If the tyre-pressure warning has come on in your Infiniti Q30 (H15, 2015–2019) after you’ve adjusted the pressures or changed a wheel, you reset it from the dashboard Service menu and a short drive. It’s a normal request from the car, not a fault, and it clears once the system has read the corrected pressures. Here’s how.
How the System Works on the Q30
The Q30 uses a direct system with a pressure sensor in each wheel, and you kick off the reset from the driver’s instrument-cluster Service menu. Unlike a car that simply relearns unprompted, the Q30 wants you to open the tyre-pressure item and confirm, so it knows to take the current pressures as the new baseline. A short drive lets the sensors report in, the display shows the live pressures, and the warning clears once it accepts them.
Getting Ready
- Check pressures cold — before driving, or after a few hours parked.
- Inflate to the figures on the driver’s door-pillar label, which may differ front to rear.
- Set all four tyres before starting the menu reset.
- Have the ignition on and the car stationary so you can reach the Service menu.
When to Reset
- After checking or adjusting the tyre pressures.
- After changing or rotating wheels/tyres.
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.
If the Warning Stays On
- Recheck every tyre — one below spec keeps the warning on even if the others are correct.
- Complete the short drive so the system can read the corrected pressures at road speed.
- Cold weather can pull pressures below the threshold overnight; top up and re-run the menu reset.
- After a wheel swap or rotation, re-run the reset so the sensors are re-read in their new positions.
- Space-saver or non-sensored spare fitted? That corner can’t report, so the warning may hold until the proper wheel is back on.
- Still showing with correct pressures? A sensor may have a flat battery — look up the code on autodtcs.com.
What Happens Next
Once you confirm and the ‘Tyre pressure monitoring restarted’ message appears, the warning clears and the display shows the live pressures for each wheel. The system then watches quietly for the rest of the trip. You shouldn’t see the warning again unless a tyre genuinely drops or you change a wheel.
Frequently Asked Questions
How do I reset the tyre pressure light on an Infiniti Q30?
Set the pressures cold to the door-pillar figures, switch the ignition on, open the Service menu and choose Tyre pressure, then drive about 5 minutes and confirm. The ‘Tyre pressure monitoring restarted’ message tells you the new pressures are stored.
Why won’t the warning clear?
Usually a tyre still below spec, or the learn drive wasn’t completed. Cold weather, a space-saver spare, or a recently changed wheel can also keep it lit. Re-check every corner cold, set to the door-pillar figure, then re-run the Service-menu reset and drive.
Do I need a tool?
No for a normal reset; a tool is only needed if a pressure sensor is replaced. A new sensor has to be matched to the car before the system will read it, but the everyday reset is just the menu step and a short drive.
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 inflate only one corner and restart monitoring, the others are still taken as the reference — so check every tyre before you confirm.
Does cold weather set off the warning?
Yes — pressures fall as temperatures drop, so a cold snap can trip the light even if you set them correctly recently. Check them again cold, inflate to the door-pillar figure, and re-run the reset; setting toward the top of the range helps through winter.
How far do I need to drive?
About five minutes is usually enough for the sensors to report and the display to update, but give it a little longer if the light lingers. Steady driving rather than low-speed stop-start traffic helps the system confirm all four pressures.
