The Ultrasonic misacceleration Mitigation System (UMS) operates to prevent sudden starts and mitigate collision-caused damages by suppress-
ing the engine output for up to approximately 5 seconds when the system judges that the system is detected the vehicle or obstacles within ap-
proximately 4 m in front and behind your vehicle and judges that accelerator pedal was depressed promptly and too strongly such as misopera-
tion of it. This system operates when the vehicle is at stop or moving forward is backward at less than approximately 10 km/h (6 mph).
When the UMS operates, the warning display appears on the information screen of the multi-information display, and the buzzer sounds intermit-
tently.
