Adaptive Cruise Control (ACC)
Helps maintain a constant vehicle speed a nd a set following-interval behind a vehicle
detected ahead of yours, without you havi ng to keep your foot on the brake or the
accelerator.1 Adaptive Cruise Control (ACC)
ACC can not be activated if Intelligent Traction
Management settin g is snow, sand
* or mud*.
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when driving on expressways
or freeways and in good weather
conditions.
3WARNING
ACC has limited braking capability.
When your vehicle speed drops below
22 mph (35 km/h), 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
■Vehicle speed for adaptive cruise control: Desired speed in a
range above roughly 25 mph (40 km/h) ~
■Gear positions for adapti ve cruise control: In (D or (S
The radar sensor is behind
the emblem.
The camera is located
behind the rearview
mirror.

■How to activate the system1Adaptive 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 interval betw een your vehicle and other vehicles.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera P. 459
The radar sensor for ACC is shared with the Collision
Mitigation Braking System
TM (CMBSTM).

How to use

uuHonda Sensing ®u Adaptive Cruise Control (ACC)
434
Driving
Take your foot off the pedal and press down the –/SET button when you reach the
desired speed. The moment you release the –/SET button, the set speed is fixed, and
ACC begins.
When ACC starts operating, the vehicle icon,
distance bars and set speed appear on the
multi-information display.
■To Set the Vehicle Speed1Adaptive Cruise Control (ACC)
ACC may not work properly under certain conditions.
2 ACC Conditions and Limitations P. 437
When not using ACC: Turn off adaptive cruise by
pressing the MAIN button. This also will turn off the
Lane Keeping Assist System (LKAS).
When the MAIN button is pressed, both ACC and
the Lane Keeping Assist System (LKAS) are either
turned on or off.
Do not use ACC under the following conditions:
•On roads with heavy traf fic or while driving in
continuous stop and go traffic.
•On roads with sharp turns.
•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC will not apply the brakes to maintain
the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
You can switch the displayed set speed
measurements on the audio/information screen
between mph and km/h. 2 Customized Features P. 295

■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. 440
■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-information display.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.

ACC Range: 394 ft. (120 m)

uuHonda Sensing ®u Adaptive Cruise Control (ACC)
436
Driving
When a vehicle whose sp eed is slower than
your set speed is detected in front of you, your
vehicle starts to slow down.
■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. 295
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.
