Lost the one-touch (auto up/down) on your Cupra Formentor (KM, 2020–present) after a flat or disconnected battery? The window motor has simply forgotten its top and bottom limits. This is normal after any loss of power and is not a fault — you re-teach the limits by hand in under a minute, with no tools.
What Happened
Each door’s window controller stores the fully-closed point so one-touch can stop neatly at the seal and the anti-trap can react. Cut the power — a flat battery, a jump-start, or unplugging the battery for other work — and that memory clears, leaving hold-to-move only. Nothing has broken; the controller has just lost its reference points and needs them taught again.
How It Works on This Model
One-touch depends on the controller knowing exactly where the top and bottom of travel are. Holding the switch past the stop at each end re-logs those limits. The same stored range drives the anti-trap safety, which reverses the glass if it meets resistance on the way up — so until you relearn, both the auto stop and that protection stay inactive on the affected window.
Getting Ready
- Ignition on so the windows have full power for the whole learn.
- Make sure the 12 V battery is healthy — a mid-cycle voltage dip can spoil it.
- Close the door you’re working on and keep fingers clear of the glass.
- Work on one window at a time, each from its own switch.
Re-teaching a Window
- Door closed, ignition on.
- Lift the switch to close fully and keep holding ~2–3 seconds past the stop.
- Let go, then press down to open fully, pausing at the bottom.
- Lift again to close fully, holding a couple of seconds at the top.
- Release and check one-touch both ways.
Do each affected window from its own switch.
If It Won’t Stay Set
- Hold longer at the top so the controller logs the closed limit before you release.
- Shut the door fully — an ajar door can leave the switch unpowered on some setups.
- Confirm the battery is healthy during the learn; retry after a run if you’ve just jump-started.
- Check the window fuse if a single door has no auto function at all.
- Run the full cycle — close, open, close — if one-touch only works one way.
- Persistent failure after a clean relearn can point to a motor or switch fault; look up any stored code on autodtcs.com.
What Happens Next
Once taught, a single tap runs the glass fully up or down again, and the anti-trap reverse comes back with it. The calibration is held permanently and only needs redoing after the next battery disconnect or flat. If several windows lost their auto function, expect the whole car to take just a minute or two.
Frequently Asked Questions
Why did my Formentor windows stop auto-closing?
A battery disconnect, jump-start or flat battery cleared the travel limits each door controller stores. Without them the motor no longer knows where the fully-closed point is, so it only moves while you hold the switch. Re-initialising each window teaches those limits again and restores one-touch.
How do I reset the auto window on a Cupra Formentor?
With the ignition on and the door closed, lift the switch to close the window fully and hold two to three seconds past the top. Then press down to open fully, and lift once more to close fully, holding briefly at the top. Release and test one-touch both ways.
Do I have to do every window?
Only the one-touch ones that lost their auto function, and each from its own switch. The controllers are separate per door, so teaching the driver’s window does nothing for the rest. Work round the affected doors until each auto window stops and starts on a single tap.
Do I need any tools?
None. The relearn is done entirely at the door switches — no scan tool, menu or fuse-pulling. You’re just holding the switch through a full close, full open and full close again so the controller can re-log where the ends of travel are.
Why does one-touch only work in one direction?
Usually one end didn’t register — the switch was released before the controller logged that limit. Run the sequence again and hold a clear two to three seconds at both the fully-closed and fully-open positions so both ends of travel are learned properly.
Could a weak battery be the real cause?
Yes. A tired 12 V battery can dip during the learn so the calibration doesn’t stick, or the memory can clear again when the car sits. If windows keep losing their auto function without a disconnect, have the battery and charging checked before assuming a motor fault.
