Operating requirements
▷ The vehicle is in rest or standby state and not
in drive-ready state.
▷ The battery must be sufficiently charged.
When activated, the independent ventilation/
auxiliary heating uses power from the vehicle
battery. As a result, the maximum operating
time is restricted to protect the battery. After
the engine is started or after driving a short
distance, the system will be available again.
▷ Auxiliary heating: sufficient fuel in the tank.
If the fuel level is low and the vehicle is
parked on a slant, the function of the auxiliary
heating may be limited.
▷ Ensure that the date and time are set cor‐
rectly in the vehicle.
▷ Open the vents to allow the air to enter the
passenger compartment.
