Mazda 3 Owners Manual: Forward Obstruction Warning (FOW))
Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible collision using an indicator and warning sound in the instrument cluster while the vehicle is being driven at about 15 km/h or faster (10 mph or faster) and the system's radar sensor determines that your vehicle may hit a vehicle or obstruction ahead.
| WARNING Do not rely completely on the Forward Obstruction Warning (FOW) system and always drive carefully: Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of a collision. The ability to detect an obstruction is limited depending on the obstruction, weather conditions, or traffi c conditions. Therefore, if the accelerator pedal or brake pedal is mistakenly operated it could result in an accident. Always verify the safety of the surrounding area and depress the brake pedal or accelerator pedal while keeping a safe distance from vehicles ahead or on-coming vehicles. |
