Independent heater

An independent heater heats or ventilates the vehicle interior depending on the value set on the automatic air conditioner and the air temperature in the interior.

All functions of the independent heater can be called up by the remote control. The independent heater can be switched on immediately (instant heating) or program it so that it turns on automatically at the required time (software heating).

The switch on the centre console can be used to switch the independent heater on and off and reset the activated on time.



The independent heater only switches on when the coolant temperature is below 70°C.

There is a risk of fire and poisoning!

It is forbidden to turn on independent heating at filling stations and in closed rooms without an exhaust hood (for example, in garages).

Note: Under appropriate temperature and weather conditions, it may happen that the system first produces ventilation and then heating, for example. This ensures that the required temperature can be reached as quickly as possible.

To achieve the maximum range of the remote control, it is recommended to fully extend the antenna during transmission and hold the remote control vertically. Transmission continues as long as the display indicator flashes.

The maximum range of the remote control is 1000 m. In closed rooms or due to massive obstacles, the range may be limited.

The operating time of the independent heater set at the factory is 50 minutes. However, it can also be set individually. Any service station will provide information on this issue "Mercedes-Benz".

The remote control for the independent heater can be stored in the storage compartment, in front of the selector lever, in a holder.
