Hyundai Santa Fe: DC DC converter / Description and operation
Due to the considerably more frequent occurrence of starting operations, the
electrical load that occurs often leads to voltage dips in the vehicle network.In
order to stabilize the power supply for certain voltage-sensitive electrical
components, a DC/DC converter is used in conjunction with the ISG function.The
DC DC converter supplies the relay with a voltage that also remains constant
during the starting operation.
The DC/DC converter is fitted at the behind of the glove box.Via the test leads
for input voltage and the start relay , the electronics decide whether the power
is supplied to the output via the bypass or the DC/DC converter.In the bypass
mode, the on-board supply voltage is not fed across the DC/DC converter, rather
is transferred directly to the outputs. In the booster phase, the vehicle voltage
is adapted.

Other information:
Fan speed control
Turn the knob to the right to increase the fan speed and airflow. Turn the knob
to the left to decrease fan speed and airflow.
Setting the fan speed control knob to the “0” position turns off the fan.
NOTICE
Operating the fan speed when the ignition switch is in the ON position could
cause the battery to discharge...
