Continuously variable transmission models  
Adaptive Cruise Control (ACC) with Low Speed  
Follow (LSF)  
Helps to 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.  
1Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)  
3WARNING  
Improper use of ACC with LSF can lead to a  
crash.  
Use ACC with LSF only when driving on  
motorways and in good weather  
conditions.  
When ACC with LSF slows your vehicle by applying the brakes, your vehicle’s brake  
lights will illuminate.  
When to use  
The camera is  
located behind  
the rearview  
mirror.  
3WARNING  
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.  
The radar sensor is inside the  
front grille.  
Important Reminder  
As with any system, there are limits to ACC with LSF.  
Use the brake pedal whenever necessary, and always  
keep a safe interval between your vehicle and other  
vehicles.  
Vehicle speed for ACC with LSF: A vehicle is detected ahead within ACC with  
LSF range – ACC with LSF operates at speeds up to 180 km/h (112 mph).  
No vehicle is detected within ACC with LSF range – ACC with LSF operates at  
the speed of 30 km/h (18 mph) or above.

1To Set the Vehicle Speed  
You can switch the displayed set speed  
measurements on the driver information interface or  
audio/information screen between km/h and mph.  
2 Speedometer P. 147  
When driving at about 30 km/h (18 mph) 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 at slower than about 30 km/h (18 mph): If the vehicle is moving  
and the brake pedal is not depressed, pressing the button fixes the set speed to  
about 30 km/h (18 mph) regardless of current vehicle speed.  
2 Customized Features P. 158, 413  
If your vehicle is stationary, you can set the vehicle speed even with the brake pedal  
depressed.

Set Vehicle Interval  
When you use ACC with LSF, Straight Driving  
Assist (a feature of the Electric Power Steering  
system) is activated.  
By enabling the steering system to

1When in Operation  
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, and the head-up warning lights* flash.  
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. 583  
Depress the brake pedal, and keep an appropriate  
interval from the vehicle ahead.  
ACC with LSF Range: 120 m  
When a vehicle whose speed is slower than  
your set speed is detected in front of you, your  
vehicle starts to slow down.

1When in Operation  
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 travelling at  
the set speed, ACC with LSF accelerates your  
vehicle to the set speed, and then maintains it.  
Even if the interval between your vehicle and the  
vehicle detected 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 interval  
between the vehicles.  
A vehicle icon with dotted-line  
contour appears on the driver  
information interface  
You can also set the system to beep when a vehicle  
detected in front of you comes in and goes out of the  
ACC with LSF detecting range. Change the ACC  
Vehicle Ahead Detected Beep setting.  
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.  
2 Customized Features P. 158, 413  
Limitations  
You may need to use the brake to maintain a safe  
interval when using ACC with LSF. Additionally, ACC  
with LSF may not work properly under certain  
conditions.

When the vehicle ahead of you starts again,  
the vehicle icon on the driver information  
interface blinks. If you press the RES/+ or  
–/SET button, or depress the accelerator  
pedal, ACC with LSF operates again within the  
prior set speed.  
Exiting a vehicle that has been stopped  
while the ACC with LSF system is operating  
can result in the vehicle moving without  
operator control.  
A vehicle that moves without operator  
control can cause a crash, resulting in  
serious injury or death.  
If no vehicle is ahead of you before you  
resume driving, depress the accelerator pedal  
and ACC with LSF will operate again within  
the prior set speed.  
Never exit a vehicle when the vehicle is  
stopped by ACC with LSF.

1To Adjust the Vehicle Speed  
To Adjust the Vehicle Speed  
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.  
Increase or decrease the vehicle speed using the RES/+ or –/SET button on the  
steering wheel.  
To increase speed  
When you depress the accelerator pedal and then  
push and release the –/SET button, the current speed  
of the vehicle is set.  
To decrease speed  
Each time you press the RES/+ or –/SET button, the vehicle speed is increased or  
decreased by about 1 km/h or 1 mph accordingly.  
If you press and hold the RES/+ or –/SET button, the vehicle speed increases or  
decreases by about 10 km/h or 10 mph accordingly.
