occur.
EV drive mode
In EV drive mode, electric power is
supplied by the hybrid battery
(traction battery), and only the
electric motor (traction motor) is
used to drive the vehicle.
This mode allows you to drive in res-
idential areas early in the morning
and late at night, or in indoor park-
ing lots, etc., without concern for
noises and gas emissions.
