NOTICE
■To prevent 12-volt battery discharge
●Do not leave the power switch in ACCESSORY or ON mode for long peri-
ods of time without the hybrid system on.
● If the smart key system indicator light (green) is illuminated (vehicles with-
out multi-information display), or “POWER ON” is displayed on the multi-
information display (vehicles with multi-information display) the hybrid sys-
tem is not off. When exiting the vehicle, always check that the power
switch is off.
■ When starting the hybrid system
If the hybrid system becomes difficult to start, have your vehicle checked by

Driving
EV drive mode
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 dri ve mode cannot be turned on
It may not be possible to turn EV drive mode on in the following situati\
ons. 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. 102, 108)
● Vehicle speed is high.
● The accelerator pedal is depressed firmly or the vehicle is on a hill etc.
● The windshield defogger is in use.
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 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.

■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 cancelatio n of EV drive mode
When driving in EV drive mode, the gas oline 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. 102, 108)
● Vehicle speed is 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 0.6 mile (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 driv\
ing
conditions.)
■ Changing a driving mode when in EV drive mode
EV drive mode can be used in conjunction with Eco drive mode and power
mode.
However, EV drive mode may be automatically canceled when used in con-
junction with power mode.
■ 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.
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 bicy-
cles or other people and vehicles in the area may not be aware of the vehi-
cle starting off or approaching them, so take extra care while driving.
Therefore, take extra care while driving even if the vehicle proximity notifica-
tion system is active (vehicles with vehicle proximity notification system).

4-2. Driving procedures
■About engine braking
When shift position B is selected, releasing the accelerator pedal will apply
engine braking.
• When the vehicle is driven at high speeds, compared to ordinary gasoline-
fueled vehicles, the engine braking deceleration is felt less than that of
other vehicles.
• The vehicle can be accelerated even when shift position B is selected.
If the vehicle is driven continuously in the B position, fuel efficiency will
become low. Usually, select the D position.
■ Automatically P positi on selection function
When the shift position is in a position other than P, pressing the power switch
with the vehicle stopped completely will cause the shift position to change to
P automatically, and then the power switch will turn off.
■ If the shift position cannot be shifted from P
There is a possibility that the 12-volt battery is discharged. Check the 12-volt
battery in this situation. ( P. 541)
■ After recharging/reconnecting the 12-volt battery
P. 443
■ Customization
Settings (e.g. Reverse warning buzzer) can be changed.

NOTICE
■Hybrid battery (tract ion battery) charge
If the shift position is in N, the hybrid battery (traction battery) will not be
charged. To help prevent the battery from discharging, avoid leaving the N
position selected for an extended period of time.
■ Situations where shift control system malfunctions are possible
If any of the following situations occurs, shift control system malfunctions
are possible.
Immediately stop the vehicle in a safe place on level ground, apply the park-
ing brake, and then contact your Toyota dealer.
● Vehicles without multi-information display:
When the “P LOCK MALFUNCTION W H E N PA R K I N G, PA R K I N F L AT
PLACE AND APPLY PARKING BRAKE SECURELY” warning message
appears on the instrument cluster. ( P. 494)
● Vehicles without multi-information display:
When the parking lock system warning light is illuminated.
● Vehicles with multi-information display:
When the warning message indicating the shift control system appears on
the multi-information display. ( P. 508)
● When everything except the shift position indicator selection frame is illu-
minated.
● When the shift position indicator remains off.
■ Notes regarding shift lever and P position switch operation
Avoid repeatedly operating the shift lever and P position switch in quick suc-
cession.
The system protection function may activate and it will not be temporarily
possible to shift the shift position other than P. If this happens, please wait
for approximately 20 seconds before attempting to change the shift position
again.

Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged\
.
