TEEN DRIVER
Teen Driver allows multiple keys to be registered for beginning
drivers. When active, the system automatically activates certain safety systems, allows setting of some features, and limits the use of others. An in-vehicle Report Card records vehicle data about driving behavior. When the vehicle is started with a registered key, a Driver Information Center message displays that Teen Driver is active.
To create a Personal Identification Number, register a key, change Teen Driver settings, or access the Report Card, go to Settings > Vehicle > Teen Driver.
