If the tyre-pressure warning has come on in your Infiniti QX30 (H15, 2016–2019) after you’ve adjusted the pressures or changed a wheel, you reset it from the dashboard Service menu and a short drive. Here’s how.
The amber horseshoe symbol with the exclamation mark is the tyre-pressure monitoring (TPMS) warning. On the QX30 it lights when the system sees a pressure that has drifted below the stored baseline — most often simply because the air has cooled, you’ve topped a tyre up, or you’ve swapped a wheel. It is a notification, not a fault in the car. Once the pressures are correct and the system has re-read them, it goes out. A steady lamp means a low or changed pressure; a lamp that flashes for a minute or so at start-up and then stays on usually points to a sensor fault rather than a pressure problem.
How TPMS works on the QX30
The QX30 uses a direct system: a small battery-powered sensor sits inside each wheel and reports the actual pressure to the car, which is why live values can be shown on the display. Because the readings are real measurements rather than an estimate, the system needs the corrected pressures stored as its new reference after any change. That is what the Service-menu reset and short drive do — they tell the car “these are the correct pressures now.”
Before You Start
- Check pressures cold — before driving, or at least three hours after the car was last used. Warm tyres read high and will store the wrong baseline.
- Set all four to the figure on the driver’s door-pillar placard for your load, not a number from memory.
- Don’t forget the tyre you just topped up or the wheel you fitted — the whole set must be right.
- Have the ignition on and the car stationary for the menu steps; you’ll finish the reset on a short drive.
Resetting the System
- Set all four tyres to the correct cold pressures, then turn the ignition on.
- Open the ‘Service’ menu and select ‘Tyre pressure’.
- Drive the vehicle for about 5 minutes — the new pressures appear on the display.
- Confirm; ‘Tyre pressure monitoring restarted’ appears and the pressures are stored.
Frequently Asked Questions
How do I reset the tyre pressure light on an Infiniti QX30?
Set the pressures, ignition on, Service menu > Tyre pressure, drive 5 minutes, then confirm.
If the Warning Won’t Clear
- Recheck every corner with a gauge you trust. A single tyre a few psi low will keep the light on even if the others are perfect.
- Complete the short drive. The system needs to be moving to re-read all four sensors and store the new baseline.
- Measured cold? If you set them warm they’ll be under spec once cooled — re-check first thing in the morning and correct.
- Fitted a space-saver or spare? A wheel without a sensor, or a spare set to a different pressure, will show as low or as a fault until the road wheel is back on.
- Cold snap overnight? Pressure falls roughly 1–2 psi for every 10°C drop, so a frosty morning can trip the light on its own — top up to spec.
- Just swapped or rotated wheels? Re-run the Service-menu reset so the correct positions and pressures are stored.
- Still on with everything correct? A sensor with a flat internal battery can’t report — that needs a workshop check rather than a reset.
What to Expect After
Once the pressures are right and the drive is done, the warning goes out and stays off for the trip; the display shows the live pressures. If a tyre is losing air through a slow puncture the lamp will return as the pressure falls again — that’s the system doing its job, so have the tyre checked rather than just topping it up repeatedly.
Why won’t the warning clear?
Usually a tyre still below spec, or the learn drive wasn’t completed. Re-check all four cold, correct any that are low, then repeat the Service-menu reset and drive for five minutes so the car can read and store the new pressures.
Do I need a tool?
No for a normal reset; a tool is only needed if a pressure sensor is replaced.
Does adjusting one tyre need a full reset?
Set all four correctly first, then run the menu reset so the baseline is right.
Where do I find the correct pressures?
On the placard on the driver’s door pillar, which lists the recommended cold figures for normal and fully-laden loads. Use the loaded figure if you’re carrying passengers and luggage, and always set the tyres cold.
Can cold weather set the light off on its own?
Yes. Colder air lowers pressure, so a tyre that was correct in mild weather can read low on a frosty morning. Top the affected tyre back up to the placard figure while cold and the warning should clear on the next drive.
The light flashes then stays on — what does that mean?
A lamp that flashes for about a minute at start-up before going solid usually indicates a sensor or system fault rather than a low tyre. Check the pressures first, and if they’re all correct have the sensors read for a fault code.
