When driving at about 30 km/h (18 mph) or above: 

Take your foot off the 

pedal and press the

When driving 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 
30 km/h (18 mph) regardless of current vehicle speed. If your vehicle is stationary, 
you can set the vehicle speed even with the brake pedal depressed.

■

There is a vehicle ahead

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

When a vehicle whose speed is slower than 
your set speed comes in or cuts in front of you 
and is detected by the radar and the camera, 
your vehicle starts to slow down.

■

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 
interval from the vehicle ahead.

Adaptive Cruise Control (ACC) with Low Speed Follow

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 travelling at 
the set speed, ACC with Low Speed Follow 
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 Low Speed Follow range.
ACC with Low Speed Follow 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 Low Speed Follow 
range.

1

When in Operation

Even if the interval between your vehicle and the 
vehicle detected ahead is short, ACC with Low Speed 
Follow 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 
detected in front of you comes in and goes out of the 
ACC with Low Speed Follow detecting range.

A vehicle detected ahead is within ACC with Low Speed Follow range and

When the vehicle ahead of you starts again, 
the vehicle icon on the gauge blinks. If you 
press the

 or 

SET/−

 button, or depress 

the accelerator pedal, ACC with Low Speed 
Follow operates again within the previously 
set speed.

If no vehicle is ahead of you before you 
resume driving, depress the accelerator pedal 
and ACC with Low Speed Follow will operate 
again within the prior set speed.

WARNING

Exiting a vehicle that has been stopped 
while the ACC with Low Speed Follow 
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.

•

When the radar sensor in the front grille gets dirty.

•

The vehicle ahead of you cannot be detected.

•

An abnormal tyre condition is detected, or the tyres are skidding.

•

•

Abrupt steering wheel movement.

•

When the ABS, VSA or CMBS is activated.

•

•

When the vehicle is stopped on a very steep slope.

•

When you manually apply the electric parking brake.

•

When the detected vehicle within the ACC with Low Speed Follow range is too 
close to your vehicle.

•

The camera behind the rearview mirror, or the area around the camera, including 
the windscreen, gets dirty.

How the system works

The radar sensor in the front grille detects 
vehicles ahead of you including those in the 
adjacent lane, and the camera behind the 
rearview mirror detects the lane markings.

This system improves ACC with Low Speed 
Follow's following/tracking property; it adjusts 
your vehicle speed in advance predicting a 
situation that a vehicle running in the adjacent 
slower lane catches up with a slower vehicle 
ahead of it and changes the lane to cut in 
front of you early.
When such a cut-in situation is predicted, your 
vehicle speed decreases a little. When 
detected, your vehicle speed decreases 
according to the vehicle cutting in front of 
you.

As the speed is adjusted by the system, the cut 
in vehicle icon appears on the gauge to 
indicate that the system is activated.

Left-hand drive type is shown.
