When a frontal collision seems likely, the system attempts to lessen vehicle’s damage. Two types of pre-collision system are available.
The brake-linked pre-collision system operates in conjunction with the braking operation of the driver. The radar type pre-collision system has a sensor that is used to detect an unavoidable frontal collision.
Based on the speed and amount of the driver’s braking operation, the system determines if emergency braking is being performed. If this determination is made, the seat belts are immediately retracted to increase the effectiveness of the pretensioners . In addition, the system also operates if the driver loses control of the vehicle.
If the pre-collision sensor detects that a collision is unavoidable, the pre-collision system will retract the seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses control of the vehicle. However, when the VSC system is disabled, the system will not operate in the event of skidding.
When there is a high possibility of a frontal collision, the system applies greater braking force in relation to how strongly the brake pedal is depressed.
Radar sensor (radar type only)
Detects vehicles or other obstacles on or near the road ahead and determines whether a collision is imminent based on the position, speed, and heading of the obstacles.
When traveling on a road with very light traffic and very little to reflect the radar waves emitted by the radar sensor, the system may decide that the radar sensor is dirty, even if the sensor is not actually dirty. The system will automatically restore itself when reflected radar waves are detected.
The sensor cannot detect plastic obstacles such as pylons. There may also be occasions when the radar sensor cannot detect pedestrians, animals, bicycles, motorcycles, trees, or snowdrifts.
Conditions that may trigger the system even if there is no possibility of collision
When the system is activated in the situations described above there is also a possibility that the seat belts will retract quickly and the brakes will be applied with a force greater than normal. When the seat belt is locked in the retracted position, stop the vehicle in a safe place, release the seat belt and refasten.
When a malfunction occurs due to sensor contamination, etc. that results in the sensors being unable to detect obstacles, the pre-collision system will be automatically disabled. In this case, the system will not activate even if there is a collision possibility.
Warning lights and/or warning messages will turn on or flash.
FCC ID: HYQDNMWR005
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
Radiofrequency radiation exposure Information: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance of 20 cm between the radiator (antenna) and your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Observe the following to ensure the pre-collision system can function effectively.
Clean the sensor and front grille with a soft cloth so you do not mark or damage them.
If the sensor moves even slightly off position, the system may become inaccurate or malfunction. If the sensor or surrounding area are subject to a strong impact, always have the area inspected and adjusted by your Toyota dealer.
Do not rely on the pre-collision system. Always drive safely, taking care to observe your surroundings and checking for any obstacles or other road hazards.
Failure to do so may cause an accident resulting in death or serious injury.
