Lexus parking assist monitor camera
The camera for the parking
assist monitor is located above
the license plate.
Using the camera
If the camera lens becomes dirty, it cannot transmit a clear
image. If water droplets, snow or mud adhere to the lens, rinse
with water and wipe with a soft cloth. If the lens is extremely
dirty, wash it with a mild cleanser and rinse.

lines may not actually be parallel with the dividing lines of the
parking space, even when they appear to be so. Be sure to check
visually.
The distances between the vehicle width extension guide lines
and the left and right dividing lines of the parking space may not
be equal, even when they appear to be so. Be sure to check visu-

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.
