Any previously spawned vehicles will disappear. You can usually only spawn one vehicle at a time. Enabling some cheats will prevent the indicated achievement(s) from being earned. Note: Do not save the game after enabling a code to avoid unforeseen problems. Once a code has been entered correctly, a new 'Cheats' menu option will be available on your phone, below 'Options', where you can access the cheats without having to enter the phone number again.
Then, enter one of the following codes to activate the corresponding cheat function.
