For Vehicles Equipped with an Airbag
Do not place a portable device in the area over the airbag or in the airbag deployment
area. An airbag inflates with great force. If a handset is placed in the airbag
deployment area and the airbag inflates, the handset may be propelled at high speed
and cause serious injury to occupants of the vehicle.
