■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 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
following situations. When EV drive mode is canceled, a buzzer will sound and the
EV indicator will flash 3 times and go off.
●The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the “Energy Monitor” screen or the multi-
information display is low. ( →P. 112)
●Vehicle speed becomes more than about 25 mph (40 km/h).
●The accelerator pedal is depressed firmly.
When it is possible to inform the driver of automatic cancelation in advance, a prior
notice screen will appear on the multi-information display.
■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 mile (2 km). Driving is possible at speeds of less than approxi-
mately 25 mph (40 km/h). However, depending on vehicle conditions, there are sit-
uations 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
Your Lexus 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.
