If a vehicle is detected ahead of you when ACC is turned on, the system maintains, accelerates, or decelerates your vehicle’s set speed to keep the vehicle’s set following interval from the vehicle ahead.
If a vehicle detected ahead of you slows down abruptly, or if another vehicle cuts in front of you, a beep sounds and BRAKE appears on the
multi-information display to alert you
and the head-up warning lights*1 flash.
When your vehicle speed drops below 22 mph (35 km/h), ACC will automatically cancel and no longer will apply your vehicle’s brakes.
Always be prepared to apply the brake pedal when conditions require.
