The flagship DS 9 (X) 2021-Present is a large, luxury-leaning saloon from Citroën’s premium DS sub-brand, built on the EMP2 platform and offered with plug-in hybrid powertrains and DS Active Scan Suspension. Its abundance of electronics means that after any service the car keeps displaying the previous maintenance status until each system is reset. Owners commonly need the oil service reset, the broader service reminder reset, a TPMS reset after tyre work, and on the PHEV models confirmation of the 12V battery after replacement. The steering angle reset can also apply following suspension or alignment work. Use the guides below to find the precise reset your DS 9 requires.
