CAUTION
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
position it so that the extended blue
line may not cross the tyre of the
vehicle parked in front of the empty
space.
If the extended line of the blue outline
is crossing the parked vehicle, your
vehicle may be too close. Check that
there is a gap of approximately 3 ft. (1
m) between your vehicle and the
parked vehicle.

when backing up at a very slow
speed.
If the trunk is opened during parallel
parking guidance, parallel parking
assist will be interrupted and can-
celed. Stop the vehicle, shift the shift
lever out of the “R” position, and

If the Lexus parking assist-sensor
detects an object while you attempt to
park in a parking space on the left, the
black and yellow vertical pole could be
obscured by the Lexus parking assist
display. In this event, turn the Lexus
parking assist-sensor off (P.311), and
operate the vehicle while checking the
safety of the surrounding area both
directly and using the mirrors. After the
operation, turn the switch on.
The steering wheel has been turned too
far, and the system cannot function.
Return the steering wheel to its original
position.
If the message is displayed before the
outline is positioned over the desired
parking space, it is likely that the vehi-
cle is too far away from the shoulder.
Check that there is a gap of approxi-
mately 3 ft. (1 m) between your vehicle
and the parked vehicle.

INFORMATION
The area displayed on the screen may
vary according to vehicle orientation
conditions.
Objects which are close to either cor-
ner of the bumper or under the

The camera uses a special lens. The
distance of the image that appears on
the screen differs from the actual dis-
tance.
Items which are located higher than
the camera may not be displayed on
the monitor.
If your vehicle is equipped with a
backlit number plate, it may interfere

THE CAMERA
The camera for the parking assist
monitor is located as shown in the il-
lustration.
USING THE CAMERA
If the camera lens becomes dirty, it
cannot transmit a clear image. If wa-
ter droplets, snow or mud adhere to
the lens, rinse with water and wipe
with a soft cloth. If the lens is ex-
tremely dirty, wash it with a mild
cleanser and rinse.
NOTICE
The parking assist monitor may not
operate properly in the following
cases.
• 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, disas-
semble 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 hap-
pens, 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 sys-
tem 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 malfunc-
tioning.
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.
