■Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving distance ranges from a few hundred meters to approxi- mately 2 km (1.2 mile). Howe ver, depending on vehicle conditions, there are situations
when EV drive mode cannot be used.
(The distance that is possible depends on th e hybrid battery [traction battery] level and driving conditions.)
■Fuel economy
The hybrid system is designed to achieve the best possible fuel economy during normal driving (using the gasoline engine and electr ic motor [traction motor]). Driving in EV
drive mode more than necess ary may lower fuel economy.
WARNING
■Caution while driving
When driving in EV drive mode, pay special attention to the area around the vehicle.
Because there is no engine noise, pedestrians, people riding bicycles or other people
and vehicles in the area may not be aware of the vehicle starting off or approaching them, so take extra care while driving.
