Press the first button below the front display (TRIP), and the mileage will be immediately reset to zero. First, navigate the trip computer to the interface that needs to be reset, then press the button at the top of the wiper for more than 5 seconds, and the mileage will be immediately reset to zero. Hold down the button below the front display without releasing, turn to the ON position, a countdown will appear, and once it ends, the mileage will be automatically reset to zero.

I just figured out how to reset the light on my Citroën C5, and it's actually quite simple. First, turn off the engine and the ignition switch, then locate the small button on the dashboard—usually the one for resetting the odometer—and hold it down. Next, turn the key to the ACC position (where the engine isn't started but the electronics are powered), and continue holding the button for about 10 seconds until the maintenance light goes off, indicating the reset is complete. This method works for most C5 models, such as the newer ones from 2010 onwards. However, older models or higher trim versions might have the button in a slightly different location—older versions might have it on the left side of the dashboard, so make sure you press the right one. If it doesn’t work on the first try, repeat the process or check the user manual. After resetting, note down the current mileage to plan your next service. Regularly resetting the light ensures accurate reminders, helping you avoid missing maintenance and extending your car’s engine life.

My Citroen C5 always has that annoying light on after every service, so I learned how to reset it myself. Here are the specific steps: After turning off the engine, press and hold the reset button on the dashboard, then turn the key to the half-on position (power on but engine not started). Hold for about 10 seconds until the light goes off. My car is a 2015 model, and the button is next to the steering wheel—it works every time. Beginners might worry about pressing the wrong spot or not holding long enough, but with a few tries, you'll get the hang of it. After resetting the maintenance light, driving feels more reassuring because it accurately reminds you of the next service time, preventing oil burning or minor issues. For different models like those with navigation, the steps are similar, but if you can't find the button, searching for a video online is easier than running to the shop.

Clearing the C5 service light is straightforward: After turning off the ignition, press and hold the reset button on the dashboard. Turn the key to the ACC position without starting the engine. Hold for about ten seconds until the light goes off, indicating the reset is complete. Button locations vary slightly by model year—for example, base models have it below the instrument cluster. It’s quick and easy. After resetting, the service reminder restarts, ensuring you don’t miss critical maintenance to keep your engine healthy. When in doubt, check the manual.

I believe the light reset must be done accurately as it helps prevent engine issues and maintains long-term vehicle performance. Method: Turn off the ignition, hold the reset button, turn the key to the ACC position, press for ten seconds until the light goes off. For different models like the 2008 older version, the button is located on the left side of the dashboard with similar steps. I've experienced that if the light stays on, it affects driving, but after resetting, it feels much better. Remember to note the current mileage after the operation and plan the next maintenance. Safe driving relies on these small maintenance tasks. If the button is hard to find, ask a friend or check the manual.

The C5's maintenance light system is practically designed, with resetting accurately indicating service intervals. Reset method: Turn off the ignition, hold the button, switch to ACC mode for ten seconds, and the light goes off—done. Having driven the C5 for years, these steps are universally applicable. The advantage is that the light doesn't distract, making long drives more reassuring. Variants like high-end models follow the same button procedure. Resetting after regular maintenance ensures the engine remains unworn. This small routine extends the car's lifespan and saves on repair costs.
