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 [traction motor]).
■Situations in which EV drive mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situations. If it
cannot be turned on, a buzzer will sound and a message will be shown on the
multi-information display.
●The temperature of the hybrid system is high.
The vehicle has been left in the sun, driven on a hill, driven at high speeds,
etc.
●The temperature of the hybrid system is low.
The vehicle has been left in temperatures lower than about 32
F (0C) for a
long period of time etc.
●The gasoline engine is warming up.
●The hybrid battery (traction battery) is low.
The remaining battery level indicated in the energy monitor display is low.
(P. 142)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
●The windshield defogger is in use.
EV drive mode
In EV drive mode, electric power is supplied by the hybrid bat-
tery (traction battery), and only the electric motor (traction
motor) 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 gas emissions.
However, when the Acoustic Vehicle Alerting System is active,
the vehicle may produce sound.

2144-2. 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 illumi-
nated, 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 drive mode indicator will flash and go off.
●The hybrid battery (traction battery) becomes low.
The remaining battery level indicated in the energy monitor on the multi-
information display is low. (P. 142)
●Vehicle speed is high.
●The accelerator pedal is depressed firmly or the vehicle is on a hill etc.

EV drive mode’s possible driving distance ranges from a few hundred meters
to approximately 0.9 miles (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 normal driving (using the gasoline engine and electric motor [traction
motor]). Driving in EV drive mode more than necessary may lower fuel econ-
omy.
■If “EV Mode Unavailable” is shown on the multi-information display
The EV drive mode is not available. The reason the EV drive mode is not
available (the vehicle is idling, battery charge is low, vehicle 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 accelerator pedal is
depressed too much) may be displayed. Drive the vehicle for a while before
attempting to turn on the EV drive mode again.

Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■To prevent an accident when releasing the shift lock
Before pressing the shift lock override button, make sure to set the parking
brake and depress the brake pedal.
If the accelerator pedal is accidentally depressed instead of the brake pedal
when the shift lock override button is pressed and the shift lever is shifted
out of P, the vehicle may suddenly start, possibly leading to an accident
resulting in death or serious injury.
NOTICE
■Hybrid battery (traction battery) charge precaution
If the shift lever is in N, the hybrid battery (traction battery) will not be
charged even when the engine is running. Therefore, if the vehicle is left
with the shift lever in N for a certain amount of time, the hybrid battery (trac-
tion battery) will discharge, and this may result in the vehicle not being able
to start.
