Automatic cancellation

The beeper sounds and a message appears on the driver information interface when 
ACC with LSF is automatically canceled. Any of these conditions may cause the ACC 
with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the lower bumper gets dirty.
• The vehicle ahead of you cannot be detected.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA® or CMBS

TM

 is activated.

• When the ABS or VSA® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the ACC with LSF range is too close to your 

vehicle.

• The camera behind the rearview mirror, or the area around the camera, including 

the windshield, gets dirty.

• When the Maximum Load Limit is exceeded.
• When passing through an enclosed space, such as tunnel.

The ACC with LSF automatic cancellation can be also triggered by the following 
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastened when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The engine is turned off.

Automatic cancellation

Even though ACC with LSF has been automatically 
canceled, you can still resume the prior set speed. 
Wait until the condition that caused ACC with LSF to 
cancel improves, then press the –/SET button.

Driving

Press and hold the   (interval) button for one 
second. Cruise Mode Selected appears on 
the driver information interface for two 
seconds, and then the mode switches to 
Cruise.
To switch back to ACC with LSF, press and 
hold the   button again for one second. ACC 
Mode Selected
 appears on the driver 
information interface for two seconds.

When to use

Desired speed in a range above roughly 25 mph (40 km/h) ~.

Take your foot off the pedal and press the –/SET button when you reach the desired 
speed.
The moment you release the –/SET button, the set speed is fixed, and cruise control 
begins. The CRUISE CONTROL indicator comes on.

When you use cruise control, Straight Driving Assist (a feature of the Electric Power 
Steering system) is activated.
By enabling the steering system to automatically compensate for natural steering 
pull, Straight Driving Assist makes it easier for you to keep your vehicle in a straight 
line.

Resuming the prior set speed:
After cruise control has been canceled, you can still 
resume the prior set speed by pressing the RES/+ 
button while driving at a speed of at least 25 mph (40 
km/h) or more.

You cannot set or resume in the following situations:

When vehicle speed is less than 25 mph (40 km/h)

When the MAIN button is turned off.

Important Reminder
As with any system, there are limits to ACC. Use the 
brake pedal whenever necessary, and always keep a 
safe interval between your vehicle and other vehicles.

The radar sensor for ACC is shared with the collision 
mitigation braking system

).

WARNING

Improper use of ACC can lead to a crash.

Use ACC only when driving on 
expressways or freeways and in good 
weather conditions.

3

WARNING

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 position for ACC: In 

(

2 or higher position.

The radar sensor is in the 
lower bumper.

Be careful not to have 
the radar sensor cover 
strongly impacted.

The camera is 
located behind the 
rearview mirror.

camera equipped with this system.

Front Sensor Camera P. 526

When the MAIN button is pressed, ACC and Lane 
Keeping Assist System (LKAS) are both turned on or 
off.

ACC may not work properly under certain conditions.

ACC Conditions and Limitations P. 504

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 traffic 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 facilities with drive through access.

When the engine speed slows down, try to 
downshift.
When the engine speed goes up, try to upshift.
You can maintain the set speed if you change gear 
within five seconds.

How to use

Press the MAIN button on 
the steering wheel.

ACC (green) is on in the instrument panel.

Take your foot off the pedal and press down the /SET button when you reach the 
desired speed. The moment you release the button, the set speed is fixed, and ACC 
begins.

When ACC starts operating, the vehicle icon, 
interval bars and set speed appear on the 
driver information interface. 

When you use ACC, Straight Driving Assist (a 
feature of the Electric Power Steering system) 
is activated.

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 decelerates your vehicle’s set speed in order 
to keep the vehicle’s set following-interval from the vehicle ahead.

To Set or Change Following-Interval P. 508

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 Operation

When in Operation

If the vehicle detected ahead of you slows down 
abruptly, or if another vehicle is detected cutting in 
front of you, the beeper sounds and a message 
appears on the driver information interface.

Depress the brake pedal, and keep an appropriate 
interval from the vehicle ahead.

Driving

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. In this case, there is no audible or 
visual alert even if a vehicle 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 between your vehicle and the 
vehicle detected 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, gradually 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.

Customized Features P. 124, 337

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.

than your increased set speed, ACC may not 
accelerate your vehicle. This is to maintain the set
