NOTICE
Camera sensor (P. 274)
Observe the following to ensure that the LKA system functions correctly.
Keep the windshield clean at all times.
Performance could be affected if the windshield is dirty, or if raindrops,
condensation or ice are adhering to the windshield.
When adjusting the rear view mirror, make sure that it does not block the
camera lens.
Do not attach window tinting to the windshield.
Do not install an antenna in front of the camera lens.
If the windshield is fogged up, use the windshield defogger to remove fog
from the windshield.
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.
Do not place anything on the dashboard.
The camera sensor may recognize the image reflected on the windshield
as lane markers by mistake.
Do not scratch the camera lens, or let it get dirty.
When cleaning the inside of the windshield, be careful not to get any glass
cleaner etc. on the lens. Also, do not touch the lens.
For lens repair, contact any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.

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 dis-
assemble the camera sensor.

CAUTION
When using the Lexus parking assist monitor system
When backing up, be sure to check visually behind and all around the vehi-
cle before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
The parking assist monitor is a supplemental device intended to assist the
driver when backing up. Never depend on the parking assist monitor
entirely when backing up. Always make sure your intended path is clear.
Use caution, just as you would when backing up any vehicle.
Never back up while looking only at the screen.
The image shown on the screen may differ from the actual state, and you
could collide with another vehicle or obstacles if backing up looking only
at the screen, possibly causing an accident. When backing up, be sure to
check in front of and behind the vehicle, both directly and with mirrors.
Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
If you seem likely to hit nearby vehicles, obstacles, people or mount the
shoulder, depress the brake pedal to stop the vehicle, then disable the
assist system by select on the screen to cancel the system.
The instructions given are only guidelines.
When and how much to turn the steering wheel will vary according to
traffic conditions, road surface conditions, vehicle condition, etc. when
parking. It is necessary to be fully aware of this before using the parking
assist system.
When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
Do not use system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or emergency tires
• When the trunk lid is not closed completely
• On roads that are not flat or straight, such as curves or slopes.

CAUTION
In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to check direct
visually and with mirror all around the vehicle before proceeding.
If the tire sizes are changed, the position of the guide lines displayed on
the screen may change.
The camera uses a special lens. The distances between objects and pedes-
trians that appear in the image displayed on the screen will differ from the
actual distances. (P. 316)
When using the perpendicular parking assist screen
The position of the guide lines displayed on the screen may change in
accordance with the number of passengers, the amount of cargo etc. Be
sure to check behind and all around the vehicle direct visually and with
mirror before proceeding.
Estimated course line display mode: If the steering wheel is straight and
the vehicle width extension guide lines and the estimated course lines are
not in alignment, have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
The vehicle width extension guide lines are wider than the actual width of
the vehicle. When backing up, be sure to check behind and all around the
vehicle direct visually and with mirror before proceeding.
When using the parallel parking assist screen
Do not use the system if the display is incorrect due to an uneven (curvy/
hilly) road or a non-straight road.
Make sure to operate the steering wheel only when the vehicle is stopped.
Be sure to check that there are no obstacles inside the blue outline.
If there are any obstacles inside the blue outline, do not use the parallel
parking assist.
When positioning the blue outline over the parking space, be sure to posi-
tion it so that the extended blue line may not cross the tire of the vehicle
parked in front of the empty space.

BSM (Blind Spot Monitor)
: If equipped
The Blind Spot Monitor is a system that assists the driver to con-
firm safety when changing lanes.
The system uses radar sensors to detect vehicles that are traveling
in an adjacent lane in the area that is not reflected in the outside
rear view mirror (the blind spot), and advises the driver of the vehi-
cles existence via the outside rear view mirror indicator.
BSM main switch
Pressing the switch turns the system on or off. When the switch is set to
on, the switch’s indicator illuminates.
Outside rear view mirror indicator
When a vehicle is detected in the blind spot, the outside rear view mirror
indicator on that side illuminates. If the turn signal lever is operated when
a vehicle is in the blind spot, the outside rear view mirror indicator
flashes.
