3-26 Seats and Restraints If a person of adult size is sitting in the front outboard passenger seat, but the off indicator is lit, it could be because that person is not sitting properly in the seat. Use the following steps to allow the system to detect that person and enable the front outboard passenger frontal airbag and knee airbag: 1. Turn the vehicle off. 2. Remove any additional material from the seat, such as blankets, cushions, seat covers, seat heaters, seat massagers, a laptop, or other electronic devices. 3. Place the seatback in the fully upright position. 4. Have the person sit upright in the seat, centered on the seat cushion, with legs comfortably extended. 5. Restart the vehicle and have the person remain in this position for two to three minutes after the on indicator is lit. 6. Restart the vehicle. The passenger sensing system may or may not turn off the airbags for a child in a child restraint depending upon the child's seating posture and body build. It is better to secure a child restraint in a rear seat. Additional Factors Affecting System Operation Safety belts help keep the passenger in position on the seat during vehicle maneuvers and braking, which helps the passenger sensing system maintain the passenger airbag status. See "Safety Belts" and "Child Restraints" in the Index for additional information about the importance of proper restraint use. A thick layer of additional material, such as a blanket or cushion, or aftermarket equipment such as seat covers, seat heaters, and seat massagers can affect how well the passenger sensing system operates. We recommend that you not use seat covers or other aftermarket equipment except when approved by GM for your specific vehicle. See Adding Equipment to the Airbag-Equipped Vehicle on page 3‑28 for more information about modifications that can affect how the system operates.
