Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed and a set following-distance behind a
vehicle detected ahead of yours, without you having to keep your foot on the brake
or the accelerator.
When ACC slows your vehicle by applying the brakes, your vehicle’s brake lights will
illuminate.1 Adaptive Cruise Control (ACC)*
Important Reminder
As with any system, there are limits to ACC. Use the
brake pedal whenever necessary, and always keep a
safe distance between your vehicle and other
vehicles.
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below 22
mph, ACC will automatically cancel and no
longer will apply your vehicle’s brakes.
Always be prepared to apply the brake
pedal when conditions require.
When to use

■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-distance from the vehicle ahead.
2To Change Vehicle Distance P. 362
■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 multi-informat ion display to alert you
to brake.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance 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 distancing itself from
you.
You can also set the system to beep when a vehicle
detected in front of you co mes in and goes out of the
ACC detecting range. Change the ACC Forward

■There is no vehicle ahead
Your vehicle cruises at the set speed.
■A vehicle ahead is within ACC range and going slower than the set speed
Your vehicle slows down, and maintains the same speed as the speed of the vehicle
ahead to maintain the set following distance.
■A vehicle ahead is within ACC ra nge and going at a steady speed
Your vehicle follows the vehicle ahead of it, keeping a constant distance, without
going beyond the set speed.
■A vehicle ahead goes out of range
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 alerts even if a vehicle is in 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.
