NOTICE
■Hybrid battery (traction battery) air intake vent
● Do not place objects that will block the air intake vent. When the air intake
vent is blocked, the battery operations will be restricted and cause a
decline in fuel consumption.
● Clean the air intake vent regularly to prevent the hybrid battery (traction
battery) from overheating.
● Do not get water or foreign materials in the air intake vent as this may
cause a short circuit and damage the hybrid battery (traction battery).
● Do not carry large amounts of water such as water cooler bottles in the
vehicle. If water spills onto the hybrid battery (traction battery), the battery
may be damaged. Have the vehicle inspected by your Toyota dealer.
● There is a filter installed to the air intake vent. When the filter remains
noticeably dirty even after cleaning the air intake vent, filter cleaning or
replacement is recommended. For information regarding filter cleaning or
replacement, contact your Toyota dealer.
● If “MAINTENANCE REQUIRED FOR TRACTION BATTERY COOLING
PARTS SEE OWNER’S MANUAL” is shown on the multi-information dis-
play, the air intake vent and filter may be clogged. Refer to P. 406 for infor-
mation on how to clean the air intake vent.

NOTICE
■To prevent damage to the engine and its components
This vehicle is not installed with an engine coolant temperature gauge.
Instead, is shown on the multi-information display. The engine may
be overheating if is shown on the multi-information display. In this
case, immediately stop the vehicle in a safe place. ( →P. 531)

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle is parked in
a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this may cause
one side of the vehicle to brake differently than the other side. Also, the
parking brake may not securely hold the vehicle.
● If the electronically controlled brake system does not operate, do not fol-
low other vehicles closely and avoid hills or sharp turns that require brak-
ing.
In this case, braking is still possible, but the brake pedal should be
depressed more firmly than usual. Also, the braking distance will increase.
Have your brakes fixed immediately.
● The brake system consists of 2 or more individual hydraulic systems; if
one of the systems fails, the other(s) will still operate. In this case, the
brake pedal should be depressed more firmly than usual and the braking
distance will increase. Have your brakes fixed immediately.
NOTICE
■When driving the vehicle
● Do not depress the accelerator and brake pedals at the same time during
driving, as this may restrain the hybrid system output.
● Do not use the accelerator pedal or depress the accelerator and brake
pedals at the same time to hold the vehicle on a hill.
■ When parking the vehicle
Always set the parking brake, and shift the shift lever to P. Failure to do so
may cause the vehicle to move or the vehicle may accelerate suddenly if
the accelerator pedal is accidentally depressed.

Notes for the entry function
→P. 142
■ If the hybrid system does not start
●The immobilizer system may not have been deactivated. ( →P. 86)
Contact your Toyota dealer.
■ Steering lock
After turning the power switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
power switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor o verheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the hybrid system is turned on and off repeatedly in a short period
of time. In this case, refrain from operating the hybrid system. After about 10
seconds, the steering lock motor will resume functioning. ● Check that the shift lever is securely set
in P. The hybrid system may not start if
the shift lever is not securely in the P
position. “SHIFT INTO P POSITION TO
START” will be displayed on the multi-
information display.
“STEERING LOCK ACTIVE” will be dis-
played on the multi-information display.
Check that the shift lever is set in P.
Press the power switch while turning the
steering wheel left and right.

*: To improve fuel efficiency and reduce noises, set the shift lever in the Dposition for normal driving.
Suitable for enhancing the fuel economy, because the torque corre-
sponding to the accelerator pedal depression amount can be gener-
ated more smoothly than it is in normal conditions and the operation
of the air conditioning system (heating/cooling) will be minimized.
Eco drive mode
When Eco drive mode is turned on,
the “ECO MODE” indicator will
come on.
Pressing the Eco drive mode
switch again turns Eco drive mode
off.
■ Operation of the air conditio ning system in Eco drive mode
Eco drive mode controls the heating/cooling operations and fan speed of the
air conditioning system to enhance fuel efficiency. ( →P. 378) To improve air
conditioning performance, adjust the temperature setting or fan speed, o\
r turn
off Eco drive mode.
■ When the accelerator pedal is depressed while the shift position is in N
A buzzer will sound to inform the driver that the shift position is in N.

To set the parking brake, fully
pull the parking brake lever
while depressing the brake
pedal.
To release the parking brake,
slightly raise the lever and
lower it completely while press-
ing the button.
■Parking the vehicle
→P. 170
■ Parking brake engaged warning buzzer
A buzzer will sound if the vehicle is driven at a speed of approximately 3 mph
(5 km/h) or more with the parking brake engaged. ( →P. 482, 494)

NOTICE
■Before driving
Fully release the parking brake.
Driving the vehicle with the parking brake set will lead to brake components
overheating, which may affect braking performance and increase brake
wear.

ECB operating sound
ECB operating sound may be heard in the following cases, but it does not
indicate that a malfunction has occurred.
●Operating sound heard from the engine compartment when the brake pedal
is operated.
● Motor sound of the brake system heard from the front part of the vehicle
when the driver’s door is opened.
● Operating sound heard from the engine compartment when one or two min-
utes passed after the stop of the hybrid system.
■ EPS operation sound
When the steering wheel is operated, a motor sound (whirring sound) may be
heard. This does not indicate a malfunction.
■ Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the hybrid system
off. The EPS system should return to normal within 10 minutes.
■ Electric power steering system warning light (warning buzzer)
→P. 486
■ Automatic reactivation of TRAC and VSC systems
After turning the TRAC and VSC systems off, the systems will be automati-
cally re-enabled in the following situations:
● When the power switch is turned to the “LOCK” position (vehicles without a
smart key system) or the power switch is turned off (vehicles with a smart
key system)
● If only the TRAC system is turned off, the TRAC will turn on when vehicle
speed increases
If both the TRAC and VSC systems are turned off, automatic re-enabling will
not occur when vehicle speed increases.

■Operation of the air conditio ning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
● Engine speed and compressor operation controlled to restrict heating/cool-
ing capacity
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode
■ Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is pressed.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
