Adaptive Cruise Control (ACC)*
Helps maintain a constant vehicle speed and a set following interval behind a vehicle
detected ahead of yours, without you having to keep your foot on the brake or the
accelerator.1Adaptive 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.
Be careful not to have the radar sensor cover strongly
impacted.
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
■Vehicle speed for adaptive crui se control: Desired speed in a
range above roughly 25 mph (40 km/h) ~
■Shift positions for adaptive cruise control: In ( D
The radar sensor is in the
front grille.
The camera is located
behind the rearview
mirror.

■How to activate the system1Adaptive Cruise Control (ACC)*
When the MAIN button is pressed, both ACC and
the Lane Keeping Assist System (LKAS) are either
turned on or off.
ACC may not work properly under certai n conditions.
2 ACC Conditions and Limitations P. 462
When not using ACC: Turn off adaptive cruise by
pressing the MAIN button. This also will turn off the
Lane Keeping Assist System (LKAS).
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.
■Press the MAIN button on
the steering wheel.
ACC (green) is on in the
multi-information display.
Adaptive cruise control is
ready 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 se t following interval from the vehicle ahead.
2To Set or Change Following Interval P. 465
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 cuts in front of you, the beeper
sounds, a message appears on the multi-information
display.
Depress the brake pedal, and keep an appropriate
interval from the vehicle ahead.
Even if the interval betw een your vehicle and the
vehicle 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.

■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.
ACC stays on unless you cancel it. Once you release the accelerator pedal, the
system resumes the set speed or a suffici ent speed to keep the following interval.
1When you depress the accelerator pedal
While the accelerator pedal is depressed, the system
does not apply the brakes to keep the following
interval, as well as the BRAKE message on the multi-
information display does not appear. 2 When in Operation P. 460
A vehicle icon with dotted-line
contour appears on the multi-
information display.

■Environmental conditions
Driving in bad weather (r ain, fog, snow, etc.).
■Roadway conditions
Driving on a snowy or wet roadway (obscure d lane marking, vehicle tracks, reflected
lights, road spray, high contrast).
■Vehicle conditions
• The outside of the windshie ld is blocked by dirt, mud, leaves, wet snow, etc.
• An abnormal tire or wheel condition (wrong sized, varied size or construction,
improperly inflated, comp act spare tire, etc.).
• The camera temperature gets too high.
• The parking brake is applied.
• When the radar sensor cover is dirty.
• The vehicle is tilted due to a heav y load or suspension modifications.
• When tire chains are installed.
■ACC Conditions and Limitations1ACC Conditions and Limitations
The radar sensor for ACC is shared with the collision
mitigation braking system
TM (CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM)* P. 494
Do not put a sticker on the radar sensor cover or
replace the radar sensor cover.
Have your vehicle checked by a dealer if you find any
unusual behavior of the system (e.g., the warning
message appears too frequently).
If the front of the vehicle is impacted in any of the
following situations, the ra dar sensor may not work
properly. Have your vehi cle checked by a dealer:
•The vehicle mounted onto a bump, curb, chock,
embankment, etc.
•You drive the vehicle where the water is deep.
•Your vehicle has a frontal collision.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera

Increase or decrease the vehicle speed using the RES/+ or –/SET buttons on the
steering wheel.
• Each time you press the button, the vehicl e speed is increased or decreased by
about 1 mph or 1 km/h accordingly.
• If you keep the button pressed, the vehicl e speed increases or decreases by about
5 mph or 5 km/h accordingly.
■To Adjust the Vehicle Speed1 To Adjust the Vehicle Speed
If a vehicle detected ahead is going at a speed slower
than your increased set speed, ACC may not
accelerate your vehicle. This is to maintain the set
following interval between your vehicle and the
vehicle ahead.
You can set the vehicle speed using the –/SET button
on the steering wheel when adjusting the speed with
the accelerator and brake pedals.
