Parking Sensors Explained
Detect obstacles around the car and beep faster the closer you get.
What are Parking Sensors?
Parking sensors use ultrasonic pulses to measure the distance between your car and nearby objects — kerbs, walls, other cars — then warn you with beeps.
How do they work?
Small round sensors set into the bumper send out an inaudible 'chirp' and time how long the echo takes to come back. The shorter the time, the closer the object, and the faster the beeping becomes.
What does it feel like?
Slow, occasional beeps as you approach a wall, building into a continuous tone when you're a few centimetres away. Most cars also show a graphic on the dashboard.
Benefits
- ✓Easier parking in tight spaces
- ✓Reduces bumper scrapes
- ✓Useful for taller vehicles with poor rearward views
- ✓Works in low light
Limitations
Dirt, snow or ice on the sensors can cause false alarms or missed objects. Very thin posts and low kerbs can be missed entirely.
