use a wet/dry shop vac or an extractor if you have one...or you if you have neither, you can go to any Home Depot or Lowe's and rent one or you can go to almost any Supermarket and rent a shampooer which usually has an attachment for upholstery .
After you vacuum it the best you can, leave the car out in the sun with the windows cracked just a little and it should be fine...
