Lumbar Support Description and Operation: Notes
WARNING: This page is about a different car, the 2022 Cadillac CT5. However, it is still accessible from the selected car via links, so may be relevant.
The memory lumbar/bolster system uses air bladders to adjust various aspects of the seat configuration to meet an occupant's preference. It also allows these adjustments to be stored to a memory position along with the seat position data.
Some vehicles may also be equipped with dynamic mode control which gives the chassis subsystem the ability to request an automatic adjustment to the seat's bolster support depending on vehicle driving conditions.
The various seat adjustments and functionality which may be possible include:
- Lumbar support - forward and rearward
- Seat back side bolster
The components of the system include:
- LIN based seat switch
- Driver Seat Adjuster Memory Module
- Front Seat Bolster Memory Module - Driver
- Air bladders
