If the tyre-pressure warning has appeared in your DS 7 Crossback (2017–present) after you’ve adjusted the pressures or changed a wheel, you need to store the new pressures as the reference — done through the touchscreen on the DS. Here’s how.
When to Reset
- After checking or adjusting the tyre pressures.
- After changing one or more wheels or tyres, or fitting winter wheels.
Resetting the System
- Set all four tyres to the correct cold pressures (placard in the driver’s door shut) — the system stores whatever is set.
- On the touchscreen, open Driving assistance (or the vehicle menu) and select Tyre pressure.
- Choose reset / initialise and confirm with the pressures correct.
- The current pressures become the new reference and the warning clears.
If the Warning Stays On
- Recheck every tyre — one below spec keeps the warning on and blocks the reset.
- Reset with correct, cold pressures only — resetting on a soft tyre teaches 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 7 Crossback?
Set all tyres correctly, then on the touchscreen go to Driving assistance > Tyre pressure and confirm the reset.
Is there a physical button?
The reset is via the touchscreen on this model; set the pressures first, then confirm in the menu.
Why won’t the warning clear?
Usually a tyre still below spec, or the reset was done with warm/incorrect 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.
