42. Note: The GLS 63 AMG offers "AMG Dynamic PRE-SAFE", which tightens belts 20% faster in high-G scenarios (e.g., rear-seat passengers during aggressive braking).

3. Rear Curtain Airbag Activation


43. Under "Airbag Systems", select "Curtain Airbags".
44. Enable "Rear Occupant Detection" (standard on GLS 450+ and above).
45. For models with optional rear-seat sensors, calibrate the system to deploy airbags based on:
46. Passenger weight (adjustable thresholds: Child, Adult, Heavy Cargo).
47. Seat position (e.g., disabling side airbags if rear seats are folded flat for cargo).

4. PRE-SAFE Brake Support Integration


48. Link PRE-SAFE to Active Brake Assist via "Collision Mitigation".
49. Set "Rear-Seat Load Compensation" to:
50. Active (adjusts braking force if rear cargo exceeds 300 kg).
51. Passive (standard braking but with extended warning times for rear passengers).

5. Validation and Test Mode


52. Use the "Test PRE-SAFE" function (available in service mode) to simulate a collision.
53. Observe:
54. Seatbelt tensioning (front and rear).
