Just follow instructions, don't sniff it, touch it or lick it...or eat it,
or touch it, and stick your infected finger in your eye or other orifice,
such as picking your nose while freoning. or if you do touch it, don't touch
buttons with writing on them inside the car. they will have writing no
longer..not that I would know (grin)
Since you could possibly know what you are doing....
give it a try. a fast leak is quite obvious.tastes like peppermint, and you
will want to think fast after that point.

*****why not

Any car that new is not going to have "freon" in it.  They haven't put freon
in cars for a long time.  I think they use something called 134a now
(supposed to be less harmful to the ozone layer).  I've dealt with a lot of
leaks in my other car, and they are not easy to find or rectify without the
right equipment.  You can try adding some coolant (make sure it's the right
stuff), but as you do you will have to figure out where the leak is.  Most
pros have sniffers that tell them where the leaks are.  If you don't find
the leak you will be topping it off forever.  If you do find the leak you
will have to figure out how to fix it.  BTW, I had my other car converted
from Freon to 134a by a pro to the tune of $2500.  Works great and I don't
have to mess with it anymore.  FYI previous problems encountered with that
car were a leaky compressor, leaks in the condenser, a failed condenser fan,
and leaks in the hose fittings.  At that time I was able to fix everything
myself except the leaky condenser (had to go to a radiator shop).
