When the AdBlue fluid level drops below the reserve level, a sensor alerts the onboard computer to signal this with one or two warning lights on the instrument panel. In this case, the first thing to do is, of course, top up the fluid until the tank is full.

Next, turn on the ignition and check if the warning lights have turned off. If not, simply turn off the ignition and wait a few seconds to allow the system to reset. If it does not work on the first attempt, repeat the process multiple times until the reset is successful.
