Peugeot 108 I Indicators: Red Warnings (2015-present)

Red warning lamps on your Peugeot 108 tell you about a malfunction or show the status of a system. If one comes on while the engine is running or you are driving, it points to a fault that needs looking into. Check any message on the screen and the description of that lamp below. Some red lamps come on for a few seconds when you switch the ignition on and should go out as soon as the engine starts. That is normal.

This guide covers the first-generation Peugeot 108 (2015-present) and is based on handbook edition ed01-18, which applies to cars produced from 2 May 2018. Some lamps flash as well as staying on, some come with a warning sound or a screen message, and some depend on your car's version or equipment, so not every lamp here will appear on your car.

Low fuel level

This lamp shows the fuel pump symbol. It stays on, with a warning sound, and when it first comes on you have about 5 litres of fuel left in the tank as a reserve.

What to do:

• Refuel without delay so you do not run out.
• Never drive until the tank is completely empty, as this could damage the emissions and injection systems.

Dynamic stability control /Traction control (DSC)

This lamp shows the stability control symbol. When it flashes, DSC/TRC is working because the car has lost grip or is going off its line. When it stays on, the DSC/TRC systems are faulty.

What to do:

If the lamp is flashing:

• No action is needed, the system is doing its job.

If the lamp stays on:

• Have the systems checked by a qualified professional.

Dynamic stability control (DSC)

This lamp shows the DSC off symbol. It stays on when the button has been pressed for more than 3 seconds with the car stopped, which switches off both traction control (TRC) and dynamic stability control (DSC).

What to do:

• You can fit a rearward-facing child seat in the front passenger seat.
• Do not do this if the airbag warning lamp is on, as that means there is an airbag fault.

Rear foglamp

This lamp shows the rear foglamp symbol. It stays on to confirm that the rear foglamp is switched on.

What to do:

• No action is needed, this simply confirms the rear foglamp is on.

If You're Not Sure

If a red lamp comes on and you are not sure what it means, stay calm, stop somewhere safe and check any message shown on the screen alongside the lamp. If you still have doubts, contact a qualified professional for help rather than carrying on with your journey.

Most red lamps on your Peugeot 108 are either a quick reminder, like a seat belt or open door, or a sign that something needs attention straight away. Knowing which is which helps you react calmly and keep your car in good shape.
