If this happens, use the following steps to allow the system to detect that person and enable the right front passenger frontal airbag and seat-mounted side impact airbag (if equipped): 1. Turn the vehicle off. 2. Remove any additional material from the seat, such as blankets, cushions, seat covers, seat heaters, or seat massagers. 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. If the shoulder portion of the belt is pulled out all the way, the child restraint locking feature will be engaged. This may unintentionally cause the passenger sensing system to turn the airbag(s) off for some adult size occupants. If this happens, let the belt go back all the way and start again. 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 Your Airbag-Equipped Vehicle on page 1-56 for more information about modifications that can affect how the system operates. 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. { CAUTION: Stowing of articles under the passenger seat or between the passenger seat cushion and seatback may interfere with the proper operation of the passenger sensing system. 1-55
