ACC (Adaptive Cruise Control)*
Maintains a constant vehicle speed and a safe distance between your vehicle and the
vehicle ahead of you without having to keep your foot on the brake pedal or
accelerator.1 ACC (Adaptive Cruise Control)*
Important Safety Reminder
As with any system, th ere are limits to ACC.
Inappropriate use of ACC can result in a serious
accident. 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 CMBS
TM
(collision mitigation braking systemTM).

SystemTM)* P. 257
3WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.When to use
■Vehicle speed for adaptive cruise control:

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 a spare tire is installed.•When going down a steep hill where the engine
braking does not work sufficiently.

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 compensates it by
accelerating or braking your vehicle in order to maintain the cruising speed you
previously set.
■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 ap pears on the multi-
information display to alert you.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead. 2 CMBS
TM (Collision Mitigation Braking
SystemTM)* P. 257
If the CMBS
TM has been turned off, there is no
audible or visible alert available.
Even if the distance between your vehicle and the
vehicle ahead is short, CMBS
TM may not alert you or
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 cuts in front of you is going faster than
your vehicle, gradually distancing.
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. 2 Customized Features P. 94
■When ACC detects a
vehicle within ACC range:■When the vehicle goes
out of ACC range:
a beeper sounds once and a
vehicle icon appears on the
multi- information display. a beeper so
unds once and
the vehicle icon on the
multi- information display
becomes a dotted-line
contour.

Driving
■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.
■A vehicle ahead is within ACC range 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 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
Use the brake pedal to mainta in a safe distance with
other vehicles in the follo wing cases. ACC may not
work properly when:
•Vehicles ahead of you are going slower than 13
mph (20 km/h) or vehicles are parked.
•Motorcycles or other small vehicles are ahead of
you.
ACC may momentarily apply brakes or sounds a beep
against a vehicles beside you or even a building
beside you if:
•You drive at a sudden curve or on a narrow road.•You abruptly move the steering wheel.•You are in an unusual position within your lane.
