CAUTION
■Handling the radar sensor
●Keep the sensor and its surrounding area on the bumper clean at all times.
●Do not subject the sensor or surrounding area on the bumper to a strong impact.
If the sensor moves even slightly off position, the system may malfunction and
vehicles that enter the detection area may not be detected. If the sensor or sur-
rounding area is subject to a strong impact, always have the area inspected by
your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor or surrounding area on the
bumper.
●Do not modify the sensor or surrounding area on the bumper.
●Do not paint the sensor or surrounding area on the bumper.
One Blind Spot Monitor sensor is installed
inside the left and right side of the vehicle
rear bumper respectively. Observe the fol-
lowing to ensure the Blind Spot Monitor can
function correctly.

4-5. Using the driving support systems
The Blind Spot Monitor function uses radar sensors to detect vehicles that
are traveling in an adjacent lane in the area that is not reflected in the out-
side rear view mirror (the blind spot), and advises the driver of the vehi-
cle’s existence via the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 11.5 ft. (3.5 m)
from the side of the vehicle
The first 1.6 ft. (0.5 m) from the side of
the vehicle is not in the detection area
Approximately 9.8 ft. (3 m) from
the rear bumper
Approximately 3.3 ft. (1 m) for-
ward of the rear bumper

CAUTION
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the
driver that a vehicle is present in the blind spot. Do not overly rely on the Blind Spot
Monitor function. The function cannot judge if it is safe to change lanes, therefore
over reliance could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore the
driver’s own visual confirmation of safety is necessary.

Driving
The Rear Cross Traffic Alert functions when your vehicle is in reverse. It
can detect other vehicles approaching from the right or left rear of the
vehicle. It uses radar sensors to alert the driver of the other vehicle’s exist-
ence through flashing the outside rear view mirror indicators and sound-
ing a buzzer.

CAUTION
■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Rear Cross Traffic Alert function is only an assist and is not a replacement for
careful driving. The driver must be careful when backing up, even when using the
Rear Cross Traffic Alert function. The driver’s own visual confirmation of behind
you and your vehicle is necessary and be sure there are no pedestrians, other vehi-
cles etc. before backing up. Failure to do so could cause death or serious injury.
According to conditions, the system may not function correctly. Therefore the
driver’s own visual confirmation of safety is necessary.

Turn the power switch to ON mode.
Turn the headlights on.
Press the Lexus night view switch.
The Lexus night view is displayed on
the Remote Touch screen.
To return the screen to its previous
state, press the switch again.

determines that it is currently night
time from the brightness of the sur-
rounding area, the Lexus night view
can be operated by pressing the
Lexus night view switch while the
headlights are on.
∗: If equipped
Lexus night view is a system which assists with nighttime driving.
Near-infrared rays are irradiated forward and an image converted
from the irradiated light is show n on the Remote Touch screen. The
image shows pedestrians, obstacles, and road conditions ahead of the
vehicle, which ar e difficult to see at nigh ttime with the naked eye.

NOTICE
■The near-infrared camera
●Make sure the front windshield is kept clean.
●System performance may deteriorate if rain water, condensation or ice adheres
to the camera. If you notice the inner lens of the camera is dirty, the garnish will
have to be replaced. Consult your Lexus dealer.
●Do not subject the camera to strong impacts, or disassemble the camera.
●As the alignment of the camera has been very finely adjusted, do not change or
remove the mounting.
●If the front windshield fogs up, defog the windshield using the front defroster.
●Do not dirty or scratch the camera lens.
●Night view may not function properly if an object is placed on the sensor, or any-
thing that blocks the sensor is affixed to the windshield.
Follow these precautions to avoid damage to
or incorrect operation of the Lexus night
view.

5-2. Using the air conditioning system and defogger
■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic key and turning the power switch to ON
mode will recall that key’s registered air conditioning settings.
●When the power switch is turned off, the current air conditioning settings will auto-
matically be registered to the electronic key that was used to unlock the vehicle.
The system may not operate correctly if more than one electronic key is in the vicinity
or if the smart access system with push-button start is used to unlock a passenger
door.
Settings for the electronic key and the corresponding door can be changed. Contact
your Lexus dealer.
■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 immedi-
ately after is pressed.
■Humidity sensor
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Selecting on will dehumidify the air from the outlets and defog the windshield effec-
tively.
●If you turn off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
A sensor, which detects humidity inside the
vehicle and the temperature of the wind-
shield, is provided to detect fog on the front
windscreen. Due to the sensor, when auto-
matic mode is set the air conditioning may
make the following controls:
●Changing the amount of air flow
●Changing the amount of air introduced from
outside when in outside air mode with the air
vents in the position
●Changing the settings of the air vents to
when the is set

5-2. Using the air conditioning system and defogger
■Operation of the air conditioning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to priori-
tize 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
■When the outside temperature falls to nearly 32 °F (0 °C)
The dehumidification function may not operate even when is selected.
■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 immedi- ately after the air conditioning system is started in automatic mode.
■Air conditioning filter
→ P. 6 9 2
■Customization
Settings (e.g. exhaust gas sensor sensitivity) can be changed.
(Customizable features: → P. 8 3 3 )

Interior features
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
NOTICE
■To prevent 12-volt battery discharge
Do not leave the air conditioning system on longer than necessary when the hybrid
system is off.
■Humidity sensor
Follow these points to avoid damaging the sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner on the sensor or subject it to strong impacts
●Do not stick anything on the sensor
