This manual describes the operating principle and use of the parking sensor on the Toyota Innova vehicle.
The document describes a parking aid system equipped with two audible warning devices that produce low-pitch acoustic signals for front detection and high-pitch signals for rear detection. The system activates when the gear is in 'P' or 'N' position, provided the parking brake is not engaged.
It details the specific operating conditions based on gear selection, parking brake status, and vehicle speed. The manual also defines the detection zones: an intermittent beep zone ranging from 50cm to 150cm and a continuous beep zone starting at approximately 30cm or less. General recommendations emphasize that the driver remains responsible for evaluating obstacles and notes limitations regarding low, thin, or pointed objects.
The system turns off and the LED indicator goes off when the vehicle speed is greater than 10km/h.
The system may fail to detect very low, thin, or pointed obstacles, as well as objects directly underneath the bumpers.
