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.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.
The radar sensor for ACC is shared with the collision
mitigation braking system
TM (CMBSTM).
2 Collision Mitigation Braking SystemTM
(CMBSTM)* P. 318
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 282
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when travelling on open
highways in good weather.
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.

■To Set the Vehicle Speed1Adaptive Cruise Control (ACC)*
Do not use ACC under these conditions:•In poor visibility.
•In heavy traffic.
•When you must slow down and speed up
repeatedly.
•On winding roads.
•When you enter a toll gate, interchange, service
area, parking area, etc. In these areas, there is no
vehicle ahead of you, but ACC would still try to
accelerate to your set speed.
•In bad weather (rain, fog, snow, etc.).
•On a slippery road (for example a road covered
with ice or snow).
•When going down a steep hill where the engine
braking does not work sufficiently.
When not using ACC: Turn off adaptive cruise by

The radar sensor monitors the distance be tween your vehicle and a vehicle ahead of
you. When the sensor detects a change in distance, the system responds by
accelerating or braking your vehicle in orde r to maintain the set speed and following
distance as necessary.
■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 and a message appears on the multi-
information 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 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 fast er than your vehicle.
•A vehicle that cuts in front of you is going faster
than your vehicle, gradua lly distancing itself from
you.
If you do not want to hear a beep when the system
detects a vehicle, or when the vehicle goes out of
ACC range, you can change the pre-running detect
car beep setting.

■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 th e 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 ACC range.
ACC stays on unless you cancel it. Once you release the accelerator pedal, the
system resumes the set speed.
1 When in Operation
Limitations
Be aware that ACC has limitations. For example, it is
not designed to operate wh en a vehicle ahead of
yours is going slower than 12 mph (20 km/h) or is
parked. Smaller vehicles, such as motorcycles, may
also be difficult for the sy stem to detect depending
on their size.
You must always be prepar ed to use the brake pedal
to maintain a safe distan ce with other vehicles.
ACC may momentarily apply br akes or sound an alert
if there is a vehicle or building adjacent to your
vehicle and:
•You make a sudden turn or are driving on a narrow
road.
•You abruptly move the steering wheel.•Your vehicle is unusuall y positioned within your
lane (e.g., at a slight diag onal to the lane direction).
