■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 de tected doing so, the ACC with Low Speed
Follow system maintains or decelerates your vehicle’s set speed in order to keep the
vehicle’s set following-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 th e 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 resume s an appropriate speed for keeping the
following-interval wh ile a vehicle ahead is within the ACC with Low Speed Follow
range.
There are times when the vehicle speed will decrease when the accelerator pedal is
lightly applied.
1 When in Operation
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC with Low Speed
Follow may start accelerati ng 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, gradua lly 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 detect ing range. Change the ACC
Forward Vehicle Detect Beep setting.
