If the tyre-pressure light is on in your Mazda CX-5 Mk2 (KF, 2017–present) after adjusting pressures or changing wheels, it usually just needs a short drive to relearn. The CX-5 uses a direct TPMS — a sensor in each wheel — and the reset is automatic once the pressures are right. Seeing the light after cold weather, a top-up, or a seasonal wheel swap is normal behaviour, not a fault: the system simply flags that a corner is below the stored reference and clears itself once you correct it and drive.
How the CX-5’s TPMS Works
Each wheel has a pressure sensor that reports to the car, so a low corner shows on the display. There’s no button or menu to confirm — you correct the pressures and the system relearns as you drive.
Because the sensors read actual pressure rather than inferring it from wheel-speed data, the CX-5 knows the real figure at each corner and doesn’t need you to teach it a baseline. That also means a steady amber light almost always reflects a genuine pressure difference, so it’s worth trusting the warning and checking with a gauge rather than assuming a glitch.
Before You Start
- Check pressures cold — before driving, or after the car has stood for a few hours. Warm tyres read high and give a false setting.
- Find the correct figures on the label in the driver’s door opening; use the higher values if you’re carrying a full load.
- Set all four corners, and check the spare if it’s a monitored full-size wheel.
- Have a reliable gauge — forecourt airlines are often out by a few psi.
- Plan a short drive so the sensors can report the corrected pressures.
How to Reset the CX-5 Mk2 TPMS
- Set all four tyres to the correct pressure cold — the figures are on the label in the driver’s door opening.
- Drive the vehicle for about 5 minutes, keeping above roughly 25 km/h (15 mph).
- The system relearns the corrected pressures and the warning clears.
If the Warning Stays On
- Re-check every tyre, including the spare if it’s a monitored full-size wheel — one low corner keeps the light on.
- One tyre keeps dropping — look for a slow puncture or a leaking valve; the system is doing its job.
- You only did a short trip — give it a longer steady drive so every sensor transmits.
- It came on overnight in cold weather — pressures fall as temperature drops; top up to the door-label figure.
- After a wheel swap — confirm each new wheel actually has a working sensor fitted.
- A steady-flashing TPMS light points to a sensor fault and needs a tyre shop’s tool.
What to Expect After
Once the pressures are correct and you’ve driven a few minutes, the amber light goes out and stays off for the rest of the trip and beyond — there’s nothing to save or confirm on screen. If it returns after a few days, one tyre is losing air slowly and should be checked. Expect the light to reappear on the first cold morning of autumn; that’s the pressure drop, not a fault.
Frequently Asked Questions
Does the CX-5 TPMS need a tool to reset?
Not for a normal reset — set the pressures and drive. A tool is only needed if sensors were replaced or swapped.
How long until the light goes out?
Usually within about 5 minutes of driving above 25 km/h after correcting the pressures. If you only pulled onto the drive and back, the sensors may not have transmitted yet — a longer steady run finishes the relearn reliably.
Why did the light come on in the cold?
Pressure drops as temperature falls. Top up to the door-label figure and drive.
The light keeps flashing — low pressure?
A persistent flash usually means a sensor fault rather than low pressure — have the sensors checked.
Do I need to reset after rotating the tyres?
No special reset is needed for a straight rotation because each wheel keeps its own sensor. Just confirm all pressures match the door label afterwards and drive; the system continues to read each corner correctly.
Can I keep driving with the light on?
You can drive to somewhere safe to check pressures, but don’t ignore it. A low tyre wears unevenly, raises fuel use and can overheat at speed. Check and correct the pressures at the first opportunity, then let the light clear.
