CAUTION
■
Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the vehi-
cle, press and hold the “POWER” switch for more than 3 seconds, or press it
briefly 3 times or more in succession.
However, do not touch the “POWER” switch while driving except in an emer-
gency. Turning the hybrid system off while driving will not cause loss of
steering or braking control, but the power assist to these systems will \
be lost.
This will make it more difficult to steer and brake, so you should pull over
and stop the vehicle as soon as it is safe to do so.
NOTICE
■To prevent 12-volt battery discharge
●Do not leave the “POWER” switch in ACCESSORY or ON mode for long
periods of time without the hybrid system on.
● If is displayed on the multi-information display, the “POWER”
switch is not off. Exit the vehicle after turning the “POWER” switch off.
● Do not stop the hybrid system when the shift lever is in a position other
than P. If the hybrid system is stopped in another shift lever position, the
“POWER” switch will not be turned off but instead be turned to ACCES-
SORY mode. If the vehicle is left in ACCESSORY mode, 12-volt battery
discharge may occur.
■ When starting the hybrid system
Do not depress the accelerator pedal unnecessarily.
■ Symptoms indicating a malfunction with the “POWER” switch
If the “POWER” switch seems to be operating somewhat differently than
usual, such as the switch sticking slightly, there may be a malfunction. Con-
tact your Toyota dealer immediately.

2-1. Driving procedures
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 morn-
ing and late at night, or in indoor parking lots etc. without concern
for noises and gas emissions.
However, when the Vehicle Proximit y 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 indica-
tor 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]).

When driving
■
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.
■ 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 68
F (20C)
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. 39)
● Vehicle speed is about 25 mph (40 km/h) or more.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.

168 2-1. Driving procedures
■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” display is
low. ( P. 39)
● Vehicle speed becomes more than about 25 mph (40 km/h).
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
■ Possible driving distance when driving in EV drive mode
EV drive mode’s possible driving di stance ranges from a few hundred yards
(a few hundred meters) to approximately 1.3 miles (2 km). Driving is possible
at speeds of less than approximately 25 mph (40 km/h). However, depend-
ing 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 Toyota 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.
CAUTION
■Caution while driving
When driving in EV drive mode no engine noise is made. As such, pedestri-
ans, people riding bicycles or other people and vehicles in the surrounding
area may not be aware of the vehicle starting off or approaching them.
Therefore, take extra care while driving even if the Vehicle Proximity Notifi-
cation System is active.
