EFU is a device for heating the intake air and fa-
cilitating engine starting at the ambient temperature of
minus 5 °С and below.

into the atmosphere. Furthermore, it results in lower wear
rates of starter and storage batteries as well as the re-
duced engine starting time.

trolled be the ECU.
To activate EFU, switch on the instruments by
rotating the instruments-and-starter switch key to the ON
position (position of motion).
