NOTICE
■Camera sensor
●Keep the windshield clean at all times.
LKA performance may deteriorate due to the presence of raindrops, con-
densation, ice or snow on the windshield.
● Do not attach a sticker or other items to the windshield near the camera
sensor.
● When adjusting the rear view mirror, make sure that it does not block the
camera lens.
● When it is cold, using the heater with air blowing to the feet may allow the
upper part of the windshield to fog up. This will have a negative effect on
the images. In such a case, use the windshield defogger to provide warm,
dry air to the windshield.
● Do not place anything on the dashboard.
The camera sensor may recognize the image reflected on the windshield
as lane markings by mistake.
● Do not scratch the camera lens, or let it get dirty.
● Do not change the installation position of the camera sensor or remove it.
The direction of the camera sensor is precisely adjusted.
● Do not subject the camera sensor to strong impact or force, and do not
disassemble the camera sensor.
Observe the following to ensure that the
LKA system functions correctly.

Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■ Operation of the air conditio ning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
● Engine speed and compressor operation controlled to restrict heating/
cooling 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 ( P. 204)
● Customize the air conditioning control of Eco drive mode. ( P. 590)
■ When outside air temperature is below 32 °F (0 °C)
The cooling and dehumidification function may not operate even when
is pressed.
■ Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic
mode.
■ Customization
Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.
(Customizable features P. 590)

If the interior lights remain on when the door is not fully closed and the inte-
rior light switch (door position on/off) is on, the lights will go off automatically
after 20 minutes.
■ Customization
Setting (e.g. The time elapsed before lights turn off) can be changed.
