the surrounding conditions and operat-
ing the steering wheel to correct the path
of the vehicle. Also, the driver must take
adequate breaks when fatigued, such as

■If “Clean Parking Assist Sensor” is dis-
played on the multi-information display
A sensor may be dirty or covered with snow
or ice. In such cases, if it is removed from
the sensor, the system should return to nor-
mal.
Also, due to the sensor being frozen at low
temperatures, a malfunction display may
appear or an obstacle may not be detected.
If the sensor thaws out, the system should
return to normal.
■If “Parking Assist Malfunction” or
“Parking Assist Malfunction Visit Your
Dealer” is displayed on the multi-infor-
mation display
There is a malfunction and the device may
not be working properly.
Have the vehicle inspected by your Lexus
dealer.
■Sensor detectio n information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front
and rear bumpers.
●Certain vehicle conditions and the sur-
rounding environment may affect the
ability of the sensor to correctly detect
obstacles. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on the sensor.
(Wiping the sensors will resolve this
problem.)
• The sensor is frozen. (Thawing the area
will resolve this problem.)
In especially cold weather, if a sensor is
frozen the screen may show an abnormal
display, or obstacles may not be
detected.
• The sensor is covered in any way.
• The vehicle is leaning considerably to
one side.
• On an extremely bumpy road, on an
incline, on gravel, or on grass.
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines, air
brakes of large vehicles, or other loud
noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensor in the vicinity.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• Towing eyelets are installed.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low- ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are
instances in which, be cause of their shape,
signs and other objects may be judged by
the sensor to be closer than they are.
●The shape of the obstacle may prevent
the sensor from detecting it. Pay particu-
lar attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections pro- jecting outwards in the direction of your
vehicle
●The following situations may occur
during use.
• Depending on the shape of the obstacle and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• Obstacles may not be detected if they are too close to the sensor.
• There will be a short delay between obstacle detection and display. Even at
slow speeds, there is a possibility that the
obstacle will come within the sensor’s
detection areas befo re the display is
shown and the warning beep sounds.
• Thin posts or object s lower than the sen-
sor may not be detected when
approached, even if they have been
detected once.
• It might be difficult to hear beeps due to the volume of the audio system or air flow
noise of the air conditioning system.
• It might be difficult to hear beeps due to the sounds of other systems.

Maintenance and care
NOTICE
●Do not open the soft top roof with dirt
or snow adhered.
■Cleaning the soft top roof
Do not strongly press a soft brush such
as a horsehair brush or an adhesive roller
to the soft top roof. Doing so may cause
damage to the soft top roof.
■Cleaning the exterior lights
●Wash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights.
●Do not apply wax to the surfaces of the
lights.
Wax may cause damage to the lenses.
■When using an automatic car wash
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wip-
ers may operate and the wiper blades
may be damaged.
■When using a high-pressure car wash
●When washing the vehicle, do not let
water from the high -pressure washer
directly hit the camera, the area
around the camera or inside of the
outside door handles. Due to the
shock from high-pressure water, it is
possible that the device may not oper-
ate normally.
●Do not bring the nozzle tip close to
boots (rubber or re sin manufactured
cover), connectors or the following
parts. The parts may be damaged if
they come into contact with high-pres-
sure water.
• Traction related parts
• Steering parts
• Suspension parts
• Brake parts
●Keep the cleaning nozzle at least 11.9
in. (30 cm) away from the vehicle
body. Otherwise resin section, such as
moldings and bumpers, may be
deformed and damaged. Also, do not
continuously hold the nozzle in the
same place.
●Do not spray the lower part of the
windshield continuously. If water
enters the air conditioning system
intake located near the lower part of
the windshield, the air conditioning
system may not operate correctly.
●Do not wash the underside of the vehi-
cle using a high pressure car washer.
