If the lamp shows that at least one rear passenger has unfastened their seat belt:

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 read the message on the screen, as it will help you identify the fault. Then check your handbook, and if you are still unsure or the problem continues, contact a PEUGEOT dealer or a qualified workshop.
Some warning lamps come on for a few seconds when you switch on the ignition and should go off once the engine has started. If a red lamp stays on before you move off, check what it means first. Red lamps are there to protect you and your RCZ, so always act on them promptly.
