Adaptive Cruise Control (ACC) with Low Speed Follow Helps maintain a constant vehicle speed and a set following-interval behind a vehicle detected ahead of yours and, if the detected vehicle comes to a stop, can decelerate and stop your vehicle, without you having to keep your foot on the brake or the accelerator. When ACC with Low Speed Follow slows your vehicle by applying the brakes, your vehicles brake lights will illuminate.

1Adaptive Cruise Control (ACC) with Low Speed Follow

Important Reminder As with any system, there are limits to ACC with Low Speed Follow. Use the brake pedal whenever necessary, and always keep a safe interval between your vehicle and other vehicles.

When driving at about 25 mph (40 km/h) or above: Take your foot off the pedal and press down the RES/+/SET/ switch when you reach the desired speed. The moment you release the switch, the set speed is fixed, and ACC with Low Speed Follow begins. When driving slower than about 25 mph (40 km/h): If the vehicle is moving and the brake pedal is not depressed, pressing the switch fixes the set speed to about 25 mph (40 km/h) regardless of current vehicle speed. If your vehicle is stationary, you can set the vehicle speed even with the brake pedal depressed.

There is a vehicle ahead ACC with Low Speed Follow monitors if a vehicle ahead of you enters the ACC with Low Speed Follow range. If a vehicle is detected doing so, the ACC with Low Speed Follow system maintains or decelerates your vehicles set speed in order to keep the vehicles set following-interval from the vehicle ahead.

2 To Set or Change Following-interval P. 442

When a vehicle whose speed is slower than your set speed is detected in front of you, your vehicle starts to slow down.

When in Operation 1When in Operation

If the vehicle detected ahead of you slows down abruptly, or if another vehicle is detected cutting in front of you, a beeper sounds and a message appears on the multi-information display, and the head-up warning lights* come on.

Depress the brake pedal, and keep an appropriate interval from the vehicle ahead.

There is no vehicle ahead Your vehicle maintains the set speed without having to keep your foot on the brake or accelerator pedal. If there previously was a vehicle detected ahead that kept your vehicle from traveling at the set speed, ACC with Low Speed Follow accelerates your vehicle to the set speed, and then maintains it.

When you depress the accelerator pedal You can temporarily increase the vehicle speed. In this case, there is no audible or visual alert even if a vehicle is in the ACC with Low Speed Follow range. ACC with Low Speed Follow stays on unless you cancel it. Once you release the accelerator pedal, the system resumes the set speed. There are times when the vehicle speed will decrease when the accelerator pedal is lightly applied.

A vehicle icon with dotted-line contour appears on the multi- information display

1When in Operation

Even if the interval between your vehicle and the vehicle detected ahead is short, ACC with Low Speed Follow may start accelerating your vehicle under the following circumstances: The vehicle ahead of you is going at almost the

same speed as, or faster than, your vehicle. A vehicle that cuts in front of you is going faster

than your vehicle, gradually increasing the interval between the vehicles.

You can also set the system to beep when a vehicle in front of you comes in and goes out of the ACC with Low Speed Follow detecting range. Change the ACC Forward Vehicle Detect Beep setting.
