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 “ACCESSORY” or “IGNITION ON” 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 ACCESSORY
mode. If the vehicle is left in ACCESSORY mode, 12-volt battery dis-
charge may occur.
■When starting the hybrid system
●Do not depress the accelerator pedal unnecessarily.
●If the hybrid system becomes difficult to start, have your vehicle checked
by your Toyota dealer immediately.
■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. Contact
your Toyota dealer immediately.

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 (0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. 128)
●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.

■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. 128)
●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.

2104-2. Driving procedures
■If the S indicator does not come on or the D indicator is displayed even
after shifting the shift lever to S
This may indicate a malfunction in the automatic transmission system. Have
the vehicle inspected by your Toyota dealer immediately.
(In this situation, the transmission will operate in the same manner as when
the shift lever is in D.)
WARNING
■When driving on slippery road surfaces
Do not accelerate or shift gears suddenly.
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 long period of time, the hybrid battery (traction
battery) will discharge, and this may result in the vehicle not being able to
start.

In the following conditions, the remaining lights will go off automatically after
20 minutes in order to prevent the 12-volt battery from being discharged:
●The headlights and/or tail lights are on.
●The power switch is in ACCESSORY mode or turned off.
This function will be canceled in any of the following situations:
●When the power switch is turned to ON mode.
●When the light switch is operated.
●When a door or the trunk is opened or closed.
■Welcome lighting
If the headlight switch is turned to and the surrounding area is dark,
unlocking the doors using the smart key system or wireless remote control
will turn the parking lights and tail lights on automatically.
■Customization
Some functions can be customized. (P. 526)
NOTICE
■To prevent 12-volt battery discharge

53004800470048005600570055004c004400510003004c0056[ high.
Each function is operational at the following speeds:
●Pre-collision warning:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180
km/h). (For detecting a pedestrian, vehicle speed is between approxi-
mately 7 and 50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 7 mph (10 km/h) or more.
●Pre-collision brake assist:
• Vehicle speed is between approximately 20 and 110 mph (30 and 180
km/h). (For detecting a pedestrian, vehicle speed is between approxi-
mately 20 and 50 mph [30 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 20 mph (30 km/h) or more.
●Pre-collision braking:
• Vehicle speed is between approximately 7 and 110 mph (10 and 180
km/h). (For detecting a pedestrian, vehicle speed is between approxi-
mately 7 and 50 mph [10 and 80 km/h].)
• The relative speed between your vehicle and the vehicle or pedestrian
ahead is approximately 7 mph (10 km/h) or more.
The system may not operate in the following situations:
●If a 12-volt battery terminal has been disconnected and reconnected and
then the vehicle has not been driven for a certain amount of time
●If the shift lever is in R
●If VSC is disabled (only the pre-collision warning function will be opera-
tional)
■Pedestrian detection function
■Cancelation of the pre-collision braking
If either of the following occur while the pre-collision braking function is oper-
ating, it will be canceled:
●The accelerator pedal is depressed strongly.
●The steering wheel is turned sharply or abruptly. The pre-collision system detects pedestri-
ans based on the size, profile, and motion
of a detected object. However, a pedes-
trian may not be detected depending on
the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. (P. 251)

2904-5. Using the driving support systems
■If “Clean dirt from lens” is displayed on the audio system screen
A rear camera lens may be dirty or covered with snow or ice. In such cases, if
it is removed from the rear camera lens, the system should return to normal.
(It may be necessary to drive the vehicle for some time before the system
returns to normal.)
■If “RCD unavailable” is displayed on the audio system screen
●If this message is displayed after the 12-volt battery has been disconnected
and reconnected, fully turn the steering wheel to the left and then the right
on level ground.
●If this message is displayed only when the R shift position is selected, the
rear camera lens may be dirty. Clean the rear camera lens.
■Situations in which the system may not operate properly
●Some pedestrians, such as the following, may not be detected by the rear
camera detection function, preventing the function from operating properly:
• Pedestrians who are squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the detection area
• Pedestrians riding a bicycle, skateboard, or other light vehicle
• Pedestrians wearing unusual clothing, such as a costume
• Pedestrians whose body is partially hidden by a cart or other object
• Pedestrians which are obscured by darkness, such as at night
●In some situations, such as the following, pedestrians may not be detected
by the rear camera detection function, preventing the function from operat-
ing properly:
• When backing up in inclement weather (rain, snow, fog, etc.)
• When the rear camera is obscured (dirt, snow, ice, etc. are attached) or
scratched
• When a very bright light, such as the sun, or the headlights of another
vehicle, shines directly into the rear camera
• When backing up in a place where the surrounding brightness changes
suddenly, such as at the entrance or exit of a garage or underground
parking lot

2964-5. Using the driving support systems
■The intuitive parking assist can be operated when
●Front corner sensors:
• The power switch is in ON mode.
• The shift lever is in other than P.
• The vehicle speed is less than about 6 mph (10 km/h).
●Front center sensors:
• The power switch is in ON mode.
• The shift lever is in other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Rear corner and rear center sensors:
• The power switch is in ON mode.
• The shift lever is in R.
• The vehicle speed is less than about 6 mph (10 km/h).
■Intuitive parking assist display
When an object is detected while the Toyota parking assist monitor or pan-
oramic view monitor is in use, the warning indicator will appear in the upper
part of the screen even if the display setting has been set to off.
■Sensor detection information
●The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
●Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.
●Objects may not be detected if they are too close to the sensor.
●There will be a short delay between object detection and display. Even at
slow speeds, there is a possibility that the object will come within the sen-

●Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.
●It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.
■If a battery terminal has been disconnected and reconnected
The system needs to be initialized.
To initialize the system, drive the vehicle straight ahead for 5 seconds or more
at a speed of approximately 22 mph (35 km/h) or more.
■If “Parking Assist Unavailable Please Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an object may not be detected. If the sensor thaws out,
the system should return to normal.
