Looking from under the vehicle you should be able to see the drain plug, and a filler plug above that. The filler plug you can see from above the car, underneath the air filter box. Should be a 24mm hex bolt for both. You would remove the filler plug and use your finger to check the level, if it reaches your finger then the level is good. Conversely you could drain it and inspect the fluid better and replace it. The system takes 2 quarts. See below:
DRAIN MANUAL TRANSAXLE OIL
Remove the manual transmission filler plug and the gasket.
Remove the drain plug sub-assembly and gasket, and then drain the manual transaxle oil.
Install a new gasket and the drain plug sub-assembly.
Torque : 39 Nm (400 kgf-cm, 29 ft-lbf)
The fluid spec is described as "Toyota Genuine Manual Transmission Gear Oil LV", "API GL-4 and SAE 75W" or "API GL-4 and SAE 75W-90"
Hope this helps,
