on the instrument panel. It comes on for 3 seconds each time you switch the ignition on. If it stays on, or comes on when you are driving above 8 mph (12 km/h), there is a fault with the ABS. You will also hear an audible signal and see the message "ABS fault" on the multi-function display. Your car still has conventional servo-assisted braking.

What to do:

• Remember that the anti-lock function is not working, although normal servo-assisted braking still is.
• Contact a PEUGEOT dealer.

Electronic stability program (ESP/ASR) warning light

This orange lamp shows the ESP/ASR symbol on the instrument panel. It comes on for 3 seconds each time you switch the ignition on. While you are driving, it flashes when the system is working, and it stays lit when you have switched the system off. If it stays on or comes on while you are driving, together with an audible signal and the message "ESP/ASR system not functioning" on the multi-function display, the system has a fault.

What to do:

If the lamp flashes while you are driving:

• This shows the system is working to help you, so no action is needed.

If the lamp stays lit after you switched the system off:

• This simply confirms the system is switched off.

If the lamp comes on with the "ESP/ASR system not functioning" message:

• Contact a PEUGEOT dealer.

Engine diagnostics warning light

This orange lamp shows the engine diagnostics symbol on the instrument panel. It comes on each time you switch the ignition on. If it lights up while the engine is running, you will hear an audible signal and see a message on the multi-function display that tells you which of two problems it is.

What to do:

If the display shows "Antipollution fault":

• The message means there is a fault in the emission control system.

If the display shows "Unblock diesel filter":

• The message means the particulate emission filter is starting to fill up, which happens after exceptionally long spells of town driving at low speeds or in long traffic jams.

Diesel pre-heat light

This orange lamp shows the diesel pre-heat symbol on the instrument panel. On diesel models it comes on each time you switch the ignition on.

What to do:

• Wait until the lamp goes out before you use the starter.

Water in diesel filter warning light

This orange lamp shows the water in diesel filter symbol on the instrument panel and is fitted depending on the country. When it comes on, you will hear an audible signal and see the message "Water in diesel fuel filter" on the multi-function display. There is a risk of damage to the injection system.

What to do:

• Contact a PEUGEOT dealer as soon as possible.

Passenger air bag disarmed indicator light

This orange lamp shows the passenger air bag symbol on the instrument panel. If the passenger air bag is switched off, the lamp comes on when you switch the ignition on and stays on, and the message "Passenger air bag deactivated" appears on the multi-function display. If the lamp flashes, something is wrong.

What to do:

If the lamp stays on steadily:

• This confirms that the passenger air bag is switched off.

If the lamp flashes:

• Contact a PEUGEOT dealer.

Air bag warning light

This orange lamp shows the air bag symbol on the instrument panel. It comes on for a few seconds when you switch the ignition on. If it lights up while the engine is running, together with an audible signal and the message "Air bag fault" on the multi-function display, there is a fault in the front air bags, or in the side or curtain air bags.

What to do:

• Contact a PEUGEOT dealer.

Low fuel level warning light

This orange lamp shows the fuel pump symbol on the instrument panel. It comes on for 3 seconds when you switch the ignition on. If it lights up steadily while the engine is running, you will hear an audible signal and see the message "Fuel level low" on the multi-function display. If it flashes, the fuel gauge has a fault.

What to do:

If the lamp comes on steadily with the "Fuel level low" message:

• You have enough fuel left for approximately 30 miles (50 km).
• Fill up soon. The tank holds approximately 60 litres.

If the lamp flashes:

• The fuel gauge needle drops to its rest position, below zero, so it will not show your fuel level.
• Contact a PEUGEOT dealer.

If You're Not Sure

If you are not sure which lamp you are seeing, read the message on the multi-function display, as most of these lamps come with one. If you are still unsure, stop somewhere safe, check your handbook and contact a PEUGEOT dealer for advice.

Orange lamps rarely mean you must stop straight away, but they should not be ignored. Note any message on the display and act on it, so a small problem does not turn into a bigger one.
