Your not really SOL too much... go to www.helminc.com and buy yourself another owner's manual. Such things will help sell the car later too, especially if you keep up the maintenance specified in the manual.
I don't know of too many dumb people going out and buying premixed antifreeze so your question begs my question... why do you think you need antifreeze? While it is a good idea to flush the old coolant and replace it every two years, is the car overheating or something? Maybe someone just told you the coolant level was low and you want to fix it...
If that's the case, take a look at this picture:

It's a picture of your radiator and it's associated hoses. Note item #4 is a hose leading to tank #1 from the radiator cap. Item #1 is the reserve tank where the radiator puts and takes coolant from. With the coolant system properly filled, this reserve tanks gets excess coolant as the engine heats up and the coolant expands. When things cool down and the liquid contracts coolant is drawn from this reserve tank. Open the cap on top of the reserve tank and pull out the dipstick to check the coolant level. It should be somewhere within all the marks on the stick. If there is nothing on the stick, you will need to verify if the tank is SOME coolant or else you will have to suspect air got into the radiator when the engine cooled. Hondas do not like air in their coolant systems.
If the tank is dry, the process of filling the coolant system is a bit more complex but is still considered very easy. You will need a small wrench, 10mm or 12mm if I remember right. Here's what you do...

You should do this with the system cold and NOT RUNNING! Find the upper radiator hose and follow it back to the engine. It attaches to item #6, the thermostat cover. On top of the thermostat cover is a bolt (item #15). This is the vent plug to get all the air out of your coolant system.
Take the radiator cap off and note the coolant level. Just because it is full doesn't mean all the air is out! Loosen the vent plug (item 15), the level in the radiator should go down and coolant should come out of the vent plug when the air is expelled. Keep adding coolant to the radiator as it goes down until coolant comes out of the vent, then tighten the vent bolt to seal the system. Top off the radiator, put the cap back on, and add coolant to the proper level on your reserve tank. You are done!
Unless the system is leaking or worse, burning coolant, you shouldn't have to worry about the system for another two years.
Good luck!
