Do not place an object on the top of the instrument 
panel. It may reflect onto the windshield and prevent 
the system from detecting lane lines properly.

If the Some Driver Assist Systems Cannot 
Operate:Camera Temperature Too High:  
message appears:

•

Use the climate control system to cool down the 
interior and, if necessary, also use defroster mode 
with the air flow directed toward the camera.

•

Start driving the vehicle to lower the windshield 
temperature, which cools down the area around 
the camera.

If the Some Driver Assist Systems Cannot 
Operate:Clean Front Windshield:  

message 

appears:

•

Park your vehicle in a safe place, and clean the 
windshield. If the message does not disappear after 
you have cleaned the windshield and driven for a 
while, have your vehicle checked by a dealer.

Driving

Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)

*

Helps maintain a constant vehicle speed and a set following-interval behind a vehicle 
detected ahead of yours and, if the detected vehicle comes to a stop, can decelerate 
and stop your vehicle, without you having to keep your foot on the brake or the 
accelerator.
When ACC with LSF slows your vehicle by applying the brakes, your vehicle’s brake 
lights will illuminate.

Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)

*

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

3

WARNING

Improper use of ACC with LSF can lead 
to a crash.

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

3

WARNING

ACC with LSF has limited braking 
capability and may not stop your vehicle 
in time to avoid a collision with a vehicle 
that quickly stops in front of you.

Always be prepared to apply the brake 
pedal if the conditions require.

When to use

■

Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with 
LSF range – ACC with LSF operates at speeds up to 90 mph (145 km/h).
No vehicle is detected within ACC with LSF range – ACC with LSF operates at 
the speed of 25 mph (40 km/h) or above.

■

Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)

*

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

ACC with LSF may not work properly under certain 
conditions.

2 ACC with LSF Conditions and Limitations 

P. 488

When not using ACC with LSF: Turn off adaptive 
cruise by pressing the MAIN button. This also will 
turn off the Lane Keeping Assist System (LKAS).

Do not use ACC with LSF 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 with LSF 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.

How to use

When driving at 25 mph (40 km/h) or above: Take your foot off the pedal and 
press the –/SET button when you reach the desired speed. The moment you release 
the button, the set speed is fixed, and ACC with LSF begins.
When driving slower than 25 mph (40 km/h): If the vehicle is moving and the 
brake pedal is not depressed, pressing the button fixes the set speed to 25 mph (40 
km/h) regardless of current vehicle speed. If your vehicle is stationary and a vehicle 
is detected ahead, your vehicle speed can be set, even with the brake pedal 
depressed.

There is a vehicle ahead

ACC with LSF monitors if a vehicle ahead of you enters the ACC with LSF range. If a 
vehicle is detected doing so, the ACC with LSF system maintains or decelerates your 
vehicle’s set speed in order to keep the vehicle’s set following-interval from the 
vehicle ahead.

2 To Set or Change Following-Interval P. 491

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

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, a message appears on the driver information 
interface.
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, ACC with LSF 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 distance 
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 with 
LSF 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 with LSF 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 with LSF range.
ACC with LSF 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 with LSF range.

WARNING

Exiting a vehicle that has been stopped 
while the ACC with LSF system is

moving without operator control.

A vehicle that moves without operator 
control can cause a crash, resulting in

If a vehicle detected ahead is going at a speed slower 
than your increased set speed, ACC with LSF may not 
accelerate your vehicle. This is to maintain the set 
interval between your vehicle and the vehicle ahead.

When you depress the accelerator pedal and then

• When the radar sensor in the front grille 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

• 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.
