How to Reset the Maintenance Light on a Citroen C4 Cactus

Model: Citroen Cactus MK 1 - Years 2014-2020
Part: Warning light – error code

The procedure to reset the maintenance light on your C4 Cactus is very simple, but it is essential to remember to reset it only after you have actually performed the vehicle's scheduled maintenance. Sit in the driver's seat, close all doors and windows, insert the key, and keep the ignition off. Press and hold the reset button located at the end of the stalk to the left of the steering wheel (indicator stalk). Turn on the ignition; the "maintenance key" will appear on the dashboard, and the reset indicator will start the countdown. Keep holding the reset button until the countdown is complete and release the button only when the "0" appears on the odometer display. At this point, the maintenance key will disappear; turn off the ignition, and the system reset will be complete.
