Getting to Know Your G8

Your vehicle is equipped with a
Passenger Sensing System located in
the front passenger seat for the front
passenger airbag. There also is a front
passenger airbag status indicator locat-
ed on the inside rearview mirror.

Note: 

It is recommended that children not

be placed in the front passenger seat,
even with the Passenger Sensing System.
All children should be properly secured in

used. They may interfere with the airbag
sensors and will void the warranty.
