INFORMATION
Bulletin No.: 12-09-41-002
Date: December 04, 2012
Subject: Passenger Presence System (PPS) May Command Seat Belt Reminder Chime and Passenger Airbag Indicator On When Electronic Devices
or Conductive Objects are Placed on Front Passenger Seat
Models:
2012-2013 Buick Verano

Some customers may comment about 5 slow chimes, with no obvious reason. If the customer would check the PPS display, they would notice the
passenger seat belt indicator is illuminated. Dealers should be aware that when certain conductive objects are placed on the front passenger seat, the
front passenger airbag indicator may illuminate. The seat belt reminder light/chime may also be activated. Examples of objects that could enable the
airbag include:
- Computers, Electronic Tablets
- Charging and Audio Cables
- Cell Phones
- Tech 2(R)
- Large Container of Liquid
- Groceries
An electronic device does not necessarily need to be turned on to cause this condition.
Because this vehicle is equipped with low risk passenger airbags, the PPS system is designed to turn the airbag on for most front seat occupants and
turn the airbag off for small children in child seats. The system works by detecting the capacitance of the object on the seat, not the objects weight;
and certain conductive objects will enable the airbag. The passenger seat belt reminder system is active when the passenger airbag is on.
For additional information regarding the "capacitance monitoring" style of Passenger Presence (PPS) system for the vehicles listed in this bulletin:
- in the U.S., refer to GM Training video 10212.01D (January 2012 Emerging Issues) and course number 22048.42W (Safety Systems 1) and
22048.31T (Occupant Safety Systems Diagnostics) at gmtraining.com.
- in Canada, refer to GM Training video 52012.03V (TAC TALK for March 2012) and course number 22048.42W (Safety Systems 1) on LMS.
Please advise the customer to avoid placing the electronic device or conductive object in the front passenger seat in the future to eliminate unwanted
activation of the seatbelt reminder light/chime.
