When ACC with LSF st arts operating, the
vehicle icon, interval bars and set speed
appear on the driver information interface.
When you use ACC with LSF, Straight Driving

■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 ve hicle’s set following-interval from the
vehicle ahead.
2 To Set or Change Following-Interval P. 398
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 Operation1When in Operation
If the vehicle ahead of you slows down abruptly, or if
another vehicle is detected cutting 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.
Even if the interval betw een your vehicle and the
vehicle detected ahead is short, ACC with LSF may
start accelerating your ve hicle 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, gradua lly increasing the interval
between the vehicles.
You can also set the system to beep when a vehicle
detected in front of you co mes 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 th e 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.
■A vehicle detected ahead is within AC C with LSF range and slows to a stop
Your vehicle also stop s, automatically. The
Stopped message appears on the driver
information interface.
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.
1 When in Operation
Limitations
You may need to use the brake to maintain a safe
interval when using ACC wi th LSF. Additionally, ACC
with LSF may not work properly under certain
conditions.
2 ACC with LSF Conditions and Limitations
P. 395
3WARNING
Exiting a vehicle that has been stopped
while the ACC with LSF system is operating
can result in the ve hicle moving without
operator control.
A vehicle that moves without operator
control can cause a crash, resulting in
serious injury or death.
Never exit a vehicle when the vehicle is
stopped by ACC with LSF.
A vehicle icon with dotted-line
contour appears on the driver
information interface
1 When you depress the accelerator pedal
While the accelerator pedal is depressed, the system
does not apply the brakes to keep the following
interval, as well as the BRAKE message on the driver
information interface does not appear.
