WARNING

■

When using the intuitive parking assist
Observe the following precautions.

Failing to do so may result in the vehicle being unable to be driven 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 times are limited. When moving forward or

reversing, check the areas surrounding the vehicle (especially the 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 the sensors to correctly detect objects. Pay particular 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 sensor (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 bumpy 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 sunlight 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.

WARNING

●

The shape of an object may prevent the sensor from detecting it. Pay particular atten-

tion to the following:
• Wires, fences, ropes, etc.

• Cotton, snow and other materials 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 detection 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 conditioning 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 collides with something, or is subjected to strong impact.

●

If the bumper or grille collides with something.

●

If the display flashes or is displayed continuously 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 the sensor malfunctioning.

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 BSM function is a supplementary function which alerts the driver that a vehicle is in

a blind spot of the outside rear view mirrors or is approaching rapidly from behind into

a blind spot. Do not overly rely on the BSM function. As the function cannot judge if it is

safe to change lanes, over reliance could lead to an accident resulting in death or seri-

ous injury.
As the system may not function correctly under certain conditions, the driver’s own

visual confirmation of safety is necessary.
