The transmitter and the battery are housed in the housing of the remote control. The receiver is located in the interior of the vehicle.
When the battery is fully charged, the range of the remote control is a few hun-
dred metres. Obstacles between the remote control and the vehicle, bad weather
conditions and a weaker battery in the remote control can clearly reduce the range.
To switch the auxiliary heating (aux. heating) on or off, hold the remote control
vertical, with the aerial
A
pointing upwards. The antenna must not be covered
with the fingers or the palm of the hand during this process.
The auxiliary heating can only be switched on/off safely using the radio remote control, if the distance between the radio remote control and the vehicle is at
least 2 m.
