Reinitialise the Electric Sunroof

Last updated: June 7, 2026

If the electric sunroof on your DS 7 Crossback (2017–present) has stopped working with one touch — usually after a battery disconnection or flat battery — it needs re-initialising so it relearns its end positions. It’s an owner job done from the sunroof switch in about a minute.

When You Need This

The sunroof loses its calibration when the 12 V battery is disconnected or goes flat, leaving the panel working only while you hold the switch. Re-initialising restores normal one-touch operation.

Re-initialising the Sunroof

1. Switch the ignition on.
2. Press and hold the sunroof CLOSE switch until the roof is fully closed — it will tilt and move slightly. Keep holding for 1 second, then release.
3. Wait 2 seconds.
4. Press and hold the CLOSE switch again — the roof completes a full open/close cycle. Hold for about 2 seconds, then release.
5. The sunroof is initialised.

If It Won’t Initialise

• Hold the switch for the full times stated — the roof must reach and hold its end stops.
• Clear debris from the seals and track so it can run fully.
• Still faulty? A sunroof-module issue can store a code — look it up on autodtcs.com.

Frequently Asked Questions

Why did my DS 7 Crossback sunroof stop working with one touch?

Its calibration is lost when the battery is disconnected or goes flat — the re-initialisation restores it.

Do I need tools?

No — it’s done from the sunroof switch with the ignition on.

What if it doesn’t complete the cycle?

Repeat the sequence, making sure you hold the switch until the roof reaches each end stop.

Does this apply to the panoramic roof?

Yes — the same re-initialisation applies to the DS 7’s electric sunroof.
