If the tyre-pressure warning has come on in your DS 3 Crossback (2019–present) after you’ve checked or adjusted the pressures, or fitted different wheels, you need to tell the system the new pressures are correct. On the DS that’s done through the touchscreen. Here’s how.
When to Reset
- After checking or adjusting the tyre pressures.
- After changing one or more wheels or tyres, or swapping to winter wheels.
Resetting the System
- Set all four tyres to the correct pressures first (the placard is in the driver’s door shut) — the system stores whatever is set, so they must be right.
- On the touchscreen, open Driving assistance (or the car/vehicle menu) and select Tyre pressure.
- Choose the reset / initialise option and confirm (‘Yes’) with the pressures correct.
- The system stores the current pressures as the new reference and the warning clears.
If the Warning Stays On
- Recheck every tyre — one still below spec keeps the warning on and blocks the reset.
- Reset only with correct, cold pressures — resetting with a soft tyre teaches the system the wrong value.
- Still showing with correct pressures? A sensor or system fault may be involved — look up the code on autodtcs.com.
Frequently Asked Questions
How do I reset the tyre pressure warning on a DS 3 Crossback?
Set all tyres correctly, then in the touchscreen go to Driving assistance > Tyre pressure and confirm the reset.
Is there a button instead of the screen?
The reset is done through the touchscreen menu on this model; set the pressures first, then confirm.
Why won’t the warning clear?
Usually a tyre still below spec, or the reset was done with incorrect/warm pressures.
Do I need a tool?
No for a normal reset; a tool is only needed if a sensor is replaced and must be matched.
If the warning came on with other lights, decode the code on autodtcs.com.
