If the tyre-pressure warning has come on in your Infiniti Q50 (V37, 2013–2023) after you’ve adjusted the pressures or changed a wheel, you reset it from the dashboard menu and a short drive. It is a normal calibration step rather than a fault, and on this Q50 it takes only a minute at the wheel plus a brief drive to complete. Here’s how.
How the System Works
The Q50 uses a direct TPMS: each wheel carries its own sensor that transmits the actual pressure to the car, which is why the dash can flag a genuinely low tyre rather than just a difference between wheels. When you correct the pressures the sensors keep reporting the new figures, but the system needs to be told to take those as the reference — that is what the menu reset does. Confirm it, then drive so the car can read the corrected pressures at road speed and settle the warning.
First, a Few Checks
- Set the tyres cold for an accurate baseline — before driving, or well after the car has stood.
- Use the pressures on the driver’s door-pillar placard, matching the load if a laden figure is given.
- Do all four corners before the reset so the sensors report the right figures.
- Have the car stationary with the parking brake on for the menu steps.
- Know your menu controls — you’ll navigate the driver-display / vehicle settings to reach the TPMS option.
When to Reset
- After checking or adjusting the tyre pressures.
- After changing or rotating wheels/tyres.
Resetting the System
- Park level, apply the parking brake, and put the gear lever in ‘P’ (auto) or neutral (manual).
- Adjust all four tyres to the correct cold pressures, then switch the ignition on (do not start).
- Open the menu and select ‘Meter Settings’ > ‘TPMS Setting’ > ‘Tyre pressure reset’, then ‘OK’.
- Drive the vehicle at over 25 km/h (15 mph) to complete the relearn.
If the Warning Stays On
- Recheck every tyre — one below spec keeps the warning on.
- Complete the drive so the system can read the corrected pressures.
- Check the spare if a full-size wheel has been rotated in — it may be under-inflated.
- Cold morning? A temperature drop can lower every tyre; top up cold and reset again.
- Slow puncture — if one corner keeps falling, look for a nail or leaking valve rather than repeatedly resetting.
- After a sensor replacement, the new unit may need registering before the warning will clear.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
Once It’s Done
Once you confirm the reset and complete the short drive, the warning goes out and the system holds the corrected pressures as its reference for normal running. It should only light again if a tyre genuinely drops below spec. Because these are battery-powered in-wheel sensors, expect a normal service life of several years; if the warning starts behaving oddly on an older car, an ageing sensor battery is a common cause.
Frequently Asked Questions
How do I reset the tyre pressure light on an Infiniti Q50?
Set all four tyres to the correct cold pressures, switch the ignition on without starting, then in the menu select Meter Settings > TPMS Setting > Tyre pressure reset > OK. Drive above 25 km/h (15 mph) to finish the relearn and the warning clears.
Why won’t the warning clear?
Usually a tyre is still below spec, or the relearn drive wasn’t completed at road speed. Re-check every corner cold, confirm the reset in the menu, and drive steadily for a few minutes. If it persists with correct pressures, a sensor with a weak battery is the next thing to suspect.
Do I need a tool?
No for a normal reset — the menu step and a short drive are all it takes. A TPMS tool is only needed if a pressure sensor is replaced, because the new sensor may have to be registered to the car before the system will read it and clear the light.
Does adjusting one tyre need a full reset?
Set all four correctly first, then run the menu reset so the whole baseline is right. Adjusting a single tyre and resetting is fine, but only if the other three are already at their placard figures — otherwise you lock in a partly wrong reference.
The light came on in cold weather — should I worry?
Not on its own. Cold air lowers pressure, so an overnight temperature drop can trip a direct system even with healthy tyres. Inflate each tyre back to the door-pillar figure while cold, run the reset, and the warning should stay off unless a tyre is actually leaking.
Can I use the reset after fitting winter wheels?
Yes, provided those wheels have working sensors fitted and set to the correct pressures. Set them cold, run the menu reset, and drive to relearn. If a swapped-in wheel has no sensor or a dead one, the system won’t read it and the warning will stay on until that sensor is sorted.
If the warning came on with other lights, decode the code on autodtcs.com.
