■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-distance from the
vehicle ahead.2 To Set or Change Following-distance P. 360
When a vehicle whose speed is slower than
you r se t spe e d c om e s in or cu t s in f r on t of yo u
and is detected by the radar and the camera,
your vehicle starts to slow down.

When in Operation
1When 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 multi-information display.
Depress the brake pedal, and keep an appropriate
distance from the vehicle ahead.
Even if the distance 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 distance
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 LSF detecting range. Change the ACC

■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 the set speed.■A vehicle detected ahead is within ACC with LSF range and slows to a stop
Your vehicle also stops, automatically. The
Stopped message appears on the multi-
information display.
When the vehicle ahead of you starts again,
the vehicle icon on the multi-information
display blinks. If you press the RES/+/SET/–
switch up or down, or depress the accelerator
pedal, ACC with LSF operates again within the
previously set speed.A vehicle icon with dotted-line
contour appears on the multi-
information display
