Lexus ES: Intuitive parking assist

The distance from your vehicle to objects, such as a wall, when parallel parking or maneuvering into a garage is measured by the sensors and communicated via the multi-information display, head-up display (if equipped), Center Display and a buzzer. Always check the surrounding area when using this system.

System components

■ Types of sensors

1. Front corner sensors
2. Front center sensors
3. Rear corner sensors
4. Rear center sensors

■ Display When the sensors detect an object, such as a wall, a graphic is shown on the multi-information display, head-up display (if equipped) and Center Display depending on the position and distance to the object.

• Multi-information display and head-up display

1. Front corner sensor detection
2. Front center sensor detection
3. Rear corner sensor detection
4. Rear center sensor detection

• Center Display

A graphic is shown when the Lexus parking assist monitor (if equipped) is displayed.

A simplified image is displayed on the Center Display when an object is detected.

• When the shift lever is in R

• When the shift lever is in N, S or D (vehicle moving forward)

When an object is detected, a graphic will be displayed on the panoramic view monitor (if equipped).

Turning intuitive parking assist on/off

Use the meter control switches to enable/disable the Lexus parking assist-sensor.

To re-enable the system, select on the multi-information display, select and turn it on. If the system is disabled, it will remain off even if the power switch is turned to ON mode after the power switch has been turned off.

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 vehicle) for safety, and drive slowly, using the brake to control the vehicle's speed.
• Do not install accessories within the sensors' detection areas.
• The area directly under the bumpers is not detected. Thin posts or objects lower than the sensor may not be detected when approached, even if they have been detected once.

■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.

• The vehicle is equipped with a fender pole, wireless antenna or fog lights.

• The front or rear bumper or a sensor receives a strong impact.

• A non-genuine Lexus suspension (lowered suspension, etc.) is installed.

• Towing eyelet is 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 malfunction, etc. Have the vehicle checked by your Lexus dealer.

• The intuitive parking assist operation display flashes or shows continuously, and a buzzer sounds when no objects 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.

• When using a high pressure washer to wash 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.

■The system can be operated when

• The power switch is in 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.

■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 normal.

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 displayed 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 normal.
• Initialization may not have been performed after a 12-volt battery terminal was disconnected and reconnected. Initialize the system. If this message continues to be displayed even after initialization, have the vehicle inspected by your Lexus dealer.

■If a 12-volt battery terminal has been disconnected and reconnected The system needs to be initialized. To initialize 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 vehicle 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 impossible.
  • 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.

■Conditions under which the function may not function correctly Certain vehicle conditions and the surrounding environment may affect the ability of a sensor to correctly detect objects. Particular instances where this may occur are listed below.

• There is dirt, snow or ice on a sensor.

  (Cleaning the sensors will resolve this problem.)

• A sensor is frozen. (Thawing the area will resolve this problem.) In especially cold weather, if a sensor is frozen the sensor display may be displayed abnormally, or objects, such as a wall, may not be detected.
• A sensor is covered in any way.
• When a sensor or the area around a sensor is extremely hot or cold.
• 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 sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• If a sensor is hit by a large amount of water, such as when driving on a flooded road.
• If the vehicle is significantly tilted.
• The vehicle is approaching a tall or curved curb.
• If objects draw too close to the sensor.

■Objects which may not be properly detected The shape of the object may prevent the sensor from detecting it. Pay particular attention to the following objects:

• 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 vehicle

People may not be detected if they are wearing certain types of clothing.

Sensor detection display, object distance

■ Detection range of the sensors

1. Approximately 3.3 ft. (100 cm)
2. Approximately 4.9 ft. (150 cm)
3. Approximately 2.0 ft. (60 cm)

The diagram shows the detection range of the sensors. Note that the sensors cannot detect objects that are extremely close to the vehicle.

The range of the sensors may change depending on the shape of the object, etc.

■ Multi-information display, head-up display (if equipped) and Center Display When an object is detected by a sensor, the approximate distance to the object will be displayed on the multi-information display, Center Display, and head-up display.

(As the distance to the object becomes short, the distance segments may blink.)

• Approximate distance to object: 4.9 ft. (150 cm) to 2.0 ft. (60 cm)*(Rear center sensor)

*: Automatic buzzer mute function is enabled.

• Approximate distance to object: 3.3 ft. (100 cm) to 2.0 ft. (60 cm)* (Front center sensor)

*: Automatic buzzer mute function is enabled.

• Approximate distance to object: 2.0 ft. (60 cm) to 1.5 ft. (45 cm)*

*: Automatic buzzer mute function is enabled.

• Approximate distance to object: 1.5 ft. (45 cm) to 1.0 ft. (30 cm)*

*: Automatic buzzer mute function is enabled.

• Approximate distance to object: 1.0 ft. (30 cm) to 0.5 ft. (15 cm)*1

*1: Automatic buzzer mute function is disabled.
*2: The distance segments will blink slowly.

• Approximate distance to object: Less than 0.5 ft. (15 cm)*1

*1: Automatic buzzer mute function is disabled.
*2: The distance segments will blink rapidly.

■ Buzzer operation and distance to an object A buzzer sounds when the sensors are operating.

• The buzzer beeps faster as the vehicle approaches an object. When the vehicle comes within the following distance of the object, the buzzer sounds continuously: Approximately 1.0 ft. (30 cm)
• When 2 or more objects are detected simultaneously, the buzzer sounds for the nearest object. If one or more objects come within approximately 1.0 ft. (30 cm) of the vehicle, the buzzer will repeat a long tone, followed by fast beeps.
• Automatic buzzer mute function: After a buzzer begins sounding, if the distance between the vehicle and the detected object does not become shorter, the buzzer will be muted automatically. (However, if the distance between the vehicle and object is 1.0 ft. [30 cm] or less, this function will not operate.)

The buzzer sounds volume can be adjusted.
