high energy consumption
of electrical compo-
nents, such as the head-
lights. Switch the electrical
appliance OFF, and
restart charging by fol-
lowing the procedure on
P. 80.
If the message is still

charge.
In this event, turn the
“POWER” switch OFF
approximately 15 min-
utes after starting the
hybrid system, and
restart charging.
Charging has been

Charging has been
stopped because of a
problem with the charg-
ing cable. If the charging cable is

charging using a charg-
ing station (other than a
Toyota dealer), try charg-
ing with a genuine Toyota
