Three dealers gave me 3 different answers- 1. Under spare in trunk. 2. Under back seat cushion 3.Rear side panel to the right of rear seat. Have only looked under spare and cannot find it. Also one dealer said "DON'T OPEN IT YOURSELF" because of extremely high pressure. Is there a trick to opening it should I ever locate it? Thanks.
