■
Switching to EV drive mode when the gasoline engine is cold
If the hybrid system is started while the gasoline engine is cold, the gasoline engine will
start automatically after a short period of time in order to warm up. In this case, you will
become unable to switch to EV drive mode.
After the hybrid system has started and the “READY” indicator has illuminated, press the
EV drive mode switch before the gasoline engine starts to switch to EV drive mode.
■
Automatic cancelation of EV drive mode
When driving in EV drive mode, the gasoline engine may automatically restart in the fol-
lowing situations. When EV drive mode is canceled, a buzzer will sound and the EV drive
mode indicator will flash and go off.
●
The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy monitor” display is low.

■
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). However, depending on vehicle conditions, there are situations
when EV drive mode cannot be used.
(The distance that is possible depends on the 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 electric motor [traction motor]). Driving in EV
drive mode more than necessary 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.
