Starting the heater remotely
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2007 Volvo V70, 2006 Volvo V70, 2005 Volvo V70, 2004 Volvo V70, and 2003 Volvo V70. However, it is still accessible from the selected car via links, so may be relevant.
Cars with an accessory electronic module (AEM) (4/78) can have a remote start function for the heater. This allows the heater to be started using a pager. A stop or start signal is transmitted from the accessory electronic module (AEM) to the central electronic module (CEM) (4/56) to start or stop the heater (4/7). This function is available for both fuel driven and electrical heaters.
