Driving
■There is a vehicle ahead
ACC monitors if a vehicle ahead of you enters the ACC range. If a vehicle is detected
doing so, the ACC system maintains or decele rates 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. 505
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 Operation1When in Operation
If the vehicle detected ahead of you slows down
abruptly, or if a nother vehicle is de tected cutting in
front of you, the beep er sounds and a message
appears on the driver information interface.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.

Driving
■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 th e vehicle speed. In this case, there is no audible or
visual alert even if a ve hicle is in the ACC range.
ACC stays on unless you cancel it. Once you release the accelerator pedal, the
system resumes an appropriate speed for keeping the following-interval while a
vehicle ahead is within the ACC range.
1 When in Operation
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC may start
accelerating your vehi cle 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.
2 Customized Features P. 124, 337
Limitations
You may need to use the brake to maintain a safe
interval when using ACC. Additionally, ACC may not
work properly under certain conditions.
