How will removing the front passenger seat affect the driver airbag?

Yes the drivers side airbad will deploy aswell as the seatbelt.

Thank you Robert. I took the front passenger seat out of my 2008 Yaris Hatchback. I did not disconnect the negative battery terminal before doing this. The following indicator lights are on #1 SRS warning light is on, #2 Front passenger seat belt reminder light is flashing and #4 Passenger AIRBAG OFF indicator light is on. Description of these lights is on p. 89 of the Owner's manual that talks about Front Passenger Occupant Classification System.I only have a simple front airbag, no side airbags. QUESTION: Is there any way to avoid having these lights on and still have the driver's airbag functional? Thanks, Bob
