Reset the Tyre Pressure Monitor (TPMS)

The Renault Megane Mk4 (2016–2022) learns a reference set of tyre pressures, so after you inflate or change a tyre you re-learn them. You can do it with the dashboard button or through the display menu. The warning light coming on isn’t a fault in itself — it’s the car telling you the current pressures no longer match the stored reference. Here’s how to clear it.

How the System Works on the Megane

Rather than reading a pressure value at each wheel, the Megane Mk4 monitors the tyres and stores a reference that it compares against as you drive. That’s why the fix is a ‘learn’ rather than a value reset: you set the pressures correctly, tell the car to memorise them, then drive so it can lock in the new baseline. If you skip the learn, the car keeps comparing against the old reference and the warning can stay on or come back.

Set the Pressures First

Inflate all four tyres cold to the figure on the driver’s door-pillar label, then re-learn.

First, a Few Checks

• Check pressures cold — before driving, or after the car has stood a few hours. A warm tyre reads high and throws the baseline off.
• Set every corner to the door-pillar figure, adjusting for a full load if the label lists one.
• Switch the ignition on for the learn; you don’t need the engine running to start it.
• Have a short, uninterrupted drive in mind so the learn can complete in one go.

Method 1 — Dashboard Button

1. Switch the ignition on.
2. Press the display button repeatedly until ‘Learning the tyre pressure’ appears.
3. Press and hold the button for 3 seconds — a confirmation message shows.
4. Drive for about 5 minutes to complete the learn.

Method 2 — Display Menu

On the multifunction display, select ‘Vehicle’, then ‘Tyre pressure’, and confirm the re-learn.

If the Light Stays On

• Re-check every tyre — one low corner keeps the warning on, and it’s often the one you didn’t think to check.
• Always re-learn after inflating or a wheel change. The old reference no longer matches until you store the new one.
• Complete the drive — if you stop too soon the learn may not finish and the warning returns.
• On a cold morning pressures drop; top up to the label figure and re-learn rather than chasing a warm reading.
• A space-saver or non-matching spare can trigger the warning until the normal wheel is refitted.
• If one corner keeps falling after you’ve set it, suspect a slow puncture or a leaking valve.
• New sensors fitted at a tyre shop need calibrating with a tool before the car will read them.

Once It’s Done

Once you’ve stored the reference and driven a few minutes, the warning goes out and stays off for the trip. It won’t always clear the instant you confirm — the car needs the short drive to be sure the pressures hold. If the light returns on the next cold start, that’s normal seasonal loss: re-inflate to the label figure and learn again.

Frequently Asked Questions

How do I reset the tyre pressure light on a Renault Megane?

Ignition on, press the display button to ‘Learning the tyre pressure’, hold 3 seconds, then drive 5 minutes — or use Vehicle → Tyre pressure in the menu. Always set all four tyres to the correct cold pressures first so the baseline it stores is right.

Do I need a tool?

Not for a normal re-learn — the button or menu method plus a short drive is all it takes. A tool is only needed if new sensors were fitted, so their IDs can be registered to the car. If a fresh sensor was installed and the car won’t read it, that’s a calibration job for a tyre shop.

Why does the light come on in cold weather?

Pressures drop as temperature falls, so a tyre set correctly in mild weather can read low on a frosty morning. Top every corner back up to the label figure while the tyres are cold, run the learn, and the warning should stay off unless a tyre is genuinely leaking.

It came on after a wheel change — why?

The reference moved. Rotating, swapping to winter wheels, or refitting after a repair changes what each sensor reports, so the car no longer matches its stored baseline. Re-run the learn so the new pressures become the reference and the warning clears.

Which method should I use?

Either works — the dashboard button is quickest if your car shows the ‘Learning the tyre pressure’ prompt, while the menu route (Vehicle → Tyre pressure) is clearer on cars with the larger display. Both do the same thing: memorise your corrected cold pressures as the new reference before you drive.
