Possible driving distance when driving in
■
EV drive mode
EV drive mode's possible driving distance
ranges from a few hundred meters to
approximately 0.6 mile (1 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 nor-
mal driving (using the gasoline engine and
electric motor [traction motor]). Driving in
EV drive mode more than necessary may
lower fuel economy.
If "EV Mode Unavailable" is shown on
■
the multi-information display
The EV drive mode is not available. The rea-
son the EV drive mode is not available (the
vehicle is idling, battery charge is low, vehi-
cle speed is higher than the EV drive mode
operating speed range or accelerator pedal
is depressed too much) may be displayed.
Use the EV drive mode when it becomes
available.
If "EV Mode Deactivated" is shown on
■
the multi-information display
The EV drive mode has been automatically
canceled. The reason the EV drive mode is
not available (the battery charge is low,
vehicle speed is higher than the EV drive
mode operating speed range or accelera-
tor pedal is depressed too much) may be
displayed. Drive the vehicle for a while
before attempting to turn on the EV drive
mode again.
