4-2. Driving procedures

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 cancellation 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.
The remaining battery level indicated in the "Energy monitor" display is low.
(P. 118)

Vehicle speed becomes high.

The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
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 km (0.6 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
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.
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.
