When you park your vehicle and turn off your zūmo^® device, the tire pressure sensor enters a power-saving sleep mode after several minutes. The sensor does not transmit information to the zūmo device while in sleep mode. This can cause your zūmo device to report the sensor is disconnected.

The next time your vehicle moves, the sensor exits sleep mode and automatically reconnects to the zūmo device. It may take up to 30 seconds to reconnect.
