The "residual heat" function is only available in Canada.
It is possible to make use of the residual heat of the engine to continue heating the stationary vehicle for up to 30 minutes after the engine has been switched off. The heating time depends on the coolant temperature and on the interior temperature that has been set.

If you activate the residual heat function at high temperatures, only the ventilation will be activated.
