System Description

WARNING: This page is about a different car, the 2010 Lexus LS 460L and 2010 Lexus LS 460. However, it is still accessible from the selected car via links, so may be relevant.

DESCRIPTION
1. Safety Connect performs ACN (Automatic Collision Notification), manual emergency calling, stolen vehicle tracking and roadside assistance service, by audio and data communications between the vehicle and call center through the cellular phone network. As shown in the illustration, when a collision is detected, the system sends its location calculated based on GPS signals and the identification code of the DCM (telematics transceiver) to a call center. After the necessary information has been gathered, the call center will relay this information to emergency services.
