You must type this out slowly during a race for this to work. It will show "CHEAT MODE" across the middle of the screen if it works. Pressing most of the F buttons (i.e. F6 for invincibility, F8 for freeze/unfreeze timer) will give you different effects, as well as the number buttons, alone and with any combination of Shift, Ctrl and Alt.
