The parking sensors use ultrasonic sensors which detect obstructions around the vehicle when the vehicle is driven at low speeds, such as during garage or parallel parking, and a buzzer sound and detection indicator notify the driver of the approximate distance from the vehicle to the surrounding obstruction.
I never really noticed a sound when backing into something, but I haven't paid attention.
Do the higher trims come with trajectory? The base model does not. Really surprising omission. It could easily have been included, it's a matter of calculating steering angle, measuring/testing, and displaying the relevant angle. In fact, the straight lines are misleading unless you have your steering wheel pointed completely straight. Minor annoyance.
my sport has a audible warning when backing up if someone or thing
crosses line of sight........
Do the higher trims come with trajectory? ...
Trajectory lines from back-up camera on CX-5 are available in other regions for many years. Mazda just chose not to offer this feature to US customers. And I don*t believe you can add this feature by a software update as it*s a integrated system with infotainment system and front / rear parking sensors.My daughter*s Hyundai Sonata has the trajectory lines...really helpful. I wonder if that is a software generated feature that Mazda could add during an update?
The front sensors are integrated into the rear camera so it generates an image of the front and back sensors on the screen that drops out at about 3mph. Cars with HID headlights must have headlamp washers but not LEDs, don't ask me why!
The parking sensors show up on the rear camera screen too but no headlight washers and no rear camera washer as you can see!
The front sensors come on automatically immediately after having reversed OR they can be manually operated from a button on the dash. When you drive off they go off at about 5mph or you can push the switch again.
My 2019 touring has cross traffic alert but no alert for simply backing into things.
The camera is better than all others I've seen and I've used quite a lot in rental cars. Because of this, it surprised me when I saw one reviewer say the camera was low resolution.
