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.

tion it so that the extended blue line may not cross the tire of the vehicle
parked in front of the empty space.

NOTICE
How to use the camera
The parking assist monitor may not operate properly in the following
cases, or if the precautions described below are not followed.
• If the back of the vehicle is hit, the position and mounting angle of the
camera may change.
• As the camera has a water proof construction, do not detach, disassem-
ble or modify it. This may cause incorrect operation.
• Do not strongly rub the camera lens. If the camera lens is scratched, it
cannot transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or glass coat to
adhere to the camera. If this happens, wipe it off as soon as possible.
• If the temperature changes rapidly, such as when hot water is poured on
the vehicle in cold weather, the system may not operate normally.
• When washing the vehicle, do not apply intensive bursts of water to the
camera or camera area. Doing so may result in the camera malfunction-
ing.
• When the camera is used under fluorescent lights, sodium light or mer-
cury light etc., the lights and the illuminated areas may appear to
flicker.
Do not expose the camera to strong impact as this could cause a malfunc-
tion. If this happens, have the vehicle inspected by any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as
soon as possible.
