> In cars with manual transmission: when you
shift gears very slowly or shift to neutral.
> In cars with automatic transmission: when
you engage selector lever position N.
> In cars with Sport au tomatic transmission
with double clutch: when you engage
selector lever position N.
> When the ignition is switched off.
