To make parking manoeuvres easier, the proximity sensors alert you at any obstacles in front or behind through sequences of beeps that get faster as you approach the object. This way the driver achieves easier parking manoeuvres, while protecting the body. An intermittent warning tone indicates how far the car is from an obstacle. As the distance decreases, the warning tone becomes faster. It first sounds when the car is 1.5 metres from the obstacle and sounds continuously when only 25 centimetres remain. The system use ultrasonic sensors that are installed at the rear as well as the front of the car. It can be switched off at the front in special situations such as stop-and go traffic, or people passing in front of the car. At the rear, the system switches on automatically when Reverse is selected
