When you open the driver's door, there should be a sticker or plaque on the forward facing side of the door pillar. (The B pillar, not the one nearer the windscreen.) It should give the tyre pressures.
They are probably 30 PSI rear, 32 PSI front.
However, some advocate using 34 PSI in front because of the the tendency for the Jazz to wear the edges of the front tyres with 16 inch wheels.
