Peugeot Warning Lights

It's vital to know what a warning light means when it pops up on your dashboard. Whether it's red, amber, or green, you need to know what your car is trying to tell you so that you can get any problems fixed. If you're the owner of a Peugeot vehicle, there are some important symbols that you should be able to recognise so that you can solve the issue.

Red warning lights indicate issues that should be addressed ASAP, although they are not necessarily a serious fault. For example, they include seat belts and door open symbols. Amber warning lights indicate a problem that needs to be corrected but not urgently, while green lights are usually simple indicators.

If your car needs to be checked right away, book a service with Swansway Motor Group, and we'll diagnose and repair the problem.



Red Peugeot Warning Lights

Engine oil level/oil pressure light

The oil pressure or oil level lights indicate that there is a fault in the engine's lubrication system. You might see these lights if the oil temperature is too high, or the oil level or pressure is too low. In some models, such as the Peugeot 108, you might also see the STOP light. If the oil pressure/level light is red, you should pull over as soon as it is safe to do so and turn off your engine.

Brake warning light

A brake warning light might indicate an issue with the braking system or parking brake. This could be due to several issues, including the brake fluid level being too low, a fault in the braking system, or the parking brake being applied or not properly released.

Parking brake warning light

In some models, such as the Peugeot 208, there will be a separate parking brake warning light. If it is fixed, it indicates that the parking brake is applied or not properly released. In electric parking brakes, the light may also flash, which shows that there is a fault in the parking brake application/release. After stopping your car, you will need to either engage a gear (with a manual gearbox) or select mode P (automatic gearbox) before calling a garage/workshop

Engine coolant temperature warning light

This light can be fixed or flashing in some models, or it might have display blocks lit in red on the matrix instrument panel. If it is flashing (such as in the Peugeot 108), it indicates that the engine coolant temperature is rising. If it is fixed, the temperature of the cooling system is too high.

Stop warning light

The stop light might simply say STOP, or it might be a warning triangle with an exclamation mark. It can be accompanied by another light that further indicates what the problem is. Stop as soon as it is safe to do so and book your vehicle in for a service.

Battery charge warning light

This light turns on for a short time when you first turn on your car. However, if it stays illuminated, this means that there is a fault in the battery charging circuit. The issue may be solved by cleaning the battery terminals, but if this doesn't work, you should book your car in for a checkup.

Engine auto diagnosis system light

The engine self-diagnostics system light indicates that a major fault in the engine has been detected when it is illuminated in red. It can also be amber, flash, and may or may not have an exclamation mark inside it. When this light is visible, you need to get your car looked at right away.

Seat belt light

The seatbelt light will show when a seat belt has not been fastened or has been unfastened. Check that seat belts are fastened to get the light to turn off again.



Amber Peugeot Warning Lights

ABS warning light

The amber ABS light will be illuminated if the anti-lock braking system has a fault. Conventional braking is still working, making it possible to continue to drive carefully at a moderate speed. However, you should take your car to be looked at as soon as possible

Brake + ABS warning light

An amber ABS light may come on along with the brake light if the electronic brake force distribution is faulty. You should stop your car and book an appointment for repairs.

Service light

The service light might be temporarily on or can remain on. It may also be accompanied by a message. If it is on temporarily, accompanied by a display message, there are one or more minor faults that have no relevant warning light. If it's fixed, there are one or more major faults. When accompanied by the message "parking brake fault", the electric parking brake cannot be released automatically. You might be able to deal with some simple issues yourself, but see a mechanic for anything else. If you have a Blue HDi engine, you might also see the service light with a spanner symbol. This means that you need to get your car serviced right away.

Particle filter (diesel)

The amber particle filter light in cars with diesel engines is accompanied by a noise and a message telling you the issue. It will come on either when the particle filter is nearing saturation, or there is a low level of additive in the tank. If the filter is nearing saturation, it can be regenerated by driving at a speed of at least 37mph until the light turns off. If the additive level is low, it needs to be topped up, and you should have your car serviced.

Low fuel level

The low fuel level light will come on at different points, depending on the model. There will be approximately five or six litres of fuel left when it comes on, accompanied by an audible signal. You should fill up right away to avoid driving until the tank is empty.

AdBlue light (plus service light, plus engine diagnostic light)

The AdBlue light will indicate when the AdBlue needs to be topped up to avoid engine starting problems. In some models, such as the Peugeot 508, this light might say UREA. The light might be solid, or it can also flash. When a solid AdBlue light is accompanied by the service light and engine diagnostic light, it means a malfunction involving SCR emissions has been detected. It will disappear when exhaust emissions return to normal. If the AdBlue light is flashing with the other two symbols displayed, with an audible signal and message indicating the driving range, you need to get your car seen without delay. If the message says that starting has been prevented, you need to contact a mechanic.

Foot on clutch pedal light

This light might be amber or is sometimes black. It indicates that the car can't be changed to start mode because the clutch is not fully depressed. Once it is, the car will be able to move into start mode.

Airbag fault light

There are two amber airbag lights that might light up on a Peugeot car's dashboard. The first is the airbags light that indicates that one or more of the airbags or seat belt pretensioners are faulty. This requires your car to be serviced so the fault can be fixed.

Passenger seat airbag light

The second airbag light is for the front passenger seat, indicating whether it is on or off. When it is on, it is unsafe to install a rear-facing child's seat on the front passenger seat.



Green Peugeot Lights

Start and stop light

This light will be fixed when the vehicle stops and has been put into stop mode. If it's flashing, it means that stop mode is temporarily unavailable, or start mode is automatically triggered.

Lamp lights

These lights tell you when the fog lamps, side lamps, and headlights are on. Blue headlight symbols show that the main beam headlights are on.
