What is front radar?
The front radar sensor facilitates fast, precise, and resilient object detection and tracking thanks to its long detection range, wide field of view, outstanding angle separability, and a new chirp-sequence modulation feature. This makes it ideally suited to complex traffic scenarios.
What is forward emergency braking?
When traffic slows unexpectedly, the system pushes the accelerator pedal up and applies partial braking. If a collision is likely, the system alerts you, braking harder so you can minimize or even prevent impact.
Why is my front collision light on?
Forward collision warning systems warn you of an impending collision by detecting stopped or slowly moved vehicles ahead of your vehicle. If there is an impending collision, the system will warn you of the danger using lights, beeps, vibrations of your seat, or a combination of these.

NEXRADs on the other hand, don’t suffer from this limitation, especially at the higher altitudes where most commercial aircraft operate. Another limitation of airborne weather radars is called shadowing or attenuation.
What makes a car have a faulty radar system?
Experts describe current automotive radar systems as “shortsighted”: “They lack the resolution to distinguish objects close to the vehicle, while discarded soda cans and other metallic objects can cause false alarms that increase the risk of accidents,” according to the trade magazine Microwaves & RF.
When does front radar obstructed warning come on?
“FEB: Front Radar Obstructed” warning appears on panel between tach and speedo. The “collision warning system inactive” icon light comes on.

Any ideas? Thanks.
