If your Hyundai Kona Mk1 (OS, 2017–2023) has the electric glass sunroof and its one-touch open/tilt has stopped working — typically after a battery disconnection, a flat battery or a fuse change — the roof needs re-initialising so it relearns its end positions. Hyundai lists this as a required step after reconnecting the battery. It is a quick no-tools job from the cabin. This guide shows how.
Why the Sunroof Needs Re-initialising
The sunroof motor stores its fully-closed, tilted and fully-open positions so the one-touch and anti-trap (pinch protection) functions work. Losing power clears that memory — the roof still moves while you hold the switch, but the automatic operation stops until it is re-taught.
How to Re-initialise the Kona Sunroof
Do this with the ignition on (engine can be off):
- Turn the ignition on.
- Press and hold the sunroof switch until the roof is fully closed, then release the switch.
- Press and hold the sunroof CLOSE switch again for about 10 seconds — the sunroof tilts and moves slightly.
- Keep holding (or press and hold the close switch once more) — the roof now moves in steps for about 10–20 seconds, running through tilt down → slide open → slide close automatically.
- When it completes the cycle and stops, the initialisation is done. Release the switch.
- Test the one-touch function — a single press should now tilt/open the roof automatically.
If It Still Won’t Operate Automatically
- Repeat the procedure — the hold steps must be long enough for the roof to run the full learn cycle.
- Let the automatic cycle finish — don’t release the switch until the roof has stepped through tilt/open/close and stopped.
- This is the same step Hyundai lists after reconnecting the battery, so if you have just done battery work, run it alongside the window initialise.
Frequently Asked Questions
Why did my sunroof stop auto-opening after a battery change?
Disconnecting the battery wipes the roof’s stored end positions, so one-touch and anti-trap switch off until you re-teach it with the routine above.
Do I need any tools?
No — just the overhead switch and the ignition on. No diagnostic equipment is required.
The roof reverses when closing — what’s wrong?
That is the anti-trap protection reacting because the limits aren’t learned. Re-run the initialisation and make sure nothing is obstructing the channel.
My Kona doesn’t have a sunroof — does this matter?
No — only cars optioned with the electric glass sunroof need this step. If yours has none, skip it.
