Turn the vent on and the fan on high. Then spray a moderate amount of Lysol into the HVAC air intake which is under the cowling in front of the windshield. The fan will suck it into the HVAC ducting. As soon as you're done spraying, turn the fan off and shut the vent off. By the time you get the fan turned off and the vent shut, the Lysol should be pretty well distributed through the ducting and after a day or two, it should be ok.
The carpeting and upholstery is probably full of smoke too, I'd spray a bottle or two of Febreeze odor eliminator onto them.
