Starting the parking heater via the timer
The left control lever controls the start timer for the parking heater. No other timer is required when setting the timer control. The control lever is directly connected to the steering wheel module (SWM) (3/130) which sends a signal via the CAN-net to the central electronic module (CEM), which in turn sends the signal on to the accessory electronic module (AEM) (4/78) when it is time to start the electric heater.
The start timer functions on either the electric or fuel-driven parking heater (not XC90). The accessory electronic module (AEM) is not involved when the fuel-driven parking heater is selected. The heater to be used is selected in the driver information module (DIM) (5/1).
It is also possible to combine this function with the remote start function.
