Last updated:
If the tyre-pressure warning has come on in your Porsche 718 Boxster or Cayman (2016–present) — the 982 — after you’ve adjusted the pressures or changed a wheel, you handle it through the central display (PCM). The 718 uses sensors in the wheels and runs staggered tyres (wider rears).
After Adjusting Pressures
For a simple top-up, no manual reset is needed — just drive the car and the system re-reads the corrected pressures.
After Changing Wheels or Tyres
- Set the tyres to the correct cold pressures (fronts and rears differ).
- On the PCM / multifunction display, open the tyre-pressure page.
- Select the correct wheel/tyre setting (e.g. road/track, summer/winter).
- Drive the vehicle to complete the procedure.
If the Warning Stays On
- Recheck every tyre against the correct front/rear figures — one below spec keeps the warning on.
- Pick the matching wheel/tyre profile after a seasonal or track-wheel swap.
- Drive a few minutes so the sensors report.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
Frequently Asked Questions
How do I reset the tyre pressure warning on a Porsche 718?
After a top-up just drive; after a wheel/tyre change, select the correct wheel/tyre profile on the PCM tyre-pressure page and drive to confirm.
Do the front and rear pressures differ?
Yes — the 718 runs wider rear tyres, so set each axle to its own figure.
Why won’t it clear?
Usually a tyre still below spec, or the wrong wheel/tyre profile selected after a wheel change.
Do I need a tool?
No for a normal reset; a tool is only needed if a sensor is replaced.
If the warning came on with other lights, decode the code on autodtcs.com.
