Safety Warning

Activating The Parking Assistance System (Pas) (2008-)
The function for parking assistance system (PAS) is activated using 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 parking assistance system (PAS), the Climate control module (CCM) transmits a signal, about the selected status via the CAN network to the Parking Assistance Module (PAM) (4/86).
Parking Assistance Module (PAM) then sends a signal to the Climate control module (CCM) stating whether the parking assistance function is on or off.
The Climate control module (CCM) uses the information to light and extinguish the LED on the switch.
