What is the method to reset the maintenance light on a C5?

[StRylee]

The method to reset the maintenance light on a C5 is: 1. Turn off the ignition switch of the C5; 2. Press and hold the check maintenance mileage reset button; 3. Start the car, and the maintenance light will reset, then you can release the button. Taking the 2019 C5 as an example, it belongs to the mid-size car category, with body dimensions of: length 4825mm, width 1860mm, height 1480mm, wheelbase of 2815mm, fuel tank capacity of 70l, and trunk capacity of 439l. The 2019 C5 is equipped with a 2.0T turbocharged engine, with a maximum horsepower of 167ps, maximum power of 123kw, maximum torque of 245nm, paired with a 6-speed automatic manual transmission.

I remember being quite nervous the first time I reset the maintenance light on my C5, worried I might mess something up. My car was a 2014 model, and the steps were: After turning off the engine, press and hold the small round button on the left side of the dashboard, then turn the key to the ignition position (without starting the engine). At this point, the dashboard will suddenly light up—keep holding the button. After about ten seconds, you'll see the maintenance countdown numbers rapidly decrease until they reset to zero, then you can release the button. Turn off the ignition and restart the car, and the light will be gone. However, I should mention that this method might not work for models after 2015. It's best to check the manual in the glovebox or ask the technician to adjust it during your next service. If you do it yourself, make sure the oil and filter have already been changed—after all, the purpose of the maintenance light is to remind you not to exceed the service interval, right?

I've helped friends reset the maintenance reminder light three times already. Here's the procedure: With the engine off, press and hold the trip reset button on the left side of the dashboard while turning the key to the ACC position (just enough to power the radio). Keep holding when all warning lights illuminate on the instrument panel. When the maintenance indicator starts flashing, continue holding for about 7-8 more seconds. The procedure is complete when the wrench symbol disappears from the display. Two important notes: The steering wheel must be in the straight-ahead position or it might fail; Newer models with digital instrument clusters require finding the reset option in the vehicle settings menu. Always confirm maintenance has been completed before attempting this, otherwise it's wasted effort.
