2016 Toyota Prius: Front Traffic Sensors
by Josh Sadlier, Senior Editor on June 23, 2016
Front parking sensors are a nice feature to have — when you're parking. When you're creeping along in bumper-to-bumper traffic? Not so much.
I've driven a whole lot of cars with front parking sensors, and not once have I triggered them while sitting in traffic. Maybe there's just something about our 2016 Toyota Prius that emboldens me to get really close to the car ahead, but whatever the case, I got multiple such warnings yesterday on the slow commute home.
Here's a video. It doesn't look like I'm that close, does it? But beep-beep-beep, there it is. And once it starts beeping, there's no "serenity now!" button. It doesn't stop until the proximity situation is resolved, which means waiting for the car ahead to inch forward. During rush hour, that can take a while.
The Prius manual (page 339) states that the front parking sensors are triggered at a distance of 3.3 feet. Doesn't seem too conservative, but maybe it is compared to other systems.
All I know is, if my Prius had this feature, I'd be inclined to turn it off in traffic and then reactivate it for parking purposes. Fortunately, the control interface (see top photo) stays active on the instrument panel until you tell it to go away, and you just press a button on the steering wheel to turn the system on or off.
Still, not ideal.
