Operation with the remote control
Important information
You can switch the auxiliary heating on/off and
set the operating duration using the remote con-
trol. You can use up to 4 remote control units on
the vehicle. These must be synchronized for the
receiver in your vehicle (
Ypage 109).
The remote control has a maximum range of
approximately 600 meters. This range is
reduced by:
Rsources of interference
Rsolid objects between the remote control and
the vehicle
Rthe remote control being in an unfavorable
position in relation to the vehicle
Rtransmitting from an enclosed space
