■There is a vehicle ahead
ACC with Low Speed Follow monitors if a ve hicle 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 vehicle’s set speed in order to keep the
vehicle’s set followi ng-interval from the vehicle ahead.
2To Set or Change Following-Interval P. 414
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 Operation1 When in Operation
If the vehicle ahead of you slows down abruptly, or if
another vehicle is detected cutting in front of you,
the beeper sounds, a message appears on the driver
information interface.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.
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
detected in front of you comes in and goes out of the
ACC with Low Speed Follow detecting range.
