Collision warning

Collision Warning helps prevent common traffic accidents as forward-looking, long-distance radar identifies potential obstacles.
When the danger of a collision is detected, the system warns the driver with an authoritative beep and a simultaneous red warning light projected on the windshield above the instrument panel.
These warnings should be enough to allow the driver to brake before a potential accident. Collision warning also provides emergency brake support which enables harder, quicker deceleration to help drivers stop or reduce speed to lessen the impact of a collision.
