Activating/deactivating the residual heat function

Mercedes-Benz G-Class / Mercedes-Benz G-Class Owners Manual / Climate control / Operating the climate control systems / Activating/deactivating the residual heat function

The "residual heat" function is only available in Canada.

It is possible to make use of the residual heat of the engine to continue heating the stationary vehicle for up to 30 minutes after the engine has been switched off. The heating time depends on the coolant temperature and on the interior temperature that has been set.

The blower will run at a low speed regardless of the airflow setting.

If you activate the residual heat function at high temperatures, only the ventilation will be activated.

Turn the SmartKey to position 0 in the ignition lock or remove it.

To activate: press the button.

To deactivate: press the button.


The indicator lamp in the goes button
goes out.

 Residual heat is deactivated automatically:
after approximately 30 minutes when the ignition is switched on if the battery voltage drops if the coolant temperature is too low
