2184-5. Using the driving support systems
■The system can be operated when
●The engine switch is in IGNITION ON
mode.
●Intuitive parking assist function is on.
●The vehicle speed is less than about 6
mph (10 km/h).
●A shift lever is shifted to a position other
than P.
■Setting the buzzer volume
The buzzer volume can be adjusted on the
multi-information display. ( P.215)
■If “Parking Assist Unavailable Clean
Parking Assist Sensor” is displayed on
the multi-information display
A sensor may be covered with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low
temperatures, a warning message may be
displayed or the sensor may not be able to
detect an object. Once the ice melts, the system will return to normal.
■If “Parking Assist Unavailable” is dis-
played on the multi-information display
●Water may be continuously flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
●Initialization may not have been per-
formed after a battery terminal was dis-
connected and reconnected. Initialize the
system. (
P.218)
If this message continues to be displayed
even after initializati on, have the vehicle
inspected by your Lexus dealer.
■If a battery terminal has been discon-
nected and reconnected
The system needs to be initialized. To initial-
ize the system, drive the vehicle straight
ahead for 5 seconds or more at a speed of
approximately 22 mph (35 km/h) or more.
Additionally, for vehicles with the Parking
Support Brake function, turn the steering
wheel fully to the left and right with the vehi-
cle stopped.
■Sensor detection information
●The sensor’s detection areas are limited
to the areas around the vehicle’s front
and rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the object and other factors, the detection distance
may shorten, or detection may be impos-
sible.
• There will be a short delay between object detection and display. Even at low
speeds, there is a possibility that the
object will come within the sensor’s
detection areas before the display is
shown and the warning beep sounds.
• It might be difficult to hear the buzzer due to the volume of the audio system or air
flow noise of the air conditioning system.
• It may be difficult to hear the buzzer if
buzzers for other systems are sounding.
■Objects which the system may not prop-
erly detect
The shape of the object may prevent the
sensor from detecting it. Pay particular
WARNING
■When to disable the function
In the following situations, disable the
function as it may operate even though
there is no possibility of a collision.
●Failing to observe the warnings above.
●A non-genuine Lexus suspension
(lowered suspension, etc.) is installed.
■Notes when washing the vehicle
Do not apply intensive bursts of water or
steam to the sensor area. Doing so may
result in the sensor malfunctioning.
●When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●When using steam to clean the vehi-
cle, do not direct steam too close to
the sensors as doing so may cause a
sensor to malfunction.

cold environments.
■Rear side radar sensors
 P.209
■Operation of the RCTA function

■Parking Support Brake function
(static objects)
Ultrasonic sensors are used to detect
static objects, such as a wall, in the
detection area when driving at a low
speed or backing up. ( P.239)
■Parking Support Brake function
(rear-crossing vehicles)
Rear radar sensors are used to detect

PKSB (Parking Support
Brake)
*
The Parking Support Brake system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that the possibility of a colli-
sion with a detected object or
pedestrian is high, a warning oper-
ates to urge the driver to take eva-
sive action. If the system
determines that the possibility of a
collision with a detected object or
pedestrian is extremely high, the
brakes are automatically applied to
help avoid the collision or help
reduce the impact of the collision.

3026-1. Maintenance and care
Remove dirt using a water-damp-
ened soft cloth or synthetic chamois.
 Wipe the surface with a dry soft
cloth to remove any remaining
moisture.
■Cleaning the areas with satin-finish
metal accents
The metal areas use a layer of real metal for
the surface. It is necessary to clean them
regularly. If dirty areas are left uncleaned
for long periods of time, they may be diffi-
cult to clean.
 Remove dirt and dust using a vac-
uum cleaner.
 Wipe off any excess dirt and dust
with a soft cloth dampened with
diluted detergent.
Use a diluted water solution of approxi-
mately 5% neutral wool detergent.
Wring out any excess water from
the cloth and thoroughly wipe off all
remaining traces of detergent.
 Wipe the surface with a dry soft
cloth to remove any remaining
moisture. Allow the leather to dry in
a shaded and ventilated area.
■Caring for leather areas
Lexus recommends cleaning the interior of
the vehicle at least twice a year to maintain
the quality of the vehicle’s interior.
 Remove dirt and dust using a vac-
uum cleaner.
 Wipe it off with a soft cloth damp-
ened with neutral detergent diluted
to approximately 1%.
 Wring out any excess water from
the cloth and thoroughly wipe off
remaining traces of detergent and
water.
NOTICE
●Do not expose the vehicle to direct
sunlight for extended periods of time.
Park the vehicle in the shade, espe-
cially during summer.
●Do not place items made of vinyl, plas-
tic, or containing wax on the uphol-
stery, as they may stick to the leather
surface if the vehicle interior heats up
significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio sys-
tem may be damaged if water comes into
contact with electrical components such
as the audio system above or under the
floor of the vehicle. Water may also
cause the body to rust.
■When cleaning the inside of the wind-
shield
Do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
(  P.171)
■Cleaning the inside of the rear win-
dow
●Do not use glass cleaner to clean the
rear window, as this may cause dam-
age to the rear window defogger
heater wires or antenna. Use a cloth
dampened with lukewarm water to
gently wipe the window clean. Wipe
the window in strokes running parallel
to the heater wires or antenna.
●Be careful not to scratch or damage
the heater wires or antenna.
