While that is one solution to the problem at hand, I don't think that is what he's looking for. Shutting down the car probably meaning shutting off the engine. SetVehicleParams or something? I believe that is the function you are looking for (Someone please correct me if that function is incorrect though). But simply search the Wiki for every function to easily find that certain function plus alot more useful ones...
