The effective range of the radio remote control when the battery is charged is up
to 600 m. Obstacles between the remote control and the vehicle, bad weather
conditions and a weakening battery can reduce the range significantly.
To switch the auxiliary heating (aux. heating) on or off, hold the remote control
