EV drive mode (RX450h)
■ 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.
In EV drive mode, the electric motor (traction motor), powered by the
hybrid battery (traction battery), is used to drive the vehicle.
This mode allows you to drive in residential areas early in the morning and
late at night, or in indoor parking lots etc. without concern for noises and
exhaust gas emissions.
However, when the Vehicle Proximity Notification System is active, the
vehicle may produce sound.
Turns EV drive mode on/off
When EV drive mode is turned
on, the EV drive mode indicator
will come on. Pressing the
switch when in EV drive mode
will return the vehicle to normal
driving (using the gasoline
engine and electric motor [trac-
tion motor]).
