PARKING SENSOR SYSTEM [(E)]

id0922000242x2

Outline

• The parking sensor system detects obstructions in the blind spot (vehicle front/rear/corners/side) to a wide extent using ultrasonic sensors and notifies the driver of the obstructions using the indicator and buzzer.

Warning

• The parking sensor system is a device to assist the driver in confirming safety. It is not a substitute for the driver and cannot guarantee 100 % safety. Do not rely completely on the parking sensor system and drive while confirming the safety of the surrounding area visually.

• The following circumstances may obstruct the ultrasonic sensor resulting in an accident:

― Ice, snow, or dirt is adhering to ultrasonic sensor

― Ultrasonic sensor is covered by foreign matter (such as bumper stickers)

― Shock is applied to bumper in accident and ultrasonic sensor installation angle is deviated

― Ultrasonic sensor is exposed to heavy rain or water-spray from road

― There is another device emitting ultrasonic waves (such as ultrasonic sensor of another vehicle) near ultrasonic sensor

• The parking sensor system may not operate normally under the following conditions:

― Ice, snow, or dirt is adhering to ultrasonic sensor

― Ultrasonic sensor is frozen

― Vehicle is in tilted position

― Vehicle is parked on steep incline or there is difference in height between lines

― Obstructions have approached too close to ultrasonic sensor

• The ultrasonic sensor may not detect the following items:

― Thin objects such as wire or rope

― Items which absorb ultrasonic waves easily, such as cotton or snow

― Angular-shaped objects

― Tall objects protruding at the top

― Short objects

― Objects located immediately below bumper, such as wheel stoppers

• The warning alert may activate while driving near parked vehicles/guardrails/walls on a narrow road, or while driving on a slope, gravel road, or grass field. This is a normal effect caused by the system's response to ultrasonic waves, and does not indicate a malfunction.

Function

• The ultrasonic sensor located on the bumper detects an obstruction and the parking assist unit informs the driver of the distance between the vehicle and the obstruction using the parking sensor buzzer and the indicator light.

Ultrasonic sensor malfunction detection function

• If the parking assist unit detects that there is a malfunction in the ultrasonic sensor circuit, the sound is activated in the following pattern and flashes the indicator light.

Volume adjustment function

• The volume of the parking sensor buzzer can be adjusted. Refer to the [PERSONALIZATION FEATURES] in the workshop manual.

Detection indication setting change function

• The detection indication on the center display can be switched between display/non-display. Refer to the [PERSONALIZATION FEATURES] in the workshop manual.
