Teen Driver
WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
The teen driver feature puts the vehicle into a mode that can only be unlocked with a valid PIN. It allows various restrictive features for safer driving. Some of the features include Speed Limiter, Speed Warning, Register Key, Report Card, etc. For additional information refer to owners manual.
In the event that the four digit code is forgotten, it can be sent via Bluetooth to the currently paired phone or the scan tool under BCM can be used to reset the Teen Driver PIN.
