If the tyre-pressure warning has come on in your Infiniti Q70 (Y51, 2014–2019) after you’ve adjusted the pressures or changed a wheel, it just means the system needs to relearn the corrected values. The light is a prompt, not a fault — the Q70 monitors each tyre against a reference and flags any drop, so a top-up or a wheel swap leaves it comparing against the old figures until you reset and drive. You reset it from the dashboard menu and a short drive. Here’s how.
How It Works on the Q70
The Q70 uses a direct system — each wheel has its own pressure sensor that reports to the car, so the display can show the actual reading at every corner. Because the sensors sit inside the wheels, a wheel change or a seasonal swap means the car has to relearn the set that’s fitted, and that relearn only completes once you’ve started the reset and driven far enough for every sensor to report. This is why the procedure asks for a short drive rather than just a menu tap.
Getting Ready
- Check and set pressures cold — before you’ve driven, so heat build-up doesn’t inflate the reading.
- Use the figure on the driver’s door-pillar label, matching your load if two figures are listed.
- Set all four corners correctly before you start the reset, not just the one that was low.
- Park level with the parking brake on and the lever in P.
- Plan a short, safe drive at over 25 km/h to complete the relearn.
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’.
- Adjust all four tyres to the correct cold pressures, then switch the ignition on (do not start).
- Press the cluster menu button to ‘SETTINGS’, scroll to ‘TPMS RESET’ and confirm.
- Select ‘Start’, then 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 — compare all four with the label figure.
- Complete the drive. The relearn needs sustained road speed; a short crawl round the car park won’t finish it.
- Re-store after any wheel change. A seasonal or rotated set needs a fresh relearn before the light will clear.
- Check the spare if your car monitors it — a low or long-parked spare can hold the warning.
- Cold snap. Pressures fall as the temperature drops; top up to the label figure and reset.
- Slow puncture. If one corner keeps dropping after you reset, look for a nail or a weeping valve.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
What Happens Next
Once the relearn completes on your drive, the warning goes out and the display shows the corrected pressures at each corner. It should then stay off for the trip and afterwards, because the system now has a fresh reference for the fitted wheels. A light that comes back on a cold morning is usually just seasonal pressure loss — top up and reset. One that returns quickly, or with the pressures confirmed correct, points to a leak or a tired sensor rather than a failed reset.
Frequently Asked Questions
How do I reset the tyre pressure light on an Infiniti Q70?
Set all four tyres cold to the door-pillar figure, switch the ignition on without starting, then use the cluster menu to reach SETTINGS > TPMS RESET > Start, and drive above 25 km/h (15 mph). The relearn finishes as the sensors report and the warning then clears.
Why won’t the warning clear?
Usually a tyre still below spec, or the relearn drive wasn’t completed. Re-check all four against the label, then start the reset again and drive at a steady road speed long enough for every sensor to report.
Do I need a tool?
No for a normal reset — the menu reset plus a short drive handles it. A tool is only needed if a pressure sensor is replaced and has to be registered to the car.
Does adjusting one tyre need a full reset?
Set all four correctly first, then run the menu reset so the baseline is right. If you only correct the low corner and skip the reset, the car keeps comparing against the old reference and the light stays on.
Why does the light come on in cold weather?
Air pressure drops as the temperature falls, so on a cold morning the tyres can read low enough to trip the warning even with no leak. Set each corner back to the label figure while the tyres are cold and run the reset, and it clears.
How far do I need to drive to finish the relearn?
There’s no fixed distance, but the car needs a few minutes at over 25 km/h so every wheel sensor reports. A short trip on normal roads is usually enough; stop-start crawling may not build up sustained speed, so the relearn can take longer than expected.
If the warning came on with other lights, decode the code on autodtcs.com.
