Is there not a refrigerant label under the bonnet somewhere? That should state the weight of gas to charge the system with. For a small A/C system like what's in the Starlet I would have thought somewhere in the region of 450g-550g would be about right, although overcharging the system is very bad so if you decide to guess the amount then I wouldn't charge it with any more than 440g.
First thing you need to do though is check the pressure in the system and then recover any refrigerant that it's holding. If no or very little refrigerant is recovered, evacuate the system for approx 20 minutes and hold the vacuum for a further 5, if the vacuum drops then you've got a leak somewhere. Depending on the severity and age of the leak, the drier may have become contaminated from moisture in the atmosphere and will most likely need replacing. If the system holds vacuum then you might want to think about injecting some compressor oil before fully recharging the system.

The refrigerant weights are usually in normal simpleton digits.
Have you no yellow label with R134a on it?
