After adjusting the tyre pressures or changing a wheel on your Mercedes-Benz CLA (C118, 2019–present), you store the new values as the reference through the MBUX menu. Here’s how to clear the tyre-pressure warning.
Set the Pressures First
Park on level ground and inflate all four tyres cold to the figure on the driver’s door-pillar label, then store the reference.
How to Reset the CLA TPMS
- Adjust the pressures, then switch the ignition on.
- On the MBUX touchscreen (or the cluster menu), open ‘Vehicle’.
- Go to ‘Tyre pressure’ and select ‘Restart’ / ‘Confirm tyre pressures’.
- Confirm — the system stores the new pressures and begins monitoring against them.
The warning then clears once the car has confirmed the readings while driving.
If the Light Stays On
- Re-check every tyre — one low corner keeps the warning on.
- Always re-store after inflating or a wheel change — the system needs the new baseline.
Frequently Asked Questions
How do I reset the tyre pressure light on a Mercedes CLA?
Set the pressures, then in MBUX go to Vehicle → Tyre pressure and choose Restart/Confirm.
Do I need a tool?
No — the CLA stores the reference from its own menu; a tool is only needed if a sensor was replaced.
Why does the light come on in cold weather?
Pressures drop as temperature falls. Top up to the label figure and re-store.
It came on after a wheel change — why?
The reference moved. Re-run the store so the new pressures become the baseline.
