312000947 - E3030 REAR SCREEN AND REAR VIEW MIRROR DEMISTING - DESCRIPTION
DESCRIPTION
In the case of poor visibility it is possible to activate the demisting of the rear screen and the door mirrors (if present).The heating resistances for these components absorb a considerable amount of energy and are therefore controlled and deactivated after a certain period of operation; the defrosting is timed according to a logic managed by the Body Computer:- excluded during starting (INT/A);
- by the on signal coming from the dedicated button located in the panel near the heating/climate control system controls;
- on versions with AUTOMATIC AIR CONDITIONING, by the on signal for the MAX-DEF button in the control panel.
- at the key off (key OFF or extracted);
- via the disengagement signal from the dedicated button;
- with the battery voltage below 11.5 V;
- after the first 10 minutes of operation if the engine speed is below 960 rpm.
The deactivation of the MAX-DEF control only causes the switching off of the heated rear windscreen if the command to switch it on came from the MAX-DEF button; if, on the other hand, the command was given via the heated rear windscreen button, it remains on. |
On versions with a manually operated air conditioner and heater, the defrosting can only be activated using the dedicated button. |
