2007 Cadillac STS Owner's Manual - Page 457

{CAUTION: Inflating something too much can make it explode, and you or others could be injured. Be sure to read the inflator instructions, and inflate the tire to its recommended pressure. Do not exceed 36 psi (248 kPa). 7. Move the inflator kit switch to the I (on) position. The inflator kit will force sealant and air into the tire. Sealant may leak from the puncture hole until the vehicle is driven and the hole has sealed. 8. Make sure there is a proper connection between the tire valve stem and the sealant filling hose by looking at the air pressure gage. If there is not a pressure reading while the compressor is running, the connection between the inflator kit and the tire is bad. Check the attachment between the sealant filling hose and the tire valve stem. 457
