Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Activating Automatic Start/Stop Of Engine (Only On Vehicles With The Function Automatic Start/Stop Of Engine)
The function automatic start/stop of engine is activated with the switch (3/286) located in the tunnel console.
The ignition key must be in position II and the engine running for the climate control module (CCM) (3/112) to accept activation of this function.
When activating the function automatic start/stop of engine, Climate control module (CCM) sends a signal about chosen status of the function to Engine control module (ECM) (4/46) via the CAN-net.
Then, Engine control module (ECM) sends a signal to Climate control module (CCM) if the function automatic start/stop of engine is on or off.
The Climate control module (CCM) uses the information to light and extinguish the LED on the switch.
