■ When the shift control system malfunctions
The power switch will not be able to be turned off. In such a case, the switch
can be turned off after applying the parking brake.
Have the vehicle inspected by your Toyota dealer immediately.
■ Meter display
When the power switch is turned off, each display will turn off as follows.
●The shift position indicator will turn off after approximately 2 seconds.
● EV driving ratio and average fuel consum ption after hybrid system started,
turn off after approximately 6 seconds.
● The odometer, clock, etc. will turn off after approximately 30 seconds.
(Each display will also turn off immediately if a door is locked before 30 sec-
onds has elapsed.)
WARNING
■ When starting the hybrid system
Always start the hybrid system while sitting in the driver’s seat. Do not
depress the accelerator pedal while starting the hybrid system under any
circumstances.
Doing so may cause an accident resulting in death or serious injury.
■ Stopping the hybrid system in an emergency
If you want to stop the hybrid system in an emergency while driving the
vehicle, press and hold the power switch for more than 2 seconds, or press
it briefly 3 times or more in succession. ( P. 471)
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, however, power assist to the steering will be
lost. This will make it more difficult to steer smoothly, so you should pull over
and stop the vehicle as soon as it is safe to do so.

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 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. 96, 103)
● 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 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. 96, 103)
● 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 driving
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 s pecial 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 drivi ng even if the vehicle proximity notifica-
tion system is active (vehicles with vehicle proximity notification system).

WARNING
■When driving on slippery road surfaces
Do not accelerate or shift the shift position suddenly.
Sudden changes in engine braking may cause the vehicle to spin or skid,
resulting in an accident.
■ For the shift lever
Do not remove the shift lever knob or use anything but a genuine Toyota
shift lever knob. Also, do not hang anything on the shift lever.
Doing so could prevent the shift lever from returning to position, causing
unexpected accidents to occur when the vehicle is in motion.
■ P position switch
Do not press the P position switch while the vehicle is moving.
If the P position switch is pressed when driving at very low speeds (for
example, directly before stopping the vehicle), the vehicle may stop sud-
denly when the shift position switches to P, which could lead to an accident.
NOTICE
■Hybrid battery (traction 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 a certain 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.
●When the warning message indicating the shift control system appears on
the multi-information display. ( P. 489)
● 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.

PCS (Pre-Collision System)
◆Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision with a vehicle or pedestrian is high, a warning operates to
urge the driver to take evasive action and the potential brake
pressure is increased to help the driver avoid the collision. If the
system determines that the possibility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.The pre-collision system can be disabled/enabled and the warning
timing can be changed. ( P. 209)
