Can as use distilled water as a temporary coolant?

I'm normally pretty good at checking my fluids every time I fill up on gas, but on my 2001 Civic, the coolant reservoir is located directly beside the radiator underneath the battery, which makes it difficult to check. Furthermore, the interior of the reservoir is dirty, so it's nigh impossible to get a read. I took my car to serviced at the dealer last week for an oil change and inspection. They assured me my coolant was fine. However, my car recently started overheating with the heater being intermittently hot then cold. I didn't notice any leaks, but it was hard to tell since there was overflow, plus I lost reservoir cap (presumably from overflow; there isn't any securing mechanism for it). I tried checking coolant levels on on a cold engine, I gave the radiator/reservoir a good shake and couldn't feel any fluid sploshing around so I'm guessing I'm well below the minimum level.

I'm fortunate enough to live in an area that never reaches freezing temperature (even at the coldest nights in dead middle of winter rarely reach or fall below 32*F/0*C.

With that said, can I use distilled water as a band-aid fix until I get a chance to take my car in again?
