Reinitialise the Electric Windows

After the battery on your DS 7 Crossback (2017–present) has been disconnected or gone flat, the one-touch function on the windows usually stops working — the glass moves only while you hold the switch. Re-initialising each window restores it in seconds, with no tools.

This is expected after a power interruption and does not mean anything is broken. The window still raises and lowers whenever you hold the switch — only the single-tap travel and the anti-pinch auto-reverse have dropped out. Both come back the instant each window is shown its top and bottom stops again, which is all the short relearn below does.

When You Need This

Each window motor stores its fully-open and fully-closed positions, and that memory is cleared when the 12 V battery is disconnected or runs flat. The fix is a quick relearn from the door switch.

How It Works on the DS 7 Crossback

The motor in each door has a position counter, and the electronics remember where the glass reaches the top seal and the bottom of its travel. Those two saved points drive one-touch and let anti-pinch judge when something is blocking the opening. The data is held only while 12 V power is present, so any loss of battery power wipes it and the car falls back to hold-to-move until you re-teach each window by hand.

Before You Start

• Switch the ignition on so the windows have full power for the relearn.
• Keep the door closed and relearn one window at a time.
• Make sure the opening is clear — no arm, cable or ice on the seal.
• Check the window is not locked out by the driver’s master switch.
• Plan to hold the switch past each end stop — that pause stores the limit.

Re-initialising a Window

1. Pull the switch UP to fully close the window, holding for a moment after it stops, then release.
2. Press the switch DOWN to fully open it, again holding briefly after it stops, then release.
3. Pull UP to fully close once more, holding a few seconds at the top, then release.
4. Check one-touch up and down both work, and repeat for each window that lost the function.

If It Still Won’t Auto-Close

• Hold the switch past the end stop in each direction — the motor must feel the limit to learn it.
• Check the glass runs freely — a sticky channel can stop the relearn completing.
• Do the up-down-up moves in one sequence, without long gaps between them.
• Check the window fuse if a window is dead or crawling; after replacing a blown fuse you must relearn again.
• If the battery was only just reconnected, let the car sit ignition-on for a minute, then repeat.
• Persistent fault? A window-module or switch issue can store a code — look it up on autodtcs.com.

What to Expect After

Once the cycle takes, a single tap again runs the glass fully up or down and the window auto-reverses if it meets an obstruction. The stored positions survive engine-off and future start-ups, so you will not need to repeat this until the next battery disconnection. As each door keeps its own memory, cycle every window that lost the function.

Frequently Asked Questions

Why did my DS 7 Crossback windows stop auto-closing?

The one-touch memory is cleared when the 12 V battery is disconnected or goes flat, so the window loses its stored top and bottom limits. With no reference the car reverts to hold-to-move for safety. Running each window to its hard stop once, in the up-down-up cycle, restores both one-touch and the anti-pinch auto-reverse.

Do I need tools?

No — it is done entirely from the door’s window switch. There is no touchscreen menu, no diagnostic plug and nothing to remove. The only thing that matters is holding the switch a moment past each end stop so the motor can register where fully-up and fully-down actually are.

Which order?

Fully close and hold, fully open and hold, then fully close and hold again. That single up-down-up sequence lets the motor re-reference both ends of the travel in one pass. Keep the door shut so the glass reaches its real top seal, and hold a moment past each stop before releasing.

Do I have to do every window?

Only those that lost one-touch, though it is quick to do them all after a battery job. Each door stores its memory separately, so cycling every window avoids finding out later that a rear or passenger window never re-learned its travel.

Will anti-pinch work before I relearn?

The auto-reverse that protects fingers relies on the same learned travel data, so it is effectively out until the relearn is done. That is one reason the car drops to hold-to-close — it keeps you watching the opening. Complete the up-down-up cycle and the anti-pinch protection returns with the one-touch.

It still won’t work — now what?

Repeat the cycle, holding each end stop and keeping the door shut, and confirm the glass runs freely in its channel. Check the window fuse if a window is dead or slow. If it still fails, a module or switch fault may be stored — look up the code on autodtcs.com.
