The additional heater control module can be programmed with certain data. The aim with this programming is set up the additional heater function according to the customer's requirement. The programmable data is the adaptation of the start temperature.

The start temperature is the highest outside temperature at which the additional heater can start. At outside temperatures above the programmed value the heater cannot start. This does not apply to the parking heater function.
