Activating/deactivating the residual heat function
The residual heat function is only available in vehicles for Canada with automatic climate control.
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 temperature that has been set.

The indicator lamp in the
button
goes out.
Residual heat is deactivated
automatically:
