the 2.4 is measured in bar. A bar is 14.5 psi, so its basically telling you that your tyre pressures should be 35psi. If the Granvia is anything like the Estima family for tyre wear, you'll likely be better at using around 38-40psi.
No no no, Silly Gary a bar is somewhere stocked with beers and spirits
I agree though ignore the pressure on the door and the tyres should last a good while longer, not sure the Jap pressure is so far from the pressure that spreads tyre wear and tear evenly.
Bear in mind we're talking about the Estima so keep an eye out for uneven wear and be prepared to adjust the pressure accordingly
