• shift the transmission to position R
• depress the accelerator pedal
• switch off the ECO start/stop function or switch to drive program S or M

• the system detects moisture on the windshield when the air-conditioning system is switched on.
• the temperature in the vehicle interior deviates from the set range.
• the charge level of the battery is too low.
