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 FCW
(Forward Collision Warning).
2 Forward Collision Warning (FCW)
* P. 456

WARNING
Improper use of ACC can lead to a crash.
Use ACC only when traveling on open
highways in good weather.

WARNING
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 cruise control:
Desired speed in a ran ge above roughly 25
mph (40 km/h) ~■Shift positions for adaptive cruise control:
In ( D or
(S
The radar sensor is inside the front

1Adaptive 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 a spare tire is installed.•When going down a steep hill where the engine
braking does not work sufficiently.
When not using adaptive cruise control: Turn off
adaptive cruise by pressing the MAIN button.

The radar sensor monitors the distance between your vehicle and a vehicle ahead of
you. When the sensor detects a change in distance, the system responds it by
accelerating or braking your vehicle in order to maintain the set speed and following
distance as necessary.■
When in Operation
1 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 between your vehicle and the
vehicle ahead is short, FCW 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 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. 2 Customized Features P. 97, 298

■When ACC detects a
vehicle within ACC range:
■When the vehicle goes
out of ACC range:
The beeper sounds once and
the vehicle icon appears on the
multi-information display. The beeper sounds once

Driving
■There is no vehicle ahead
Your vehicle cruises at the set speed.■A vehicle ahead is within ACC range an d 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 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
Be aware that ACC has limitations. For example, it is
not designed to operate when a vehicle ahead of
yours is going slower than 13 mph (20 km/h) or is
parked. Smaller vehicles, such as motorcycles, may
also be difficult for the system to detect depending
on their size.
You must always be prepared to use the brake pedal
to maintain a safe distance with other vehicles.
ACC may momentarily apply brakes 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 unusually positioned within your
lane (e.g., at a slight diagonal to the lane direction).

Increase or decrease the vehicle speed using the RES/+ or –/SET buttons on the
steering wheel.
• Each time you press the button, the vehicle speed is increased or decreased by
about 1 mph or 1 km/h accordingly.
• If you keep the button pressed, the vehicle speed increases or decreases by about
5 mph or 5 km/h accordingly.
Press the (distance) button to change ACC
range.
Each time you press the button, the following
distance (the distance behind a vehicle
detected ahead of you) setting cycles through
short, middle, long, and extra long following
distances.■
To Adjust the Vehicle Speed
1 To Adjust the Vehicle Speed
If a vehicle 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 distance
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.
