RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)WARNING ■
When using the intuitive parking assist
Observe the following precautions.
Failing to do so may result in the vehicle be ing unable to be driv en safely and possibly
cause an accident. ●
Do not use the sensor at speeds in excess of 6 mph (10 km/h). ●
The sensors’ detection areas and reaction ti mes are limited. When moving forward or
reversing, check the areas surrounding the vehicle (especially th e sides of the vehi-
cle) for safety, and drive slowly, using the brake to control the vehicle’s speed. ●
Do not install accessories within the sensors’ detection areas.■
Limitations of the sensors ●
RC350/RC300: The detection areas of the sensors are limited to the areas around
the vehicle’s front and rear bumpers. ●
RC F: The detection areas of the sensors are limited to the areas around the vehicle’s
front corners and the rear bumpers. ●
Certain vehicle conditions and surrounding environments, such as the following, may
affect the ability of th e sensors to correctly detect obje cts. Pay particul ar attention in
the following situations. Failure to do so may result in the vehicle being driven
unsafely, possibly leading to an accident.
• When there is dirt, snow or ice on a se nsor (Cleaning the sensor will resolve this
problem.)
• When 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 objects may not be detected
• When a sensor is covered in any way
• When the vehicle is leaning considerably to one side
• When driving on an extremely bump y road, incline, gravel, or grass
• When 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
• When there is another vehicle equipped with parking assist sensor in the vicinity
• When the sensor is coated with a sheet of spray or heavy rain
• When the vehicle is equipped with a fender pole or wireless antenna
• When a towing eyelet is installed
• When a bumper or sensor receives a strong impact
• When the vehicle is approaching a tall or curved curb
• When driving in harsh sunlig ht or intense cold weather
• When an object is directly under a bumper
• When objects become too close to the sensors
• When a non-genuine Lexus suspension (lowered suspension, etc.) is installed
In addition to the situations above, there are instances in which, because of their
shape, signs and other objects may be judged by the sensor to be closer than they
are.

Driving
RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)WARNING ●
The shape of an object may prevent the sens or from detecting it. Pay particular atten-
tion to the following:
• Wires, fences, ropes, etc.
• Cotton, snow and other materi als that absorb sound waves
• Sharply-angled objects
• Low objects
• Tall objects with upper sections projecting outwards in the direction of your vehi-
cle
• People, animals and other moving objects
• People wearing certain types of clothing ●
The following situations may occur when using the Lexus parking assist-sensor.
• Depending on the shape of the object and other factors, the detection distance
may be shortened, or detection may not be possible.
• Objects may not be detected if they are too close to a sensor.
• There will be a short delay between the de tection of an object and display of the
detection. Even at slow speeds, there is a possibility that the object will come
within a sensor’s detection area before the display is shown and a warning beep
sounds.
• Thin posts or objects lower than a sensor 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 co nditioning system.
NOTICE ■
When using intuitive parking assist
In the following situations, the system may not function correctly due to a sensor mal-
function etc. Have the vehicle checked by your Lexus dealer. ●
The intuitive parking assist operation display flashes, and a beep sounds when no
obstacles are detected. ●
If the area around a sensor co llides with something, or is subjected to strong impact.●
If the bumper or grille collides with something. ●
If the display flashes or is displayed contin uously and a buzzer does not sound, except
when the mute function has been turned on.●
If a display error occurs , first check the sensor.
If the error occurs even when there is no ice, snow or mud on the sensor, it is likely that
the sensor is malfunctioning.■
Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in th e sensor malfunctioning.

WARNING ■
Handling the radar sensor
Blind Spot Monitor sensors ar e installed behind the left and right sides of the rear
bumper respectively. Observe the following to ensure the Blind Spot Monitor can
function correctly.
●
Do not subject a sensor or its surrounding area on the rear bumper to a strong
impact.
If a sensor is moved even slightly off po sition, the system may malfunction and vehi-
cles may not be detected correctly.
In the following situations , have your vehicle inspected by your Lexus dealer.
• A sensor or its surrounding area is subject to a strong impact.
• If the surrounding area of a sensor is sc ratched or dented, or part of them has
become disconnected. ●
Do not disassemble the sensor. ●
Do not attach stickers to the sensor or surrounding area on the rear bumper.●
Do not modify the sensor or surro unding area on the rear bumper.●
Do not paint the rear bumper any colo r other than an official Lexus color.●
Keep the sensors and the surrounding areas
on the rear bumper clean at all times.
If a sensor or its surrounding area on the rear
bumper is dirty or covered with snow, the
Blind Spot Monitor may not operate and a
warning message (  P. 471) will be displayed.
In this situation, clear off the dirt or snow and
drive the vehicle with the operation condi-
tions of the BSM function (  P. 295) satisfied
for approximately 10 minutes. If the warning
message does not disappear, have the vehicle
inspected by your Lexus dealer.

WARNING ■
Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The RCTA function is only a supplementary function which alerts the driver that a vehi-
cle is approaching from the right or left at the rear of the vehicle. As the RCTA function
may not function correctly under certain cond itions, the driver’s own visual confirma-
tion of safety is necessary. Over reliance on this function may lead to an accident
resulting death or serious injury.
