Auto Stop/Start Warning Indicator
WARNING: This page is about a different car, the 2019 Jaguar XJ and 2018 Jaguar XJ. However, it is still accessible from the selected car via links, so may be relevant.
On vehicles with Stop/start system, an Auto stop/start warning indicator is located in the IC (Instrument Cluster). The warning indicator illuminates green when the engine stops during a stop/start cycle, then goes off when the engine restarts. The warning indicator illuminates amber when the stop/start system is disabled. The warning indicator is controlled by a HS CAN powertrain systems bus message from the ECM.
