RX350/RX350L_U 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.●
The vehicle is equipped with a fender pole or wireless antenna. ●
The front or rear bumper or a se nsor receives a strong impact.●
A non-genuine Lexus suspension (lower ed suspension, etc.) is installed.●
Towing eyelets are installed. ●
A backlit license plate is installed. ■
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 disp lay flashes, and a buzzer 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 collides with something. ●
If the display shows continuously withou t beeping, except when the buzzer mute
switch has been turned on. ●
If a display error occurs , first check the sensor.
If the error occurs even if there is no ice, sn ow 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.●
When using a high pressure washer to wa sh the vehicle, do not spray the sensors
directly, as doing so may cause a sensor to malfunction. ●
When using steam to clean the vehicle, do not direct steam too close to the sensors
as doing so may cause a sensor to malfunction.

336 4-5. Using the driving support systems
RX350/RX350L_U The system will operate in situations such as the following if a stationary object is
detected in the traveling direction of the vehicle.
◆ When traveling at a low speed and the brake pedal is not depressed, or is
depressed late
 : If equippedIntelligent Clearance Sonar (ICS) If a collision with a wall or other stationary object may occur due to the vehicle
suddenly moving forward due to an ac cidental accelerator pedal operation,
the vehicle moving the unintended dire ction due to the wrong shift position
being selected, or while parking or trav eling at low speeds, the sensors detect
stationary objects, such as a wall, in th e traveling direction of the vehicle, and
the system operates to lessen an impact with a stationary object and reduce
the resulting collision damage.

Re-enabling the Intelligent Clearance Sonar system
To re-enable the Intelligent Clearance Sonar system when it is disabled due to operation
of the Intelligent Clearance Sonar function, either enable the system again (  P. 339), or
turn the engine switch off and th en back to IGNITION ON mode.
Additionally, if the object becomes no longer in the traveling directio n of the vehicle or if
the traveling direction of the vehicle change s (such as changing from moving forward to
backing up, or from backing up to moving fo rward), the system will be re-enabled auto-
matically. ■
Objects that the Intelligent Cleara nce Sonar function may not detect
The sensors may not be able to detect certain objects, such as the following. ●
Cotton cloth, snow, and other materials that are poor reflectors of ultrasonic waves.
(People may also not be detected depending on the type of clothing they are wearing.) ●
Objects which are not perpendicular to the ground, are not perpendicular to the travel-
ing direction of the vehicle, are uneven or are waving. ●
Low objects ●
Thin objects such as wires, fences, ropes and signposts ●
Objects that are extremely close to the bumper ■
Intuitive parking assist buzzer
Regardless of whether the in tuitive parking assist system is enabled or not (  P. 326), if
the Intelligent Clearance Sonar system is enabled (  P. 339), the front or rear sensors
detect an object and brake control is performed, the intuitive parking assist buzzer will
sound to notify the driver of the approximate distance to the object.

Re-enabling the Rear Cross Traffic Auto Brake function
To re-enable the Rear Cross Traffic Auto Brake function when it is disabled during opera-
tion of the Rear Cross Traffic Auto Brake function, either enable the system again (  P.
339), or turn the engine switch off and then back to IGNITION ON mode.
Additionally, if there is no longer a vehicle ap proaching from the right or left at the rear of
the vehicle, or if the traveling direction of the vehicle changes (such as changing from
moving forward to backing up or from backin g up to moving forward), the system will be
re-enabled automatically. ■
Conditions under which the Rear Cross Traffic Auto Brake function will not detect a
vehicle
The Rear Cross Traffic Auto Brake function is not designed to detect the following types
of vehicles and/or objects: ●
Vehicles approaching from directly behind ●
Vehicles backing up in a parkin g space next to your vehicle
●
Guardrails, walls, signs, parked vehi cles and similar stationary objects
*●
Small motorcycles, bicycles, pedestrians, etc.
*●
Vehicles moving away from your vehicle ●
Vehicles approaching from the parking spaces next to your vehicle
*
* : Depending on the conditions, detection of a vehicle and/or object may occur.■
RCTA function buzzer
Regardless of whether the RCTA function is enabled or not (  P. 315), if the Rear Cross
Traffic Auto Brake function is enabled and brake control is performed, a buzzer will
sound to notify the driver. ●
Vehicles that the sensors cannot detect due to
obstructions ●
Vehicles which suddenly accelerate or decel-
erate near your vehicle
