When the sensors detect an obstacle, the following displays inform the driver of the position and distance to the obstacle.

• Multi-information display
  1. Front corner sensor opera-tion
  2. Rear corner sensor operation
  3. Rear center sensor operation
  4. Select to mute the buzzer sounds.
• Audio/visual system screen
  Insert display
  When the rear view monitor sys-tem is displayed. A simplified image is displayed on the right upper corner of the audio/visual system screen when an obstacle is detected.
• Muting the buzzer sound
  • To mute the buzzer sound
    The buzzer can be temporarily muted by pressing of the meter control switches while an obstacle detection display is shown on the multi-informa-tion display.
  • To cancel the mute
    Mute will be automatically canceled in the following situations.
    • When the shift position is changed
    • When the vehicle speed has reached or exceeded approximately 6 mph (10 km/h) with the shift lever in D
    • When the intuitive parking assist is turned off once and turned on again
    • Vehicles without a smart key system: When the engine switch is turned off once and turned to “ON” position again Vehicles with a smart key system: When the engine switch is turned off once and turned to IGNITION ON mode again
    • When a sensor is malfunctioning

Sensor detection display, obstacle distance

Distance display
Sensors that detect an obstacle will illuminate continuously or blink.

• Buzzer operation and distance to an obstacle
  A buzzer sounds when the sensors are operating.
• The buzzer sounds faster as the vehicle approaches an obstacle. When the vehicle comes within the following distance of the obstacle, the buzzer sounds continuously.
  • Front and rear corner sensors: Approximately 0.8 ft. (25 cm)
  • Rear center sensors: Approximately 1.1 ft. (35 cm)
• When 2 or more obstacles are detected simultaneously, the buzzer system responds to the nearest obstacle. If one or both come within the above distances, the beep will repeat a long tone, followed by fast beeps.

Detection range of the sensors

1. Approximately 2.0 ft. (60 cm)
2. Approximately 2.0 ft. (60 cm)
3. Approximately 5.9 ft. (180 cm)
   The diagram shows the detection range of the sensors. Note that the sensors cannot detect obstacles that are extremely close to the vehicle. The range of the sensors may change depending on the shape of the object tc.

• The intuitive parking assist can be operated when
  • The engine switch is in the “ON” position (vehicles without a smart key sys-tem) or IGNITION ON mode (vehicles with a smart key system).
  • Front corner sensors:
    • The shift lever is not in P.
    • The vehicle speed is approximately 6 mph (10 km/h) or less.
  • Rear corner and rear center sensors:
    • The shift lever is in R.
• Intuitive parking assist display
  When an obstacle is detected while the rear view monitor system or pan-oramic view monitor (if equipped) is in use, the warning indicator will appear in the upper part of the screen even if the display setting has been set to off.
  Sensor detection information
  • The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
  • Depending on the shape of the obstacle and other factors, the detection dis-tance may shorten, or detection may be impossible.
  • Obstacles may not be detected if they are too close to the sensor.
  • There will be a short delay between obstacle detection and display. Even at slow speeds, there is a possibility that the obstacle will come within the sen-sor’s detection.
  • Thin posts or objects lower than the 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 audio/visual system or air flow noise of the air conditioning system.
• Certification (Canada only)
  This ISM device complies with Canadian ICES-001. Cet appareil ISM est conforme a la norme NMB-001 du Canada.

WARNING

• When using the Intuitive parking assist-sensor Observe the following precautions. Failure 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.
• Sensors
  Certain vehicle conditions and the surrounding environment may affect the ability of a sensor to correctly detect an obstacle. Particular instances where this may occur are listed below.
  • There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this problem.)
  • 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 obstacles may not be detected.
  • The sensor is covered in any way.
  • The vehicle is leaning considerably to one side.
  • 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 ultra-sonic waves.
  • There is another vehicle equipped with parking assist sensors in the vicin-ity.
  • The sensor is coated with a sheet of spray or heavy rain.
  • The sensor is drenched with water on a flooded road.
  • The vehicle is equipped with a fender pole or wireless antenna.
  • Towing eyelets are installed.
  • The bumper or sensor receives a strong impact.
  • The vehicle is approaching a tall or curved curb.
  • The detection range is reduced due to an object such as a sign.
  • In harsh sunlight or intense cold weather.
  • The area directly under the bumpers is not detected.
  • If obstacles draw too close to the sensor.
  • A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
  • A backlit license plate is installed.

In addition to the examples above, there are instances in which, because of their shape, signs and other objects may be judged by a sensor to be closer than they are.

• Obstacles which may not be properly detected
  The shape of the obstacle may prevent a sensor from detecting it. Pay par-ticular attention to the following obstacles:
  • Wires, fences, ropes, etc.
  • Cotton, snow and other materials that absorb sound waves
  • Sharply-angled objects
  • Low obstacles
  • Tall obstacles with upper sections projecting outwards in the direction of your vehicle
  • People may not be detected if they are wearing certain types of clothing.
  • Moving objects such as people or animals

NOTICE

• 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 Toyota dealer.
  • The intuitive parking assist operation display flashes, and a buzzer sounds when no obstacles are detected.
  • If the area around a sensor collides with something, or is subjected to strong impact.
  • If the bumper collides with something.
  • If the display shows continuously without beeping, except when the buzzer volume is muted.
  • If a display error occurs, first check the sensor. If the error occurs even if 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.

Driving assist systems

To keep driving safety and performance, the following systems operate automatically in response to various driving situations. Be aware, however, that these systems are supplementary and should not be relied upon too heavily when operating the vehi-cle.

• ABS (Anti-lock Brake System)
  Helps to prevent wheel lock when the brakes are applied suddenly, or if the brakes are applied while driving on a slippery road surface
• Brake assist
  Generates an increased level of braking force after the brake pedal is depressed when the system detects a panic stop situation
• VSC (Vehicle Stability Control)
  Helps the driver to control skidding when swerving suddenly or turning on slippery road surfaces
• TRAC (Traction Control)
  Helps to maintain drive power and prevent the drive wheels from spinning when starting the vehicle or accelerating on slippery roads
• Hill-start assist control
  Helps to reduce the backward movement of the vehicle when start-ing on an uphill
• EPS (Electric Power Steering)
  Employs an electric motor to reduce the amount of effort needed to turn the steering wheel
• Active Torque Control 4WD (AWD models only)
• Automatically switches from front-wheel drive to AWD (All-Wheel Drive) according to driving conditions, helping to ensure reliable handling and stability. Examples of conditions where the system will switch to AWD are when cornering, going uphill, starting off or accelerating, and when the road surface is slippery due to snow or rain etc.
