My apologies for the delay. So what was stated on your registration renewal card was whether you needed to be re-checked for SMOG and your renewal fees. These are good for 2 years so if you remember doing this last year you are good, if you didn't do this last year the fee is $25 at the test stations. Information on this can be found here
Important note on this is that newer vehicles are not required to be tested until the fourth model year. For your vehicle, this puts you right at the time to be tested unless you did it last year. Again, though its only 25 dollars for the SMOG test.
To renew you can actually do this online here UNLESS
your vehicle is a diesel, which I believe it may be. Because emissions testing for diesel vehicles is different, HERE
is the list of the testing stations for them with the fee each station charges, it is slightly different at each but around the same range of prices.
Unfortunately I cannot calculate the actual dollar amount of the renewal - you CAN however call the country clerk on monday
to find the information because you lost yours. Typically this is a function of vehicle age, mileage, taxable value etc on newer vehicles.
Your clerk is:
