How to reset the maintenance light on the Citroen New C5?

[Priscilla]

Citroen New C5 maintenance light reset method is as follows: 1. First, turn off the ignition switch of the C5, then press and hold the "CHECK" maintenance mileage reset button. 2. Turn on the ignition switch, and you will see the odometer start counting down. 3. When the display shows "Initialization completed" or "=0", you can release the button, and the maintenance indicator light will be successfully reset. 4. Another method is to go to an authorized Citroen service center for maintenance, where the maintenance personnel will use a car computer detector to reset the maintenance light after the service.

Having driven the Citroën New C5 for several years, I can confirm that resetting the maintenance light isn't complicated—it mainly relies on button combinations. After each service, I first turn off the engine and rotate the key to the OFF position. Then, I locate the odometer reset button on the dashboard and hold it down without releasing, while slowly turning the key to the ACC position (the first notch when inserting the key). Maintain the press for about 10 to 15 seconds; if the indicator light flashes or turns off, the reset is successful. This method helps avoid false reminders—it's annoying when the light stays on, but resetting it brings peace of mind while driving. I recommend keeping the owner's manual handy, as its step-by-step diagrams are clearer. If the method fails, it might be due to model variations—post-2019 models may require pressing an additional button. As a last resort, try the vehicle settings menu or seek help on professional forums. DIY solutions save time and money, and developing good habits like this makes car maintenance more thoughtful.

As a newbie who just got a Citroen New C5, I was stunned when the maintenance light came on. Later, I searched online for solutions and tried one. In short, after turning off the car without ignition, with the key in the OFF position, press and hold the small round button on the dashboard (usually for adjusting the clock), then turn the key to the ACC position and wait patiently for more than 10 seconds. The light will flash and reset. The first time I was so nervous I almost let go, but actually, taking it slow is fine. Remember, the button position might vary slightly for different model years, so checking the car manual is the safest bet. After resetting, don’t forget to verify if the maintenance is done—the light is just a reminder. Doing it yourself is safe and convenient, but if you can’t manage, just ask the 4S store for help; it’ll take a few minutes and won’t affect your trip.

I love tinkering with cars, and I've researched various methods to reset the maintenance light on the Citroën New C5. The standard procedure is to turn off the engine, press and hold the reset button, turn the key to ACC, and wait for the reset. However, the button layouts differ between the 2017 and 2021 models—some are on the steering wheel. Some even use an OBD diagnostic tool for a one-click solution, which is more advanced. I think this system is thoughtfully designed; resetting is simple, but you must ensure the maintenance is truly completed without skipping inspections. Test-driving to verify the light is off is sufficient to avoid mistakes. DIY is fun—combine it with the manual and try some tricks to enrich your car life and save money.
