After you inflate your tyres to the correct PSI, you must perform a TPMS Calibration via the touchscreen or dashboard menu. If you don't, the warning light will stay on or will flash randomly. The manual states you should do this while the car is stationary.

The Honda Jazz is often described as "unbreakable," but its tyres are the only thing connecting that bulletproof chassis to the greasy, potholed roads of the United Kingdom. Whether you are navigating the incline of Hardknott Pass in Cumbria or parallel parking on a narrow street in Brighton, the correct tyre pressure (32 Front / 30 Rear, or 36 Rear for heavy loads) dictates your safety, your fuel bill, and your MOT pass rate.

With fuel prices in the UK consistently hovering above £1.40 per litre (often much higher), the Honda Jazz’s fuel efficiency is its main selling point. However, a tyre under-inflated by just 10 PSI increases rolling resistance dramatically. For a 1.4-litre or 1.5-litre i-VTEC engine, this translates to a fuel economy drop of up to 10%.

One of the most common misconceptions is that all Honda Jazz models share the same tyre pressure. This is false. The pressure varies significantly based on the generation (MK1, MK2, MK3, or MK4), the wheel size (14-inch, 15-inch, or 16-inch), and the load condition.
