The Estima front camera is designed to work at low speeds under about 15 km/h. The system is activated with a button near the driver’s right knee (the very left side button in the above picture) and operates automatically when parking and stopped at intersections.
As the Estima slows down, the camera display comes up on the factory TV screen in the centre console using a splitscreen for left and right sides of the car. Being placed as far forward as possible on the vehicle, this allows the driver better vision of the front of the car and also cars approaching from both sides.
In some situations this front camera can be incredibly useful and makes parking in tight spaces much easier. It is not a very common option in Japan but we can source Estimas with it if this is important to you.
