MessageDetailsCorrection procedure
Charging has been
stopped because of the
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
stopped because of

inserted correctly, and
restart charging by fol-
lowing the procedure on

procedure
Charging has been
stopped because of a
problem with the charg-
ing cable. If the charging cable is
not a genuine Toyota
product, or if you are
charging using a charg-
ing station (other than a
Toyota dealer), try charg-
ing with a genuine Toyota
charging cable.
If the message is still
displayed, contact your
Toyota dealer.
Charging has stopped
because of the continued
high temperature of the
hybrid battery (traction
battery) (in order to pro-
tect the battery). If the desired charge
level has not been
achieved, restart charg-
ing by following the pro-
cedure on P. 80 after the
hybrid battery (traction
