I've been driving my Citroen C4L for three or four years now, and I've tried the method to reset the maintenance light several times myself—it's quite convenient and quick. The basic steps are: first, sit in the driver's seat, turn the engine off completely, and turn the key to the OFF position; then press and hold the small mileage reset button on the dashboard, which is usually located near the speedometer; next, turn the key one notch to ACC without starting the engine, and the dashboard will light up; continue holding the button without releasing it for about 10 seconds, and the screen will start flashing numbers or display a countdown, like a little animation. When it stops and shows a steady '000' or resets, you can release the button, and the light will go off. The whole process takes less than half a minute, but you need a good memory and steady hands. Actually, the maintenance light is just a reminder for us to schedule regular maintenance, like changing the oil or checking the brakes. The light going off doesn’t mean you can skip maintenance—it’s best to follow the manual’s guidelines. Last time I got lazy and delayed it once, and I noticed the engine noise got louder—I regretted it immediately, so timely maintenance is crucial. Keeping this habit in daily driving can also extend the car’s lifespan.

As a professional who frequently deals with vehicles, I've seen many Citroën C4L owners make mistakes with the maintenance light reset procedure, but the actual steps are simple and reliable. You need to ensure the car is parked on a safe, level surface with the key completely in the OFF position. Then, press and hold the TRIP button on the dashboard (usually a small round button) without releasing it. Turn the key to the ACC position (first notch), where the dashboard lights up but the engine doesn't start. Keep holding the button for about 5 to 7 seconds until the screen displays a countdown or a small icon flashes. When the countdown ends or a prompt sound is heard, release the button, and the indicator light will reset. Note: Do not perform this operation while driving, as it can be distracting. If there's no response, it may be due to a faulty button or low battery voltage—check the battery or refer to the vehicle manual. The maintenance light is designed to remind you of regular services like oil changes or brake inspections. Resetting it periodically avoids annoying alerts but doesn't mean skipping maintenance—neglecting it could turn minor issues into major problems. I recommend owners develop the habit of checking the manual every six months to confirm procedures—safety first.

To resolve the Citroen C4L maintenance light issue, the quick reset method is to turn off the engine in the driver's seat, turn the key to the ACC position, then press and hold the small reset button on the dashboard. Wait for about ten seconds until the screen changes, then release. The light will go off, and the reminder will disappear. The maintenance light is there to prompt you for servicing, otherwise, it might harm the car. Having driven for years, I know such little tricks can save a lot of hassle.
