This guide shows how to top up the AdBlue additive in the Peugeot 308 Mk2. To perform the top-up, open the boot of the vehicle and remove the trim panel of the compartment to reveal, in the right corner, the tank cap. Clean the area of any debris before opening the cap. Top up with the correct amount of fluid as specified in the relevant section of the vehicle's user manual.

Once the operation is complete and the tank is closed, the additive top-up warning will turn off on the instrument panel.

Never allow the additive to reach the minimum level to avoid blocking the vehicle.
