In a word.... no.
The cooling system is sealed (pressurized). So you really shouldn't be smelling any coolant. If you are, and haven't spilled/added any recently, you might have a leak someplace.
Couple things to check...
- level of the coolant - has it dropped?
- noticed any puddles in front of the right rear wheel?
- any moisture/condensation on inside of trunk lid above coolant cap?
- feel the carpet in trunk. is it wet?
- what are the last 2 digits on your coolant cap (.01 is revised version but they are on .02) Could be a bad cap
- any crusty white residue on black filler plate below cap?
- remove the filler plate (take off oil filler cap too and pry up plate. There is a black cap w/ 8-10 bolts and a bent paperclip looking thing in the middle. Any white crusty residue around it?
Report back your findings and we can steer you in the right direction which probably includes a pressure test if you have the updated .01 or .02 cap
Good luck

Anyhow, you'll want to get the updated coolant cap ~ $20. Same p/n as existing but w/ .01 (or .02) on end. Still, I recommend you pull up the filler panel and check out the pressure relief valve/cap (black thing w/ lots of bolts and bent paperclip thing in middle). Also check your carpet in the trunk for moisture. I'd just go ahead and have a pressure test done on the system. If it checks out ok, then your issue was just the bad cap.
