"Charging Stopped Due to Pulled Charging Connector"

Cause

Remedy

●

Charging connector is re-
moved while charging

●

After the hybrid battery
(traction battery) is fully
charged, the charging con-
nector is removed while the
hybrid battery (traction bat-
tery) is being recharged
again because electricity-
consuming functions

have

been used and the remaining
charge is now reduced.

If the charging connector is disconnected dur-
ing charging, charging will be suspended. To
continue charging, reconnect the charging
connector.

Charging connector is not se-
curely connected

Check the connection status of the charging
connector.

●

When connecting the charging connector,
make sure not to touch the latch release but-
ton. Insert the charging connector securely
until you hear a click. The charging connec-
tor may not be connected correctly if the
latch release button is pressed while insert-
ing.

●

After connecting the charging connector,
check that the latch release button is not
pressed and the charging indicator of the
charging port is turned on.

If charging cannot be carried out, even though
the proper procedures were followed, have the
vehicle inspected by your Lexus dealer.
