Cooling water level diagram
Caution! Overpressure cooling system. Use cap with marking "100" only.
Open cap only when cooling water temperature is below 90 deg Centigrade.
Release pressure on notch 1. Close cap to limit stop.
Therefore, these labels should be on or close to the expansion tank.
2 is the tire pressure label.
On my car, it is on the underside of the trunk lid. With open trunk it is in the quadrant that is closest to the trunk lock.
4 and 5 are for the softtop.
4: Important: Do not fold a damp softtop. If a softtop is folded for extended periods, open it intermittently and airate well.- See owners manual

These stickers are usually in the softtop compartment, on the inner sidewall on the driver side.
