check the white sticker on the inside of the driver side door for correct tire pressure on all four sides.
for maintenance....did u check with toyota if they have anythng available.
since these auction vehicles dont usually come complete with service history...it is a good idea to all the basic work done at the same time.
oil change, all fluid change, brake maintenance, basic tuning including plugs, wires, dcap, rotor, pcv etc.
check with storm/sameer..he got a vitz recently and he can give u more info on how to get started.
