Automatic cancelation of EV drive mode
■
When driving in EV drive mode, the gasoline engine may automatically restart
in the following 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.
●
Vehicle speed is high.
●
The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
Possible driving distance when driving in EV drive mode
■
EV drive mode's possible driving distance ranges from a few hundred meters
to approximately 1.3 miles (2 km). 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 econ-
omy.
Vehicle Proximity Notification System sound
■
Even when EV drive mode is turned on, the Vehicle Proximity Notification
System may produce a sound. (P. 72)
WARNING
Caution while driving
■
When driving in EV drive mode no engine noise is made. As such, pedestri-
ans, people riding bicycles or other people and vehicles in the surrounding
area may not be aware of the vehicle starting off or approaching them even
if the Vehicle Proximity Notification System is active. Therefore, take extra
care while driving.
