brake pedal whenever necessary, and always keep a
safe interval betw een your vehicle and other vehicles.

doing so, the ACC system maintains or decele rates your vehicle’s set speed in order
to keep the vehicle’s se t 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 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 alerts even if a vehicle is in the ACC range.
ACC 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.
1 When in Operation
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC 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, 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
detecting range. Change the ACC Forward Vehicle
Detect Beep setting.
