E-Pretensioner System Description - Control/Function
CMBS and E-Pretensioner Operation
Approaching a vehicle ahead:
When driving, the millimeter wave radar detects a vehicle ahead, and the system provides audible and visual warnings if it detects a risk of collision.
Closing on a vehicle ahead:
The system applies light braking, and increases seat belt tension slightly to provide a tactile warning to the driver. There is no tactile warning for the front passenger.
Collision unavoidable:
The system activates strong braking, and securely tightens both the driver's and front passenger's seat belts to help reduce injury caused by the impact.
