Forward Obstruction Warning (FOW) detects vehicles or obstacles in front of the car using a millimeter-wave radar. The system calculates the distance to the object in front and, if the car gets close enough that there is a risk of collision, sounds an alarm and displays a visual alert, prompting the driver to apply the brake.
* FOW may not perform as expected due to factors such as the shape of the vehicle in front (some shapes do not reflect radar well, etc.), bad weather (rain, snow, fog, etc.), and road conditions (multiple curves, undulations, etc.).
* FOW is designed to reduce the risk of accidents by warning the driver that there is a risk of a collision. However the system has its limitations, and no safety system or combination of such systems can prevent all accidents. These systems are not a replacement for safe and attentive driving. Please drive carefully at all times and do not rely on technology to prevent an accident. Not all of these systems are available on all models or in all markets, so please contact your local Mazda dealer for details on availability. Please refer to your owners' manual for additional important system details, limitations and warnings.
