Equipment adaptive/mobility
Summary
Some customers may complain about the following symptoms occurring when driving without anything ahead (no metallic object reflects the radar wave such as a vehicle ahead, an oncoming vehicle, a road sign or a guard rail). While using Mazda Radar Cruise Control (MRCC), the MRCC cancels by itself. NOTE: The customer may misinterpret MRCC cancellation as unintended braking. MRCC cancellation feels the same as the steering wheel cancel button being pressed or the brake pedal being tapped.
